Hi again everybody,

As seen in this forum I'm not the only one with problems with spctrm routine.

Anyone knows other choices for power density calculation?

Thanx,

Uri

There are many algorithms out their. It is hard to find references though. One that you may find interest in is based on a sliding window short time fourier transform of "sliding window fourier transform" for short. It was in a paper published this last january and is a recursive routine. To boot, this routine is also of less complexity than a standard FFT based routine :).
