A function simulator as a tool for educating digital sound basics
David Weenink · UvA-DARE (University of Amsterdam) · 2011
We describe a computer application that offers students and teachers, especially those with no real mathematical background, the possibility to learn the relation between, for example, elementary sounds and their mathematical formulation as sine functions with frequency, amplitude and phase parameters. The sampling of analog signals and the relation between the sampling frequency and a faithful representation of the sound can easily be demonstrated. Aliasing can be made audible and visible in several ways.
