摘要： A three-dimensional sound generation system includes one or more processors of a computing device, including capability to receive sound tracks, each of the sound tracks comprising one or more sound sources, each of the one or more sound sources corresponding to one or more respective sound categories, receive or determine a first configuration in a three-dimensional space, the first configuration comprising a listener position and a computing device location relative to the listener position, determine a second configuration comprising a change to at least one of the listener location or the computing device location relative to the listener position, generate, using the one or more sound tracks and the second configuration, one or more channels of sound signals, and provide the one or more channels of sound signals to drive one or more sound generation devices to generate a three-dimensional sound field.

摘要： A sound generation system and related method include a user interface device and a processing device to obtain a specification of a three-dimensional space, obtain one or more sound tracks each comprising a corresponding sound signal associated with a corresponding sound source, present, in a user interface, representations representing one or more listeners and the one or more sound sources corresponding to the one or more sound signals in the three-dimensional space, responsive to a configuration of the locations of the one or more listeners or the locations of the one or more sound sources in the three-dimensional space in the user interface, determine filters based on the configuration and pre-determined locations of one or more loudspeakers, and apply the filters to the one or more sound signals to generate filtered sound signals for driving the one or more loudspeakers.

摘要： A specification of a mesh of filters may be defined on a grid in a three-dimensional space presented in a user interface. A plurality of sound tracks may be determined, wherein each of the sound tracks is associated with a corresponding sound source that may be represented in the three-dimensional space along with a listener. Responsive to user configuration of a position of the listener and/or positions of the sound sources in the three-dimensional space, a plurality of filters may be selected based on the mesh of filters and the positions of the sound sources and the listener in the three-dimensional space. Each of the filters may be applied to a corresponding one of the plurality of sound tracks to generate a plurality of filtered sound tracks and the three-dimensional sound may be generated based on the plurality of filtered sound tracks.
