I have downloaded the MP3 and converted with MPeg Suite 1.5 Then I
loaded it in SoundForge 6.0 and took a look at the FFT (full spectrum
and level down to -150 dB); there was signal in that band, but is was
at all times much lower then the other bands. It might have something
to do with the massive clipping that occured in the piece, maybe the
WAV to MP3 coder had some kind of high freq band protection to
minimize the audible clipping effects? After all, I looked at the
waveshape, and inspite of the clipping 'seen' it wasn't to bad to
listen to ; I have heard worse in my personal recordings :)
