DownloadHelper Source

Did some music streaming DRM work once upon a time. The goal I was given was to get the music to play in the browser using the Web Audio API without the DownloadHelper extension being able to download the track to the user's computer as an .mp3 file. The extension's source code was quite obfucated – I think maybe deliberately, to fuck with people like me trying to break it for The Man – so I ended up having to print it out and debug it the old fashioned way with a red pen.
