it sounds your processor can't keep up with your sound buffer. you can start Google chrome up with --audio-buffer-size=2048 to increase it All audio technologies have buffer issues, it's a pretty basic problem. it's not unique to web audio.
Nope, that's not it, makes no difference. Saying that all audio technologies have issues is a dodge. Technology is hard, software is about dealing with problems not about passing the buck and saying "sorry it sucks, it's hard and I gave up". Computer audio isn't exactly rocket science, tons of products get it right, browser makers just can't be bothered to invest in it.
Ironic, in the context of this article.
