/*! \class ReedTable
|
|
\brief STK reed table class.
|
|
|
|
This class implements a simple one breakpoint,
|
|
non-linear reed function, as described by
|
|
Smith (1986). This function is based on a
|
|
memoryless non-linear spring model of the reed
|
|
(the reed mass is ignored) which saturates when
|
|
the reed collides with the mouthpiece facing.
|
|
|
|
See McIntyre, Schumacher, & Woodhouse (1983),
|
|
Smith (1986), Hirschman, Cook, Scavone, and
|
|
others for more information.
|
|
|
|
by Perry R. Cook and Gary P. Scavone, 1995 - 2005.
