Currently, multiple sounds playing at the same time peaks the master volume, and a lot of the sound quality gets lost. Find a resource that will show how to manage sound quality.

No file, test, or entry point is named. Start by locating how simultaneous sounds are played and reproduce the master-volume peak with multiple sounds. Research audio mixing approaches, then verify that concurrent sounds no longer clip or lose noticeable quality.
