Comment (by klaussfreire):

 Replying to [comment:28 Kamedo2]:
 > Whitenoise.flac at 384kbps, ffmpeg_aac320k_collapse.flac at 320kbps is
 strange, too.

 I didn't try the collapse ones at 320k, though I tried at 384 and sounded
 nice. I'll try again when I have a chance though.

 However, whitenoise 384 gives me an error, seems 384kbps is too much for
 mono. The whitenoise I mention is generated with the random generator,
 I'll try with the flac first chance I get.
