  1. Many sound cards are able to produce advanced sound broadcasts beyond simple stereo. 3-D sound is typically used in games to enhance a user's experience. Based on a player's place in a game, 3-D sound can be realistically produced from different directions and can reproduce the effects of sound traveling around obstacles. Surround sound also produces sound from many directions, but it doesn't change according to what the listener is doing. Surround sound is common in home theater systems.
