Sound drivers enable the output of sound from speakers and also to record sound from an input device like microphone which is connected to the computer. It also enables to manipulate sound that is stored on the disk. It has chips and other circuitry required for Digital to Analog conversion and vice-versa.What we hear is Analog data and what is processed by the computer is Digital data. Computer sound card drivers are used to strengthen, hear and record sound. It is because of these, that we can use our computer to deal with audio like listening to music.
Sound cards are basically divided into three parts or categories in terms of the installation. The first one is the card itself. It is directly installed on the motherboard of the computer. The second category is the sound card board. You need to install this card in the ISA/PCI slot in the motherboard. And the third category is an external sound card. In order to use this, you should connect to another computer via external interfaces like USB. When you listen to any voice, digital data waves like MP3 transfer to the sound card, the digital signals are converted into analog signals through DAC or digital to analog converter and come out of the speakers amplified. Similarly, when you record some sound through microphone, analog signals get converted to digital signals through ADC or analog to digital converter and is stored on disk in the form of MP3 or similar format.
