Want to try omni - Am I on the right path, or where do I go?

Thanks. It also works the other way around. Small panels can be used to redirect reflections.

By the way, I would also do band limited ETCs.

Of course. Or some diffraction devices. There are many ways to skin ...

I prefer Elias' wavelets now. Give me all the bands at the same time.

Hello everybody,
I am a newbie, I hope I am addressing the correct post.

I have a loudspeaker array of 4 small speakers (each one as big as a Rubik's cube), linearly equally spaced by 2 cm (0.8 inches). I would like to play a sound source (pink noise) from the first to the last speakers, to give the illusion of a moving sound source.

One trivial solution would be, for right-to-left movement:
0 0 0 1 at time t
0 0 1 0 at time t+n
0 1 0 0 at time t+2n
1 0 0 0 at time t+3n

But this obviously gives me the impression of sound "jumping" from one speaker to the following.

Another solution would be updating the intensities twice more frequently:

0 0 0 1
0 0 0.5 0,5
0 0 1 0
0 0.5 0.5 0
0 1 0 0
0.5 0.5 0 0
1 0 0 0

but I am not sure it is the correct way.

The question is: which sound intensity should I set the speakers so that the sound is "smootlhy" perceived as moving?
I guess this is related to how to create a phantom image.
Please help!

Thanks a lot!

Coming in from the left field (as usual), has anyone here mentioned the Shahinian speakers as an alternative design idea? See pics below.

Enjoy,
