| The example shows The module configured to two inputs and three output channels with three independent FIR Filter coefficient sets. The three coefficients are Low pass FIR filters with cutoffs 2.4KHz,4.8kHz and 7.2KHz. | The example shows The module configured to a single input, single output configuration. The input is a sine sweep, sweeping linearly from 50Hz to 20kHz. The multiband compressor bands are configured to provide compression of 12db,0db,5dB and 30dB at an input level of 0dB. |
| The output plots for the configuration are shown below. | |
