Claim:
1. A system for reproducing an acoustic scene for a listener comprising: a computing device configured to process a sound recording of the acoustic scene using a spherical harmonic representation of a head-related transfer function, wherein the head-related transfer function is interpolated into a spherical sampling grid offline and not in real-time, and a beamformer equation, wherein both the head-related transfer function and the beamformer equation are combined to produce a binaurally rendered acoustic scene for the listener, wherein the binaurally rendered acoustic scene is produced for any head position of the listener before the head position of the listener is known, and rotation is applied to the acoustic scene, such that the scene is configured to rotate in the opposite direction of a head of the user, and wherein motion of a sound source is captured in the sound source's plane-wave decomposition; a position sensor configured to collect motion and position data for a head of the user and also configured to transmit said motion and position data to the computing device; a sound delivery device configured to receive the binaurally rendered acoustic scene from the computing device and configured to transmit the binaurally rendered acoustic scene to a left ear and a right ear of the listener; and wherein the computing device is further configured to utilize the motion and position data from the inertial motion sensor in order to process the sound recording of the acoustic scene with respect to the motion and position of the user's head.
