Year 9 – Lesson 5 – Sonic playground

Curriculum KS3 Unit Lesson

First, learners will revisit the digitisation process, in order to understand how the sampling rate and the sample size affect the size and quality of the representation. Next, they will use a sound editing program that will allow them to experiment with sound to complete specific tasks and challenges.

Learning objectives

  • Calculate representation size for a given digital sound, given its attributes
  • Explain how attributes such as sampling frequency and sample size affect characteristics such as representation size and perceived quality, and the trade-offs involved
  • Perform basic sound editing tasks using appropriate software and combine them in order to solve more complex problems requiring sound manipulation
