I do this all the time on Linux. Haven't tried it on my Mac, but I expect something similar should be possible.
I use this command with either mkv or webm files without issues. ffmpeg -i [filename.mkv|webm] -acodec pcm_s16le -ac 2 audio.wav The above requires you've installed the ffmpeg libraries. It produces just the audio in the file called audio.wav. You can do whatever with that file, of course, rename it, flac it, or encode it into an mp3, etc., etc. I should note I have this command in a shell script where [filename.mkv|webm] is "$1" and I simply use the filename I'm extracting the audio out of as the only argument to the script command.
