Web-based BRSTM player

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

What Is BRSTM?

BRSTM is a file format that contains lossless 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
