Would you use a C++ plugin to accomplish this? What about quicktime on the mac, would it assist? Image Magik? Is the MonkeyBread Plugin for that free? _________________ If at first you don't succeed... Try REALBasic.

It's pretty fast but for serious processing or 2D FFT I use declares to the vDSP library (mac). Gaussian blurs might be in there too, it has convolution kernels but I never figured those functions out. I have rb code for simple 3x3 convolution kernels. Calling external functions will greatly speed this up. Fullscreen spectrograms went from like 3 seconds per frame with rb only code to like 10fps. I'm guessing Windows and Linux have a comparable library of highly optimized FFT. I can dig this stuff up if you want.
