The system and method of the present invention provides enhanced surround
sound effects. In one embodiment, 90.degree. phase shift and copy of the
modified head related transfer functions (HRTF) are applied to each rear
sound signal. The modified HRTF for each rear signal is generated by
removing the head related transfer function corresponding to the front
center signal from the HRTF corresponding to the rear sound signal. This
provides the audible effect of distinguishing more clearly sounds
originating in front of the listener or to the rear of the listener while
not limiting the perceived bandwidth of the signal. The rear signals
corresponding to the first channel are inverted. The front and rear
signals for each corresponding channel are then combined. The two
channels, generated can be stored on media, such as film, and subsequently
read and input to a surround sound decoder to generate enhanced surround
sound output.
