What files does UNITY support?

I'm making a world for a project I'm working on, but I don't know what audio files unity supports, I tried .caf, and .ogg but it won't inport. can someone help me, by telling me what I might be doing wrong, or what files UNITY accepts, thanks in advance!

Hi Unity supports .aif, .ogg, .wav and .mp3 So you should be able to import your ogg file. What error do you get? You can see more information regarding importing audio here: http://unity3d.com/support/documentation/Manual/Audio%20Files.html
