Sound Card: This Is How Computers Convert 1s And 0s To Sound

This is a well known fact that the entire functioning of computers revolves around 1s and 0s. Then, did you ever wonder how such a device is able to produce sound energy? How the music with different beats and levels is being obtained from the speakers? Well then, if that’s the question in your mind, then today you’ll find the answer right here i.e. about how your computers produce music.

Sound Card: This Is How Computers Convert 1s And 0s To Sound

Nature Of Sound Waves:

You must be familiar with the fact that sound waves are analog in nature. Usually sound travels from one place to another due to collision of energized particles with the others and so on. Due to these collisions, with distance the energy dies out. This is what you must have learnt long ago when you went to school.

But a computer is incapable of directly producing such vibrations from its digital data. So just like a processor, RAM and the other components have their fixed tasks, a sound card is the one which deals with such energy translations.


The Role Of Sound Card:

In a computer, each of the components communicates with each other digitally. Similar to a Graphic Card, a Sound Card converts the digital sound information into the human-perceivable sound waves (i.e. waves of frequencies 20-20000 Hertz).

The most important components in a Sound Card among the rest are:

  • A digital-to-analog converter (DAC), which helps convert the binary information into analog sound signal.
  • An analog-to-digital converter (ADC) to record the analog sound inputs and storing them as digital sound.
  • The connection interface which keeps the sound card attached to the motherboard, mostly a Peripheral Component Interface (PCI).
  • The various connectors to enable users to connect Mic or Headphones to the computer.
