Sound cards enable the computer to output sound through speakers connected to the board , to record sound input from a microphone connected to the computer, and manipulate sound stored on a disk . Nearly all sound cards support MIDI , a standard for representing music electronically. In addition, most sound cards are Sound Blaster- compatible , which means that they can process commands written for a Sound Blaster card, the de facto standard for PC sound. FM Synthesis mimics different musical instruments according to built-in formulas. Wavetable Synthesis relies on recordings of actual instruments to produce sound.
Wavetable synthesis produces more accurate sound, but is also more expensive.
