Abstract:
1. A method for processing audio signals, the method comprising: receiving left and right front audio signals, the left and right front audio signals each comprising information about a front spatial position of a sound source relative to a listener; receiving left and right rear audio signals, the left and right rear audio signals each comprising information about a rear spatial position of a sound source relative to a listener; applying one or more definition filters to the filtered left and right front output signals to enhance the left and right front input signals, the one or more definition filters comprising a high-pass shelving filter configured to produce left and right front output signals; providing the left and right front output signals to first front speakers; applying at least one rear perspective filter to each of the left and right rear audio signals to yield left and right rear output signals; and applying the left and right rear output signals to second front speakers, wherein the left and right rear output signals are each configured to drive one of the second front speakers to simulate a rear surround sound effect.
