Non-audio software that’s useful in teaching audio

        Thinking back to software that’s not designed for audio education per se, but is still useful in teaching audio, Grapher is the first that comes to mind. It’s part of the macOS by default, but I’m sure there’s a PC alternative available also. It’s useful for demonstrating concepts like the addition of odd harmonics at inverse amplitudes to form a square wave as shown below.

          Falstad’s browser-based simulations have been a staple for me in the classroom for well over a decade, although one could easily argue that they are specifically designed for education.

          The Circuit Simulator is particularly impressive. It’s an interactive, modifiable, animated circuit simulator app that runs in real-time (and is modifiable in real-time). The example below shows a High Pass Filter (RC), where the frequency is varied over time to show the impact on the output voltage.

              Thanks for reminding us about grapher!
