Hi everyone.

� I guess. I find pre-echo most noticeable when the click from kick drums turn into a
"th" sound. But other than that, I tend not to listen to high frequencies as much as
low frequencies, & when possible I tend to filter the highs out. I guess I'm a biased
listener :-/
� I'd be interested to see what happens when MP3 encoders try to replicate a spike
that's about 50 samples long.

� So would such poor frequency resolution be fine as long as there are no masking
approximations done on what appears to be a DC signal? If we're only talking about 2
(3?) frequency bands to represent the entire low & mid ranges, it doesn't sound like
much to exclude. I'm gonna have to start looking for papers on all this stuff.
