"Analysis and Synthesis of the Chinese Souna"

By

Mr. Po-Hei Wong


Abstract

The spectral properties of the Chinese Souna, an instruments with history
of around 2000 years, are considered. Additive Synthesis is the simplest
and purest synthesis technique of modeling based on the summation of sine
wave but this technique requires data storage and long computation time to
adequately synthesize the tone. A modified Douglas-Puecker line
simplification algorithm was introduced, with a 87% data reduction. Also,
we further our study on data reduction by using group additive synthesis.
Two models of choosing the envelope to represent the group were
introduced. A Csound implementation for synthesizing the Chinese souna
tones has been developed. Listening tests showed that the weighted model
is the best in comparison with the other models.
