Audio Extractor from Video API

Hosted on ApyHub

What it does

The Extract Audio from Video API pulls the audio track out of a video. Upload a video (MP4, MKV, AVI, MOV, FLV, 3GP, or WebM, up to 100 MB) or send the URL of a video file, and get the audio back as a file or as a signed download link, in MP3, WAV, AAC, OGG, FLAC, WMA, or AC3.

Set full_audio to true to extract the whole soundtrack. Without it, the API returns a 2-second clip, which you can move and resize with start_time and duration.

Use it to prepare recordings for transcription with the Speech to Text API, turn video content into podcasts or audio clips, or process the audio from uploaded videos separately. The URL must point to a video file you have the right to use; links to pages on sites like YouTube aren't supported.

For long videos, use the Extract Audio from Video Job API, which processes them in the background.

You can start on ApyHub's free tier with no card required.
