decoding AIF url from Parse.com in Chrome using javascript

Parse.com supplies me with a url for a .aif audio file. Obviously, if I use an audio tag playback doesn't work in Chrome, since .aif isn't supported in Chrome. So I thought about using aurora.js: http://ift.tt/1zzadlv but that bad boy uses XMLhttprequest, and I'm requesting from a different domain so that doesn't work because it violates the same-origin policy. What should I do?
