Abstract

An audio rendering system and method are disclosed. The audio rendering system generally comprises front and rear signal modifiers configured to receive a plurality of audio signals representing a plurality of sources of aural information and location information representing apparent location for the source of said aural information. A gain is applied to the signals representative of the location information. A front signal modifier includes a plurality of head-related transfer functions filters and a rear signal modifier includes a plurality of filters configured to approximate head-related transfer function filters. The system further includes front speakers comprising a left front speaker and right front speaker configured to receive signals from the front signal modifier and generate a signal to a listener. At least one rear speaker is configured to receive signals from the rear signal modifier and generate a signal to the listener to offset frontward bias created by the front speakers. The gains applied to the signal are calculated to produce generally equal perceived energy from each of the front and rear speakers.
