Individualization in spatial-audio coding

A novel spatial-audio coding technique that allows individualized 3D audio presentation is described. It exploits the dichotomous roles of the low-frequency interaural timing and level difference cues versus the high-frequency spectral cues in human sound localization. The high-frequency spectral cues are modified to match the acoustics of the listener's outer ears, while preserving the original low-frequency interaural cues. The theory behind the coding technique is described and sound localization data are shown demonstrating the fidelity of the coding technique. Issues relating to the frequency resolution of directional frequency bands are explored.
