12 * Description of matrices
13 * - Inputs are rows
14 * - Outputs are columns
15 *
16 * I1 -> | I1 | I2 | I3 | I4 |
17 * I2 -> | I1 | I2 | I3 | I4 |
18 * I3 -> | I1 | I2 | I3 | I4 |
19 * ↓ ↓ ↓ ↓
20 * O1 O2 O3 O4

23/*
24 * Naming Conventions:
25 * - `_2` = Indicates an additional 2 channels of static or non-diegetic audio, or in this case stereo
26 * - `Pairs` = Indicates the spatial audio files are already doubled in sets of binauralized stereo files
27 * - `_SIM` = Indicates the soundfield is shrunken to a spherical projection to undiverge the input sources
28 * to make use of all the output channels and simulating a more realistic transcode
