|
Banded waveguide modeling class.
|
|
<p>
|
|
This class uses banded waveguide techniques to model a variety of sounds, including bowed bars, glasses, and bowls. For more information, see Essl, G. and Cook, P. "Banded Waveguides: Towards Physical Modelling of Bar Percussion Instruments", Proceedings of the 1999 International Computer Music Conference.<p>
