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...)
