Yes - and I think too that its somewhat worth mentioning here that 
the spectral software, etc...is much prettier to look at than do much 
else with...

I do not mean to minimize their overall value or anything, but having 
worked with way too expensive FFT/waveform/spectrum analyzers-a long 
time ago at a then very rich utility at which I still work - I can 
tell you that their value in creating sounds is minimal, especially 
compared to a human with imagination!

A post recently said FFT was a DSP thing - very correct - thats why 
FFT is everywhere in the digital signal analysis world: because its 
really easy to DO on a 'puter - but it don't tell you much about 
sounds, especially ones that have any phasing, pyscho 'movement' in 
them (i.e. the really cool sounds)because there's too much going on!

They are fun to look at for while however and you can learn alot 
about sound structure, etc...especially for basis analog stuff but 
the fun wears off quickly once you get the hang of it...unless of 
course your goal is creating visual art, like something that can be 
effectively projected up into the sky, on a cloud, or at night - 
that'd be totally cool...

Ok - i'll shut up,
