# Chest sound sources

Catches and lids of the sealed containers left around the valley. Their
electronic layers (keypad blips, unlock chirps, maglock bolts, the seal's
hiss, the lid servo, the vault chime and the lights powering down) are not
files: [`src/chest-audio.ts`](../../../src/chest-audio.ts) synthesises them
into the sound mixer when the world is built. Every recording here is
trimmed from a Freesound upload released under
[CC0 1.0](https://creativecommons.org/publicdomain/zero/1.0/) (public domain).
[`scripts/build-chest-audio.py`](../../../scripts/build-chest-audio.py) holds
the exact cuts: it trims each segment, mixes it to mono at 48 kHz or less,
normalises its peak to -1 dBFS, fades its ends and encodes Ogg Vorbis.
