Sound

Sound is another form of data that is stored on a computer.  Similar to other types of information such as numbers, text and image, sound is also stored in digital form. But when sound is produced, it is in analogue form, that is, continuous varying data.

This KS3 Computer Science module introduces sound to your students, explaining:

  • Storing sound on a computer
  • Factors that affect audio quality of audio files in detail
  • How to calculate the size of an audio file
  • Estimating download time
