Is it possible to add some events to a sound

I’d like to add some events to sounds (like for animations)
example : I have a wave with 2 or more voices, I’d like to detect which character is talking to use my lipsynch with the correct character.

Yeah, the Audio Listener has some functions that might be helpful…sort of…if you really know what you’re doing. Maybe “GetOutputData” or “GetSpectrumData”? But it seems like you have to be pretty familiar with audio programming to get it working.

I found this forum thread discussing lip synching solutions: http://forum.unity3d.com/threads/89196-Lip-Syncing-in-Unity

FaceFX for Unity seems like the “best” solution - but it also seems very expensive. Still, you can see their web demo, and it looks pretty spectacular: Unity Demo | OC3 Entertainment
