[CM] ambix ambisonics command line

[Juan Reyes]

Hola Nando,

Thanks a lot for responding.

Tried looking for '.tetra' files on Fons site but could not found any.
However, I tried 'theoretical.tetra" and results were not that bad.

Using four channels sound files with no microphone at all.

FTR, workflow I'm using is combining four channels to get A-Format
signals in aa Snd instrument as:

W = FLU+FRD+BLD+BRU
X = FLU+FRD-BLD-BRU
Y = FLU-FRD+BLD-BRU
Z = FLU-FRD-BLD+BRU

Once I have these files, I use Fons' 'tetrafile' command to get B-format
soundfiles with something like:

'tetrafile theoretica.tetra a-file.wav b-file.amb'

Is there a way to get more '.tetra' files ?. Would be great to do more
experimenting.

I really appreciate Anders pointing out this method because 'tetrafile'
command can be embedded in a script to do batch processing.

   Best of all!,

   -- Juan
