What is the best way to use a music background, and
not consume to much resources.

how make a loop background sound ( on all level game ) , using few unity resources,
to not affect performance and fluidity of the game.

The fasted method would be an uncompressed audio file, but regarding music that's not really an alternative because memory usage is way too high. I would not even load a compressed audio into memory, but stream it from disc. Depends on length and target platform.

You should be able to use a single, compressed audio stream (mp3 on iOS/android/osx, ogg on pc) without a noticeable performance loss. On iOS you can use hardware decoding for one audio stream.

What is your target platform? On PC everything should usually be using OGG compression without noticing a real performance drop.

If you want the music to play continuously without restarting on level load, you should have a look at http://unity3d.com/support/documenta...royOnLoad.html. AudioListener and AudioSource should be flagged this way.
