A Vector Quantization-Based Compression Scheme for Wave Field Synthesis Source Signals

Document Thumbnail

This paper introduces a lossy data compression scheme of the signals used for the synthesis of narrow-band virtual point wavefields. The fields are synthesized by a set of distributed point wave sources at fixed locations inside a wave medium. The data compression scheme is implemented using vector quantization. An application example referring the synthesis of a virtual point field, using three point sources, is considered. Its performance is assessed by de ning and calculating a mean distortion measure, for di erent number of quantization levels. Extension to the synthesis of broad-band wave fields of arbitrary shape is straightforward.
