Clacklab
Measure what your keyboard mod changed.
Clacklab turns your iPhone microphone into a focused acoustic analyzer for mechanical keyboards. Record a repeatable key sequence, inspect the sound profile, save the build, and compare before-and-after sessions.
Acoustic profile
Repeatable comparison, not a magic microphone score.
Clacklab measures frequency balance, decay, level, clarity, consistency, and keystroke character. Results are most useful when the room, phone position, keyboard position, surface, and key sequence stay identical.
Workflow
Built for before-and-after testing.
Check a foam, tape, switch, lubricant, keycap, or case change using the same capture protocol each time.
Analyze on-device
Capture deliberate keystrokes and inspect the waveform, frequency spectrum, decay, clarity, consistency, and experimental character score.
Save each build
Store keyboard and switch names, notes, metrics, and spectrum data locally on your iPhone.
Compare and export
Clacklab Pro compares two sessions side by side and exports a shareable result card or CSV file through the standard iOS share sheet.
Test protocol
Keep the setup identical.
- Use the same iPhone, room, desk surface, and keyboard position.
- Place the bottom microphone about 20 cm from the keyboard.
- Use the same deliberate key sequence and similar typing force.
- Compare sessions; do not treat an isolated score as a lab measurement.
Privacy
Audio stays on your iPhone.
Clacklab has no accounts, advertising, analytics, or tracking. Audio analysis happens in memory on-device. Saved results remain local unless you explicitly export them.
