Comment (by calestyo):

 I found a set of test vector AAC files, that are ought to play back
 gapless (by using meta data according to MPEG standards,.. not the iTunes
 stuff which - of course (Apple) - does it different):
 https://www2.iis.fraunhofer.de/AAC/gapless.html

 (turn down your volume as these files have a pretty loud and annoying
 sound, IMO)

 When decoding these files with FFMPEG to e.g. WAV, there is a "gap" added
 at the end (just as described in the website above)... interestingly,...
 AFAIU the website, decoders "not doing it right" would also add a "gap" at
 the beginning, but it seems this works properly with ffmpeg (but maybe I'm
 doing something wrong here).
