Derived from the source's HQ preview; trimmed 0.26–1.46 seconds, amplified 6 dB,
short endpoint fades, encoded as AAC. Downloaded 2026-10-31.

Yarmeong voice recordings were supplied by the project owner. Copies are AAC
encoded with short endpoint fades; the first three recordings have leading
silence trimmed. The latest five clips (kingbad, 123 autotune, 123 clean, 133, 126) form the
random pool for both direct petting and the Yarmeong button.

Remaining synthetic effects and the snack-bar and rest-room scores are procedural Web Audio compositions in this repository. The lobby now uses the six owner-supplied tracks listed below.

## Owner-supplied recordings · 2026-11-01

These 24 recordings were supplied by the project owner for this Site. No public-domain or redistribution license is asserted. MP3 and WAV inputs are AAC-encoded; AAC inputs are remuxed to seekable M4A, preserving their audio. Original uploads are unchanged. Full file mapping and duration are in `uploaded-audio-manifest.js`. Long ambience and music stream; action cues use a bounded decoded cache.

## V26 loudness balance and owner replacements · 2026-11-02

Versioned derivatives in `normalized-v26/` preserve all earlier files. The six
new ambience sources and walking source below were supplied by the owner in
this request; no public-domain license is asserted for these recordings.
All manifest music and ambience use EBU R128 loudness normalization toward
−20 LUFS and a −2 dBTP ceiling. Recorded foreground action cues target −18 LUFS; short walking hits target
−20 LUFS so repeated steps stay below foreground effects. The
242 ms cupboard-close recording is too short for integrated EBU measurement
and instead uses peak normalization. AAC outputs are decoded and measured
after encoding. Clips with isolated peaks receive transient compression before
normalization so the quieter recording body is audible within the peak limit.
Endpoint fades are 25 ms or shorter. Complete source hashes,
output hashes, durations, filters and measured results are in
`docs/qa/audio-normalization26.json`.

| Game ID | Owner upload | New file |
| --- | --- | --- |
| sauna_ambient | 사우나 배경음.aac | normalized-v26/sauna-ambient.m4a |
| bath_ambient | 목욕탕 소리(1).aac | normalized-v26/bath-ambient.m4a |
| snack_ambient | 매점소리(1).aac | normalized-v26/snack-ambient.m4a |
| clay_ambient | 황토방 소리(2).aac | normalized-v26/clay-ambient.m4a |
| private_ambient | 우리끼리방 배경음(2).aac | normalized-v26/private-ambient.m4a |
| restroom_ambient | 화장실소리(배경음)(1).aac | normalized-v26/restroom-ambient.m4a |
| footstep_1 | 걷는소리(1).aac; 0.06–0.49 s excerpt | normalized-v26/footstep-1.m4a |
| footstep_2 | 걷는소리(1).aac; 0.55–0.98 s excerpt | normalized-v26/footstep-2.m4a |

Other `normalized-v26` files derive from the already credited earlier game
assets, retain their respective licenses, and use IDs with underscores
replaced by hyphens. In particular `locker-close.m4a` remains CC BY-SA 3.0,
`dryer.m4a` remains CC BY 3.0, and `flush.m4a` and `locker-open.m4a` remain
public-domain derivatives. No separate salt-room or stretch/yawn recording
was supplied. Salt can share the owner's clay-room ambience; a synthetic
stretch sound must not be described as a recorded human vocalization.

### V26 rooftop rain replacements · 2026-11-02

The owner supplied two additional rain recordings for the covered rooftop
shelter. These replace the V26 rain derivatives while preserving the earlier
source assets and original uploads. Both target −20 LUFS with decoded AAC
true peaks at or below −2 dBTP and 40 ms endpoint fades.

| Playback ID | New owner-supplied recording | Derivative |
| --- | --- | --- |
| soft_rain | Epic Stock Media - Ambient Nature - Soft Rain Dropping on Leaves .aac | normalized-v26/soft-rain.m4a |
| hard_rain | Soundholder - ambient rain under a plastic roof with medium intensity.aac | normalized-v26/hard-rain.m4a |

The second recording is medium rain heard beneath a plastic roof; the
internal `hard_rain` ID is retained for compatibility and is not a claim that
the supplied recording depicts extreme rainfall. No redistribution license
is asserted for the owner's uploads. The final measurement report records
these new sources, hashes, actual decoded durations and processing.

## Revision 27 · stretch recordings and food Foley

Two owner-provided Artlist vocal recordings, normalized to -18 LUFS with -2.2 dBTP target and short fades; no pitch or speed change.

- ./assets/audio/actions-v27/stretch-1.m4a: Artlist Original - The Lights - Vocal Ohhh F Sharp 162 bpm.aac

- ./assets/audio/actions-v27/stretch-2.m4a: Artlist Original - Hablando vocal male ohh 100 bpm Bb echo.aac

`food-foley.js` creates original procedural ramen suction/lip/gulp sounds and hotbar bite/chew sounds. These are synthesized, not recordings from the provided Artlist files.
