Three dimensional audio telephony |
摘要 |
A method for creating spatially resolved audio signals for a listener (18) that are representative of one or more callers (12, 14, 16). A digital data signal (13) that represents the individual caller's voice (12) contains an embedded tag (24) that is identifiable with the individual caller. The digital data signal is transmitted from a sending device at the caller's location to a receiving device (30) at the listener's location. At the listener's receiving device, the tag is used to associate each of the digital data signals with a head related transfer functions (32) that are resident in the receiving device by consulting a lookup table. The digital data streams are then convolved (34) with the associated head related transfer function to form binaural digital signals, which are ported to two or more acoustic transducers (36) to create analog audio signals that appear to emanate from different spatial locations around the listener.
