Spatial Audio Reproduction: Towards Individualized Binaural Sound
INTRODUCTION The compact disc (CD) format records audio with 16-bit resolution at a sampling rate of 44.1 kHz. This format was engineered to reproduce audio with fidelity exceeding the limits of human perception, and it works. However, sound is inherently a spatial perception. We perceive the direction, distance, and size of sound sources. Accurate reproduction of the spatial properties of soun...
متن کاملSpatial Sound Reproduction with Wave Field Synthesis
Stereophonic spatial sound reproduction systems with two, five, or more channels are designed for a certain listener position and work well in its vicinity, the so called sweet spot. For listeners at other positions, the quality of the spatial reproduction may be degraded. This contribution describes an advanced spatial reproduction technique called wave field synthesis. It is based on a physic...
متن کاملSound Field Reproduction Employing Non-Omnidirectional Loudspeakers
In this paper we treat sound field reproduction via circular distributions of loudspeakers. The general formulation of the approach has been recently published by the authors. In this contribution, we concentrate on the employment of secondary sources (i.e. loudspeakers) whose spatio-temporal transfer function is not omnidirectional. The presented approach allows to treat each spatial mode of t...
متن کاملObjective evaluation of a three-dimensional sound field reproduction system
We present the results of an empirical evaluation of a three-dimensional sound field reproduction system consisting of 32 loudspeakers installed in a hemi-anechoic room at the University of Sydney. This loudspeaker arrangement allows up to third-order, two-dimensional, and fourth-order, three-dimensional Higher Order Ambisonic (HOA) reproduction of sound fields. The ability of this system to re...
متن کاملVirtual Reality System with Integrated Sound Field Simulation and Reproduction
A real-time audio rendering system is introduced which combines a full room-specific simulation, dynamic crosstalk cancellation, and multitrack binaural synthesis for virtual acoustical imaging. The system is applicable for any room shape (normal, long, flat, coupled), independent of the a priori assumption of a diffuse sound field. This provides the possibility of simulating indoor or outdoor ...
