Introducing the Auphonic Command Line Interface (CLI)

grh@auphonic.com (Georg) — Thu, 26 Mar 2026 06:55:42 +0000

Auphonic is now available from the command line:
The Auphonic CLI lets you process, manage, and automate audio productions without leaving the terminal. It's a free, single binary with no dependencies — just download it, authenticate, and start processing.

Everything you know from Auphonic is available: Noise Reduction, Loudness Normalization, Speech Recognition, Multitrack Processing, Presets, and publishing to External Services. All from a single command.

Use Cases

Whether you're producing a single episode or processing thousands of files, the CLI fits into a wide range of workflows:

File-based workflows: If you're a broadcaster, podcaster, or anyone working with file-based audio, the CLI lets you integrate Auphonic directly into your local workflow. Drop it into your existing production pipeline and process files right where they live — no browser required.

DAW integration: Pipe audio straight from ffmpeg, sox, or your DAW exports into Auphonic. This makes it easy to add post-processing as the final step in your editing workflow without switching tools.

Batch processing & scripting: Wrap the CLI in a shell script, cron job, or CI/CD pipeline to process entire folders of files automatically. Great for teams that need to handle high volumes of audio with consistent quality settings.

Optimized for humans and agents: A single command replaces what would otherwise be multiple API calls with HTTP requests, JSON payloads, and auth headers. The CLI is designed to be easy to use interactively, but its structured output also makes it a natural fit for AI agents and LLMs that need to integrate audio processing into their toolchains.

Examples

Processing a file is as simple as a single command. The CLI uploads your audio to Auphonic, applies our default audio algorithms automatically, and downloads the processed result back to your machine:

Terminal

# Process an audio file, wait for completion, and download the result
$ auphonic process interview.wav --wait --download
Processing interview.wav...
Status: Done
Downloaded: interview-auphonic.mp3

Presets save your production settings — output formats, loudness targets, metadata, publishing destinations — so you get consistent results across episodes without repeating yourself. The --preset flag accepts either the preset name or its UUID. You can also pipe audio from other tools like ffmpeg:

Terminal

# Apply a preset to your production
$ auphonic process episode.wav --preset "My Podcast" --wait --download
# Pipe audio from ffmpeg
$ ffmpeg -i recording.mkv -vn -f wav - | auphonic process - --preset "My Podcast"

Need to check on past productions or grab a result file? The list and download commands let you quickly browse your production history and pull output files. Add --open to open the production in your browser, or use auphonic open UUID to jump to any production at any time:

Terminal

# List recent productions
$ auphonic list
UUID                    Status    Title
aB3xKmNpQrStUvWxYz1234  Done      Episode 42
zY9wLcFgHjKmNpQrSt5678  Done      Interview
# Download a production's output files
$ auphonic download aB3xKmNpQrStUvWxYz1234
# Open a production in the browser
$ auphonic open aB3xKmNpQrStUvWxYz1234

Multitrack productions let you process separate audio tracks for each speaker or source — Auphonic automatically balances levels, reduces crosstalk, and mixes them into a final file. This is ideal for interviews, panel discussions, or any recording with multiple microphones:

Terminal

# Multitrack production with labeled tracks
$ auphonic process \
  --track id=host,file=host.wav \
  --track id=guest,file=guest.wav \
  --track id=music,file=music.wav \
  --wait --download

You can add Speech Recognition to generate transcripts alongside your processed audio, publish directly to an External Service like your podcast host or YouTube, or set default options so you don't have to repeat them every time:

Terminal

# Add speech recognition
$ auphonic process episode.wav --speech-recognition --wait
# Publish to your podcast host
$ auphonic process episode.wav --publish SERVICE_UUID --wait
# Set a default preset for all future productions
$ auphonic config set default-preset "My Podcast"

See the CLI reference documentation for the full command reference.

Auphonic API Updates

Alongside the CLI, we've made some improvements to the Auphonic API that benefit both API users and CLI users alike.

OpenAPI specification: The Auphonic API now has a full OpenAPI 3.0.3 specification covering all endpoints. In practice, this means you can auto-generate client libraries in your language of choice, get autocompletion in your IDE, and validate requests before sending them. You can also browse the full API interactively via ReDoc.

Preset names in API: You can now reference presets by name instead of UUID in API calls — no more copying opaque identifiers. The CLI uses this feature under the hood, which is why --preset "My Podcast" works out of the box. If multiple presets share a name, priority goes to personal presets first, then shared, then default. See the API documentation for details.

Get Started

The CLI runs on macOS, Linux, and Windows. Install it with a single command:

Terminal

$ curl -sSL https://auphonic.com/cli/install.sh | sh
# Authenticate with your Auphonic account
$ auphonic auth login

You can also download pre-built binaries directly from auphonic.com/cli, where you'll find setup instructions for all platforms.
For the full command reference, see the CLI documentation.

Feedback

The CLI is a new addition to Auphonic, and we'd love to hear how it works for you. If you have feedback, run into issues, or have ideas for new features, please visit our Contact Page or email us at support@auphonic.com.

New External Services: RSS.com, Acast, Scrybecast

cg@auphonic.com (Christoph) — Fri, 06 Mar 2026 11:03:41 +0000

We built Auphonic to remove friction from podcast production.

In our view, you should be able to focus on your content, while the technical work happens reliably in the background. And when you're happy with your results, you can export your production directly to your hosting platform. And if your hosting platform isn't on the list yet — you can build your own integration using our API.

That philosophy shapes everything we build - from Loudness Normalization, to Noise Reduction, to Production Presets.

External Publishing builds on this idea: delivering your episode to your hosting platform without unnecessary downloads, re-uploads, or duplicated metadata entry.

You process your production once. Auphonic takes care of the delivery.

Why We Built External Publishing

Publishing your podcast manually is repetitive and it's easy to make mistakes: download, re-upload, copy metadata, and double-check everything.

External Publishing removes these steps. Connect your platform once and select it directly in your Production Settings.

After processing, Auphonic delivers your file and metadata automatically. If needed, you can enable Review before Publishing to approve the result before delivery.

Publish automatically, or review before delivery.

New Integration: Publish Directly to RSS.com, Acast, Scrybecast

We are happy to announce new integrations with RSS.com, Acast, and Scrybecast!

You can now export your productions directly from Auphonic to your chosen platform.

To set this up, go to your Services and add a new service.

Enter the name you want to have shown for your service and the API key provided by the hosting platform.

Enter your API key - provided by your platform - and the name you want to be shown in Auphonic. Save the service, then select it in your future productions.

You can then select and use these external services in your production workflow.

Once processing is complete, Auphonic uploads the final file and sends it directly to your platform. Your production appears on the platform automatically. No downloading and re-uploading needed!

Build Your Own Integration (Like Scrybecast Did)

You can build your own integrations - you are not limited to the ones we provide.

External Publishing works via a simple API. If your platform has an API, you can connect it to Auphonic.

Scrybecast is a perfect example: they built the integration themselves using our External Services API.

In practice, this means:

You define how your service receives audio and metadata
You connect it via API key
Auphonic handles the rest of the workflow

With modern coding tools and LLMs, setting this up is no longer limited to experienced developers. We only step in for review and activation. The integration itself is fully in your control.

Check out our External Services API documentation to get started.

Supported External Publishing Platforms

External Publishing is designed to support a wide range of platforms. All services can be managed in your connected External Services.

File Transfer: FTP, SFTP, Dropbox, Google Drive, OneDrive, Amazon S3, S3 Storage, Archive.org, WebDAV, Google Cloud, Zapier
Podcast & Video Platforms: YouTube, Libsyn, Spreaker, Blubrry, Facebook, SoundCloud, Captivate, PodBean, LetsCast.fm, Podlove, Buzzsprout, Podcaster.de, SquadCast, Hindenburg, Audition, Premiere, RSS.com, Acast, Scrybecast
Speech Recognition: Wit.ai, Google, Amazon, Speechmatics

Simple Audio Production by Design

Our goal is straightforward: make professional audio production accessible without requiring technical expertise.

You focus on your content. Auphonic handles processing, formatting, and delivery.

If you have feedback or would like to see additional integrations, please visit our Contact Page or email us at support@auphonic.com.

Automatically Cut Music Segments from Your Productions

lukasm@auphonic.com (Lukas) — Wed, 11 Feb 2026 12:10:52 +0000

We’ve expanded our Automatic Cutting feature to make it even more useful for broadcast and long-form productions. You can now remove entire music segments with Auphonic. For example, songs in radio shows, podcasts, or recorded broadcasts, which must be removed due to licensing restrictions.

In many broadcasting workflows, this is not just a convenience but a requirement: music may be included in live transmissions, but archived or on-demand versions are often not permitted to make that music permanently available. Automatic music removal ensures compliance while keeping spoken content intact.

Designed for Longer Music Segments

The new Cut Music option is optimized for longer music tracks, like full songs or extended musical interludes. Typical use cases include:

Radio broadcasts with songs between interviews
Live shows with music breaks
Recordings where only spoken content should remain

Once enabled, Auphonic detects these music sections and removes them for you.

Auphonic Editor with Cut Music Segments

Refine your Automatic Results in the Auphonic Editor

The new Music Cutting Feature automatically cuts music segments, and lets you refine these cuts in the Auphonic Editor. Auphonic does the heavy lifting, and you decide exactly what stays and what goes.

Start with our Automatic Cuts and then fine-tune them by ear in the same interface. You can:

Zoom in and click on a cut to select it
Activate or Deactivate Cuts
Create your own custom cuts
Adjust cut regions to your liking and refine by ear

This combined workflow is the same philosophy we use in our Denoising Region Editor, where you refine the automatic denoising Auphonic applies to get exactly the output you're looking for.

NOTE: When you're happy with your cuts, press Apply Changes to reprocess with your new edits. Reprocessing your production will not cost any extra credits.

Cut Music vs. Speech Isolation

It’s important to distinguish between removing entire music tracks and removing background music.

Cut Music removes complete music segments from your production.

Speech Isolation (found under Noise Reduction) is the right tool for removing background music underneath speech.

You’ll find the option to remove music segments in the Automatic Cutting section of your production settings. Simply enable Cut Music, process your audio, and Auphonic will take care of the rest.

If you want to remove background music from your recording, use Noise Reduction > Speech Isolation. Here is additional information on how Auphonic Denoising works, and how we tackle the complex problem of automatically improving audio recordings.

As always, the goal is to save time while keeping full control over your final output.

Feedback

We’re continuously improving Auphonic based on real production workflows. If you have feedback, ideas or want us to think of other features, please reach out via our Contact Page.

You can always send us an email to support@auphonic.com, or give feedback on our results page.

RMS Loudness Normalization for Audible / ACX

grh@auphonic.com (Georg) — Thu, 15 Jan 2026 06:59:41 +0000

Audiobook production has a uniquely stressful property: technical delivery specs are strict, and a single out-of-range file can delay an entire release. Audible / ACX is a common example with strict criteria that uploaded files need to fulfil before they're accepted.

That’s why we’ve added an additional loudness normalization method in Auphonic: RMS-based normalization. It’s designed specifically for workflows that need RMS targets, including Audible / ACX.

What ACX requires (loudness and peaks)

ACX asks for each file to meet a level measured in RMS and a maximum peak limit. The headline values as stated in their ACX audio submission requirements are:

Average level: between -23 dB RMS and -18 dB RMS (per file)
Peak level: peaks must be below -3 dB

In practice, this means you need two things: a consistent overall level, and enough headroom so transients never exceed the peak ceiling.

Recommended ACX settings in Auphonic

If you want one simple, reliable starting point, use the preset below.
It targets the middle of the ACX RMS window and applies the correct peak ceiling.

Web Interface

In the Production Form, open Loudness Normalization and set:

Loudness Target: -20 dBRMS (Audible / ACX)
Maximum Peak Level: -3 dBTP
Normalization Method: RMS Levels (Audible / ACX)

Recommended Auphonic Loudness Normalization settings for Audible / ACX: -20 dBRMS, -3 dBTP, RMS Levels

Learn more about the Auphonic Loudness Normalization Settings!

API

For API users, send the parameter:

"loudnessmethod": "rms", "loudnesstarget": -20

Learn more about How the Auphonic API works!

LUFS vs RMS: why loudness measurement matters

Different measurement methods answer slightly different questions. Some aim to reflect how loud audio is perceived by a listener, others describe the average signal energy over time. Both are valid, but they are not interchangeable - and this distinction is exactly where ACX-related issues originate.

Understanding the difference helps explain why the same audio file can appear “in range” in one tool and fail a check in another.

Interested in learning more?
Here are detailed articles on How Loudness Normalization works in Auphonic.

LUFS: standardized perceived loudness

LUFS (Loudness Units relative to Full Scale) is a standardized loudness measurement defined in international broadcast standards. Its goal is to reflect perceived loudness as consistently as possible across different types of content.

To achieve this, LUFS measurements:

apply frequency weighting to approximate human hearing sensitivity
measure loudness over time, not just instant levels
use gating to reduce the influence of very quiet passages and long silences

This makes LUFS particularly robust for spoken-word content, music, and mixed material. Long pauses between sentences or chapters don’t disproportionately lower the loudness value, which means LUFS tends to align well with how loud a listener experiences the program overall.

RMS: average signal energy

RMS (Root Mean Square) is a way of calculating the signal energy that is no longer commonly used for loudness targets today. It measures the average energy of the audio signal over time, without attempting to model human perception.

In contrast to LUFS:

RMS does not apply perceptual frequency weighting
RMS typically does not include standardized gating
silence and very quiet passages directly lower the average value

This means RMS values are strongly influenced by pauses, gaps between phrases, and overall dynamics. Two narration files with identical spoken content but different pause lengths can produce noticeably different RMS readings.

Why this matters for ACX

ACX specifies its loudness requirements in terms of RMS.

For audiobook production, this difference is crucial. ACX requires every individual file to fall within a strict RMS range, and even a small deviation can lead to rejection and delays in publication.

Auphonic’s LUFS normalization has been used by many producers over the years. But if your workflow is built around RMS targets, or you want a method that aligns more directly with ACX’s published wording, RMS normalization is now available.

Feedback

We’re continuously improving Auphonic based on real production workflows. If you have feedback on RMS normalization for audiobooks, ideas or wishes for other features or feeback for existing ones, please reach out via our Contact Page, email support@auphonic.com, or send us feedback on our results page.

Denoising Editor: Choose Where (and How) to Reduce Noise

lukasm@auphonic.com (Lukas) — Tue, 02 Dec 2025 09:41:33 +0000

With our new Denoising Segment Editor feature, you can now control exactly where and how to reduce noise inside a production: Refine our automatically generated denoise segment boundaries, choose different denoising methods per segment, or switch denoising off completely for things like jingles, embedded music, or sound effects.

The result: you only clean what really needs cleaning, gain more creative control, and work with much higher precision inside a single production.

Only Denoise the Parts That Need It

Many productions contain a mixture of different situations:

Music jingles or sound effects combined with noisy speech
A clean studio introduction followed by a noisy on-location interview
Speech combined with short news clips, where ambiance and noises should not be removed
A short section where a fan or laptop noise becomes audible

Segment-Based Denoising lets you target specific segments of your production, and leaves the rest of the file untouched. The segments are created automatically by our Dynamic Denoiser, which classifies the noise conditions of your audio and generates initial segment boundaries. You can refine these segments manually now - similar to how you adjust cuts in our Cut Editor.

It is also possible to exclude denoising entirely in segments where you don’t want it at all - for example Jingles, embedded music, sound design elements, or external audio inserts.

Auphonic Editor with Output and Input waveforms and editable denoise segments

How Segments Work

The new segment editor for denoising is an additional layer on top of our Auphonic Editor:

You can split existing segments wherever you like.
You can move segment boundaries to match words, pauses, or noisy events more precisely.
You can create a sequence of smaller segments inside one automatic segment if needed.

The automatically detected segments give you a fast starting point which you can adjust for perfect results.

Denoising Segments in multiple colors - change methods or turn denoising on/off per segment

Every segment on the Denoiser layer can have its own processing setting. For each segment you can: turn denoising on or off completely or select which denoising method you want to use - for example our Speech Isolation, Static & Music Denoiser, or Classic Denoiser.

This keeps the interface simple and consistent. You only decide where to reduce noise and which algorithm to use.

How to Use Segment-Based Denoising

Run your production with Noise Reduction
Open the production result page to see our Auphonic Editor
Split or move segment boundaries in the Denoiser layer
Select the desired denoising method for that segment, or turn denoising off
Press Apply Changes or Edit Production to reprocess (reprocessing these edits does not consume additional credits)

Try our new Segment-Based Denoising now!

Conclusion

Noise in your recordings changes over time, so it makes sense that your denoising settings can change as well.
Segment-Based Denoising lets you:

Denoise only the parts that actually need it
Combine multiple denoising methods in a single production
Fix misclassified or delicate sections without touching everything else
Work with more precision while keeping the workflow simple

Open a finished production in our Auphonic Editor, switch to the Denoiser view, and start experimenting with segments.
You will quickly hear how much more control you gain over the sound of your final output.

Segment-Based Denoising is a major step in our broader direction: blend powerful automation with precise human refinement. Expect more features following this philosophy to arrive next year.

Feedback

As with all new features, we are very interested in how you use Segment-Based Denoising in your workflows. If you have feedback, questions, or suggestions, please Contact Us or send us a message via the production feedback form.

Multitrack Clarity Redefined: Introducing our new Mic Bleed Remover

grh@auphonic.com (Georg) — Wed, 08 Oct 2025 05:30:35 +0000

You know that faint trace of your co-host’s voice leaking into your mic channel?

That’s mic bleed—and it’s why multitrack sessions can sound like one noisy room instead of one clean mix. Every mic hears everything: voices, ambience, reflections. The result is overlapping speech and unclear separation that’s hard to fix in post.

Our new Mic Bleed Remover tackles the problem at the session level: it analyzes all tracks together, learns what belongs to each microphone, and removes the unwanted cross-talk while preserving natural ambience and timing.

Try Mic Bleed Removal

What is mic bleed and why is it hard to remove?

Mic bleed happens whenever multiple microphones are used in the same space. Each one not only records its intended speaker, but also the others nearby. You’ll hear it in podcast interviews, roundtable discussions, or any setup where several people talk at once in the same room. Even with one mic per person, voices still spill into neighboring tracks.

Traditional tools like noise reduction or gates can’t really fix this: they’re designed to remove constant background noise, not speech. Gates simply mute parts of a track, often cutting off room tone and making conversations sound unnatural. That’s why mic bleed is one of the harder audio problems to solve cleanly.

From Crossgate to Continuous Improvement

We first tried to solve this years ago with our Crossgate – a smart gate that muted bleed when it detected it. It worked, but only in ideal conversations: one person talking at a time, clean room, no overlaps. Real-world recordings are messier. People interrupt. Tracks drift. Rooms echo.

We weren’t satisfied with our old model, so we decided to build something entirely new.

The new model: True Mic Bleed Removal

Our new Mic Bleed Removal model takes a completely different approach. It’s the first system that actually understands your session – not just mutes it.

Instead of processing each track in isolation, it listens to all tracks together and learns what belongs to each microphone. It then removes only the parts that came from other mics, keeping track noise, ambience, music and everything else intact.

This allows it to handle even difficult cases: overlapping speech, misaligned tracks, strong bleed, and background noise. The result is clean, separated voices that still sound natural, with all the original ambience and timing preserved.

The new model is fully deployed and available right now in all Auphonic Multitrack productions.

Hear the difference

The best way to understand Mic Bleed Remover is to listen.

How to use Mic Bleed Removal

Cleaning up multitrack recordings is now easier than ever. Just upload your multitrack session, enable Mic Bleed Removal, and let Auphonic do the rest.

Select Remove Mic Bleed Option in Master Audio Algorithms Section

The algorithm automatically analyzes all microphones together, identifies what belongs to each track, and removes unwanted cross-talk while keeping ambience and timing perfectly natural.

No complex setup. No manual gating. Just clear, separated voices straight out of the mix. To guarantee everything works for everyone, we’ve also put together a list of Multitrack Best Practices .

Conclusion

Mic bleed used to be one of those problems you just had to live with. Now, you don’t.
Upload your multitrack, switch on Mic Bleed Removal, and hear your session open up.

New Auphonic Static and Music Denoiser

lukasm@auphonic.com (Lukas) — Thu, 31 Jul 2025 09:43:32 +0000

Technology is evolving fast and we’re the ones pushing it forward.

Our new Static Denoiser removes steady background noise like hiss, hum, or fan noise while keeping music, ambience, and sound design fully intact. Perfect for audio dramas, videos, music, meditations, podcasts, or anything where clarity matters and the atmosphere does too.

Auphonic’s Vision for Noise Reduction

We firmly believe that there is no “one button to fix it all.”

But how can we say that when it is our mission to build exactly that?

Our goal is precision: Giving users full control over what stays and what goes.

That’s why we offer different tools for different kinds of noise:

Speech Isolation removes everything but your voice. It keeps only the speech you care about.
Dynamic Denoiser adapts in real time to changing environments - ideal for unpredictable noise patterns, while leaving music intact.
Static Denoiser now updated to precisely target stationary noise - like constant hiss or hum - while preserving music, ambient effects, and subtle details.

Think of audio dramas where sound effects should stay untouched, or meditation recordings with soft tonal elements that must remain intact. Unlike non-stationary noises (e.g. coughs, chair squeaks or mouth clicks), stationary noise is consistent over time - making it ideal for static removal without harming your content.

While we believe in precise user control, there is a way to reduce your audio editing work to almost one button: Saving your favorite settings as Custom Presets and applying those to your productions. You can even share your Presets with friends!
But more on that later 😉

How to Use the New Static Denoiser

Cleaning up your audio is easier than ever: Just upload your file, choose the Static Denoiser in the Production Form, and let Auphonic do the rest. No deep tech knowledge required.

Fine-tune the sound by adjusting the Remove Noise and Remove Reverb sliders. Lower them slightly to retain some natural texture while still boosting clarity and speech intelligibility.

And for everyone still wanting to use the Original Static Denoiser: Don't worry, the Legacy Denoising Version is still available. We renamed it to "Classic" and you can use it as normal. Just select it through the drop-down menu.

Audio Examples

It’s hard to read audio, but easy to hear the difference. Here is a sound comparison of our denoising models - please use headphones to hear all details!

New Static Denoiser vs. Speech Isolation

We processed a snippet from the History of Jazz podcast using both Speech Isolation and the new Static Denoiser. Speech Isolation removes everything but the speech - including music, background vocals, and ambience - resulting in a clean, voice-only track. In contrast, the Static Denoiser keeps the musical texture intact while removing just the steady background noise. Hear the difference for yourself!

New Static Denoiser vs. Dynamic Denoiser

In this excerpt from the German audio drama Der Graue, the “Static Denoiser” perfectly preserves all the sound effects while removing the reverb and static noise, whereas the “Dynamic Denoiser” (or “Speech Isolation”) removes everything from the audio that is not speech:

Original:
Static Denoised:
Dynamic Denoised:

New Static Denoiser vs. Legacy Classic Denoiser

To show how far we’ve come, we processed a short segment from the radio play Around the World in 80 Days using both the new Static Denoiser and the legacy Classic Denoiser.
The Classic Denoiser extracts noise prints in speech pauses, which is not possible in this example because of the background music, whereas the new model removes noise cleanly.

Original:
Old Classic Denoised:
New Static Denoised:

Try It Out

The new Static Denoiser is live! Perfect for cleaning up hiss and hum while keeping music and sound effects intact.

If you're used to the legacy model and want to keep using it: No worries, the Classic Denoiser is still available. Want more aggressive cleanup or even full music removal? Try our Dynamic Denoiser or Speech Isolation models .

Re-processing is free - so go wild:
As long as you don’t change your input file, you can tweak your production and test different settings without using extra credits. Try it. Break it. Compare models. Save your findings as your favorite preset. And please, tell us what you think!

New Automatic Cough Cutting

isabell@auphonic.com (Isabell) — Mon, 23 Jun 2025 13:07:02 +0000

Just in time for hay fever season, we are releasing a De-Cough feature that removes unwanted respiratory noises.
Our new “Cut Coughs” algorithm automatically cuts human noises like coughing, throat-clearing, sneezing and similar sounds, keeping your speech recordings clean, professional, and distraction-free — even when you or your guests are not feeling their best.
Check out our audio examples and hear how the audio gets healthier.

What Is New?

With the “Cut Coughs” feature, you can now decide if you want to remove respiratory noises like coughing, throat-clearing, sneezing, and other similar distractions from your audio.

Whether you are polishing your podcast, editing a webinar, or post-processing an interview, this option helps to create a smoother, more professional listening experience.
Of course, there are moments when you might choose to keep these human sounds — for example, in audio plays, medical lectures, video productions, or any projects where authenticity and unfiltered emotion add to the charm.

It is all about giving you control over how clean you want your audio to be.

Listen To The Speakers Acoustically Getting Healthier:

Mild Cold Symptoms

This record of a male speaker with a cold demonstrates how the audio sounds after processing with the new “Cut Coughs” option:

Original:
Coughs Cut:

As you can hear, breathing sounds are not removed, so we strongly recommend also activating the “Noise Reduction” algorithm, including the “Remove Breathings” option, to get a truly smooth and clean result:

Coughs Cut &
Denoised:

Heavy Coughing Attack

In this audio snippet extracted from the video “Late Night Coughing”, the “Cut Coughs” feature successfully removes a heavy coughing attack from the female speaker:

Original:
Coughs Cut & Denoised:

How To Use It?

To remove respiratory noises from your recording, simply activate the “Cut Coughs” option in the Automatic Cutting section:

If you want, you can also check, add and edit the cuts manually in our Auphonic Audio Inspector or export the provided Cut Lists for fine-tuning in your favorite audio/video editor.

Since the distinction between heavy breathing and mild cold symptoms is not always clear-cut, we recommend using the “Cut Coughs” algorithm together with at least the “Remove Breathings” denoising option.

The best setting for flawless speech — without any pauses or distracting sounds — is “Cut Coughs” in combination with “Cut Silence” and all three Noise Reduction options.
We set this up for you within the Auphonic Preset “Cut Filler Words, Coughs and Silence”:

Hear the results of this preset yourself in the “Coughs Cut & Denoised” file versions of our audio examples.

Share Your Experience — Be Part of the Improvement

New Auphonic Cut Editor - Blending Human Excellence with AI Automation

lukasm@auphonic.com (Lukas) — Thu, 22 May 2025 10:12:10 +0000

You can now manually set and edit cuts in your Auphonic productions!

We’ve extended the capabilities of our Automatic Cutting Feature by letting you choose which cuts shall be applied and fine-tune cut regions manually.
Let the machine do the editing work while you refine the results to achieve the exact output you’re listening for. All in one place!

How does it work?

Start using Auphonic as usual. For Quick Productions select the Preset “Cut Filler Words, Coughs and Silence“.
If you use the more advanced production page select Automatic Cutting then Cut Fillers, Cut Silence, Cut Coughs or all.
Start your production and let Auphonic work its audio magic. When the production is done you’ll reach the Results Page with the updated Audio Editing Interface:

Here you can manually refine all machine-made cuts and fine-tune your production to your liking. Adjust, activate, or deactivate existing cuts, or add new cuts yourself.

This, in combination with our Transcript Editor, lets you edit your entire production within Auphonic - eliminating the need to export and switch to a DAW.

New Interface & Workflow Example

You will see machine made cuts in the updated Audio Editing Interface.
We highlight the different cut-types (Fillerwords, Silence and User Cuts) in a specific color scheme:

You can deactivate cuts either through selecting a cut and clicking “Deactivate Cut” in the top bar or by using the hotkey [C].
For adding a user cut, set the playhead to the location you want to apply the cut to and click “Add Cut” in the top bar or use hotkey [C].

You can manually adjust the regions of all cuts using the arrow sliders at the edges of your selected cut. Allowing you to adjust machine made cuts and custom user cuts alike.
You’ll notice the waveform of the output audio turns white when you mark it with a cut region. Pre-listen to your cut result by setting the playhead before the cut and pressing play or spacebar [SPACE].
If you’d like to discard your changes and start over you can select “Reset All” and reset the production to what Auphonic delivered automatically.

When you’re done editing press “Apply Changes” at the bottom (or top) of the production page:

Auphonic will then reprocess your production and apply all the cuts and edits you made. You can also press “Edit Production” if you want to change feature settings. Your cuts will be saved and applied when you start the production with the updated settings.

Hint: Re-Processing will not burn additional credits!
All edits you make - including changes to presets and feature settings - are free of charge. So feel free to play around with all the tools we offer. Only if you change the input file(s) additional credits will be used.

What do you think?

We drive innovation through your feedback. Is there anything that would enhance your workflow? Do you have ideas for what this feature could look like in the next iteration? Or do you have ideas for additional features Auphonic should implement next?

Please, send us your thoughts HERE, or through the feedback form in your production!

We’re looking forward to your ideas and wish you happy editing!

Fillerword Cutting Optimized for Greek, Romanian and Hungarian

lukast@auphonic.com (Lukas) — Tue, 22 Apr 2025 06:04:05 +0000

Fillerword detection is highly language specific. While “uhm” and “aah” might be more common across the board, each language has its own unique fillerwords. We take this into account when improving our algorithms. Auphonic lets you automatically cut unwanted parts from your audio production, easily removing silence and fillerwords in multiple languages.

Introducing Greek, Romanian and Hungarian

We develop and train all of our algorithms in-house - and in our latest rollout, we've improved the detection of fillerwords in Greek, Romanian and Hungarian.

Fillerwords from these languages will now be detected more reliably and automatically removed from your productions.

To try it out for yourself, simply select “Cut Fillers” with our Automatic Cutting Feature either in the production page:

Feature Selection in the Production Page

Or you can select the Auphonic Preset "Cut Filler Words and Silence” in our Quick Production Screen on the landing page:

Auphonic Quick Production Presets

What do you think?

We drive innovation through your feedback and we would love to hear your thoughts! Do you have ideas for what this feature could evolve in the next iteration? Or suggestions for new features you'd like to see in Auphonic?

Please, send us your thoughts HERE, or through the feedback form in your production (as seen below)!

New Bandwidth Extension Feature with Enhanced Voice AutoEQ

mpagavino@auphonic.com (Manuel) — Fri, 04 Apr 2025 04:57:59 +0000

Ever struggled with muffled, low-quality audio in voice calls or old recordings? Our latest feature — Bandwidth Extension, now integrated with the Voice AutoEQ — is here to change that.
Audio bandwidth extension (BWE) intelligently restores missing high frequencies, making speech clearer and more natural, even in archival or low-bitrate recordings. Listen to our BWE audio examples below to hear the difference for yourself!

What is Audio Bandwidth Extension (BWE)?

Audio bandwidth extension is a technique used to artificially recreate or “extend” higher audio frequencies that may have been lost or limited during recording, transmission, or compression. By analyzing the existing frequency information in an audio signal, our algorithm can predict and synthesize additional higher-frequency components. This approach helps restore the brightness and clarity of an audio track, making it sound more natural and pleasant to listeners.

Bandwidth extension is particularly helpful in scenarios such as working with archival speech recordings, low-bitrate voice calls, and compressed audio streams where high frequencies are lost due to bandwidth constraints.
The Auphonic bandwidth extension is specifically optimized for speech and does not enhance music or environmental sounds, like noise, reverb, etc.

Listening Examples

The following example from the Lex Fridman Podcast #457 demonstrates how it is possible to take a high-quality recording, downsample it to 4 kHz bandwidth, and then use our bandwidth extension algorithm. The result comes remarkably close to the original audio with a full 20 kHz bandwidth.
Hear the difference yourself as the audio regains its natural clarity and depth:


Original Audio:

Low Bandwidth:

Bandwidth Extended:

Bandwidth extension of historic recordings (male and female speaker)

In practice, bandwidth extension is useful for restoring historic recordings that have been downsampled due to bandwidth constraints. This example is a record of the historic “Margaret Thatcher's Iron Lady speech” and shows the difference between the original recording and the bandwidth-extended version:

Low Bandwidth:
Bandwidth Extended:
BWE and Denoise:

We added a version with and without denoising here, to hear that our algorithm does not add frequencies to environmental sounds like noise, reverb, etc.

The second example is an archive recording of Richard Nixon's “End Of Vietnam War speech”:

Low Bandwidth:
Bandwidth Extended:
BWE and Denoise:

How to use it?

To activate the new bandwidth extension feature, just select the option “Voice AutoEQ + Bandwidth extension” as “Filtering Method” in the section “Filtering”:

Or use the Auphonic preset “Bandwidth Extension and Voice AutoEQ (keep noise)”:

Bandwidth extension is always applied in combination with the Voice AutoEQ, where we also released some updates ...

Voice AutoEQ Updates

We took some time to further refine our Voice AutoEQ algorithm, please also take a look at our previous blog post.
Now the Voice AutoEQ works more effectively with reverberant speech and can adapt even when speech is mixed with background music.
The de-plosive/de-pop feature that reduces strong plosives in speech is now integrated into our Noise Reduction Algorithm making Voice AutoEQ even more effective when combined with our Speech Isolation or Dynamic Denoiser.

Voice AutoEQ Listening Examples

Voice AutoEQ with background music

This is an example from the Climate Of Joy podcast intro. The enhanced version improves speech intelligibility without affecting the music balance.

Original:
AutoEQed:

Voice AutoEQ with reverberant speech

This recording by conduitministries.com is recorded in a very reverberant room. The original audio sounds slightly dull, but the Voice AutoEQ version preserves the reverberation while adding more clarity. However, if you want to decrease the reverb, you could also select the Remove Reverb amount option in our Noise Reduction section.

Original:
AutoEQed:

Reducing plosives in speech

This snippet extracted from a video about Pop Filter vs Windscreen shows how our Noise Reduction algorithm — here in combination with the Voice AutoEQ — can be used to reduce plosives in speech.
(Please listen with headphones or good loudspeakers to hear the difference.)

Introducing Auphonic Team Accounts

manuelw@auphonic.com (Manuel) — Wed, 14 Aug 2024 09:11:04 +0000

The new Auphonic team accounts streamline billing for companies, teams, or groups and are available to business users. A team account's owner can invite team members and admins, all of whom share the team account's credits for their productions.

The team account feature only impacts billing. Team members cannot access each other’s productions, presets, etc.
If you're interested in switching to a team account, please contact us!

What are Auphonic Teams?

A team consists of an Owner with Members and optional Admins. The Owner and Admins can add and remove team members as well as change their roles in the team. Every added account can use Auphonic as usual, but only the account Owner's credits are used for billing productions.

This simplifies the invoicing process for teams using multiple Auphonic accounts.
One Owner provides the credits, and all of the team can use them.

Overview of the team accounts section in the account settings.

Inviting Users

After gaining access to the team account feature, you can invite new team members via the team account section on the account settings page. Invited team members can be:

Existing Auphonic users
New users who do not yet have an account

When inviting users, you can assign them a role: Member or Admin. Sent invitations can be cancelled at any time.

Managing Team Account Members

The team account Owner and Admins can remove members and change roles within the team.

Editing roles

Roles and Permissions

Within the team, there are three roles: Owner, Admin and Member. Each role has specific permissions:

All roles and permissions.

Note, that the Owner role - held by the account creator - cannot be changed manually.
Please contact us if you want to change the owner of a team account!

Billing

The Owner of the team account is responsible for purchasing credits. Productions made by team members will use the team account's credits. As a team account member, you will see the team account owner's credit balance instead of your own.

If you wish to access your personal credits, you can leave the team at any time.

Conclusion

With the introduction of team accounts, we provide a solution to simplify the production process for teams. One account is responsible for providing the credits and all team members can use them collectively!

Feedback

We are always happy to receive feedback on our features!

Speaker Identification in Single Track Productions

lukast@auphonic.com (Lukas) — Mon, 05 Aug 2024 09:34:04 +0000

We're excited to announce the release of our new speaker diarization feature! With our latest update, we can now detect individual speakers within a single audio recording, allowing users to see precisely who said what and when. This information is then reflected in the transcript.
Previously, this feature was only available in Multitrack Productions.

What is Speaker Diarization?

Speaker diarization is the process of identifying different speakers and segmenting an audio file accordingly, making it easier to accurately determine who said what. This is particularly useful in scenarios like meeting recordings, interviews, and podcasts involving multiple speakers.

What's New

Until now, Auphonic users had to use our Multitrack Production Workflow to gain access to speaker identification. With our recent update, this feature is now also accessible for single track productions, thereby further simplifying our workflow.

How It Works

When selecting Auphonic Whisper ASR as your speech recognition engine on our production page, the option to use “Speaker Detection” appears. You can select the number of speakers in the recording yourself, or have the AI identify and label them automatically.

Select "speaker detection" in the speech recognition menu

The identified speakers will then be shown next to what they said in the captions of our audio player and within the generated transcript. We know exactly who is saying what at any given time.

If you need to change speakers' names, you can edit them in our Transcript Editor. By changing the name of the speaker, the changes will be applied automatically within the whole transcript.

Click here for an example transcript to play around with!

The transcript editor also lets you edit the generated transcript's content and correct any mistakes. This gives our users the final say in quality control.

For more information on how to use our transcript editor, click here!

Conclusion

With our newly released speaker detection feature for single track productions, we simplified the automatic transcription process even further. You can drop a single audio file into our algorithms, the AI automatically detects and transcribes its contents and attributes speakers correctly. And if the model should unexpectedly be wrong at any time, you can correct it in our Transcript Editor.

Feedback

We're looking forward to having you utilize our new speaker diarization feature!
Please, feel free to send us feedback through our Contact Form or submit it directly in the status page of your production.
Happy detecting!

Support for Intro and Outro Videos

lukasm@auphonic.com (Lukas) — Wed, 03 Jul 2024 12:03:17 +0000

A new foray into the world of video: Auphonic is proud to announce support for intro and outro videos! With our most recent update you can now seamlessly integrate video intros and outros into your productions, providing a richer and more engaging experience for your audience.

What's new?

For a long time Auphonic has supported video files as the main files of productions. Until recently, intros and outros were limited to audio-only though.

Our new feature now allows you to add video intros and outros to your productions. This means your content can now begin and end with video clips, adding a professional touch and increasing viewer engagement. Whether you're working on podcasts, audiobooks, or any other type of multimedia content: providing your content both in audio form and in video form is now way easier!

Mixing Audio and Video

A key aspect of this feature is the ability to mix audio and video files effortlessly. If your main production file is a video but your intro is an audio file, Auphonic will automatically generate a video for the intro using a standing image from the main video. This ensures a seamless and visually coherent transition between different media types, maintaining the overall quality and flow of your production.

It works the same way for outros as well. When your main production file is a video file but your outro is audio-only we will generate an outro video from a standing image of the main video.

Overlap

We also support overlap for video intros and outros. This means you can have your intros and outros start or end slightly before the main content, creating a smoother transition. However, you should know that overlapping intro and outro videos requires us to place a cut in your video intro and outro. Only this way the the audio will stay in sync with the video.

How to add Intro and Outro Videos

Using our new feature is incredibly simple. You can add video intros and outros the same way you would add audio intros and outros in the production form.

A screenshot of the production form where a video intro and a video outro where selected.

Adding video intros and outros is also available through our API, allowing for a smooth integration into your existing workflows and automation processes. Again, adding video intros and outros in the API works the same way it works for audio intros and outros.

Use Cases

There are many different use cases for our new feature! If you, as an example, regularly release episodes of your podcast both as audio and as video, you can now automatically add a recurring video intro and outro without needing to manually edit your videos.

Or, if you're an audio engineer, you may have a large number of recordings of, let's say, a conference. Instead of having to edit each individual conference recording by hand you now can add a common intro and outro to each conference recording automatically using a batch production.

Supported Video Formats

The world of video is a limitless one, with a sheer endless amount of video codecs, resolutions or frame rates to offer. Naturally, this means we are not able to support every arbitrary video format there is. However, we made sure to support the most commonly used video containers and codecs to make sure that at least 99.5% of all video productions will be possible.

Currently we support the 3 most common video containers: MP4, MKV and MOV. For these containers the following codecs are supported:

h264: MP4, MKV, MOV
mpeg4: MP4, MKV, MOV
mpeg2video: MP4, MKV, MOV
prores: Only MKV and MOV
msmpeg4v3: Only MKV and MOV

Any video intro or outro which uses these containers and codecs can be processed by us. Additionally, we make sure that your output video uses a common format. Therefore, if your video intro or outro uses a different codec or container than your main video we will encode the video intro or outro to the setting of the main video.

Given that video demands significantly more computational ressources than audio the video intros and outros may be 1 minute long at max in order to be processed.

Conclusion

The new intro and outro videos feature on Auphonic is designed to give you more creative control and to help you produce professional, engaging content effortlessly. By supporting a variety of codecs and allowing for the mixing of audio and video we aim to support every possible workflow. We invite you to explore this new feature and see how it can enhance your multimedia productions!
