[sdiy] Filter banks & variability

[Tim Ressel]

Yo,

I've been thinking (yes, i know, the judge said not
to...but I can't help it) about filter banks. Sounds
like a wonderfull idea, and many people have gotten
great results. But all those filters to build...yikes!
And if you try and make a 24-row parameric
filter...double yikes! 96 knobs?!?  

I'm thinking this is one of those times DSP can come
to the rescue. There is a way to use FFTs to do
filtering. That way you just draw the filter shape you
want, and presto! 

I wonder if PCs are now fast enough to be able to do
DSP stuff in real time using a sound card for I/O? 

Hmmm.....
