Comment (by Balling):

 >The uploaded m4a/aac files are made with iTunes on a Windows PC,

 Ffmpeg does not support iTunSMPB, seamless playback, that Itunes uses,
 even for mp3 sound (at least here patches are on mailing list)!!

 Only the new way with editlists and those only work in mp4 AND also AFAIK
 at least for EAC3 there is no removal of trailing samples...

 iTunSMPB will remove those too.
