/*! \class SingWave
|
|
\brief STK "singing" looped soundfile class.
|
|
|
|
This class contains all that is needed to make
|
|
a pitched musical sound, like a simple voice
|
|
or violin. In general, it will not be used
|
|
alone because of munchkinification effects
|
|
from pitch shifting. It will be used as an
|
|
excitation source for other instruments.
|
|
|
|
by Perry R. Cook and Gary P. Scavone, 1995 - 2002.
