 [Here's a working demo] (http://www.michaelbromley.co.uk/experiments/soundcloud-vis/#muse/undisclosed-desires). Enjoy and share!
 
+**Update May 2015** - As of latest versions of Chrome (42+) and recent versions of Firefox, changes in the way cross-origin audio is handled mean this demo may not work. It's a well-known issue for everyone who's used the SoundCloud API for JavaScript visualizations (there are a lot of us).

+Basically, the CORS headers are set inconsistently by the various CDN servers used by Soundcloud. This means that some tracks will work, and some tracks will fail to play altogether :(
