Using HTML5 Audio as a p5.sound input

[benjaminleonard]

I'm not sure it warrants creating another example since it's not that complicated to set up but I thought I'd mention it since it took me a while to figure out that it was possible to use a HTML5 source as an input aka:

audio = p.select('#audio');
analyzer = new p5.Amplitude();
analyzer.setInput(audio);

It's especially useful in cases like mine where a file is too large to work well with loadSound().

Perhaps a note in the setInput reference page?
