This is a sound effects pack from the Playstation 5's menu. These are really nice, high quality sounds and they were recorded with background music off. I ripped them from this source: "https://www.youtube.com/watch?v=Mdh1G7TQhVM&t=0s". I made sure there was zero popping in the audio. There's two sets here with the startup sound too. It's good to go! Enjoy!
To use these, simply download and unzip the file. Place the folder into your "LaunchBox/Sounds" folder. Then launch BigBox and go into the "Options" select "Sound" and change the "Sound Pack" to "PS5".
