GALA Gain
Description
In GALA Gain block, the gain applied to the input signal varies with the changes in the control input(Speed/Engine noise).

Configurable Parameters
| GUI Parameter Name | Default Value | Range | Function Description |
|---|---|---|---|
| Slope | 0.01 | 0.01 to 1.0 | It is used to multiply with the control input |
| DBGain | 0.1 | 0.0 to 15.0 dB | Scales the input signal |
| NumChannels | 1 | 15 | Number of input and output channels. Change in this value requires re-compilation |
DSP Parameters
| Parameter Name | Description | ADSP-214xx/SC5xx/215xx |
|---|---|---|
| Slope | Scales the speed(Control input) | Float |
| DBGain | Scales the input signal | Float |
| RampUpSlew | Rate of smooth transition of signal from low level to high level | Float |
| RampDownSlew | Rate of smooth transition of signal from high level to low level | Float |
DSP Parameter Computation
RampUpSlew = 10^(1/(FS * 20))
RampDownSlew = 10^(-3/(FS * 20))
