You're welcome! I'm glad my update found its way to you! (danger: potential infinite regress)freakazoid wrote: Thanks so much! Glad my request found its way to you!

This week I'm working on spectral analysis, and it's coming along pretty well. I'm using Kiss FFT to do the actual FFT, but that only gets me about half the way there, the rest is all gnarly scaling, window functions, plumbing, wrapping, etc. The goal is a Spectrum dialog with a graph, similar to the existing RMS statistics/histogram dialog. Parameters should include:
Window size (droplist: 256/512/1024 etc.)
Window function (droplist: Bartlett, Welch, Hann, Hamming, Blackman, Blackman Harris)
Frequency scale (droplist: linear vs. log)
Separate channels (checkbox: if checked, show one spectrum for each channel, else channels are averaged together to yield a single spectrum)
extra credit: additional control over the plotting, e.g. lines versus filled area
After this gets done, I might take a stab at a real-time spectrum analyzer window. Between the newly-added peak meters and the Spectrum dialog I'll have most of the needed bits and pieces. It's really kind of a fusion of the two. Might be interesting to show a real-time spectrum for each channel of a surround file...
