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 the example matrix used to map 5.1 audio to 2.0.
- Because output is 2.0, there are only two values (FL and FR) on the left side of the matrix.
- Because input is 5.1, there are six values (FL, FR, C, LFE, RL, RR) on the right side of the matrix.
- In this example FL output will be created using FL and LFE from the input. All other channels will be discarded.
- In this example FR output will be created using FR and LFE from the input. All other channels will be discarded.
| FR | Front Right |
| FL | Front Left |
| LFE | Low Frequency Effects |
| RL | Rear Left |
| RR | Rear Right |
