SYSTEMS AND METHODS FOR PROVIDING IMMERSIVE AUDIO EXPERIENCES IN COMPUTER-GENERATED VIRTUAL ENVIRONMENTS

摘要

Described herein are systems and method for providing an immersive audio experience in a computer-generated virtual environment. An audio-mixer is placed at a location in a domain of the virtual environment and receives a separate audio feed from each of the audio source nodes directly connected to the audio-mixer. The audio-mixer mixes the received audio feeds in dependence on corresponding location, position and intrinsic loudness information to generate a separate spatialized mixed audio feed for each of the directly connected audio listener nodes. The audio-mixer sends, to each of the audio listener nodes directly connected to the audio-mixer, the separate spatialized mixed audio feed generated for the audio listener. An audio-mixer also receives and sends non-spatialized mixed audio feeds to/from other audio-mixers. The location of the audio-mixer is preferably moved to account for audio source nodes moving and/or changes to which audio source nodes are directly connected to the audio-mixer.

主权项

1. A method for providing an immersive audio experience in a computer-generated virtual environment that includes one or more domains, wherein each of the one or more domains includes at least two audio source nodes and at least two audio listener nodes, the method comprising:
(a) placing at least one audio-mixer in a domain of the virtual environment; (b) at least one said audio-mixer,
(b.1) receiving at a separate audio feed from each of at least two audio source nodes directly connected to the audio-mixer,
wherein each of the audio feeds includes
corresponding location information indicative of a location of the audio source node in the virtual environment,corresponding position information indicative of a position of the audio source node in the virtual environment, andcorresponding intrinsic loudness information indicative of an intensity of sound at the audio source node in the virtual environment;(b.2) mixing the audio feeds received by the audio-mixer, in dependence on the corresponding location, position and intrinsic loudness information, to thereby generate a separate spatialized mixed audio feed for each of the audio listener nodes directly connected to the audio-mixer; and(b.3) sending, to each of the audio listener nodes directly connected to the audio-mixer, the separate spatialized mixed audio feed generated for the audio listener.
