[CM] ambix ambisonics command line

[Anders Vinjar]

btw, a big thanks from me also to Bill, and Rick Taube, and their
extremely succesful software, used for more than 30 years of composition
work.

Also fellow cmdist'ers - kind follow-ups and gentle ways of solving
DSP-mysteries, my general lack of DSP-knowledge etc.

An anecdote: in the early nineties, fellow-students struggling with
limitations and bugs in Protools, me trying to get my head around
text-based Music-V and Lispy CLM: an initial question on cmdist, a
polite personal answer from the developer (with a "thanks for the
bug-report!"), and a new version of CLM the next morning, solving that
riddle.

Wonders of Open Source/Freeware and pro developers!

Thanks!
