signal processing - Mixing PCM audio samples - Stack …
https://stackoverflow.com/questions/21508372/mixing-pcm-audio-samples
I read that best way to mix multiple audio PCM samples is to take the average of the samples each frame. So if I am adding together say 5 16 bit samples before dividing by 5, there is obviously a good chance it will have a value greater than a 16bit short can hold. So when mixing together multiple 16 bit samples, do I store them all in int first and add them and …

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. Is this level of distortion acceptable in high-quality audio synthesis?
