Now there's a subject and a half. Ambisonics is *different* to 5.1 and has
advantages and disadvantages (mostly advantages IMHO). Much of the power of
Ambisonic encoding is that you can find an optimal decoding strategy for
whatever speakers are available and you don't need a hardware decoder (there
are a number of software ones included in the CMT plugin set).
Anyone wanting to find out about Ambisonics might be interested in taking a
look at http://www.muse.demon.co.uk/3daudio.html.
