Two modes are supported, "Inferred" and "Virtual". Generally, "Inferred" is recommended.

ModeDescription
InferredThis mode is optimised for use with material that has been mixed using conventional panning techniques, such as equal-power panning or VBAP. The approach produces smooth transitions when sounds pass between speaker locations.
VirtualThis mode simply places each of the audio channels in their appropriate speaker direction. This can be worth trying when the mix has not been put together by conventional panning and the channels have a complex phase relationship.
