Matrices

Matrices can be used to change order of channels in the output file or to include/exclude one or more channels from the output file.
Here's an example on how to map 5.1 audio to 2.0.

• On the left side there are two values (FL and FR) because output is 2.0.
• On the right side there are six values (FL, FR, C, LFE, RL, RR) because input is 5.1.
• Output for FL channel will be created by combining FL and LFE from the input. All other channels will be discarded.
• Output for FR channel will be created by combining FR and LFE from the input. All other channels will be discarded.

Channel Names

FR	Front Right
FL	Front Left
LFE	Low Frequency Effects
RL	Rear Left
RR	Rear Right
