[alsa-devel] mixing audio waves for analysis!

Hello.

Since I haven´t got any awnser for the previous question, I decided to formulate a new one, perhaps with a better meaning of what I really need!

I need to combine two waves that I created in two diferent functions. So, I have the function generate_sine_one and generate_sine_two with defferent frequencies and amplitudes.

Ok, what I need is to find a way to combine these two waves. I been searching through alsa api in a effort to solve my problem but I couldn´t find a proper solution.

Does anyone know a program or a tutorial where I could get some reference of this type of procedure?

Tks a lot!
