env(i: number, n: number, attack: number, release: number) → number

square(phase: number) → number

tri(phase: number) → number

blip(dur: number, f0: number, f1: number, wave: string, gain: number) → void

A blip: one pitch sweep under a hard attack and an exponential tail.

mix(a: { number }, b: { number }) → void

concatPcm(parts: { { number } }) → void

move( ) → void

confirm( ) → void

back( ) → void

start( ) → void

pause( ) → void

deny( ) → void

ensureClips( ) → void

emitter(id: string) → any

One emitter entity per sound, so playing two in the same frame does not cut the first one off. Re-created on demand: a mode flip reloads the scene and takes runtime entities with it.

play(id: string) → void

Play a cabinet sound. Routed through the sound slice when it has landed — it owns the mix — and synthesised locally when it has not.

prewarm( ) → void

Build every clip now, so the first menu move is not the call that pays for the synthesis.

report( ) → void

Report what the local fallback actually built — a clip that decodes to zero frames is the failure that otherwise ships silently.

teardown( ) → void

Drop the emitter entities this module spawned. Only entities it created.
