.brstm is an audio file type that is commonly used on the Nintendo Wii and GameCube videogame platforms.
Question: Is BRSTM a lossy or lossless file type?
Although I've tried finding out through my own research, I haven't been able to determine much on this question:
Although Wikipedia has no article on the subject, it mentions the term on the page, List of File Formats under the Lossless Audio header.
However, the reference it cites, What Is a BRSTM File?, makes no mention of it being lossy or lossless.
Additionally, the BRSTM technical page on the WiiBrew wiki, among the references of the above-mentioned reference, also makes no mention of it being either lossy or lossless.
