What is a NUS3AUDIO file?

A NUS3AUDIO file is an audio file included in a Bandai Namco video game. It contains a collection of audio referenced during gameplay, such as background music and character dialogue. Most notably, NUS3AUDIO files are used in Super Smash Bros. Ultimate, a popular fighting game for the Nintendo Switch.

More Information

While most video game players will never encounter NUS3AUDIO files, some Super Smash Bros. enthusiasts enjoy extracting, playing, modifying, and creating their own NUS3AUDIO files. These modders have developed programs that allow them to manipulate and create NUS3AUDIO files, so they can add custom music and dialogue to Super Smash Bros. Ultimate.

NOTE: The NUS3AUDIO format replaced the .NUS3BANK format used in Super Smash Bros. 4. Super Smash Bros. Ultimate contains NUS3BANK files, but those files are used only to set audio parameters, such as volume.
