Has anybody written a fast audio spectrum analyser in DJGPP?  I'm
curious to know how this is done, and how I might implement it into a
MP3 project of mine.

Am I correct in thinking that I must perform a FFT on the audio stream? 
If so, where can I find info (perhaps a beginners howto) on FFT?  If
not, how else would I create an analyser?

Thanks a ton!
