Introduction to sound and music computing

A highly technical overview of how sound is represented in a computer, how digitising sound changes the quality of it and how reducing the sample rates can effect the resulting audio. The resource also comes with a number of sound samples to illustrate these concepts, along with both Python and Scratch programs to...

Computational thinking and algorithms

An unplugged activity to convert binary numbers into coordinates that enable students to recreate an image using values given in binary. The resource also includes a spreadsheet which can be used to make more complex images for use with students at a more advanced level. The presentation is more of a discussion of...

Making data digital

This resource looks at various ways at how digital images and sounds are quantified in such a way that the computer can store and interpret them. This looks at the effects of digitising different types of data, and the effect that this has on both the size and the quality of the resulting files. It may be necessary...
