spirolab

A fun visualization of the combination of interactive sine wave audio frequencies in the phase space. https://nolanhergert.github.io/spirolab/index.html

Also known as a spirograph or a lissajous figure, or a harmonograph. This is a lab for audio spirographs...spirolab :)

Old notes and ideas:

Features

Can adjust two frequencies at a time using the mouse. Explore your own chords, harmonics, and combination / tartini tones! (https://en.wikipedia.org/wiki/Combination_tone)
Visualization is fast and is full screen!
Keyboard shortcuts!

Bug fixes soon

Sine waves are too loud when added together, cause lots of unnecessary clipping.
Mouse position not accessible on Firefox?

Features soon

Touch support for phone.
Adjustable legends? Or just have map drop points and the legend is always frequency and amplitude?
Hint dots for good frequency combinations
Keyboard shortcuts
- Up/Down/Left/Right adjust in .1 hz increments? Can set probably
Enter amplitudes and frequencies manually. Amplitude can be negative...
Save links to fun ones and keep a running visualization of fun ones?
Look at old notes to see what other ideas I had
Have more frequencies be able to be added?
