What are the effects of multiplication of two different sound? An neither of them are constant, like two different songs, or one track of instrumental and one of vocals.

Answer 1

A simple Google search came up with this:

Did you search for it at all?

But basically what happens is you end up creating an envelope where the second acts as a "coefficient" of sorts.

You also end up with a reduction of sound levels (since a decimal times a decimal is less both of them), so you'll need to amplify the signal a bit to retain volume.

The page I linked gives a lot more explanation and has a lot of the algebra needed to write up a code to implement it. Look there if you have any more questions.
