>From a math POV there is no "correct" way to do this, but if the
samples in the m channels represent m uncorrelated audio signals you
might want to attenuate the overall signal gain by 3 dB for each
channel that you add.

This follows the increase in overall volume that you get when m
uncorrelated sources play together.
