Typing "waterfall spectra audio PC windows" into Google gets almost 200 hits :) Loot and lots of software out there. Before MOTM, I was toying with designing a modular synth design called Titan. The "VCO" board had 256 waveforms (sines, saw, whatever) with 0.1dB amplitude adjustments on each one. The pc boards were about 14" x 8" and the estimated cost was about $4500 each. They plugged into a Fibre Channel backplane. Wheee!!! Paul S.
