By that title, I don’t mean the capabilities of the Wii title called Wii Music*. The video below, from Dublincalif, is about the properties of the Wii’s sound system itself. It’s 24 minutes, but pretty interesting for all that, and it’s presented really well. It’s a model explainer video, and a great first effort in that style from its maker!
You might think that all the music on the Wii is just streamed, either from audio tracks or files, but it isn’t. The Wii has fairly little NAND storage, and music is a major consumer of storage space, so a lot of its music is sequenced, essentially MIDI files played with sample banks, with optional effects added. The video is a great overview of its features and capabilities.
* Of random interest: Wii Music’s data is amazingly small! Of that 4.7GB DVD it resides on, it uses less than 10 MB!
