Abstract (en)

[origin: WO9410815A1] A method for producing three-dimensional sound associated with an object that is moving from a first position (P1) to a second position (P2) with respect to the listener (10). The method includes the effects of doppler shifting, head shadowing, distance on frequency components of the sound as well as the volume of the sound, and the natural sensitivity of the human ear in the 7-8 kHz range. The method provides a sequence of digital sound samples which when converted into analog waveforms and for production of audio signals will provide an audio signal which will provide sound queues to the listener for the location of the sound in three-dimensional space.
