How do you call/get audio files from the resource folder for IOS?

How do you call/get audio files from the resource folder for IOS? I tried to use Resource.load to get the audio files however it is not working for IOS/Xcode.. Now I am trying to use StreamingAssets to get the audio files. I can see that all my audio files goes to RAW folder however, I am not sure how do you properly call the audio file for IOS. Thanks in Advance..
