Algorithm(s) to mix audio signals without clipping ...
https://dsp.stackexchange.com/questions/3581/algorithms-to-mix-audio-signals-without-clipping
From reading around, a common method of mixing is: result = A + B - AB, where A and B are the two normalized samples being mixed, and AB is a term to ensure louder sounds are increasingly "soft-clipped". However, this introduces a distortion of the signal.

So, the algorithm goes: Find out the volume in which you want the output sound to be. It can be the average or maxima of one of the signals. Normalize both signals with this factor: s1 = (s1/max (s1))*factor s2 = (s2/max (s2))*factor Add them together and normalize the result with the same ...

Your mixing code is very odd - you seem to be adding a non-linear term which will result in distortion - it seems to be a hack specifically for 8 bit PCM where the dynamic range is very limited, but you probably don't need to worry about this for 16 bit PCM.

Algorithm to mix sound (13) convert the samples to floating point values ranging from -1.0 to +1.0, then: out = (s1 + s2) - (s1 * s2); Will introduce heavy distortion when |s1 + s2| approach 1.0 (at least when I tried it when mixing simple sine waves). I read this recommendation on several locations, but in my humble opinion, it is a useless approach.

PCM audio is used in CD, DVD, Blu-ray, and other digital audio applications. When used in surround sound applications, it is often referred to as Linear PCM audio or Linear Pulse Code Modulation (LPCM). PCM audio produces a series of numbers or digits, and hence this process is called digital. Each one of these digits, though in binary code, represents the …
