d3-audio-spectrum's Issues

Please fix index.html

Modern d3.js contains some utf characters, and your code causes syntax error. Please add following line to index.html

p.s. Web audio input seems to be broken, it doesn't work in chrome 45.0.2454.26 beta-m nor in canary. And I was not able to find about:flags in the URL bar, and then enable Web Audio Input flag.
