Reflection functions derived from impulse response estimates as applied to musical instrument tone synthesis
This dissertation introduces methods for extracting synthesis information from the sound sequence of musical instruments where a "sound sequence" is the digital representation of a one-dimensional acoustical pressure function. These methods are based on modern digital signal processing modeling techniques such as auto-regressive modeling. Particular attention is placed on the implementation of the McIntyre-Schumacher-Woodhouse model (J. Acoust. Soc. Am. 74, 1325-1345, 1983) where a non-linear controller and a linear element interact to produce sound. It is shown that the specific characteristics of a musical instrument waveform may be preserved in the synthesized version of the waveform. It is also shown that reflection functions are obtainable from estimates of the impulse response when the estimation is performed on the release transient of certain classes of musical instruments (most notably, air-reed). ^
