A device and method for backward compatibility for virtual reality (VR), mixed reality (MR), augmented reality (AR), computer vision, and graphics systems. The device and method enable rendering audio data with more degrees of freedom on devices that support fewer degrees of freedom. The device includes memory configured to store audio data representative of a soundfield captured at a plurality of capture locations, metadata that enables the audio data to be rendered to support N degrees of freedom, and adaptation metadata that enables the audio data to be rendered to support M degrees of freedom. The device also includes one or more processors coupled to the memory, and configured to adapt, based on the adaptation metadata, the audio data to provide the M degrees of freedom, and generate speaker feeds based on the adapted audio data.
A device comprising:
The device of claim 9, wherein the M degrees of freedom includes three degrees of freedom, the three degrees of freedom comprising yaw, pitch, and roll.
The device of claim 9, wherein M=0.
The device of claim 13, wherein the one or more processors are further configured to multiply the effects matrix by a rendering matrix to obtain an updated rendering matrix, and wherein the one or more processors are further configured to apply the updated rendering matrix to the audio data to:
The device of claim 18, wherein the wearable device comprises a watch, glasses, headphones, an augmented reality (AR) headset, a virtual reality (VR) headset, or an extended reality (XR) headset.
The device of claim 22, wherein the device is one of a vehicle, unmanned vehicle, a robot, or a handset.
The device of claim 24, wherein the processing circuitry comprises one or more application specific integrated circuits.
A method comprising:
A device comprising:
