(8.D.2.5) STOmni2
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;
