Abstract

A new method is presented for capturing, recording, and reproducing spatial sound that provides a vivid sense of realism. The method generalizes binaural recording, preserving the information needed for dynamic head-motion cues. These dynamic cues greatly reduce the need for customization to the listener. During either capture or recording, the sound field in the vicinity of the head is sampled with a microphone array. During reproduction, a head tracker is used to determine the microphones that are closest to the positions of the listener's ears. Interpolation procedures are used to produce the headphone signals. The properties of different methods for interpolating the microphone signals are presented and analyzed.
