Common questions

Why is audio extraction so fast?

The video processing engine discards the video stream (`-vn`) and only processes the sound packets, taking just a fraction of the time required to re-encode video.

Which format should I choose?

MP3 is compatible with almost every player and phone. Choose WAV if you plan to edit the audio track in software like Audacity or GarageBand.
