A sound card (also known as an audio card) is a computer expansion card that facilitates the input and output of audio signals to/from a computer under control of computer programs. 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). Many computers have sound capabilities built in, while others require additional expansion cards to provide for audio capability.
One of the first manufacturers of sound cards for the IBM PC was AdLib, who produced a card based on the Yamaha YM3812 sound chip, aka the OPL2. The AdLib had two modes: A 9-voice mode where each voice could be fully programmed and a less frequently used "percussion" mode with 3 regular voices producing 5 independent percussion-only voices for a total of 11. Creative Labs also marketed a sound card about the same time called the Creative Music System. A large change in the IBM PC compatible sound card market happened with Creative Labs' introduced the Sound Blaster card. The Sound Blaster cloned the AdLib, and added a sound coprocessor for recording and play back of digital audio (likely to have been an Intel microcontroller relabeled by Creative). The Sound Blaster line of cards, together with the first inexpensive CD-ROM drives and evolving video technology, ushered in a new era of multimedia computer applications that could play back CD audio, add recorded dialogue to computer games, or even reproduce motion video (albeit at much lower resolutions and quality in early days).

Some tips when you are planning to buy a sound card
- If you want to take advantage of the latest features in the new sound cards out there, you'll usually need to ensure you have a powerful CPU to go along with it. No point having the latest super-duper audio card if you're installing it into an old Pentium 3 computer.
- Do you have any special needs that you need to cater for? For example, if you're into professional, multi-track music recording, you'll want to get a proper multi-channel sound card. If you're into things like MIDI, you'll want a card that supports provides good MIDI support.
Sound cards are an essential component in computers today - they're your gateway to experiencing true multimedia. Make sure you consider your audio needs and do some homework before buying that sound card. If you don't need certain high-end features like multi-track recording support, or hard-disk recording, then go for a lower-end card.
