Abstract

Audio windowing is a front-end, or user interface, to an audio system with a spatial sound backend. Besides the directionalization of the DSP spatialization, gain adjustment is used to control the volume of the various sources. Virtual gain can be synthesized from components derived from iconic size, distance, orientation, and directivity, and selectivity enabled according to room-wise partitioning of sources across sinks. The authors describe the mathematical derivation of the calculation of virtual gain, and outlines the deployment of these calculations in an audio windowing system.<>
