Usage

1. Find your audio files, For example for Genshin Impact

GenshinImpact_Data/StreamingAssets/Audio/GeneratedSoundBanks/Windows

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

2. Install dependencies

• Windows run the setup.cmd (you can double click it or run though command line similar to MacOSX and Linux)
• MacOSX or Linux run the script

./setup

3. Run the program

• Windows run the decode.cmd (you can double click it or run though command line similar to MacOSX and Linux)
• Any platform run with node from terminal

node decode.js

The files in ./input will be converted to .wav files by default inside ./output.

Options

Extra encoding

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

Valid arguments are flac, mp3

Can be entered multiple times for multiple export

Example

node decode.js --extraEncode flac
node decode.js -e flac -e mp3

Encoding details

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

Customs bms script

The deps installer installs the latest collection of bms scripts to ultilize, you can pass an argument to set this.

default: wavescan.bms

node decode.js --bmsScript custom.bms
