US 10,419,870 B1 · Applying audio technologies for the interactive gaming environment

Abstract

Personalized HRTFs for each of plural computer game participants are convolved with functions representing the acoustics of a physical room in which each participant is located or representing the acoustics of a virtual space in the game environment. Head-tracking of each participant may be employed as the game is played and the HRTFs established accordingly. As the game progresses, the location of each player's character within the virtual game space with respect to the other players is tracked and audio adjusted accordingly. If desired, audio can be down-mixed from, e.g., 5.1 audio and then up-rendered for each player by the game console or by the players' local game interface, e.g., a computer game head-worn visor assembly.

Claims21

Dependent claims

A device comprising:

at least one computer medium that is not a transitory signal and that comprises instructions executable by at least one processor to:
access at least a first set of head related transfer functions (HRTF) each HRTF being associated with a pose, the first set of HRTF comprising plural finite impulse response (FIR) filters, each of which includes plural taps, with at least some of the plural taps being associated with a respective coefficient;
identify a first HRTF of the first set of HRTF based at least in part on a pose of a body;
concatenate the first HRTF with a HRTF associated with a space to render a concatenated HRTF;
convolute the audio stream using the concatenated HRTF to render a first adjusted stream;
and
provide the first adjusted stream to at least one audio speaker of a first playback device.

4 more elements

A system comprising:

at least one computerized first playback device having at least one audio speaker;
and
at least one computer medium that is not a transitory signal and that comprises instructions executable by at least one processor to:
access at least a first set of head related transfer functions (HRTF) tailored to a first person, each HRTF being associated with a pose of the first person, the first set of HRTF comprising plural finite impulse response (FIR) filters, each of which includes plural taps, with each tap being associated with a respective coefficient;
identify a pose of the first person;
identify a first HRTF of the first set of HRTF based at least in part on the identification of the pose of the first person;
combine the first HRTF with a HRTF associated with a space to render a combined HRTF;
convolute the audio stream using the combined HRTF to render a first adjusted stream;
and
provide the first adjusted stream to the at least one audio speaker of the first playback device.
