Haxe reinterpretation of the MT5 Web Audio Mixer (https://github.com/squallooo/MT5)
Live demo: https://cdn.rawgit.com/cambiata/HaxeWebAudioMixer/master/bin/index.html
Somewhat stripped down - no node.js server stuff, the song data is hardcoded etc. but the core Web Audio mixing stuff is implemented.
