How it works

01

Get your API key

Create an account for free. Copy your API key from the Developers dashboard.

02

Install the SDK

Use the official Python or JavaScript SDK. Or you can call the REST API directly.

03

Upload your file

Use a local file or the URL of audio/video that you want to edit.

04

Auto-Poll or Webhook

Jobs run async. SDK handles polling automatically. Or use our webhook to upload the result to your s3 storage.

Frequently askedQuestions.

Ask Now
What is the difference between the breath modes?
breath: true is full removal — the best default, built for general and challenging recordings. "legacy" is conservative removal that plays it safe on already-clean studio takes. "natural" lightens breaths instead of deleting every one, so the speech keeps its human rhythm. You can switch modes per request, so different shows or clients can get different treatments from the same pipeline.
Can I remove breaths without changing the timing?
Yes. Set muted: true and Cleanvoice silences the breaths instead of cutting them out. The file keeps its exact original length, which matters when the audio has to stay in sync with video, slides, or a separate music bed.
Does it work on video files?
Yes. Send MP4, MOV, or WebM and you get the edited video back — no need to extract and re-attach the audio track yourself.
Can I clean up more than breaths in the same request?
Yes — breath removal is one flag in the edit config. In the same API call you can also enable fillers, mouth_sounds, long_silences, stutters, remove_noise, studio_sound, and normalize. One upload, one result file.
How is this different from a DeBreath plugin?
Plugins like Waves DeBreath or iZotope RX run inside a DAW and need someone to open each file, tune thresholds, and listen through. The API is for pipelines: your code submits files, Cleanvoice detects and removes the breaths automatically, and a webhook tells you when each one is done. It scales from one file to thousands without an engineer in the loop.
How do I try it — is there a free tier?
Sign-up comes with free credits, so you can run real files before paying anything. After that it is pay-as-you-go or a subscription, billed by audio length. Early-stage startups can apply for up to 200 hours of free API credits.
