Fast Fourier Analysis in action.
Any complex waveform, sound, or shape can be perfectly reconstructed as the sum of simple rotating circles (epicycles).
For those who are interested, these are my last meter patches. Some implementations may not be the best, Stereoscope is a data structure example in vanilla document, I have made some slight modifications
@Naskomusic Not entirely; some use data structures and canvas. I would also like to use pdlua, but unfortunately, pdlua doesn’t seem to be well optimized for graphics
