guys, there is no difference with the sound if it is compressed or not. When they master the sound in the studio, most of the time they cut off the highs and lows of a stream to make it fit into a certain amount of space in the file. On top of that, when they record music, you are only going to get as good of quality as the recording mics will permit. Uncompressed v compressed is only a delivery method. How they master that sound is key to having good sound while in game.
