I am currently in the process of building an
eight-channel ambisonics
setup in my home-office. Size is about 3x3x2.5 meters.
With the currently finished 4 channels the surround is good. But it still
has problems with imaging the sources. Originally I was thinking about
six channels in the plane and two over-head to have a half-sphere. But I
will definitely try eight-channels in the plane before. I think it will
sound better then six channels...
So if you want anything more then 2D, you have to get more then four
channels. As a bonus this will also sound better with the 5.1 and 7.1
movies:-)
wow. That sounds ideal! What software are you using to accomplish this
and how? ? What sound card are you using and are you using an external
d/a converter
The hardware is my firepod which has eight analog outputs, connected to two
active alesis monitor speakers and a self-made 6-channel amp with 6 connected
jbl monitor one.
For the software I am using:
- jconvolver to correct the sound with pulses calculated by drc with impulses
measured with aliki.
- ambdec to convert from ambisonics to the specific speakers.
"Normal" music listening I do without ambisonics as I don't have the
additional speakers powered on all the time. But it is also nice to use the
ladspa stereo-to-amb panner to move the stereo speakers in the room.
I am thinking about adding a 5.1-to-ambisonics mixer/panner to move the
specialized channels with their defined positions to virtual sources in my
ambisonics surrounding. Don't know if that works out...
Have fun,
Arnold
