Extract audio from a video
Pull the audio track out of a video when you need a podcast clip, a voiceover, or a song from a screen recording. Video frames are discarded, and the audio is encoded as MP3.
Run this tool
Files stay under 20 MB. Successful encodes use compute seconds. Failures are not billed.
How it works
- 01Upload a video that contains an audio track.
- 02Pick an MP3 bitrate. 192 kbps is a solid default for voice and music.
- 03FFmpeg drops the picture and encodes the audio as MP3.
- 04Download the MP3. Only a successful extract is billed.
Limits
- Each file can be up to 20 MB. Successful runs count against your monthly compute seconds and request quota. Failed encodes are not billed.
- The source needs an audio track. A silent video fails, and that failure is not billed.
- Output is MP3. Bitrate can be set from 64 to 320 kbps.
FAQ
Will this work on a screen recording?
Yes, when the recording includes audio. System-audio-only and camera-audio files both work, as long as FFmpeg can find an audio stream.
Does extracting audio use fewer compute seconds than re-encoding video?
Usually, yes. The job does not encode video frames. You still pay for the wall-clock time the encoder runs, with a minimum of one second on success.
Can I get a WAV instead?
This tool outputs MP3. For another format, send the file through the API and set the FFmpeg args yourself.
Related tools
Mute a video
Remove the audio track from a video and download a silent MP4. Sign in to run it. Successful mutes use your FFmpeGo compute seconds; failures are free.
Convert a video to MP4
Convert WebM, MOV, MKV, and other videos to an H.264 MP4 that plays in browsers and editors. Sign in to run it — successful converts use your FFmpeGo compute seconds.
Compress a video
Make a smaller MP4 from a video by re-encoding it with H.264. Raise the CRF for a smaller file, or lower it to keep more detail. Sign in to run it on your FFmpeGo quota.
Need this in your app?
The same encode is available as POST /v2/run. Send the inputs and FFmpeg args from your own code, and pay only for successful compute seconds.
