Soft Clipper - Standard Cubic
Description
The Standard Cubic block is a soft clipper that uses a cubic function to clip the level of the input signal. As the input signal reaches the clip threshold, the algorithm rounds the edges for a smoother clipped output.

Configurable Parameters
| GUI Parameter Name | Default Value | Range | Function Description |
|---|---|---|---|
| —————————————- | ———————- | —————— | —————————————- |
| IsLinear | True | True / False | Allows the values in linear or DB |
| Alpha | 1 | 0.1 to 10 | This pre/post scalar determines the amount of clipping that will occur. Although this influences the threshold value of the clipper, this is not the value at which clipping occurs |
| NumChannels | 1 | 20 | Number of input and output channels. Change in this value requires re-compilation |
