Data Structures

3D Sound Setup Structure

You specify the configuration of the listener's speakers using a 3D sound setup structure. A 3D sound setup structure is defined by the SSpSetupData data type.

typedef struct SSpSetupData {
   UInt32                     speakerKind;
   float                      speakerAngle;
   UInt32                     reserved0;
   UInt32                     reserved1;
} SSpSetupData;
