also you could use rew to eq each individual speaker.
For eq'ing speakers I use DRC (Digital Room Correction), it is free
software. Once you have measured impulse responses it will create
filters that eq the speakers, tons of parameters to tweak if you need to
(no gui, just a command line thing that is easy to script).

There's not much
point time aligning DBAP because time align to where ? The beuaty of using
amplitude panning with irregualr speaker arrays is that there's no sweet
spot, especially for walk through installations.

Its a crude work around - but it works if you dont have time to learn
ICST. You can also try jamona.

I use ICST in MAx MSP for irregular speaker arrays and it works fine even
though it says its "Ambisonics equivelant panning" if you reduce the
directivity it basically works like a form of DBAP. It works really well,
Ive made sound sfly through mazes and up and down buildings with it. You
can even use a normal octaphonic panner to make things fly in a straight
line - at the end of the day the sound is traveling from one speaker to the
next - the software doesnt know youve placed the software in a line rather
than a circle.

Hey everyone,
I’m having a bit of trouble setting up a SPAT Revolution session for an
irregular speaker array.
1. I am working with an irregular array of speakers for an installation
(see attached, speakers numbered 1-12). The speakers are in a long hallway
and are irregularly placed in the x, y, and z planed though always
overhead. I would like to have sound move with each walker as they pass
through the hallway by automating sound to move at average human walking
speed. I am using Speaker 7 as an origin point (0, 0, 0).
A. Which is the correct pan law to use? I have tried DBAP and KNN but
the diagram of each speaker seems to be pointing in the wrong direction,
esp. at the origin. I would like the speakers to point down towards the
floor.
B. Is it advised to select a single speaker as the origin point?
2. I have taken surround impulse responses from an array of 7 speakers
in a surround setup approx 19m from the origin. The microphone array was
7+4 (height) at 1m from the origin. If spatializing in SPAT, would I make
the convolved signal 19m from the origin (where the speakers played the
sweep) or 1m (where the microphone array was).
3. In either case, would I compute speaker alignment or normalize?
4. Are you aware of any products that can calculate multichannel
irregular speaker distances/correction curves from a test signal? Something
like sonarworks or genelec SAM but not proprietary and with the ability to
calculate actual speaker positions from test signals rather than having to
scan the room (which I currently do using matterport) or measure by hand.
Thanks so much,
Jon
