At first, beep / beep was acting primarily as a signal or warning. Later, developers created music for games that can be played on a PC using a long beep sounds and the pitches are different. Unfortunately, this music sounds not very realistic
Fortunately, computer sound capabilities increased rapidly in the 1980s, when several manufacturers introduced add-on card that is destined to control the sound. Now, a computer with a sound card can do far more than just beep. Soundcard today than can generate 3-D sound for games or featured surround sound for DVD, can also capture and record sound from external sources.
Analogue vs Digital
Voice and computer data are essentially different. Shaped analogue sound wave made from traveling through the material. People hear voices when the physical wave vibrating in their ear drum. Computers, however, communicate with us digitally, using electrical impulses representing 0s and 1s. As the graphics card, sound card translates between the digital information from computer and information from the outside world that shaped the analog. Made of sound waves that travel through the media, such as air, or water.
Materials soundcard maker of the most fundamental is a printed circuit board (PCB) that uses four components to translate analog and digital information:
Converters analogue * A-to-digital (ADC)
* A converter digital-to-analog (DAC)
* An ISA or PCI interface for connecting the card to the motherboard
* Input and output connections for a microphone and speakers
If it is usually a separate ADC and DAC, there are some sound cards that use the chip coder / decoder, called the CODEC, which performs two functions above. A sound card must translate between sound waves and bits and bytes.
