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.

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.

Yes. Send MP4, MOV, or WebM and you get the edited video back — no need to extract and re-attach the audio track yourself.

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.

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.

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. Startups can request up to 200 hours of free API credit from the API Keys page in the app.
