I'm looking for some physics sound libraries, one or many (depends upon diversity). I haven't been in the market for sound libraries in a long time, and I really need to update. I was wondering if anyone had any recommendations on sound libraries of physics sounds. I'm particularly interested in impact sounds and continuous contacts (rolling, sliding etc.) between objects of different sizes/materials. Not particularly interested in breaking, fracturing, aggregate materials (e.g. footsteps on gravel).
Thanks for your help!
