Extracting just the audio from big video files

29 July 2017

Got a big video, and want a copy of just the audio for listening on a device with limited storage? Use Soundconverter.

soundconverter -b -m mp3 -s .mp3 long-video.webm

(MP3 patents are expired now, hooray! I'm just using MP3 here because if I get a rental car that lets me plug in a USB stick for listening, the MP3 format is most likely to be supported.)

Soundconverter has a GUI but you can use -b for batch mode from the shell. soundconverter --help for help. You do need to set both the MIME type, with -m, and the file suffix, with -s.
