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!
