An electronic oscillator is an electronic circuit that produces a repetitive electronic signal: sine wave, square wave and any other repetitive mathematical function.
So, why an Oscillator? Because, I'm currently looking at Audio, and Audio Effects (Distortion, Chorus, Delay, Flange, Reverb, ...) and the sound is basically a wave with a certain frequency.
How can you visualize your effect function? I've created this one above using Python and PyQt4. Less than 200 lines of code. Including the Oscillator class with 5 types of wave (ok, not so difficult).
You can find the source code here:
PyQt4 Electronic Oscillator Source Code.
Just downloaded. The code is extremely compact. Good job. :D
