Comment (by ego-lay_atman-bay):

 The difference is that in the ffmpeg result, there is a lot of static,
 whereas the musepack tools (mpcdec) (expected) output doesn't have all
 that static.

 This shouldn't be an issue with the wav files, but just in case, I'm using
 vlc, audacity, and pretty much any other audio player I use.

 The issue is with the mpc decoding, since vlc has the same issue while
 playing the mpc file. However I have found that foobar2000 doesn't have
 all the static (it does with the ffmpeg wav result).

 If you compare both wav files in audacity, you'll see they are pretty
 different, and the ffmpeg result has way more static.

 The ffmpeg mp3 playback sounds the exact same as the wav result (at least
 in vlc for android).
