[sdiy] freq. deviations

[Ian Fritz]

Hi Folks --

Here are two references on measured frequency deviations in acoustic 
instruments:

R. T. Schumaker, Analysis of aperiodicities in nearly periodic waveforms, 
J. Acoust. Soc. Am., vol. 91, p. 438, 1992

T. D. Wilson, Characterizing the clarinet tone: Measurements of Lyapunov 
exponents, correlation dimension, and unsteadiness, J. Acoust. Soc. Am., 
vol. 104, p. 550, 1998

Hope you have a good computer!
