# Fix distorted and clipped audio: online AI declipper

Rebuild peaking, flat-topped, and blown-out voice recordings without harsh digital crunch.

Powered by [Audio enhancer](https://audo.ai/audio-enhancer.md) — tuned to reconstruct clipped vocal waveforms.

## How it works

1. Upload the distorted voice recording or video clip where speech peaks in the red.
2. Leave Declipping strength at Full rebuild for heavy overload, or dial toward Light repair for brief plosive ticks.
3. Check the smoothed waveform in the player, then download your repaired file.

## Overloaded voice recordings an AI declipper rescues

When hot preamps or unexpected shouts chop waveform crests flat above 0 dBFS, rebuilding vocal harmonics removes the buzz that volume faders leave behind.

### Podcasts & loud reactions: Fix peaking audio on sudden laughs and animated guests

Even when calm conversation sits safely around −12 dB, a sudden burst of laughter or an excited shout slams the USB interface into 0 dBFS redline. Upload the episode to fix peaking audio so loud reactions play back smooth and clean beside quieter turns.

### Weddings & mixer feeds: Fix clipped audio from hot DJ boards and ceremony mics

Feeding a DJ console's hot +4 dBu line output into a camera or portable recorder switched to mic level bricks an entire wedding toast into squared-off fuzz. When re-recording the vows or speeches is out of the question, you can fix clipped audio directly on the WAV or MP4 file.

### Streams & close mics: Remove distortion from audio in gaming clips and commentary

Hyped callouts and lips pressed right against a headset boom overload the microphone capsule before software limiters in OBS ever catch the peak, leaving crunchy breakup below 0 dBFS. Rebuilding vocal harmonics cleans analog capsule saturation as well as digital brickwalling.

### Beyond Audacity Clip Fix: Audio declipper for sustained overload where interpolation fails

Cubic-spline filters such as Audacity Clip Fix bridge 2 or 3 consecutive clipped samples, yet fall apart when dozens of samples flat-top in a row. Inspect exact Clipped samples and true peak (dBTP) in LUFS meter first, then run our generative declipper on heavily overloaded takes.

## Why turning volume down leaves crunch — and how declipping rebuilds peaks

Powered by Audo's Audio enhancer, this online audio declipper repairs clipped speech in audio (WAV, MP3, M4A, AAC, FLAC, OGG, Opus, WebM, AIFF) and video (MP4, MOV, MKV, WebM, AVI) recordings up to 10 GB without signing in (up to 10 hours signed in), offering the first minute of each file free, 3 times a day, with no sign-up. Runs finish in about 8 seconds for 1 minute, about 38 seconds for 20 minutes, and under 2 minutes (about 1 minute 42 seconds for audio) for an hour-long file.

When a microphone preamp or analog-to-digital converter overloads past 0 dBFS, the rounded tops and bottoms of the sound wave are sliced flat into hard corners, splattering harsh odd-order harmonics across the voice. Pulling clip gain down −6 dB in a video editor only produces a quieter square wave, and traditional interpolation declippers like Audacity Clip Fix need clean slopes on both sides of a tiny 2-to-3-sample clip — failing both on sustained brickwalling and on mixer feeds attenuated after clipping upstream. Audo resynthesizes clean, rounded 48 kHz vocal harmonics and sets loudness to −16 LUFS below −1 dBTP so repaired dialogue never re-peaks.

Keep Declipping strength at Full rebuild for blown-out takes, or move toward Light repair when only occasional loud consonants clipped so calm sentences retain their raw mic tone. Distinguish voice overload from hardware noise: continuous buzz or 50/60 Hz hum during silent pauses comes from cables or power and belongs in Remove static, dropped USB buffers with silent gaps can be tightened in Cut audio, and distorted guitars or clipped concert music cannot be repaired here because music is removed (use Vocal remover for songs, or check true peak first in LUFS meter).

Identifying whether distortion is vocal clipping, cable buzz, or dropouts

| What you hear in the file | Underlying cause | Best tool or setting |
|---|---|---|
| Harsh crunch and fuzz on loud vowels, shouts, and laughs | Converter hit 0 dBFS and sliced waveform crests flat | Declipping strength at 85–100% (Full rebuild) |
| Distorted voice even though peaks stay around −6 dB | Upstream DJ mixer, wireless receiver, or mic capsule overloaded before attenuation | Declipping strength at 100% (catches sub-0 dB analog breakup) |
| Occasional tick on loud plosives in a clean studio take | Brief 1–3 sample transient overshoot | Declipping strength at 40–60% (Light repair) to preserve raw tone |
| Steady electrical buzz, hum, or crackle during silent pauses | Loose 3.5 mm plug, ground loop, or dimmer interference | Remove static (clears steady buzz while keeping unclipped speech intact) |
| Words cut out completely into brief 50–200 ms silent holes | USB buffer underruns or wireless packet dropouts | Missing syllables cannot be reconstructed; trim around gaps in Cut audio |

## Free API

```bash
curl -F file=@wedding-toast.mp4 https://audo.ai/api/try/enhance-voice -D response.headers -o response.body
```

Read response.headers and response.body before naming media. Handle 202, 200 JSON and errors with the complete response client at https://audo.ai/docs/api?utm_source=markdown&utm_medium=agent#responses.

Free for the first minute of each file, 3 times a day per person, with no key or account. Uploads up to 10 GB, 2 at once from one address. The response is the result itself; a job that runs longer than about 30 seconds returns 202 with a link to check on it. With an API key (`-H "Authorization: Bearer $AUDO_API_KEY"`), omitting free runs the full job with credits if the balance covers it, otherwise the free allowance if quota remains. Set free=true to prohibit spending; for paid runs use free=false with an approved positive max_credits. A free result cut short comes with finishUrl (and the Audo-Finish-Url header when the response is the file itself): give it to the person, who pays there (from $5, no sign-up), and the whole file runs; keep checking the status link, whose finishedBy names the whole-file job and its own status link.

## Options

Form fields with the same names as the MCP tool's inputs:

- `noise_reduction`: How much of the regenerated voice to use, as a percentage. 100 uses all of it; lower values mix back some of the original sound. Default 100.
- `auto_volume`: Sets the whole file to -16 LUFS with one gain, and limits peaks to -1 dBTP. It doesn't balance loud and quiet speakers. Default true.
- `output_format`: The result's format: same (as the input; a video stays a video), wav, mp3, m4a, or flac. Default same.

## Languages

Any language: it works on the sound, not the words.

## From an assistant (MCP)

Add https://audo.ai/mcp and sign in (setup for each assistant: https://audo.ai/setup.md). The tool is `enhance_voice`:

> Regenerates speech: removes echo, noise, and distortion, and restores muffled, phone, or low-quality voices. Then sets the file to -16 LUFS. Made for voices: music and other sounds are removed too. Works on video. Use it for echoey, phone, low-quality, or damaged recordings. Not for plain background noise when the voice is fine (remove_noise keeps the real voice). It costs 5 credits a minute, charged only if the job succeeds. Returns the result with download links, or job_id for get_job if it takes longer.

Example: "Use Audo to fix the clipped, peaking speech in wedding-toast.mp4."

## Questions

**Is there a free audio declipper to fix distorted audio online?** Yes. Audo repairs clipped and peaking speech for free on the first minute of each audio or video file, 3 times a day, with no sign-up. Whole files run at $0.05 a minute ($3.00 an hour), paid once as needed with no subscription — see pricing.

**How do I fix clipped audio and audio peaking after recording?** Add the overloaded audio or video file to Audo above, choose Declipping strength, and download the rebuilt version. Audo replaces squared-off harmonic crunch with clean 48 kHz vocal crests and normalizes loudness to −16 LUFS under a −1 dBTP ceiling so peaks stay out of the red.

**Why didn't Audacity Clip Fix or lowering clip gain remove the distortion?** Lowering volume in an editor scales down the flat-topped waveform without restoring the sliced-off wave crest, so the harsh buzz stays audible at every volume. Audacity Clip Fix estimates missing peaks with cubic splines across a few clipped samples, which breaks down on heavy brickwall clipping or when an analog mixer clipped below 0 dBFS, whereas Audo's Fix distorted audio reconstructs clean vocal harmonics across sustained overload — see our Audacity noise and repair guide.

**How can I check Clipped samples and true peak (dBTP) before and after?** Drop your recording into Audo's LUFS meter or Media info, both of which analyze whole files for free with no sign-up. The report counts exact clipped samples and shows inter-sample true peak in dBTP alongside integrated loudness.

**Is crackling from a loose mic cable the same as peaking distortion?** They behave differently. Peaking distortion happens when loud words exceed headroom, flattening the voice itself — which Audo's Fix distorted audio rebuilds. A loose TRS jack, ground loop, or power adapter creates buzz and crackle even while nobody is talking; for steady line buzz on an unclipped voice, run Audo's Remove static instead.

**Can this declipper fix blown-out bass, clipped drums, or concert music?** No. Because Audo's audio declipper reconstructs human speech, musical instruments, bass drops, and singing are stripped out rather than repaired. If background music is mixed behind spoken dialogue in a video, separate the soundtrack first with Remove music from video.

**Can ChatGPT or Claude repair clipped recordings with Audo?** Yes. Once Audo's MCP server is connected, you can hand a clipped interview or video clip to ChatGPT, Claude, or Cursor and ask it to declip the speech. Add Audo to your assistant once to use it across chats.
