adding an audio clip as an event in the animation window

Hi, Bob Klassen,

You could check the video below about how to add an audio clip at specified time position in a clip,

You could also use this document as complementary material;

By the way, did you check the Unite2014 keynote? I think Unity might soon release a new director system for cutscene authoring.

Thanks, but I'm thinking of lip sync in a single animation clip, not in a cut scene.

Oh, I see,

Then, you could take the native animation event to implement it.

Just make a new MonoBehaviour and add a PlayAudio(string) method to it, attach the behaviour to the GameObject with Animation/Animator, then you could use animation event to call the PlayAudio(string) on your animation timeline.
