Thanks guys,

The ASP course is great and everything is well explained.
I had several moments of ooooh's and ahaaa's during the classes.

Dave, today the class starts explaining STFT and spectrograms.

Today i followed the new class about window functions (ASP course) and discovered an error in my blackman and blackman-harris window calculations.
Corrected these errors and uploaded a new exe. (see Reply #27 )

You can download a frequency sweep file (see Reply #27 ) and test the window functions.
Notice the differences between main lobes and side lobes of the window functions.
To look at the frequency sweep turn off FFT Smoothing.

Yes, i'll try to understand as much as possible as explained in the ASP course and do the "assignments" in asm.
Next step is plotting the Phase and Unwrapped-Phase.

Do you know if after the end of the course would be possible to download the course? It's a bit difficult for to me to follow it, but seems to be very interesting :t
