As I mentioned last time I’ve been creating a plugin for split-screen audio in Unity. I can demonstrate the basics now, so here’s a video:
The plugin will be sold on the Unity Asset Store once finished, so if you’re interested in testing it or using it for your own games let me know!
Edit:
I uploaded simple a webplayer demonstration for you to check out: http://www.ramjetanvil.com/games/multiaudio_demo/WebPlayer.html
The Beta package is now ready for testing. Again, if you want to participate, contact me through email, or post in the Unity forum thread: http://forum.unity3d.com/threads/165694-Multi-Audio-Split-Screen-Audio-Plugin-Beta
