After a Google search I found this:

I'm just guessing but, it's possible that Spacesizer may just be a funky name for one of the many ways of recording music so that more than just stereo is extracted by the playback system.
Due to the lack of search engine hits it's obvious the format never caught on.
This link shows a picure of the record or CD or whatever it is:

A UseNet newsgroup search didn't find anything.
Sheeesh!!!! Even obscure weird stuff gets at least a page or more of search engine hits. That Spacizer thing must be really obscure!!!!!
