Overview
M-input x N-output mixer
Discussion
This module implements a fixed point full M-input x N-output mixer with a total of MxN coefficients. The coefficients are contained in the coeffs matrix with the gain from the ith input to the jth output is found at coeffs(i, j). Note, this mixer is not smoothly updating and changes to the gain coefficients may result in audible clicks. Use the MixerSmoothedFract32 for clickless updates.
...
When the module is bypassed, it copies the ith input channel to the ith output channel. If the module has more output channels than input channels, the remaining output channels are set to 0.
