Comment (by j7n):
What is wrong in CC 2017? I notice that the top bands are sightly lower
level, and the dithering doesn't have a spike on every block of 256
samples.
Where is the fault with these two tracks not being gapless in MP4? They
have an overlap of 2 frames (3072 samples). In "edts"/"elst" track 05 has
a recorded delay of 2688 samples, which are discarded by ffmpeg from the
start. To achieve gaplessness, 384 more samples should be deleted, which
doesn't happen. Track 04 has a duration of 0x38FE80 - delay of 0x0800 =
0x38F680. The actual decoded duration is decimal 3733504 (384 longer). I
can open another issue if it is warranted.
