Overview

Phase invert module

Discussion

This module inverts the phase of a signal. Inverting the phase is simply multiplying by -1. When the second argument NUMPINS is 1, then the phase invert control is applied to each individual channel. Otherwise the phase invert control is applied to each individual input pin as a whole. The array .isInverted is used for phase invert control. The array length is updated by the prebuild function.

...

By default, the inspector for the module has the control checkboxes organized in a vertical stack. By setting the optional third argument TRANSPOSE = 1 turns the control into a horizontal stack.

Type Definition

typedef struct _ModuleInvertN
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    INT32 numControls;                            // Number of individual invert controls
    FLOAT32 smoothingTime;                        // Time constant of the smoothing process
    FLOAT32 smoothingCoeff;                       // Smoothing coefficient.
    INT32* isInverted;                            // Boolean that specifies whether the signal is inverted (=1) or not (=0). One per each pin.
    FLOAT32* currentGain;                         // Instantaneous gain applied by the module. This is also the starting gain of the module.
    FLOAT32* gain;                                // Target gain.
} ModuleInvertNClass;
