The poster must explain the following keywords:
  • bit depth
  • sample
  • sample rate
  • Hertz
But see if you can include some more advanced keywords.

Your revision poster should be able to help you answer:
  • How does bit depth affect the size of the file?
  • What effects the quality of a sound file?
  • How do you calculate file size of a sound file?
  • What does a sound waveform look like? And where would you find the samples?

You can use the worksheet from today as well as BBC bitesize, and a PDF of the slides. Remember this is about advancing your understanding - not about copying and pasting!
