Extract Audio from Video API

About Extract Audio from Video API

The Video Audio Extractor API takes a video source, either a URL or an uploaded file, and submits an asynchronous job to extract its audio track. Submitting to the URL-based endpoint or the file-upload endpoint returns a job_id, which is then polled via a status endpoint until the extraction completes and returns a link to the output audio file.

The extraction window is configurable through start_time, duration, and full_audio parameters: by default the service extracts a 2-second clip, but full_audio can be set to extract from start_time through to the end of the file. Output can be produced in mp3, wav, aac, ogg, flac, wma, or ac3 format, with mp3 as the default. Pending and failed jobs return a human-readable status message. File uploads are capped at 100MB per request.

The API is suited for pulling a soundtrack from a video clip, converting video assets into audio for downstream processing, or generating short audio samples from larger files for review and testing, as part of automated media workflows. It is hosted on ApyHub and consists of three endpoints: two submission endpoints (POST) and one job-status endpoint (GET), with a recommended polling interval of at most once per second.
