[vorbis] 16 KHz clip-off?

[Maik Merten]

Hello,

congratulations to the Ogg Vorbis team - RC2 sounds good.
But... RC2 in 128 kbps mode seems to clip off all frequencys
beyond 16 KHz. On the tracks I tested Beta 4 gave response
even beyond 18 KHz.

Some testings on a randomly chosen track:
(other tracks gave similar results)

Artist: Judas Priest
Album: Jugulator
Title: Bullet Train

Beta4: 127 kbps, ~ 18 KHz (!)
  RC2: 132 kbps (!), ~ 16 KHz

This seems even more strange to me as RC2 benefits from channel
coupling...

BTW: As 128 kbps mode produces average bitrates higher than 130 kbps
(please keep in mind that I am testing with Heavy Metal music, so
results for Britney Spears and Back Street Boys may vary ;-) )I would
be happy if 112 kbps mode is back in RC 3...

bye,

Maik Merten
