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,
