Arcade Hall Texture

How it's made

Source

a room of arcade cabinets heard as a whole. Each cabinet plays an attract-mode melody fragment on a pulse-wave sound chip (2–6 notes of 70–140 ms, pulse width 12.5–50 %), scattered at random in time.

Body

the cabinets sit at different distances; air and the room absorb highs, so every blip is low-passed (1.8–6 kHz) and thickened by a short room reverb. Cabinets use different registers (≈ 330–1400 Hz) and share one pentatonic scale, so overlapping fragments stay consonant.

Hum

mains-driven transformers and fluorescent ballasts hum at 50/60 Hz with strong 2nd and 3rd harmonics (≈ 1 : 0.6 : 0.35 : 0.15) and slow wander, over a quiet low-passed pink room tone.

Effects

now and then a coin or laser sweep (rising or falling 0.15–0.3 s square chirp) and a soft noise thump from a button or a crashed ship, kept low in level.

Variation

`rng` picks each fragment's scale degrees, rhythm, pulse width and detune; `density` sets how often fragments start, `distance` how muffled the hall sounds.
