This is insanely cool.

Awesome examples. It would be nice to get support for formats besides WAV, but that's future work. Is MP3 decoding proprietary, or just encoding?

Afaik both encoding and decoding require a license. However there is a mutual agreement from patent holders that there is no license required for FOSS decoders, allowing things like VLC to function without a license.

To expand a bit: mp3 decoding in JavaScript has been done, and it works pretty well, but not perfectly / not on all files. I've used it and stuff derived from it with quite satisfactory results in situations where I can control all of the inputs it will be used with. Adding basic support for mp3 decoding to this could be just a matter of integrating JSMad, if that's the way they felt like going about it, but adding really robust, efficient, gonna work all the time support would require a significant investment of additional effort.

I don't know what the state of the art is for mp3 encoding in JavaScript, if there is one.

This is super cool! Is HTML5 audio in a pretty decent state at this point as far as reliability?

Wow, I'm seriously impressed.

I'm inspired to make a game using this library I think!

Excellent. I will definitely use this. In fact, I'm commenting largely to bookmark this.

HN is the only place I know that downvotes for ignorance. Is my comment really more irritating than the other comments that are one-word compliments?

I was thrilled when Flash had sound api quite a long time ago.

I'm now much more thrilled to see this. A lot of nerdy people will publish free open source synthesizer over the next few years.

We need javascript plugin interface like VST.

This is what happens when your programming language does not let you specialize math operations, or you lack a decent macro system.

Not necessarily. You could write nice libraries utilizing the object notation and method chaining, just look at jQuery.
