Convention Paper

Spatial Definition and the PanAmbiophone Microphone Array for 2D Surround & 3D Fully Periphonic Recording

Authors: Miller III, Robert (Robin)

AES Convention 117 · Paper 6253 · October 2004

Abstract

Higher sampling rates are necessary for high spectral resolution, but it is higher angular resolution and precision that preserves source directionality, and therefore higher tonal/timbral quality of that source, termed spatial definition. In acoustic spaces that are extensions of musical instruments, voices, and sources of sound effects (for movies, virtual reality, training simulation), tonality is a major contributor to lifelike perception - but in audio reproduction, lifelike tonality is limited by the recording system. A surround microphone has been developed both for more precise 2D surround ("PanAmbio"), compatible with ITU 5.1 and stereo, and for "PerAmbio" 3D (with height) for the ultimate in tonal reality distributable using ordinary 6-channel media for either decoderless 2D replay or 3D with decoder and five additional speakers.
