Spatial Audio Coding Based on Universal Spatial Cues

Creative Technology Ltd.

A patent family: one line of work, grouped by real continuity rather than by a technology label inferred from titles. 8 of these applications claim priority to application 60/747,532, filed May 17, 2006. A shared origin can cover several different claimed inventions, which is why members here may not share a title. In-force patents first, soonest term end first, then patent number. Expired patents follow, in the same order.
