What sound examples? How can you possibly have sound examples for a dataflow simulation tool? You could basically implement every imaginable sound synthesis method in the world, so what will the sound examples be?
These are sounds produced with the example application programs distributed
with Sonic Flow. The applications are afmsynth (an AM- and
FM-capable synthesizer), chorus-flanger (a chorus and a flanger
effect), multitap (a 4-tap delay line), parameq (a
3-band fully parametric equalizer), reverb (a reverb algorithm) and
wah-wah (a 2-band wah-wah).
Most of the sounds are effects, and we have used the sample sf_helmi.wav as the input signal to the effects. Note that the input signal already contains impulsive "cracks", which some of the effects may emphasize.
The following table contains not only a description of the effect/program currently in use, but also the command line parameters used to produce every example sound.
