AKRESULT __cdecl AK::SoundEngine::SetListenerSpatialization ( AkUInt32  in_uIndex,
bool  in_bSpatialized,
AkChannelConfig  in_channelConfig,
AK::SpeakerVolumes::VectorPtr  in_pVolumeOffsets = NULL  

Set a listener's spatialization parameters. This let you define listener-specific volume offsets for each audio channel. If in_bSpatialized is false, only in_pVolumeOffsets is used for this listener (3D positions have no effect on the speaker distribution). Otherwise, in_pVolumeOffsets is added to the speaker distribution computed for this listener. Use helper functions of AK::SpeakerVolumes to manipulate the vector of volume offsets in_pVolumeOffsets.

If a sound is mixed into a bus that has a different speaker configuration than in_channelConfig, standard up/downmix rules apply.

AK_Success if message was successfully posted to sound engine queue, AK_Fail otherwise.
