Compression and Decompression of Wavetable Synthesis Data

Table look-up (or wavetable) synthesis methods have been widely used for many years in music synthesizers. Recently wavetable music synthesis has received new interest in the context of mobile applications such as personalized ring tones and pager notification signals. The limited amount of storage and processing available in such mobile devices makes the use of compressed wavetable data desirable. In this paper several issues related to wavetable compression are described and an efficient compression/decompression method is proposed for reducing the size of wavetable data while maintaining loop continuity and timbral quality.
