Thanks, Steve.  I ended up just averaging every n
samples to do the downsampling.  This way allowed me
to use a default downsampling factor of 1/10, which
isn't bad.

The following file types are now supported: Mp3, Ogg,
Wav, and Raw.  The program can also be piped to over
stdin, so long as the piped input is raw.

Requires sox and mpg123.  You can grab it at
http://jaydolan.com by clicking on the "etc" page. 
It's GPL'ed.  Feedback/criticism is welcome.  Thanks
for your help, guys :)
