game.sound

Lanternwake's score, ambience, sound-effect library and mix.

It listens on the shared bus and never calls another slice:

The fourteen library keys

ui_click · ui_back · lantern_open · lantern_hood · clue_read · sigil_claim · door_heavy · footstep_stone · footstep_mud · heartbeat · sting_spotted · sting_lost · crypt_open · caught

Anything may emit them: Core.emit("sfx", "door_heavy", { x, y, z }). A key that arrives twice inside its own hold window is played once, so a slice emitting lantern_hood on the same frame this module hears lanternToggled produces one sound rather than a flam.

The mix

Sound.master scales everything — the one knob a trailer is balanced on. Loud: the spotted sting, a spoken line, the catch. Under them: the score at 0.30 exploring and 0.54 hunted, the bed at 0.42, footsteps at 0.30. A line ducks the bed to 55% and the score to 34% for as long as it takes to say.

The heartbeat is a sustained loop whose level and pitch ride Core.state.fear and nothing else. Footsteps are metered by distance travelled — and shut off permanently the first time another slice emits a footstep of its own, so the two can never double up.

Two shapes of source, and they are not interchangeable

• Sustained — the bed, the two score decks, the heartbeat. Built with their clip and autoplay = true at creation, never started or stopped again; the mix moves them by volume alone. Each score deck owns one cue for the life of the session, so a cue change is two level ramps rather than a clip swap.
• One-shot — every library key and every spoken line, through playOneShot. The sfx, voice and spatial buses carry no clip of their own at all.

A multi-megabyte PCM clip takes several seconds from being referenced to being audible, which is why every sustained clip is bound in build().

The clips

Baked assets under /zero/source/audio/, made by audio.clipforge. The bed and the score are codec = "pcm" and seamless end to end — the bed's loop point is a smaller sample-to-sample step than the clip's own average, so it does not click. One-shots are Opus and stay small.

require("game.sound").debug() reports every level, which cue is up, and any library key whose clip is missing.
