The XrAudioBufferChannelLayoutBD enumeration describes the channel layout of audio buffers.

// Provided by XR_BD_spatial_audio_rendering
typedef enum XrAudioBufferChannelLayoutBD {
    XR_AUDIO_BUFFER_CHANNEL_LAYOUT_INTERLEAVED_BD = 0,
    XR_AUDIO_BUFFER_CHANNEL_LAYOUT_PLANAR_BD = 1,

Description

Enum Description

XR_AUDIO_BUFFER_CHANNEL_LAYOUT_INTERLEAVED_BD

XR_AUDIO_BUFFER_CHANNEL_LAYOUT_PLANAR_BD

indicates that audio samples are stored in a planar layout, where all samples for one channel are contiguous in memory (e.g. LLL…​RRR…​ for stereo)
