Soft Clipper - Standard Cubic


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.

Targets Supported

Configurable Parameters

GUI Parameter NameDefault ValueRangeFunction 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 120Number of input and output channels. Change in this value requires re-compilation
