Abstract
A spatialized audio system includes a sensor to detect a head pose of a listener. The system also includes a processor to render audio data in first and second stages. The first stage includes rendering first audio data corresponding to a first plurality of sources to second audio data corresponding to a second plurality of sources. The second stage includes rendering the second audio data corresponding to the second plurality of sources to third audio data corresponding to a third plurality of sources based on the detected head pose of the listener. The second plurality of sources consists of fewer sources than the first plurality of sources.
