Hi, I'm very interested about FFT algorithm. I have a few question about FFT , Do you complete buffer before FFT calculation? or the FFT calculate at the same time the buffer is keep filling? 256N point have 128 Spectra output ... I very like your FFT spectrum project very much ... I'm thinking to implement it in 16F877 , dsPIC30F2011 .

Oh I think I know how you made it, it overtook me for a few seconds^^

Hello,
how do you make ca 228 frames per second?
I think the sampling of the audio signal takes quiet a long time for 256 Samples.

@lolerus because I render the graphic every loop, and do FFT only when buffer filled by using DMA. the FPS varies by how much graphic workload it has at a time.
