analogue digital
  • Stored as sound waves
  • Loses quality each replication
  • Vulnerable to interference
  • better quality in original analogue file as sound is more accurate to original
  • Stored as binary values for waves with up and sown
  • Doesn't lose quality over time and stays same with each replication
  • Less vulnerable to interference due to simpler binary wave values
  • Uses samples to take reading from the original but not as good quality as the original analogue recording

In ADC (Analogue to Digital Conversion) the analogue signals are inputted to be stored and represented in a digital signal that can be understood by a computer and stored in the relevant storage. The ADC can also be used to convert Digital back to Analogue signal so that the user can hear the sound correctly.
