Audio Extractor from Video API

What it does

Video Audio Extractor pulls audio from a video source and returns it as a downloadable file or a signed cloud link. Send either a video_url or an uploaded video, then choose whether you want the full audio track or just a segment.

Use start_time to set the seek offset, duration to control how many seconds to extract, and output_format to choose the format: mp3, wav, aac, ogg, flac, wma, or ac3. When full_audio is enabled, the service ignores duration and extracts the complete track.

The service exposes URL-based and multipart upload workflows, so you can handle both remote media and local files. For URL requests, you can download the binary output directly or receive a time-limited signed URL in data. For uploaded videos, the same output options are available.

Use Video Audio Extractor when you need to isolate narration from a training clip, pull a soundtrack from a user-uploaded video, or generate an audio asset for downstream processing in your pipeline.
