Overview

Asymmetric clipper module with separate upper and lower clipping thresholds

Discussion

Asymmetrical clipping, where the upper and lower thresholds are exposed as parameters. By setting $clipLower=-clipUpper$ symmetrical clipping can be achieved.

Type Definition

typedef struct _ModuleClipAsymFract32
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    FLOAT32 clipLower;                            // Lower clipping threshold
    fract32 clipLowerFract32;                     // Lower clipping threshold in fract32 form
    FLOAT32 clipUpper;                            // Upper clipping threshold
    fract32 clipUpperFract32;                     // Upper clipping threshold in fract32 form
} ModuleClipAsymFract32Class;
