How to multiply two sounds?

[CrocoDuck]

O Hay! So, I'm working on my final thesis, regarding physical modelling synthesis, and I would like to make some demostration, in the introductory part, of the intermodulation phenomenon, that is when two sounds of different frequency are combined in a non linear medium. The resulting sound is the product of the wavefunctions of the two initial sounds. How can I achieve this with a sythesizer and/or a plugin? Basically, I would like to synthesize two sounds of different frequency an then operate a multiplication of the two waves.

Are you speaking of ring modulation? There's [s]an app[/s] a LADSPA plugin for that...

Uh! Nice! I've tested it with 2 Yoshimis and Baudline... Seems to work as expected, I can see the bands for the sum and difference of the frequencies. Thanks.

Yeah, is a kind of, but I wanto to modulate a pure tone using another pure tone with a close frequency (a tone higher, more or less), to make audible the resulting tones having frequency respectively the sum and the difference of the first ones.
