Patent ID: 8050434

Claim:
A system for processing audio signals, the system comprising: left and right front audio signals each comprising information about a front spatial position of a sound source relative to a listener; left and right rear audio signals each comprising information about a rear spatial position of a sound source relative to a listener; a dialog clarity module configured to enhance dialog in at least one of (a) the left and right front audio signals and (b) a center front audio signal; at least one front perspective filter configured to filter each of the left and right front audio signals to yield filtered left and right front output signals, wherein the left and right front output signals are each configured to drive a front speaker; at least one rear perspective filter configured to filter each of the left and right rear audio signals to yield left and right rear output signals, wherein the left and right rear output signals are each configured to drive a rear speaker to simulate a rear surround sound effect when positioned facing a listener; and a bass management module configured to: enhance a bass response associated with at least the filtered left and right front output signals; and selectively apply crossover filters to one or more of the filtered left and right front output signals and the filtered left and right rear output signals.
