About BRSTM files
The .BRSTM file format is a proprietary audio stream container developed by Nintendo for the GameCube and Wii consoles. It primarily stores in-game background music and audio effects, featuring native support for seamless audio looping points. Community modding tools like BrawlBox or VGAudio are typically used to extract or inject these audio files into game ROMs. The main disadvantage of the .BRSTM format is its rigid incompatibility outside of the Nintendo ecosystem. Standard media players like Apple Music, Windows Media Player, and web browsers cannot natively open or play .BRSTM files. Furthermore, because these streams are optimized for older console hardware, they often lack modern compression efficiency, resulting in unnecessarily large file sizes. You need specialized software or plugins just to listen to the audio track. To make the audio usable, conversion is highly recommended. For universal playback and sharing, convert to MP3. If you are a game developer or video editor needing high fidelity, convert to WAV or FLAC. For web developers seeking a balance of size and quality, OGG is the best target. Drag and drop your file here to analyze and convert it - free, online, and without installing software. Note that converting to standard audio formats will typically strip the proprietary embedded loop point metadata.

The BRSTM Converter Story
The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our BRSTM converter.
