How it's made
- Source
- an empty bottle rolling on concrete; continuous friction is pink noise at 65-1600 Hz. Aggregate contacts add 1-5 ms filtered noise excitations, not naked digital impulses.
- Body
- the enclosed air contributes a damped 185-320 Hz hollow mode; glass wall modes have inharmonic ratios 1, 1.47, 2.31, 3.68 and 5.13 above 650-1120 Hz, with 45-230 ms T60.
- Envelope
- eccentric rolling groups contacts at 1.2-3.5 turns/s; each turn has a weaker trailing contact. Smaller aggregate rattles occur between turns. Continuous motion sustains a 6 s loop.
- Modulation
- rotating contact pressure modulates rumble and grit together, with slow irregular spectral movement. Contact damping keeps the bottle ringing briefly rather than like a bell.
- Variation
- seeded timing, strength and excitation colour vary; glass tuning stays fixed per bottle. Presets distinguish heavy slow rolling, small bright glass, rough fast rolling and eccentric wobble.
- Space
- dry close perspective, centred object with no baked room or exaggerated stereo movement.
