Abstract
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.
