Overview

ST Stereo Widening module

Discussion

Omni2 Stereo widening effect applies to Loudspeakers (not headphones).

This version supports 48KHz sample frequency only and an input blocksize from 96 to 480 samples.

The module takes two arguments: Omni2CentreOutput and AudioMode.

Omni2CentreOutput : 0 to disable the center output (for 3.0), 1 to enable the center output (3.0)

AudioMode : Can be one of the eAcMode_Supported enumeration values (AMODE10 or AMODE20)

Type Definition

typedef struct _ModuleSTOmni2
{
    ModuleInstanceDescriptor instance;            // Common Audio Weaver module instance structure
    INT32 nAPIResult;                             // Return status for last call into the ST API
    INT32 audioMode;                              // Audio mode 1 - Mono, 2 - Stereo
    INT32 centerEnable;                           // Enable center output
    INT32 enable;                                 // Block enable
    INT32 strength;                               // Strength percent (0 - 100)
    INT32 listeningAngle;                         // Omni2 listening angle (10, 20, or 30 degrees)
    void * pGlobals;                              // Points to the global variables structure
} ModuleSTOmni2Class;
