Patent ID: 7167567

Claim:
A method of providing localization cues to a source audio signal to perceive a sound source at a selected direction and a selected near field distance less than or equal to about 1.5 m from a listener's head based on a head related transfer function (HRTF) pair determined for the sound source located at the selected direction and a reference distance at a larger distance from the listener's head than the selected near field distance, the method comprising: providing a two channel audio signal from the source audio signal; spectrally shaping the two channel audio signal based on the HRTF pair; introducing a time delay between the channels of the two channel audio signal based on an interaural time delay associated with the selected direction; and applying a different gain factor to each of the two channels, wherein the different gain factors are determined based on the selected direction and the selected near field distance from the listener's head.
