Comment (by Kamedo2):
After applying the new LPF at comment:70, the result bitrate of music
changed a bit. I think I have to replot the graph. And one more problem.
-q:a 0.029 or -q:a 10 is unfriendly for an average user. I think the value
should be roughly equivalent of LAME. I mean, if one use -q:a 2, the
result of average sound is roughly 96kbps/channel, which is the same
behavior as LAME -V2. Is applying new LPF method comment:51 easy?
