Glass Clink

How it's made

Source

two drinking-glass rims meet in a toast. A rounded 0.25 ms attack and 1.5–3 ms band-limited contact excite both shells simultaneously, without a low thump or brittle full-band digital click.

Body

each bowl has flexural modes near 1 : 2.66 : 4.9 : 7.3, not a harmonic musical series. The lowest mode dominates the high pure ring; progressively weaker upper modes lose energy faster (T60 0.09–0.30 s versus 0.45–0.92 s).

Interaction

the second glass is tuned a few Hz above the first and has a slightly different upper-mode pattern and damping. Their fundamentals beat gently, with modest stereo separation to preserve beating in mono. The tiny asymmetry of each rim also splits its lowest flexural mode by about 1 Hz.

Envelope

contact falls away immediately; upper modes disappear first, leaving the paired clear rings. A smooth final fade closes below the natural noise floor in about one second. No room reverb is baked into this dry foley.

Variation

seeded contact noise, shared pitch drift and independent upper mode mistuning change the strike subtly while preserving the beat spacing. Presets change glass size, wall damping, contact hardness and pair mismatch.
