Practical Implementation of a Data-based Wave Field Reproduction System

摘要

A practical implementation of a 3D audio reproduction system based on Wave Field Synthesis(WFS) will be described. Appropriate techniques and formats for the recording and transmissionof audio and control data are proposed. The basic idea is to transmit measured room impulseresponse sets, together with a distinct number of dry sources, and re-synthesize the acousticalscene at the receiver. Required channel capacity and hardware costs are discussed in detail.Compared with standard discrete loudspeaker surround formats, a real holographic acousticdisplay is achieved, independent of the listener’s position.
