In the future as constraints on frequency range and dynamic range reach the full capacity of human hearing, attention will turn to increasing the number of audio channels. How best to use the capacity delivered by new media is the subject of this talk. Three factors dominate the placement of more channels than the standard 5.1: the reproduction of physical acoustics of rooms, psychoacoustics, and desires of artists. This talk will examine these three areas. In addition recording, mixing, and sound system development for a larger number of channels will be described. The first 10.2 channel systems have been installed in stereo dealers and cinemas. Some of the experience of making program material for this wide range of venues will be described.
