Waveform.JS

Waveform.JS makes drawing SoundCloud waveforms simple and lets you style and color them the way you want. It comes as a small JavaScript library and is using a lightweight service hosted on waveformjs.org that translates the waveform image provided by SoundCloud into an array of floating points.
