Virtual spatial sound scape

摘要

An apparatus, method and computer program product relating to spatialized audio. There is a set of headphones having an accelerometer and a tilt sensor for tracking the location and orientation of the set of headphones and a computer apparatus which includes a headphone position processor to receive headphone location and orientation information from the set of headphones, virtual speaker location processors (VSLPs) which receive a digital signal containing audio information from a digital audio stream and a digital signal containing headphone location and orientation information from the headphone position processor and output a digital signal containing audio information, a summing processor to receive the digital output signals from the VSLPs, sum them and output them to a digital to analog (D/A) converter. The D/A converter converts the summed digital output signals received from the VSLPs to an analog signal and outputs the analog signal to the set of headphones.
