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:
- https://nolanhergert.github.io/notes_old/programming/spirolab.html
- https://nolanhergert.github.io/notes_old/projects/spirolab.html
- 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!
- Sine waves are too loud when added together, cause lots of unnecessary clipping.
- Mouse position not accessible on Firefox?
- 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?
