Comment (by Balling):

 Intersting, but simply first decoding aac to wav (be it 24 bit or 16 bit,
 or whatever) allows one to produce

 Input True Peak:      +0.0 dBTP

 and not (I also get that when I decode using aac):

 Input True Peak:      +0.1 dBTP

 That happens because

 ffmpeg -c:a aac_fixed -i palestine-song192k.mp4 -c:a pcm_s24le -af
 ebur128,loudnorm=print_format=summary -f null -


 (aac_fixed) is not the default, LOLZ.

 There is also an issue that AAC is not gapless in the end, but that should
 not matter much. But will check gapless stuff.
