Re: [chuck-users] Using Fourier Transform
Those are some great FFT resources, Rebecca - thanks for sharing! I also wholeheartedly second the recommendation for the DSP Primer book. In addition, I have linked the following FFT overviews to people who are intimidated by articles that lean towards the more academic end of the spectrum: 1. The DFT "à pied": Mastering the Fourier Transform in on day: http://www.dspdimension.com/admin/dft-a-pied/ (The author of this article acknowledges that it'll take more than one day to truly grok DFT.) 2. Katja's homepage on sinusoids, complex numbers and modulation: http://www.katjaas.nl/home/home.html (Katja uses wooden anatomical dolls and photos to reinforce the mathematical relationships between complex numbers, sinusoidal waveforms, etc - useful for building up mental models) Cheers, Anthony.
Many thanks! I'll try hard to study it all.

I'd forgotten about this post: http://forums.tigsource.com/index.php?topic=14590.msg425647#msg425647 It has a few things going for it: 1) A couple great pictures 2) Practical focus (generating shaped noise) 3) Code interspersed -- Tom Lieber http://AllTom.com/ http://ckvlang.org/
This is the best explanation of FFT I've ever seen. Thanks!
