Detroit: Become Human Audio Extractor

Extract playable audio files from Detroit: Become Human!

A C# desktop app for browsing audio, listening to it and choosing what to export.

Requirements

1. Own Detroit: Become Human (Steam/Epic Games, or anywhere else)
2. Windows (64-bit)
3. Free space for your exports. A full export can get large, especially WAV.
4. Internet connection if dependencies are missing. The portable build includes the tools for offline use.

Features

1. Browse archives, banks, events and individual audio entries
2. Preview audio with pause, seeking and volume controls
3. Extract complete BNK banks and original WEM files
4. Convert audio to playable OGG and WAV, individually or in batches
5. Extract dialogue by language
6. Search by names, IDs, bank names and dialogue text
7. Read names from game files automatically
8. Export the whole library, track progress, cancel jobs and retry failed files
9. Group related audio and select several clips, banks or events
10. Browse MIDI sequences and export original .mid files, individually or in batches

How to use

1. Keep Detroit Audio Extractor.exe and the tools folder together, then run the EXE.
2. The startup menu checks your dependencies and downloads missing tools. Choose your game folder and click Open game.
3. Open All audio, or expand Banks and Archives to browse their events. Select a Type to narrow the current list.
4. Search for what you want. Search covers the whole library by default; choose Current view to search the selected bank or event. Clear search clears the text, and Reset filters resets language, type and codec.
5. Select an entry and click Play, or double-click it. Use Stop and the seek bar to control playback.
6. Use Ctrl and Shift to select several clips, banks or events, then use Export or Convert. Choose your format and output folder, check the file list, then start the export.

Group similar audio puts clips with related event/state names into expandable groups. Selecting a group exports its matching members. Bank exports BNK files; Event WAV/OGG renders each selected event separately.

Choose MIDI in the Type filter to browse sequences. Selected original, Filtered original, and Export All → Original preserve them as .mid files. MIDI entries show their stored track names and format details. MIDI playback and OGG/WAV rendering are unavailable.

Export All exports from the whole library, regardless of the current view or filters, and can take a long time. You can check the counts before starting. Existing files are skipped unless Replace existing files is selected.

Open file accepts .idx, .bnk, .wem, .dat and .dNN files. You can also drag files onto the window. Open the .idx to browse its archive set.

Keyboard shortcuts: Ctrl+O opens a file, Space controls playback, Escape stops playback, and Ctrl+A in the audio list selects all matching results.

Choose System, Light or Dark in Tools. System is the default and follows the Windows theme.

Notes

• Names are read automatically. Some music and sound effects still use IDs or labels from linked events. Details shows IDs and name sources.
• Some banks contain just the start of a streaming clip. Partial preview plays that part; OGG and WAV export require the full stream. Export fragment bytes saves the original fragment.
• Dialogue may contain long periods of silence.
• Some events depend on game logic or effects that the app cannot reproduce yet. Individual audio entries can still be previewed and exported where supported. Details and Jobs show errors.
• WAV defaults to PCM16. PCM24 and float32 are available in Tools. Each export includes a JSON report with filenames, results and audio metadata.

Build

Requires the .NET 10 SDK on Windows. Preparing the decoder from source also requires Visual Studio C++ build tools and CMake.

./scripts/Prepare-Tools.ps1
dotnet build DetroitAudio.slnx -c Release
dotnet test DetroitAudio.slnx -c Release --no-build -p:AutoPublish=false
./scripts/Package.ps1

The portable build goes in artifacts/DetroitAudio: one application EXE plus the offline tools folder. Source and Windows build ZIPs go in artifacts/packages.

The original console extractor is still included in Audio.sln. Its command line options include --logfile, --onlyextract, --delete-errors, --meltingpot and the dialogue language flags.
