ABSTRACT
A parametric synthesis model for wind chimes is presented. 
A physics-based stochastic process is used to  
trigger a modal sound-production model for the tubes   
of a wind chime. Mode parameters are extracted in a    
semiautomatic fashion from a sound sample. An example and 
some possible applications are presented.
