Using the 3D Surround Sound component adds amazing depth and body to your audio, compensating for monitoring limitations and sonic losses due to data compression. With 3D Surround processing the sounds will surround you, virtually putting you inside the music! 3D Surround enhances the sound played on conventional 2-speaker systems and makes even small PC speaker systems sound larger and richer. It is also fully compatible with Surround Sound playback systems.
