STK clarinet physical model class.
This class implements a simple clarinet physical model, as discussed by Smith (1986), McIntyre, Schumacher, Woodhouse (1983), and others.
This is a digital waveguide model, making its use possibly subject to patents held by Stanford University, Yamaha, and others.

stk::Clarinet::Clarinet | ( | StkFloat | lowestFrequency = 8.0 |
) |
Class constructor, taking the lowest desired playing frequency.
An StkError will be thrown if the rawwave path is incorrectly set.
Fill a channel of the StkFrames object with computed outputs.
The channel
argument must be less than the number of channels in the StkFrames argument (the first channel is specified by 0). However, range checking is only performed if _STK_DEBUG_ is defined during compilation, in which case an out-of-range value will trigger an StkError exception.
Implements stk::Instrmnt.
