Yvan,
I would say yes, definitely, to both parts of question 1, both input and
output capabilities would be useful.
A normal workflow might go something like this:
- record A-format (direct mic signals) in the field
- Main project:
+ read the field recording in its native format, multi-mono, etc.
+ edit into tracks, do heads and tails, assemble tracks into a whole
+ apply some kinds of processing either surround, like rotate, or not
like EQ
+ possibly mix in other material via ambisonic panners
+ render to a master B-Format track, to be stored in an .amb file
- Decoding project:
+ read the .amb file from the main project
+ decode to the delivery format(s) like stereo or 5.1
+ repeat for other delivery formats
If everything is in the same workstation, like Nuendo, then it doesn't
really matter if the intermediate storage is a single .amb file,
multiple mono .wav files, etc. However, if we use .amb then we can play
that file in other software in more predictable ways, for example my
VVMic will switch out of A-Format mode if it detects the GUID on input.
It will also write the GUID if set to B-Format output.
In Nuendo, on input files it might be nice to tell the user that the
GUID was detected, but it's probably not important as long as Nuendo
will go ahead and use what is also a pretty normal multi-channel .wav
file. I believe this works fine today, though putting .amb in the
extensions list would be a nice touch.
On output, unless Nuendo were modified to have B-Format be a bus type or
something like that, then I can't see how you would automatically detect
that the output was supposed to be B-Format. There could be some kind of
option in the render dialogs to allow the user to say that they want the
GUID included or include it if the user names the file with the .amb
extension. Might also need logic to only include it for multi-channel
files.
Question 2: Yes there are some VST's that do B-Format panning and work
in Nuendo, in particular I have used Bruce's and the Swiss Center B-Pan.

Hi
1)
i want to known if it makes sense for an application like Nuendo (Steinberg) :
- to import directly (without decoding) AMB (Ambisonic) Files (described in
http://dream.cs.bath.ac.uk/researchdev/wave-ex/bformat.html)
- to allow to export them directly (no Encoding)
This means that the Nuendo file selector will display as readable file, files with
extension ".amb"
and the same for export ".amb" is selectable as format.
It would be great if it makes sense to have some use cases...
2) are there some Ambisonic plugins which could be use as Panners in Nuendo ?
Thanks a lot for your time
YVan
