Summary: lame 3.98.2 VBR lowpass

Initial Comment:
lame -V2 : for 48kHz WAV files the lowpass is about 600Hz lower than for 44.1kHz.

Encspot shows that lowpass is 18500Hz in both cases, but actually it is about 17900-18000 for 48kHz wavs and 18500-18600 for 44.1kHz.

Message:
LAME doesn't have a fine granuled lowpass filter. What you observe is due
to the way LAME uses the 32 subbands for filtering effect.
At some time in the future we may add a high quality (and slower) bandpass
filter.
