Convert Genshin Impact audio files into a playable format

Genshin Audio Extractor

Usage

1. Extract your audio files from the Genshin Impact datafiles.

GenshinImpact_Data/StreamingAssets/Audio/GeneratedSoundBanks/Windows

Move the .pck files you want to extract into a folder. The files must be directly inside the folder - no subdirectories.

2. install dependencies

npm install

3. Run the program

node decode.js --input <your specified input>

The files in <your specified input> will be converted to .wav files inside ./output.

Options

You can pass an optional argument to export the audio in different formats.

Valid arguments are flac, mp3 and flacandmp3

node decode.js --input flac --audio flac

Encoding details

flac: lossless, 16bit, 44100 sample rate
mp3: 320kbit/s, 44100 sample rate

Todo:

• Clean up dependencies

• Cross-Platform (Win, Linux, OSX)

• Multi-export support (FLAC, MP3, etc)

• Automatically remove processed files once complete

• Multithreading

• More?

genshin-audio-extractor's Issues

--audio flag detected as boolean instead of string

Using --audio for me isn't working.

node decode.js --verbose --input input --audio mp3
node decode.js --verbose --input input --audio flac
node decode.js --verbose --input input --audio flacandmp3

With every command above, args['--audio'] is null.

Adding a breakpoint in the "filter" function at decode.js:26, --audio is passed as boolean, ignoring the real value.

When enforcing the --audio flag as mp3, everything is working as intended.

Music Titles!

I manually mapped most of the music tracks to the Official Soundtrack. This order seems likely to change with their next update because I can't see any real order here.

There are a few interesting songs that I can't figure out where they are from, namely Music12_1 and Music 28_7. Both introduce new instruments that aren't used anywhere else in the soundtrack like Rock Guitar and Electric Synths.

Add support for OGG file format

hello~ just a feature request I think OGG files should be supported as well

Output folder name cuts off if there is a "." in the pck file name

The pck files with names starting with "Music_1" have all been merged into a single folder.

Missing some samples at the end of file

Hello. Thank you so much for your script. It works wonders on extracting the audio.

The only issue I've found is some files end up cut at the end, almost always a few milliseconds. I don't know if this problem is caused by one of the used tools, my guess is that the frames are either 2048 or 4096 samples and they are cut on the last frame that is >= 2048 or >= 4096. So the last few milliseconds (a thousand samples or so) are left out from the output file.

Some files are not affected as they may have had silence at the end so it's not noticeable. Some examples are: /English/ External0_1, External0_10, External0_30.

Any ideas on what could be causing the issue?
