Digital Signal Processing Help!

I've been working on, for a couple weeks now, programing ( more like trying to ) a small program that either would use FFT or Geortzel's Algorithm to detect QC-II tones from an audio input on a computer sound card.

Maybe one of you could point me in the right direction or maybe I should direct this to a computer programming specific forum. I have done extensive Google searching but found nothing quite specific to my questions.

Thanks

You'd probably have better luck on a DSP forum. It's definitely possible. Andrew Pollack is completing his version right now. See this thread:

I assume you're trying to do this in real time, as opposed to post-processing a file that's already been recorded...that's relatively simple...the real time stuff is quite a bit more difficult.
