# Arkham City Audio Toolkit
|
|
|
|
Replace any voice line, music track, ambience or sound effect in **Batman: Arkham City (PC, Steam)** with your own
|
|
audio (by name, from a file or a recording) and edit subtitles and menu text, with one-click revert. No Wwise, no
|
|
game patch, no external programs.
|
|
|
|
- **Unheard City** (`app/`, [user guide](docs/user-guide.md)): the desktop editor for Windows and Linux. Browse and
|
|
search all ~26,900 sounds of the game (the voice lines of one language, music, ambience, and ~15,400 effects
|
|
stored inside soundbanks: footsteps, foley, combat, weapons, UI), filter by category and character, listen,
|
|
replace or record, apply and revert. Edit subtitles (11 languages, linked to their speech lines) and the menu
|
|
text in their own sections.
|
|
- **`ackit`** (`ackit/`): the Python library and command-line tool behind it.
|
|
|
|
How it works in one paragraph: the game's Wwise 2011.1 decoder only knows the standard Vorbis codebooks, so ackit
|
|
encodes with libvorbis and rewrites the stream into exactly the layout the game expects (codebook IDs, packet
|
|
format, seek table, header hash and memory size reversed from the game), then writes it into the `.wad`
|
|
archives atomically, keeping the original bytes in a store for exact reverts. Details in `docs/`.
|
|
|
|
## Install
|
|
- **Editor (users), Windows:** unzip `UnheardCity-<version>-windows-amd64.zip` and double-click **Install.cmd**.
|
|
It installs for your user (no admin rights), adds a Start menu shortcut and an entry in Settings > Apps for
|
|
uninstalling. Or skip installing and run `UnheardCity.exe` straight from the unzipped folder.
|
|
- **Editor (users), Linux:** unpack the `.tar.gz` and run `UnheardCity`.
|
|
- Nothing else is needed (no Python, no Wwise, no ffmpeg). To build it yourself: [docs/building.md](docs/building.md).
|
|
- **Toolkit (developers):** Python 3.10+:
|
|
```
|
|
python -m venv .venv && .venv/Scripts/activate # Linux: source .venv/bin/activate
|
|
pip install -e .[app,dev,verify] # app = editor, dev = tests/packaging, verify = in-game test
|
|
python -m app.main # run the editor from source
|
|
```
|
|
|
|
## Quick start (command line)
|
|
```
|
|
ackit find joker tape # search by name, category or character
|
|
ackit extract Speech_TAPE_JOKER_1_4 orig.wav # listen to the original
|
|
ackit replace Speech_TAPE_JOKER_1_4 my_line.wav --match-loudness
|
|
ackit revert Speech_TAPE_JOKER_1_4 # or: ackit revert --all
|
|
ackit text find --lang ITA protocollo # subtitles and menu texts (keys SUB:... / MENU:...)
|
|
ackit text set "MENU:ITA:FRONTEND.ITA:Menu:Start" "Premi Invio"
|
|
```
|
|
More: `ackit status`, `ackit list --character Joker`, `ackit export-mod my.acmod` / `ackit import-mod`,
|
|
`ackit verify` (offline self-check), `ackit game` (detected install, language, store). `ackit -h` lists all
|
|
commands. The game folder is found through Steam (Windows, Linux, Flatpak, Proton); otherwise pass `--game DIR`.
|
|
|
|
Rules worth knowing: speech/effects replacements must fit in the original's size (the tool squeezes or refuses
|
|
with the maximum length); music can be any length. Subtitles must fit the original text's length (menu text:
|
|
any length). Close the game before writing.
|
|
|
|
## Where things are
|
|
```
|
|
ackit/ library + CLI (formats, encoder, injector, catalog, originals store, workspace)
|
|
ackit/verify/ offline self-check, in-game test harness (Windows, WinDbg)
|
|
app/ Unheard City (PySide6)
|
|
tests/ pytest suite (synthetic game data; real-game tests run when the game is installed)
|
|
data/catalog/ sound catalogs (CSV), character lists (source/), schema in data/catalog/README.md
|
|
docs/ formats, reverse engineering, decisions, categories, user guide, building
|
|
tools/ catalog builder, packaging (build_app.py, installer/), artwork and license scripts
|
|
NOTES.md project status and working notes; CLAUDE.md: guidance for AI sessions
|
|
```
|
|
|
|
Tests: `pytest` (the real-game tests are skipped when the game is not installed).
|
|
In-game test (Windows, Steam running, WinDbg installed): `ackit verify --ingame`.
