A small, incomplete C# app to play with FFTs.

It does require .NET framework 3.5 (Yes, its a big download... just do it!)

Some of the features don't work... UI is based off of the FFT Laboratory 
Java applet.

I know I shouldn't be, but I'm shocked at how fast it actually updates.. :)

The sample is bad, since the forward transform scales, where the inverse 
does not. Play with the bars on the bottom to do an iFFT, draw a 
waveform on the top to play with an FFT...

Have fun.
