How it's made
Source
a retro arcade sound chip playing two square-wave notes, a short pickup note and a longer reward note a fourth or fifth above it (classic B5 -> E6, 988 -> 1319 Hz). Duty cycle sets the hollow/nasal colour.
Body
the square is band-limited and low-passed at 3-11 kHz to tame fizz; a quiet octave-up square adds chip "ping", a soft sine an octave below adds weight, and a short high-passed noise tick marks the coin contact. A second-note shimmer partial (2.76x sine) gives a metallic coin ring.
Envelope
1.5 ms onset ramp (no click); the first note is cut after about 60 ms with a fast exponential fall, the second rings with a 0.1-0.35 s exponential decay; the whole sound is about 0.4 s.
Variation
`rng` detunes the second note by +-0.3 % and jitters the tick; presets change pitch, interval, gap, pulse width and decay (arcade, handheld, low dungeon, octave jingle).
