(45 min) Aaron Heller, Eric Benjamin, Richard Lee » Location: Campbell Recital Hall
Implementation of Ambisonic reproduction systems is limited by the number and placement of the loudspeakers. In practice, real-world systems tend to have insufficient loudspeaker coverage above and below the listening position. Because the localization experienced by the listener is a nonlinear function of the loudspeaker signals it is difficult to derive suitable decoders analytically. As an alternative it is possible to derive decoders via a search process in which analytic estimators of the localization quality are evaluated at each search position. We discuss the issues involved and describe a set of tools for generating optimized decoder solutions for irregular loudspeaker arrays and demonstrate those tools with practical examples.

The schedule is a major guideline. There is no guarantee events will take place at the announced timeslot.
