AS A RESULT OF REEXAMINATION, IT HAS BEEN DETERMINED THAT:
The patentability of claims 2, 4-9, 11-14, 16-17, 26-28 and 32 is confirmed.
Claims 1, 3, 10, 15, 18-25 and 29-31 are cancelled.
New claims 33-47 are added and determined to be patentable.
2. The method of claim 1, wherein:
the first filter and the fourth filter comprise a first common filter, and
the second filter and the third filter comprise a second common filter.
[ 33. The method of claim 2, wherein:
a wearable head device comprises the audio system and further comprises a display configured to present a view of a virtual environment; and
the input signal corresponds to an audio asset associated with a location in the virtual environment.]
[ 34. The method of claim 2, wherein:
presenting the first output signal comprises presenting an output of a virtual speaker array comprising a plurality of virtual speakers; and
the virtual speaker array comprises the first filter, the second filter, the third filter, and the fourth filter.]
[ 35. The method of claim 34, further comprising:
applying the input signal to an amplitude panning module; and
applying an output of the amplitude panning module as an input to the virtual speaker array.]
[ 36. The method of claim 11, wherein:
the wearable head device comprises the audio system;
the wearable head device further comprises a display configured to present a view of a virtual environment; and
the input signal corresponds to an audio asset associated with a location in the virtual environment.]
[ 37. The method of claim 11, wherein:
presenting the first output signal comprises presenting an output of a virtual speaker array comprising a plurality of virtual speakers; and
the virtual speaker array comprises the first filter, the second filter, the third filter, and the fourth filter.]
[ 38. The method of claim 37, further comprising:
applying the input signal to an amplitude panning module; and
applying an output of the amplitude panning module as an input to the virtual speaker array.]
[ 39. The method of claim 16, wherein:
a wearable head device comprises the audio system and further comprises a display configured to present a view of a virtual environment; and
the input signal corresponds to an audio asset associated with a location in the virtual environment.]
[ 40. The method of claim 16, wherein:
presenting the first output signal comprises presenting an output of a virtual speaker array comprising a plurality of virtual speakers; and
the virtual speaker array comprises the first filter, the second filter, the third filter, and the fourth filter.]
[ 41. The method of claim 40, further comprising:
applying the input signal to an amplitude panning module; and
applying an output of the amplitude panning module as an input to the virtual speaker array.]
[ 42. The system of claim 26, wherein:
the wearable head device comprises a display configured to present a view of a virtual environment; and
the input signal corresponds to an audio asset associated with a location in the virtual environment.]
[ 43. The system of claim 26, wherein:
presenting the first output signal comprises presenting an output of a virtual speaker array comprising a plurality of virtual speakers; and
the virtual speaker array comprises the first filter, the second filter, the third filter, and the fourth filter.]
[ 44. The system of claim 43, wherein the method further comprises:
applying the input signal to an amplitude panning module; and
applying an output of the amplitude panning module as an input to the virtual speaker array.]
[ 45. The system of claim 32, wherein:
the wearable head device comprises a display configured to present a view of a virtual environment; and
the input signal corresponds to an audio asset associated with a location in the virtual environment.]
[ 46. The system of claim 32, wherein:
presenting the first output signal comprises presenting an output of a virtual speaker array comprising a plurality of virtual speakers; and
the virtual speaker array comprises the first filter, the second filter, the third filter, and the fourth filter.]
[ 47. The system of claim 46, wherein the method further comprises:
applying the input signal to an amplitude panning module; and
applying an output of the amplitude panning module as an input to the virtual speaker array.]
