Web-based BRSTM player

Just open the demo in modern browser, select a .brstm file, and enjoy!

What Is BRSTM?

BRSTM is a file format that contains audio data that's being used for some Nintendo consoles. One of the differences with the usual audio format (MP3, etc) is that this format can contain a loop point, making it suitable for usage in games.

.brstm file is not included in the repository.

Some places to look for BRSTM files:

• Smash Custom Music^{[dead link]}
• Smash Custom Music Archive (the audio player in this site is using the "brstm" package from this repo!)
• Reddit
