C Specification

The xrSubmitSoundObjectBufferBD function is defined as:

// Provided by XR_BD_spatial_audio_rendering
XrResult xrSubmitSoundObjectBufferBD(
    XrSoundObjectBD                             soundObject,
    const XrAudioBufferBD*                      buffer);

Parameter Descriptions

Description

This function submits an audio buffer to a sound object XrSoundObjectBD. The corresponding function for a sound field XrSoundFieldBD is xrSubmitSoundFieldBufferBD.

This function must only be called during an audio period, which is the time period after a successful, not timed out call to xrWaitAudioPeriodBD and before a successful call to xrEndAudioPeriodBD, otherwise the runtime must return XR_ERROR_CALL_ORDER_INVALID.

For each sound object, this function must not be called more than once per audio period, otherwise the runtime must return XR_ERROR_CALL_ORDER_INVALID.

The buffer must

If any of the above conditions are not met, the runtime must return XR_ERROR_VALIDATION_FAILURE.

When valid audio is submitted, the runtime must correctly process and render the spatial audio.

Applications must not call this function concurrently with xrWaitAudioPeriodBD or xrEndAudioPeriodBD. Doing so may result in undefined behavior.
