[vorbis-dev] PlusV algorithm

do you have a pointer to this plusV algorithm?  Is it similar to SBR?  My understanding is that Coding Technologies has core patents on the SBR algorithm and similar types. is plusV known to be patent free?

        Well, I've seen the old discussion about the SBR, and I don't agree that Ogg is comparable to Mp3Pro. Ogg easily beats Mp3Pro at medium and high bitrates. But Mp3Pro is FAR better at low bitrates <=64 kbps. All benchmarks say that Mp3Pro is the very best codec for such bitrates.
        
        What is Mp3Pro? It is Mp3 for low frequencies + SBR for high ones. Ogg (better than Mp3) for low frequencies + PlusV (better than SBR) for high frequencies - might be the best codec for lower bitrates too. Sounds cool, doesn't it?

        Thank you.
