Safari can't load audio - XHR (example included) #66

Hi @diurnalist, I'm following up on the updates to issue #27 - 'Can't play sound in Safari OSX'.

Safari is still unable to load SoundCloud audio into a buffer. I've create a simple example here to show you. The example gets 10 tracks. Click one of the songs to load it into an audioBuffer using Tone.js and it should begin playing.

Example: https://lukephills.github.io/soundcloud-api-audio-buffer/
Source Code: https://github.com/lukephills/soundcloud-api-audio-buffer/

It works as expected in Chrome, but Safari and iOS can't load the track and throw a 403 error and Request header field Accept-Encoding is not allowed by Access-Control-Allow-Headers. error.

Interestingly though, running my example locally in Safari works.

Please can you look it into this soon. My project Blokdust relies on Soundcloud working in Safari. I really appreciate your time and effort.
