Which should I pick, MP3 or WAV?

MP3 for listening, sending or archiving speech. WAV when the audio is raw material for something else and you want no further loss.

How much smaller is the result?

Typically a tenth to a twentieth of the video for MP3, since the picture is the overwhelming majority of a video file.

Can I extract from several videos at once?

Yes. Add them all and each produces its own audio file, named after its source.

It says my video has no sound. Why?

Some recordings genuinely have no audio track — screen captures made without audio permission are the usual culprit. There is nothing to extract in that case.

About the Video to MP3

Pulling the sound out of a video is one of those tasks that appears simple and is usually surrounded by advertising, sign-ups and a queue on somebody else's server. It is not a complicated operation. The audio is already there as a separate track inside the file; the job is to lift it out and write it into a container that holds sound alone.

The reasons people need it are consistent. A recorded lecture, meeting or interview that only needs to be listened to, and takes a tenth of the space without the picture. A talk to put on a phone for a commute. A piece of dialogue destined for a transcription tool that wants audio. A soundtrack extracted from one clip to lay under another.

MP3 leads here because practically every device ever built will play one, car stereos and equipment predating streaming included. WAV is the alternative and it throws nothing away: the samples are written out uncompressed, at roughly ten times the size, which is exactly what you want when the audio is going into an editor for further work and exactly what you do not want when you are emailing it to somebody.

A note on quality that applies to any tool of this kind. The audio inside a video was already compressed once when the video was made. Writing it out as MP3 compresses it again, and a second pass always costs a little. For speech this is inaudible at a sensible setting. For music you intend to keep, choose WAV and accept the size — the extra loss is not worth the saving.

If your file has no sound track at all, that is reported plainly rather than handing you an empty file.
