AW: First Squawks

[Ian Fritz]

Jeffry --

The classic reference for simple 1D physical modeling is the following
review article:

ME McIntyre, RT Schumacher and J Woodhouse, "On the oscillations of
musical instruments", J. Acoustic Soc. Am., vol. 74, p. 1325 (1983)

Simplified digital implementations were developed at Stanford by JO
Smith. See for example:

JO Smith, "Musical applications of digital waveguides", Stanford
Department of Music Report No. STAN-M-39. 

There is also a tutorial on the Stanford CCRMA web site.

You can also learn a lot from the many Yamaha patents and the VL1
programmers' guide.

I've heard rumors of somebody else doing an analog implementation but I
don't know the details.

Your comments about modeling the control interface and exploring all the
combinations of model parameters are 100% correct. These factors don't
worry me because I'm interested in exploring new sounds rather than in
realistic immitation. Also I use a wind controller, so the interfacing
should be more natural than with a keyboard.

At least your model of the Titanic worked.
