The documentation cautions you to "make sure to check if the user's browser supports all of it (1, 2, 3) before you start recording." All of it being "getUserMedia, Web Workers and the Web Audio API."

Surprisingly, it DOES look like getUserMedia is supported by Android browser and Android Chrome now (with some weird namespace prefix/object).

Still doesn't work on anything iOS though (until Apple puts it in Safari).

So no dice for HTML5 on mobile still (I've been waiting since 2012 for some way to support in-browser web-based audio recording, sigh). :|
