ABSTRACT:
A method for processing audio signals can include receiving left and right front audio signals, where the left and right front audio signals including information about front spatial position of sound sources relative to a listener. The method can also include receiving left and right rear audio signals, where the left and right rear audio signals include information about rear spatial position of sound sources relative to a listener. In addition, the method can include applying at least one front perspective filter to each of the left and right front audio signals to yield filtered left and right front output signals, where the left and right front output signals each drive a front speaker. Moreover, the method can include 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, where the left and right rear output signals each drive a rear speaker to simulate a rear surround sound effect when positioned in front of a listener.
