  • Control of audio effects using volumetric data
    Patent number: 10293259
    Abstract: One example method for processing sound in a computer environment includes recognizing a location of a listener in the computer environment, identifying a shape matrix including, for each of a plurality of vectors intersecting the location of the listener, a distance from the location of the listener to an environmental boundary of the computer environment along the vector, selecting an audio filter based on the shape matrix, and outputting sound filtered by the audio filter.
    Type: Grant

  • Redirecting audio output
    Patent number: 10045144
    Abstract: A method for providing directional audio in a computer environment includes recognizing a location of a listener in the computer environment, recognizing a location of a sound emitter in the computer environment, and recognizing a plurality of candidate portal points in the computer environment. Each candidate portal point provides a viable audio path from the location of the sound emitter to the location of the listener. The method further includes identifying a selected portal point from among the plurality of candidate portal points based at least on a first distance from the selected portal point to the location of the listener and a second distance from the selected portal point to the location of the sound emitter and setting a perceived direction of the sound emitter to go through a location of the selected portal point.
