There are two variables that determine the accuracy of a digital representation of an analog sound wave.. Bit Depth and Sample rate. In this video I explain how analog to digital conversion works.
   • Bit Depth and Sample Rate  
Sound is naturally continuous analog information, so in order to store this wave of continuous information on a computer, it needs to be converted to numbers that represent this information. Each number represents a discrete point in the analog wave as it goes up and down for amplitude information, and left to right for timing information. Your computer has to play a game of connect the dots with these numbers to reconstruct the sound wave in a language it can understand. The extent to which digitized sound matches the original sound depends on the accuracy at which the computer, or interface, samples this analog information.
It helps to have a basic understanding of how sound waves work in the physical world before you get into how the digital world represents them. So here’s a link to my video on phase and the physics of sound if you haven’t already seen it.
