Mechanical Transformation

How it's made

Source

a machine folding into a new shape. Small electric servos run in quick, irregular moves: each is a pulse/saw tone whose pitch glides 70–350 Hz between positions, with a thin gear-mesh noise band at 2–5 kHz.

Locks

steel latches snapping home are 1–3 ms noise bursts exciting inharmonic metal-bar modes (0.07–0.15 s decay scale), plus a short low hollow knock (190–290 Hz) from the housing; two heavy locks, one at the end, are larger and lower than the light latches.

Whir

a drive motor spools up under everything, three detuned saws rising 90 → 700 Hz through an opening low-pass (300 → 5000 Hz), with pink-noise hydraulic air hiss and a brown-noise sub swelling the same way.

Envelope

servo moves are packed densely early and thin out as the form settles; the whir crescendos to about 85 % of the length, then spins down quickly; the final lock rings out over the last 0.5 s.

Variation

`rng` picks move times, durations, pitches, lock tuning and pan; macros set the amount of servo activity, lock weight, whir level and the brightness of the whole machine.
