Really interesting what happens to the sound when you switch tabs (in Chrome at least): The sounds still play, but slowed down about 10x.

it is because chrome slows main thread js execution for inactive tabs. The solution is to do your scheduling (setInterval etc) in a web worker.

Yeah, that's a common Web Audio hassle. On mobile it gets even crazier, although I haven't tried this site in mobile.

For me, in Firefox on Yosemite, the slowdowns seem to come at random, even when the tab is in focus.

A workaround is to detach the tab and keep it visible. Then it doesn't need to be focused.
