I have tried to find some material on this, but come up with little.
The basic suggestion for one glass shard hitting a surface is to use FM to achieve the inharmonic sound. But especially with larger glass shards or pitched down recordings there is a noticeable modulation effect like property as well.
Is there perhaps any practical work on this somewhere? Perhaps working on physical modelling or a usable signal modelling?
Any pointers are welcome.
Thanks and best wishes,
