I think the default lowpass values are quite useless, especially in low 
bitrate encodings. I'm doing live mp3 streaming with icecast, and 
generate a 24 kb/s 22.05kHz stream (along the 96 kb/s stream). The 
default lowpass for 24 kb/s is about 4.5kHz, which is totally 
unaccaptable. If I override it to 8.5kHz, it's quite OK.


At first this whole automatic lowpass troubled me quite a lot. IMHO lame 
should not imply any changes to the sound unless specified explicitly. 
There could be a 'detect best' option, so that it would use all these 
heuristic values, like downscaling the sample rate and/or applying a 
lowpass filter. (The 24 kb/s 22.05kHz stream gets downscaled to 16kHz by 
default, I manually have to override this so that there is no change.)

Also, when using lame as a shared library, and calling all the 
functions, I also found that there is an automatic lowpass generation. 
This is even more annyoing. IMHO these features should only be at the 
command line program, not when calling the API.

(Yes, I know the mailman doc recommends no reply-to: to the list.)
