Absolutely! Also "ring modulation" is amplitude modulation without
additional "dc" offset.
Meaning: just modulate a sound's amplitude with another sound
(usually just a sine wave),
without adding a constant amplitude value in:
(usually 1) (audio freq.,usually) (sine, usually)
a1 oscil someamp, somepitch , somefunc
a2 soundin somefilecode
aout = a1 * a2
(aout now has a "ring-modulated" copy of the sound in file pointed
to by "somefilecode")
NOTE: adding an amplitude value to a1: eg: aout = ((a1 + 1000) *
a2) would produce classic amplitude modulation, rather than "ring
modulation"
Should do the trick! (Have fun...)
