Unable to extract PS4 psarc file (Kamen Rider Climax Fighters)

[PlayaMoon]

Hello. I've been trying to rip the music used in this game. From what I know the game was made with Unity, so I used AssetStudio and figured the music assets are inside the media folder, but nope! Not a single trace of it (I did come across ingame models and sounds instead). After hours of figuring out what's missing I noticed a archive.psarc file in the root of the game directory. Does this contain the missing sound files I'm looking for? If so, how do I even open it? I tried multiple yet outdated tools but no success. Only one of the tools only managed to give one unity resources file of 130kb ._.

If anyone has experience with this do let me know, I'll even leave a link to the game's directory here.

The "archive.psarc" file would be in the root directory, but in case if i have overlooked I'm including the media folder as well.
