Sounds
------
No audio files are used. Every sound on this site (keyboard switches, bubble wrap, pop it,
pen and switch clicks, detent ticks, spinner whir, white/pink/brown noise) is synthesized in
the visitor's browser at the moment it plays, from original parameters written for this site.
No recordings, samples or sound packs of any origin are included.

Techniques (public, no code copied):
- Biquad filter coefficients: Robert Bristow-Johnson, "Cookbook formulae for audio EQ biquad
  filter coefficients" (published freely for anyone to use).
- Pink noise: Paul Kellet's "refined" pink-noise filter coefficients, posted publicly to the
  music-dsp mailing list archive.
