Classification: CPC H | IPC H

Claim 13:
14. A system comprising:
a first speaker associated with a wearable head device;
a second speaker associated with the wearable head device; and
one or more processors configured to perform a method comprising:
receiving a first input audio signal, wherein the first input audio signal corresponds to a first location of a virtual object in a virtual environment at a first time;
generating a first output audio signal and a second output audio signal, wherein the generating the first output audio signal and the second output audio signal comprises applying ITD to the first input audio signal based on the first location;
presenting the first output audio signal to the user via the first speaker;
presenting the second output audio signal to the user via the second speaker;
receiving a second input audio signal, wherein the second input audio signal corresponds to a second location of the virtual object in the virtual environment at a second time, wherein:
the virtual object is at the first location in the virtual environment at the first time, and the virtual object is at the second location in the virtual environment at the second time,
the wearable head device has a first orientation vector at the first time,
the wearable head device has a second orientation vector at the second time, and
the first location in the virtual environment relative to the first orientation vector is different from the second location in the virtual environment relative to the second orientation vector;

generating a third output audio signal and a fourth output audio signal, wherein the generating the third output audio signal and the fourth audio signal comprises applying a second ITD to the second input audio signal based on the second location;
presenting the third output audio signal to the user via the first speaker; and
presenting the fourth output audio signal to the user via the second speaker.
