Hello,<br><br>I've read <a href="http://xiph.org/ogg/vorbis/doc/stereo.html" target="_blank">http://xiph.org/ogg/vorbis/doc/stereo.html</a> and the Vorbis specs, but I haven't got a clear concept of how does the Square Polar Mapping works. I mean, in the "Ogg Vorbbis stereo-specific channel coupling discussion" document, it's described how the decoupling process works for Square Polar Mapping (and it is fairly clear explained), but it does not describe how the coupling process works. I've found another thread of May 2003 asking the same question but it neither gives a clear answer, and googling it I've had the same (no) success. <br>
<br>In short, what I'd like to know is how, having several (two for simplicity) uncoupled channels, how does the square polar mapping does to get the associated square polar notation?<br><br>Thanks.<br>
