Ah, but my objection is that those are proprietary systems, and I
would much rather not use any. Part of the appeal of Ambisonics for me
is that it's freely usable by all and no licensing is necessary.
Yup, same here.
That's actually really very important to me, I'm afraid. I have no
issue in principle using commercial software that decodes something
that is an open format; I do have issue being locked into a format or
protocol that is not in the hands of the public.
Openness is crucial for me. That plus "portability" as mentioned in the
thread. I find it very convenient to not be tied to a particular speaker
arrangement when composing or performing, and just decode to whatever is
available in concert. Software like ADT makes it possible to design a
"reasonable" decoder on the spot if needed.

I understand - most of my stuff is site specific so thus my views. If
scalability and portability are important to you - you might also want to
check out Dolby and DTS's competing new object based 3D audio software -
no idea how easy it is to get your hands on Dolbys - but DTS should be
approachable. DTS say their system lets you put in the speaker array map
and then the file adjusts to the array - so one file is compatable with
multiple arrays., not sure about Dolbys.

I have found amplitude planning effective in some circumstances, but I
find that it's not portable, e.g. I can't deploy the same to a
different speaker arrangement, and I can't scale it down to a smaller
array while composing, among other issues.
I did funnily enough do some basic experiments with Distance-Based
Amplitude Panning with reasonably good results, I just haven't gone
much further. I've used it in some site-specific installation work to
good effect, but again it didn't strike me as being particularly
scalable or portable, hence why Ambisonics is still my first choice.

Out of curiosity - can I ask why you want to use ambisonics as
opposed to
other spatial audio techniques ?
I'm not sure how to answer. What other techniques did you have in
mind? The reasons are several: I understand at least to some extent
Ambisonics, and I have some (but limited) experience doing it in a
planer array; Ambisonics are flexible and scalable; compatible with
some B-format that my colleagues and I have realised already and will
create in the near future; and can be implemented in the software that
I use (largely PureData and SuperCollider.)
I don't really see which techniques seriously compete with Ambisonics,
but I'll very happily check them out if you point me to them.
