Time Freeze

How it's made

Source

a spinning mechanism winding down, like a tape or turntable losing power. Two detuned saws plus a sine an octave below carry the pitch; a pink-noise breath rides on top as the air of the moving machine.

Body

pitch falls along a decelerating exponential (about 3 octaves at default depth) and a low-pass closes with it (5 kHz down to 250 Hz, Q ≈ 1.2), so the sound thickens and darkens as the harmonics are swallowed. A low shelf (+5 dB at 160 Hz) adds weight while the top disappears.

Envelope

a soft 40 ms swell, a level that holds for about 45 % of the length and then fades; the pitch keeps sinking until nothing is left. A soft sub thud (110 → 45 Hz) marks the moment the world stops.

Space

the suspension is the sound, so a hall reverb is baked in. The dry part fades first and the reverb tail rings on into silence, which is what makes time feel held rather than cut.

Variation

`rng` detunes the saws by ±1.5 % and varies the noise stream; parameters set length, depth of the pitch drop, darkness of the filter, reverb amount and breath. Presets differ in all of these.
