I asked this question over in the Game Dev, but was told I would get a better answer here related to the specifics of the terminology and background behind the issue.
In the Unity game engine, before I managed sounds properly, if too many accumulated at the same it would become this loud drowned out mega sound (like the speakers got blown out). With proper audio management this is never an issue, but it's funny how many times I see this problem come up in professional level games (notably Demon's Souls and Dark Souls when too many collisions happen with breakable boxes triggering too many sounds to happen at once).
Is there a word that describes that drowned out mega sound that happens when too many sounds are being played at once? Also, what's the process that's happening on the audio technical side when this sound is played, meaning are the sounds just being shoved into one mixer or something?
