• Sound is stored digitally on computers
  • However, humans hear and speak in analogue sound waves
  • An ADC (analogue to digital converter) is used to record
  • A DAC (digital to analogue converter) is used to play audio

  • They also a higher sample size, which is the number of bits used to store a sample
    • The sample size determines the values that can be used to represent the amplitude
