I did a waveform soft support using FFTW. Unfortunately I have problemsto re-compile it at the moment. :-(


I will inform you when it is ready to use.

Has anyone done a routine for the aSub record (or similar) which does anfft?
My input is complex data (two waveforms I and Q) as a function of time(512 samples). Data updates come at ~5Hz.
I was thinking of using

Suggestions?
