\brief PhISEM and PhOLIES class.
|
|
|
|
PhISEM (Physically Informed Stochastic Event
|
|
Modeling) is an algorithmic approach for
|
|
simulating collisions of multiple independent
|
|
sound producing objects. This class is a
|
|
meta-model that can simulate a Maraca, Sekere,
|
|
Cabasa, Bamboo Wind Chimes, Water Drops,
|
|
Tambourine, Sleighbells, and a Guiro.
|
|
|
|
PhOLIES (Physically-Oriented Library of
|
|
Imitated Environmental Sounds) is a similar
|
|
approach for the synthesis of environmental
|
|
sounds. This class implements simulations of
|
|
breaking sticks, crunchy snow (or not), a
|
|
wrench, sandpaper, and more.
|
