Brutefir is a high performance convolution engine. You convolve a signal with 
a specific impulse response. You can for instance use it to make a 
multichannel reverb unit (this is a popular technique at the moment), 
provided you have an reverb impuls response. There's a nice bunch of IR's 
available at http://www.noisevault.com/.

I haven't played with this nearly as much as I'd want to... I'm also not sure 
if the impulses at the site referenced actually works with brutefir. I think 
I tried some a while ago, and I remember I had problems.
