Many Nintendo video games include BRSTM files. Most notably, Mario Kart Wii and Super Smash Bros. Brawl use BRSTM format audio. These games' fans have created utilities that allow them to extract, play, and convert the audio that BRSTM files contain.

Gamers have also created tools that allow them to create custom BRSTM files. For example, Brawl Custom Song Maker can convert .WAV, .MP3, .OGG, and .FLAC audio files into BRSTM files, which savvy gamers can import into their video games.
