Overview

Phase invert module

Discussion

This module inverts the phase of a signal. Inverting the phase is simply multiplying by -1. The variable isInverted is a Boolean which controls the behavior. When isInverted=1, the module multiplies the input signal by -1. When isInverted=0, the module passes the input signal through unchanged. Internally, the module uses a first order smoother to seamlessly switch between +1 and -1. The smoothing time of the switching process is set by the smoothingTime variable.

Type Definition

typedef struct _ModuleInvert
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    INT32 isInverted;                             // Boolean that specifies whether the signal is inverted (=1) or not (=0).
    FLOAT32 smoothingTime;                        // Time constant of the smoothing process.
    FLOAT32 currentGain;                          // Instantaneous gain applied by the module. This is also the starting gain of the module.
    FLOAT32 smoothingCoeff;                       // Smoothing coefficient.
} ModuleInvertClass;
