A sound card (also known as an audio card) is an internal computer expansion card that facilitates the input and output of audio signals to and from a computer under control of computer programs. The term sound card is also applied to external audio interfaces that use software to generate sound, as opposed to using hardware inside the PC. Typical uses of sound cards include providing the audio component for multimedia applications such as music composition, editing video or audio, presentation, education and entertainment (games) and video projection.
Sound functionality can also be integrated onto the motherboard, using basically the same components as a plug-in card. The best plug-in cards, which use better and more expensive components, can achieve higher quality than integrated sound. The integrated sound system is often still referred to as a "sound card".

Famous quotes containing the words sound and/or card:
“You can’t, in sound morals, condemn a man for taking care of his own integrity. It is his clear duty. And least of all can you condemn an artist pursuing, however humbly and imperfectly, a creative aim. In that interior world where his thought and his emotions go seeking for the experience of imagined adventures, there are no policemen, no law, no pressure of circumstance or dread of opinion to keep him within bounds. Who then is going to say Nay to his temptations if not his conscience?”
—Joseph Conrad (1857–1924)
“I must save this government if possible. What I cannot do, of course I will not do; but it may as well be understood, once for all, that I shall not surrender this game leaving any available card unplayed.”
—Abraham Lincoln (1809–1865)
