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 desira...
متن کاملOptimized Multiple Wavetable Interpolation
One effective approach to music analysis/synthesis is multiple wavetable interpolation, which matches an audio signal at selected breakpoints by determining weightings for several wavetables; the sound is resynthesized using multiple wavetable additive synthesis by interpolating between the weightings for each wavetable at consecutive breakpoints. This article presents a new breakpoint-matching...
متن کاملHigher Order Integrated Wavetable Synthesis
Wavetable synthesis is a popular sound synthesis method enabling the efficient creation of musical sounds. Using sample rate conversion techniques, arbitrary musical pitches can be generated from one wavetable or from a small set of wavetables: downsampling is used for raising the pitch and upsampling for lowering it. A challenge when changing the pitch of a sampled waveform is to avoid disturb...
متن کاملPerceptual Wavetable Matching for Synthesis of Musical Instrument Tones
Recent parameter matching methods for multiple wavetable synthesis have used a simple relative spectral error formula to measure how accurately the synthetic spectrum matches an original spectrum [1]. It is supposed that the smaller the spectral error, the better the match, but this is not always true. This paper describes a modified error formula, which takes into account the masking character...
متن کاملWavetable Synthesis Strategies for Mobile Devices*
Table look-up (or fixed-wavetable) music synthesis has recently received new interest in the context of mobile applications such as personalized ring tones and pager notification signals: the market for consumers purchasing polyphonic ring tones exceeded US $4 billion worldwide in 2004. Table look-up (or fixed-wavetable) synthesis methods have been widely used for many years in music synthesize...
