Nice library. The landing page needs some more work. The "features" section contains just keywords that are not explained. I'd like a sentence explaining each feature: what it does and when/why it is useful. For example, at first I didn't understand what "Auto Mute" meant. That was until I played a sound while I switched to another tab, which made the sound stop. When would one want to use auto mute? To me it felt unnatural/unwanted, almost like a bug. Explain why Web Audio API is used when available. What will not work (if applicable) when using the HTML5 Audio fallback? In what kind of web applications would I want to use Waud.js? Games?
