LinSmooth

Overview

Linear Smoothing with separate Up/Down time constants

Discussion

This module restricts the rate of change of a signal in a linear fashion. It computes the steps by calculating the delta between the current and the target value and its rate defined by a time constant. Different smoothing times for up- and down stepping can be defined.

Type Definition

CODE
typedef struct _ModuleLinSmooth
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    FLOAT32 smoothingTimeUp;                      // Smoothing Time Up in ms
    FLOAT32 smoothingTimeDown;                    // Smoothing Time Down in ms
    FLOAT32 slewDown;                             // State variables. One per channel
    FLOAT32 slewUp;                               // State variables. One per channel
    FLOAT32 slewStepsUp;                          // Inverse of slew
    FLOAT32 slewStepsDown;                        // Inverse of slew
    FLOAT32* state;                               // State variables. One per channel
    FLOAT32* slew;                                // State variables. One per channel
    INT32* counter;                               // State variables. One per channel
    FLOAT32* targetValue;                         // Ramping target value
} ModuleLinSmoothClass;
