[vorbis-dev] Can compressed music sound better thanuncompressed?

[Matt]

Hi,
couldn't help noticing an interesting topic passing by.  My background is
Neuroscience; as part of this I helped a friend with a project on the
psychoacoustics of the human perception of timbre w.r.t music.  Very
interesting.  Some side effect that I noticed with some encoding schemes is
that the timbre became altered, i.e. some harmonics became accentuated and
therefore cleaner.  I remember a couple of years ago I encoded a friends
music in MP3 at 56kbps and 128kbps .... both created a more hollow sound to
appear, and sure enough the power spectrum showed the altered ratios.  I
didn't really follow it up.  But the interesting thing from the earlier
study on timbre was that a degree of hollowness was appealing to listeners.
Not sure if anyone finds this interesting, just thought I'd mention it.
