Yes, it is proprietary. AFAIK Yamaha don't really support it any more,
because much of the technology it uses ended up in AAC, which is a better
choice for low bitrate stuff anyway. (Public format AND better sound
quality).

I dont know much about VQF, but I think AAC is more closely related
to MP3 technology: They changed the transform sizes and got rid of some junk
that MP3 inherited from layer 1 and 2, but it is basically encodes MDCT
coefficients with the MP3 critical band/scalefactor approach.
