Re: [Sursound] OZO?

Remains the question of _how_ to actually use the available signals to produce anything surround. Linear beamforming is limited to LF (due to aliasing). The only way I see is some rather complicated non-linear 'logic' decoding. This kind of thing is still a research topic. They could apply
