Sounds

Sound is another form of data that is stored on a computer. Similar to other types of information such as numbers, text, and images, the sound is also stored in digital form. But, sound, when produced, is in analogue form, that is, continuous varying data. To store sound in the computer, it is sampled to obtain thousands of samples per second where each sample corresponds to a binary value.

This A Level Computer Science module introduces sounds to your students, explaining:

  • Storing sound on a computer
  • Sampling and Nyquist’s theorem
  • Factors that affect the audio quality of audio files in detail
  • Musical instrument digital interface (MIDI) files
  • How to calculate the size of an audio file
