Audio Denoiser reduces background noise in an uploaded audio file and returns the cleaned audio as a binary file. Send a file and, if needed, set strengthDb to control how aggressively noise is removed.
Use it when you need to improve voice recordings, customer support clips, interview audio, or other speech-first content before transcription, review, or publishing. The input schema accepts one file field in the request body, with files up to 30 MB, plus an optional strengthDb value.
The response is the processed audio file itself, so you can store it, pass it to another workflow, or hand it off to a downstream transcription step without extra parsing. Keep it in your media pipeline when you need a simple, deterministic denoise step for user-uploaded audio.
Upload an audio file to denoise it.
