He and I have never understood the general obsession with > decoding matrix quad in real time. Do it well and do it once. Yes. Originally, of course, the assumption was that it would come via something like an LP or broadcast and need to be done 'real time' whenever it was played. But nowdays the only drawback of 'decode once, properly' is the load of storing larger (output) files as they have four channels, I assume. I'd assumed there were now some open source decoders available that do the trick. But my interest in 'surround sound' is pretty low, so haven't really paid much attention.
