I use 16 speakers in a dual hexagon(up and down).  I think that spacing at 45

Isn't this a dual octagon? ;-)

Rest assured...

 I think the corners are bad because of the time differential between the 
speakers i.e. length of the radius from the center.

actually contact this guy he did exactly what you are saying in Max :

also Nuendo new versions allow for it (amplitude panning based not
ambisonics)

I would use four at ear height or a bit lower even and four in the corners
of the room or - a cube starting at ear height. However you could also mess
around with some of the DBAP (distance based amplitude panning) max
externals which let you tell the system where the speakers are and then pan
around them - you can have all sorts of weird and irregular speaker arrays
- no need to stay peripheral - depends what you want to do I guess:

by the way its easy to do exactly what you are suggesting with
ICSTsambipanning~  or any panner which allows for multiple soundsources and
recordable trajectories (automation)

Hello all,

I'm looking into experimenting with live 3D panning of sound tracks

from a

DAW. The tracks will not be in B-format as I do not have a soundfield

mic.

I have 8 identical M-audio AV 40 speakers which I will be driving

through

an interface and Max/MSP code (
http://www.icst.net/research/projects/ambisonics-tools/).

The comment has already been made: You don't need a mic to make digital
audio ...
For ambisonics, anything other than first order must (almost) certainly
have been created (with or without mics).

I'm primarily interested in taking a mix for my speaker array and being
able to tilt / rotate / reflect etc. all of the tracks simultaneously.

That sounds like ambisonics,
but I would (for ambisonics) phrase it as: Making a mix fo any speaker
array, being able to tilt, etc., and being able to listen to the result on
'any' array ... including my own.

- Any advice on speaker placement for 8 speakers in a small bedroom? I'm
currently thinking the 6 corners of a cube and then left and right on

the

wall at ear level.

Think we'd need to see the bedroom .... or at least hear about it ....

Eight sounds like the corners of a cube (you mention six ... that would be
the faces, and not as 'simple' to deal with (nor (?) anything like as
good)).

- Are ambisonics techniques the best/only way to do this given that I
don't
have B-format?

Everyone with a computer 'has' B-format ;-)>

- Any references that would be good for a newbie to read? My background

is

in math and programming, so technical material is fine.

Good luck,

Michael
