Persona 5 Royal/ps4R.cpk/sound/bgm.awb

The bgm.awb is an AWB file found in Persona 5 Royal's ps4R.cpk. It contains all the main, non-DLC background music tracks in ADX format.

Encryption / Decryption
Keep in mind that tracks need to be encrypted/decrypted after you extract them, otherwise the modified audio would be corrupted in-game and most likely would give you hearing pains. You can use VGAudioCli to encrypt or decrypt the files with the same command.

Decryption
Follow this guide to decrypt the files, close the script by pressing Ctrl+C if it starts looping.

Encryption
You'll need the correct Keycode for your game's region, here's a list of keycodes:
 * JP: 10882899
 * CN: 29915170
 * EFIGS (US/EU): 22759300

Single file encryption
Move your file to the location of the executable VGAudio.exe and open a command window in the same location, then use the following command to encrypt or decrypt the adx file.

VGAudioCli.exe -c -i [input.adx] -o [output_enc.adx] --keycode [decryption key (Dec.)] You should change the output file name by including the _enc part to avoid confusion.

Multiple files encryption
You'll have to create 2 folders in the same location as the VGAudio.exe and put your files in the input folder. Then run the following command in a command windows: VGAudioCli.exe -b -i [input-folder] -o [output-folder] --out-format adx --keycode [decryption key (Dec.)]
