So you have managed to merge your audio streams and now you want to know how to write that to a wav file?

The audio I merge overlap each other. But I do not want it to overlap, instead adding on to it.

What is your input data, what is your required output and what code did you try so far? do you end up with a 4xn array instead of a 2xn array? Do you have a method to determine which sounds overlap?
