@daphy: Thanks for the initiative.
As a 1st contribution, I'm adding a newly designed bidule which uses the
Panorama-VST. It's currently in the "/Ambisonic/upload"-directory, but you might want to sort it differently.
Some explanations:
Code:
I think it basically achieves the same as
the 'old' one. Maybe it is slightly better, as it
processes internally as 2nd-order-B-format (within
Panorama), whereas B-Pan "only" does
1st-order-B-format processing. I don't yet have
enough samples to really call this a "firm" statement,
so it's just a working assumption currently.
Some notes to the settings (see 2 attached JPG's for
illustration):
(1) Elevation: I put that from 0 to 0.55 (L & R), to
tilt the soundfield slightly upwards by 33 degrees.
This is because my speakers are all very close to the
floor.
(2) Distance: I out that from 3.70 to 5.05 (L & R),
which slighy enlarges the size of the sound-sphere. If
enlarged too much, the VST calculates too much
reverberation for my taste.
(3) Azimuth: For "L", set to +2.20, for "R" to -0.94.
This only applies to when decoded to Pentagon.
For Square-decoding, it would be +1.57 for "L", and
-1.57 for "R".
Why the change (Square --> Pentagon) ?
- "L": +1.57 --> +2.20
- "R": -1.57 --> -0.94
Remember that we turned the soundfield
counter-clock-wise by 36 degrees, inorder to have it
correctly aliged to the 5.0 (or 5.1) speakers in people's
living-rooms.
We have to do the same here, i.e. rotate
counter-clockwise by 36 degrees, which corresponds to
an an increase of +0.63. Meaning:
- "L": +1.57 + 0.63 = +2.20
- "R": -1.57 + 0.63 = -0.94
Comments & suggestions welcome here in the forum.
Happy Xmas to all
