Virtual reality, augmented reality, and mixed reality systems with spatialized audio

A spatialized audio system, comprising:

• a sensor to detect head pose of a listener;
• and
• a processor to:
• render, based on the detected head pose of the listener, first audio data corresponding to a first plurality of sources, each of the first plurality of sources having respective ones of a first plurality of positions, to second audio data corresponding to a second plurality of sources, each of the second plurality of sources having respective ones of a second plurality of positions;
• and
• reproduce, based on the second audio data, a spatialized sound field corresponding to the first audio data for the listener,
• wherein the first plurality of sources are virtual sound sources,
• wherein the second plurality of sources are virtual sound sources and consists of fewer sources than the first plurality of sources, and
• wherein rendering the first audio data to the second audio data comprises each of the second plurality of sources recording virtual sound generated by the first plurality of sources at a respective one of the second plurality of positions.
