The DVD-Video 1.0 standard allow a disc that has little or no video on it, but can carry multiple channels of PCM audio. This allows us to provide an enhanced spatial experience by using more channels than the traditional stereo recording. We propose a number of new processes that may be incorporated into the production chain, from microphone design through improved pan matrices to corrections in the home for loudspeaker placement. These new processes start to take advantage of the possibilities of the format. We suggest that the analytic framework of spatial harmonics can provide a rational way to unify and evaluate choices at each stage of the process.
