test_clusters.sound_group

This folder contains Georges sheets that link sound group defined in 
the cluster system (edited in 3DS Max) to a sound sheet.
	
This allow to put sound inside the cluster systems.

Each sheet can contains any number of association. 
It is a good practice to merge into a single sheet all
the sound groups/sound sheets thet belong the the
same building.
