ClatterDrive Audio Demo

Mechanical HDD behavior, rendered as sound.

These are browser-playable renders from the current ClatterDrive engine. They are not recordings of a real disk and they are not bundled sound effects. Each clip comes from a different simulated workload and mounting condition so the low end, tick texture, and enclosure bloom actually change.

Spin-up, idle, park

Cold power-on through spindle run-up, early servo activity, a short idle period, then a final park. This one uses the desk-coupled mounting profile.

Why it sounds this way: the desk/table structure path adds more low body during run-up, while the late sharp transient is modeled park/contact behavior.

Idle to standby to wake

Active drive, park into a quieter standby-like state, then wake back into seek and transfer activity. This is also rendered with the desk-coupled profile.

Why it sounds this way: the low-frequency mounting path stays present through the wake cycle, so the main contrast is the park/wake transition rather than a simple change in seek rate.

Metadata storm

Dense bursts of metadata and journal-style seeks with occasional recalibration-like interruptions and heavier flush-like jumps, rendered with the bright bare-drive lab profile.

Why it sounds this way: this one strips away most desk/enclosure bloom so the servo-wedge tick texture and brighter exposed seek structure are easier to hear.

How these were made

The same repo that serves the fake drive also renders these clips. Regenerate them with uv run python -m tools.generate_readme_demo_samples.

The current README and this page intentionally use three different situations rather than three almost-identical steady-state loops, so the differences in structure coupling, power-state behavior, and seek texture are actually audible.

These public demo clips are peak-normalized for browser playback. The normalization is only for the checked-in sample artifacts; it does not change the live engine model.
