[MP3 ENCODER] Filters

[Joshua Bahnsen]

I just want to make sure I understand what using a filter actually does. This is what I think it does, tell me if I'm right. Say you want to encode a file at 128 Kbps, if you had a filter that cut off at 16 Khz, then that would leave more bytes open for the range between the low cutoff and 16 Khz, right? If you didn't have the filter, then there is less available for the midrange because you are also encoding higher rates that the average person can't hear, am I getting this at all? I've read many places that 16 Khz is the normal cutoff of human hearing, so I assume that encoding at 160 and 192 with recent versions of lame, it just gives the opportunity for higher samples because there is more to work with, right?   Joshua Bahnsen
