Ivory, a clean, marbly clack

Linear under thick caps: a clean, marbly clack.

What it imitates
Ivory models a linear switch under thick keycaps. Thick caps are what hobbyists credit for the hard, glassy note they call marbly. Ivory is brighter than Butter and dies away faster, so each key sounds more separate.
Teclo’s sounds are synthesized, not recorded. Its sound engine builds each pack from a model of the parts that make the sound, then plays the same files in the app that you hear on this page.
How it measures
Every pack is measured when it is rendered. The table puts Ivory next to Butter and Cricket, the packs closest to it in feel.
| Pack | Category | Brightness (Hz) | Press (ms) | 90% of energy in (ms) | Low/high (dB) | 1–3 kHz share |
|---|---|---|---|---|---|---|
| Ivory | Mechanical | 2,909 | 84 | 9.4 | -15.8 | 65% |
| Butter | Mechanical | 2,479 | 80 | 13.1 | -17.3 | 67% |
| Cricket | Mechanical | 3,148 | 70 | 7.1 | -12.8 | 46% |
Brightness is the energy-weighted mean frequency of a key press, so a higher number sounds brighter. Low/high is the energy below 1 kHz against the energy above it: the higher, the deeper. Nobody has tuned these packs by ear yet; the figures are what the files measure.
Who it suits
Fast typing where you want to hear every key as its own click without a ringing tail (a suggestion).
Use it in Teclo
- Click the keycap icon in the menu bar to open Teclo’s window.
- Pick Ivory in the list of packs, under Mechanical.
- Type anywhere. Teclo plays a different sound for a key going down and coming up, and separate sounds for Space, Return and Delete.
Every pack also has its own pair of mouse click sounds, made from the same model. Try the other packs on the sound packs page.
Questions
What is the difference between Ivory and Butter?
Both are linear switches. Ivory is brighter, with a centroid of 2,909 Hz against Butter's 2,479 Hz, and shorter, delivering 90% of its energy in 9.4 ms against 13.1 ms.
