how sound cards work
Digital sound is fundamentally different from computer data.
The sound is simulated.
They are made up of waves passing through matter.
When these waves vibrate their eardrum, people will hear the sound.
However, the computer uses pulses representing 0 and 1 for digital communication.
The sound card is like a video card, which is converted between the digital information of the computer and the simulated information of the outside world.
Sound is composed of waves passing through media such as air or water.
The most basic sound card is a printed circuit board that uses four components to translate analog and digital information: some sound cards use encoder/decoder chips instead of separate adc and dac, the codec that performs both functions at the same time.
