Modems unplugged - sound representation

All data on computers is stored and transmitted using the binary number system. When the binary digits need to be sent over the phone lines (which often happens in home internet connections), the digits are converted to sound and decoded at the other end using a modem. This activity uses audio coding similar...

Crazy Character Algorithms Activity: an Introduction to Sequences of Instructions

Children in lower primary settings can create their first algorithm using this Barefoot Computing unplugged computing activity. A picture of a 'crazy character' is decomposed into simple shapes. The instructions for drawing it are shared with the class who follow and attempt to reconstruct the picture. This...

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...
