bangu, cymbal and tom have no recording yet; the game synthesises them.

## Local processing

`tools/audio_prep.py` builds everything in this folder from the downloads.
The fight loop is stored as FLAC so its beat grid stays sample-exact, since MP3 adds encoder padding.
Each loop ends with an equal-power crossfade into the audio just before loopStart, so the wrap is sample-continuous.
Music is normalised to −19 dBFS RMS. Effects are trimmed, faded, peak-normalised and stored as mono FLAC.
Mix gains in manifest.json were set by offline-rendering the synth and the recorded versions through the game's own mixer and comparing them.

## English narration (ElevenLabs, 2026-09-26)

49 English lines generated in the owner's ElevenLabs workspace with **James – Husky, Engaging and Bold**, **Eleven Multilingual v2**. Speed 1.0, stability 0.5, similarity 0.5, style 0.1, speaker boost enabled. https://elevenlabs.io/

The three downloaded originals and sentence boundaries are preserved in `art/audio-src/narration/`. Two-second SSML breaks were removed during sentence splitting. Files are mono 44.1 kHz MP3 at 96 kbps, normalized to -18 LUFS / -2 dBTP. They play through the speech bus, with music ducking; subtitles remain available when speech is switched off or unavailable.

`tools/narration_prep.py` reproduces the cuts from the saved originals. The spoken line about disregarding the innkeeper is retained as an unused alternate. New inspection and bracing actions are adaptations for this game.


## Theatre films (Hyper3D, 2026-09-26)

Opening and closing films generated in the owner's Hyper3D Video workspace, Text to Video, Default Creator Limited Free, 16:9, 720p, 5 seconds, sound effect disabled. https://hyper3d.ai/workspace/video

Original downloads are preserved in `art/video-src/`; web copies are H.264 MP4 with fast-start playback. The opening still supplies the title-screen artwork. Films are skippable and do not replace gameplay. The mountain passage and return vignettes are dramatic adaptations inspired by the Wu Song story.

## Journey leather artwork (2026-09-26)

Two hunters, lantern, staff, fallen branch, stones, signpost, bird and stream were generated with OpenAI image generation using the existing game artwork as a style reference. Transparent atlas originals are bundled under `assets/scenery/journey-*-atlas.png`; individual sprites are selected with texture coordinates without altering the originals.

## Film music (2026-09-27)

Opening and closing web films now contain AAC music tracks cut from the first 5.041667 seconds of the existing Suno `lamp.mp3` and `epilogue.mp3`, respectively. Each cue has a 0.18-second fade-in and a fade-out from 4.2 seconds to the end. Video is copied without re-encoding; silent originals remain in `art/video-src/`. Embedded music follows video playback and stops on skip.
