Document Summary

The audio subsystem consists of speakers and a sound card. Two types: amplified speakers (which use external power) or unamplified speakers (which use internal power) Amplified speakers generally produce better quality sound, but they do not adequately reproduce the bass sounds that t make gaming and musical scores sound richer and fuller. For better bass sounds, a speaker system that includes a subwoofer would be good. Sound cards attach to the r motherboard and enable your computer to produce sounds. 3d sound is better at convincing human eats that sound is omni-directional, meaning you can not tell from which direction it is coming. To set up surround sound you need two things: a set of surround-sound speakers and a sound card that is dolby 7. 1 compatible. Modern computers only understand two sates of existence: on and off. Electronic switches are devices inside the computer that can be flipped between these two states: 1 meaning on and 0 meaning off.
