AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
Claim 14 is cancelled.
Claims 1 and 15-18 are determined to be patentable as amended.
Claims 2-13, dependent on an amended claim, are determined to be patentable.
1. A spatialized audio system, comprising:
a sensor to detect [ a ] head pose [ and a second head pose ] of a listener; and
a processor to:
render, based on the detected head pose of the listener, first audio data corresponding to a first plurality of sources, each of the first plurality of sources having respective ones of a first plurality of positions, to second audio data corresponding to a second plurality of sources, each of the second plurality of sources having respective ones of a second plurality of positions [ ;
render, based on the detected second head pose of the listener, the second audio data to third audio data corresponding to a third plurality of sources, each of the third plurality of sources having one of a third plurality of positions; ] and
reproduce, based on the second [ third ] audio data, a spatialized sound field corresponding to the first audio data for the listener,
wherein the first plurality of sources are virtual sound sources,
wherein the second plurality of sources are virtual sound sources and consists of fewer sources than the first plurality of sources, and
wherein rendering the first audio data to the second audio data comprises each of the second plurality of sources [ the processor ] recording [ a first ] virtual sound generated by [ corresponding to each of ] the first plurality of sources [ as the first virtual sound would be perceived ] at a respective one of the second plurality of positions [ as the second audio data, and
wherein rendering the second audio data to the third audio data comprises the processor recording a second virtual sound corresponding to each of the second plurality of sources as the second virtual sound would be perceived at a respective one of the third plurality of positions for reproducing the spatialized sound field for the listener] .
15. The system of claim 14 [ 1] , wherein rendering the second audio data to the third audio data comprises warping the second audio data to the third audio data.
16. The system of claim 14 [ 1] , wherein the sensor detects the detected second head pose of the listener immediately before the processor renders the second audio data to the third audio data.
17. The system of claim 14 [ 1] , wherein the third plurality of sources consists of fewer sources than the second plurality of sources.
18. The system of claim 14 [ 1] , further comprising a plurality of speakers corresponding to the third plurality of sources to produce sound based on the third audio data.
