  • Turning a recorded meeting into an audio file for transcription
  • Saving audio from a video interview for editing

FAQ

MP4, WebM, MOV, and AVI are supported. Actual playback and extraction depend on your browser's codec support.
Audio is extracted as a WAV file for maximum compatibility. You can then convert it to MP3 or other formats with the Audio Converter.
Copying the stream directly into a new container is lossless. Re-encoding into a different format does cost some quality, so pick a format that matches the source where you can.
At best, the bitrate of the audio inside the video — often 128 kbps or lower for web video. Asking for more produces a larger file with no additional quality.
MP3 for listening and sharing, WAV if the audio is going into an editor, M4A if the source is already AAC and you want a clean copy.
The whole file has to be read through to separate the streams, so duration and file size both matter. A long, high-resolution video takes a while even though only the audio is being kept.

About Video to Audio

A video file is a container holding separate video and audio streams. Extraction pulls the audio stream out, which is why it is fast — usually far faster than any operation that has to re-encode the video.

Where possible, copying the audio stream directly is lossless: the original encoded audio is written into a new container without being decoded and re-encoded. Re-encoding to a different format does cost quality, so if the source audio is already AAC and you extract to M4A, you may get a perfect copy, whereas converting it to MP3 will not be.

Audio quality is capped by the source. Video platforms compress audio hard, often to 128 kbps or below, and extraction cannot recover what was never there. Requesting a 320 kbps MP3 from a 128 kbps source produces a bigger file containing the same audio.

Tips and limits

  • Extracted audio can only be as good as the audio in the video.
  • Requesting a higher bitrate than the source has just inflates the file size.
  • Use WAV if you plan to edit; MP3 if you just want to listen.
  • Long videos take a while — extraction is fast per minute but there are a lot of minutes.
  • Some videos carry multiple audio tracks; check you extracted the one you wanted.
