Neat.  Let me clarify my application.  I'd like to do audio
teleconferencing on a packet-switched network.  With this I'd like to
place the different people in the conference in different places in
the audio space.  This would make it easier to separate what people
were saying.  I'm not sure separating midrange and high/low range
would work well for voices.

That leads to another question of mine.  Is there code for band reject
and band pass filters out there?  I realize that filters should be
specially tailored to the application.  However, since I don't know
much DSP, I'd love to just try filters with certain specified
tolerances.  I've read the FAQ without much luck.

Thanks for your input.
