C Specification

The XrSoundObjectDirectivityCardioidBD structure is defined as:

// Provided by XR_BD_spatial_audio_rendering
typedef struct XrSoundObjectDirectivityCardioidBD {
    XrStructureType    type;
    const void*        next;
    float              alpha;
    float              order;
} XrSoundObjectDirectivityCardioidBD;

Members

Member Descriptions

  • type is the XrStructureType of this structure.

  • next is NULL or a pointer to the next structure in a structure chain.

  • alpha describes the shape of the cardioid polar pattern.

  • order is the sharpness of the cardioid polar pattern.

Description

To describe the directivity of a sound object by a cardioid polar pattern, applications may chain XrSoundObjectDirectivityCardioidBD to the XrSoundObjectConfigBD::next chain.
