Abstract
An audio processing system may modify an input surround sound signal to generate a spatially equilibrated output surround sound signal that is perceived by a user as spatially constant for different sound pressures of the surround sound signal. The audio processing system may determine based on a psychoacoustic model of human hearing, a loudness and a localization for a combined sound signal. The loudness and the localization may be determined by the system for a virtual user located between the front and the rear loudspeakers that has a predetermined head position in which one ear of the virtual user is directed towards one of front or rear loudspeakers and the other ear of the virtual user being directed towards the other of the front or rear loudspeakers. The audio processing system may adapt the front and/or rear audio signal channels based on the determined loudness and localization.
