Comment:

 Looking into Beyond Compare there is quite a big differnce between thd and
 mlp files encoded from
  7s-sinetone-sample.wav but there is almost no difference between THD and
 MLP encoded from 10s-sine.wav. That is the bug I imagine and yes THD file
 decoded by PLEX encoded by ffmpeg from 7s-sinetone-sample.wav is very
 different in the end.


 It looks like MLP and THD encoders are almost the same with some flags
 differences only. Very strange.
