Towards a Rational Basis for Multichannel Music Recording

The DVD-Audio standard will include multichannel uncompressed PCM audio. Although we have 30 (or more) years of experience with recording, mixing, and reproducing stereo, as an industry we have relatively little experience with multichannel music recordings for the home. In this paper, we have chosen to optimize perceptual aspects of spatialization. This leads to a mathematical basis for pan matrices, microphone placement, and for speaker placement correction. Much of this basis can be considered to be an extension of the sound-field work pioneered by Michael Gerzon. Recordings were done using simultaneous, multiple experimental microphone techniques so that different methods could be easily compared. Results of these experiments are described.
