Bottle Glug

How it's made

Source

alternating liquid slugs and incoming air pockets at an inverted bottle neck, 5-10 gulps in 1.7 s. Large 6-17 mm effective bubbles ring near 190-540 Hz; shrinking pockets produce upward pitch sweeps.

Body

air gulp noise excites a broad 260-530 Hz neck cavity and a weaker upper neck band at 2.7 times that frequency. As air volume grows, the cavity falls slightly while the bubble pitch rises.

Envelope

each gulp has a rounded 9-18 ms opening, a 70-140 ms liquid surge and a damped bubble tail; a smaller bubble follows 32-60 ms later. The final gulp weakens and all energy fades by 2.05 s.

Layers

band-limited turbulent water links the pulses; short airy suction precedes each main bubble. No room reverb or glass impact is added: this is a close, dry pouring action.

Variation

seeded timing jitter, bubble size, suction colour and strength prevent mechanical repetition. Size controls pocket and cavity scale; gulps sets cadence, air sets suction, rise sets pocket contraction.

Presets

small bottle is quick and bright; jug is slow and deep; narrow neck separates hollow gulps; last dregs has irregular, airy pulses and sparse residual bubbles.
