But the problem with this code is that it lags a lot when it comes to "AudioClip someAudioClip = www.oggVorbis;" and it is not that big an ogg file that is being downloaded. I think it is because Unity
I have also tried to use WWW.audioClip which does not lag but as I have to download more than one sound in succession (to fill the atmosphereClips array) I don't think I can use that. I have not been able to detect when it was finished at least.
Hope someone has a better, more lag free way to do this.
