Abstract
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.
