Found an m4a file on one of my old hard disks. Sure enough, Audacity
wouldn't import it, even though it tried to use ffmpeg. But vlc and
mplayer played it fine. The quickest thing to do is one of these two
mplayer -vo null -ao pcm:fast:file=file.wav file.m4a
or even simpler,
ffmpeg -i file.m4a file.wav
If you're not comfortable with command line stuff, install vlc, run it,
open the m4a file, verify it plays as you expect, and then File ->
Convert/Save and convert it to a WAV file there (select WAV for both
encapsulation and codec).
The resulting file in all three cases opened fine in Audacity.
