Comment (by Guy Sivey):

 Sorry, I don't know what you mean. I am providing this information for
 your benefit, in case you might want to improve ffmpeg. The history which
 leads me to think that there is a problem with ffmpeg is as follows:-

 - The uploaded m4a/aac files are made with iTunes on a Windows PC, from
 edited WAV files.
 - These m4a/aac files play continuously with no gap when played with
 foobar2000 on a Windows PC, but there is an audible gap when they are
 played with mpd on a Raspberry Pi with Raspbian.
 - I referred this to the developer of mpd, who claims that, using the
 commands shown, he proved that the problem is with ffmpeg. He did not
 indicate which version of ffmpeg he used.

 So I have referred his findings to ffmpeg for further investigation. Since
 I have discontinued use of mpd, it is of limited interest to me whether
 you follow this up or not. I just thought it might help if I reported it.
