You need to get a sound from a set of simple waves of different frequencies. As I understand it can be done by folding waves, but how to do this I have not found a clear answer, would be grateful for any tips.

Add up literally, i.e. y(t) = sin(w_1 * t + phi_1) + ... + sin(w_n * t + phi_n),
where w_n and phi_n are frequencies and phases of harmonics.
