System and method for performing panning for an arbitrary loudspeaker setup

A method of performing panning for an arbitrary loudspeaker setup, comprising:

• determining a placement of one or two virtual loudspeakers within the loudspeaker setup, wherein the loudspeaker setup includes a plurality of real loudspeakers;
• determining vector base amplitude panning (VBAP) gains, wherein the VBAP gains include gains of the real loudspeakers and the one or two virtual loudspeakers;
• redistributing gains of the one or two virtual loudspeakers to the real loudspeakers to ensure preservation of total energy;
• and
• generating loudspeaker outputs for the real loudspeakers in the loudspeaker setup to be played back, wherein the real loudspeakers have the redistributed gains of the at least one virtual loudspeaker.

A method of performing panning for an arbitrary loudspeaker setup, comprising:

• receiving audio content for playback via a plurality of real loudspeakers in the loudspeaker setup;
• determining whether the audio content is Higher Order Ambisonics (HOA) content;
• when the audio content is HOA content, generating a virtual loudspeaker array including a plurality of virtual loudspeakers and projecting the HOA content to the virtual loudspeaker array;
• determining a placement of one or two placed virtual loudspeakers within the loudspeaker setup, wherein the loudspeaker setup includes a plurality of real loudspeakers;
• determining vector base amplitude panning (VBAP) gains, wherein the VBAP gains include gains of the real loudspeakers and the placed one or two virtual loudspeakers;
• redistributing the gains of the one or two placed virtual loudspeakers to the real loudspeakers to ensure preservation of total energy;
• and
• generating loudspeaker outputs for the real loudspeakers in the loudspeaker setup to be played back, wherein the real loudspeakers in the loudspeaker setup have the redistributed gains of the one or two placed virtual loudspeakers.

A system for performing panning for an arbitrary loudspeaker setup comprising:

• a storage storing instructions;
• and
• a processor coupled to the storage, wherein the processor is to execute the instructions to:
• receive audio content for playback via a plurality of real loudspeakers in the loudspeaker setup,
• determine a placement of one or two placed virtual loudspeakers within the loudspeaker setup, wherein the loudspeaker setup includes a plurality of real loudspeakers,
• determine vector base amplitude panning (VBAP) gains, wherein the VBAP gains include gains of the real loudspeakers and the one or two placed virtual loudspeakers,
• redistribute gains of the one or two placed virtual loudspeakers to the real loudspeakers to ensure preservation of total energy, and
• generate and transmit the loudspeaker outputs to be played back by the real loudspeakers.
