@zhacker No, there is no decorrelation algorithm operating under the hood. Each input of a Spacemap system can use the same or different Spacemaps. For each input, as the Spacemap Panner (which represents an input) is moved relative to the nodes in the Spacemap, the levels change at the cross-points of the Summing Matrix of the GALAXY, changing the level of the input signal routed to the system outputs. There is no decorrelation inherent to this function, though loudspeaker locations and listener locations can be great enough for decorrelation. The Delay Matrix of the GALAXY is post the Summing Matrix and there is a delay on each output as well. These can be used to decorrelate a signal by adding enough time offset, if desired. You can test this by setting up two loudspeakers, locating a sound between two of the loudspeakers by moving the Spacemap Panner between the two speaker nodes, adding delay to one of the Delay Matrix cross-points or to one of the outputs, and moving the Spacemap Panner between the nodes to observe the subjective result. Does this help your understanding of the app? Anyone else have some thoughts?

Thank for your detailed content.

I think this non-decorrelation will be beneficial when the input is moving, it will induce less artifacts right?

I’m just curious about, when all of my inputs are nearly static such as  orchestra stems , how does each stem sounds like through 3 or 4(maybe totally frontal 7)hangs of arrays(let’s assume that the input as well as the stem ,is sitting at the note which have already connected with related arrays), will it cause a audible comb filter effect in audience?

@Wenzhao, Yes, multiple arrivals of correlated signals, at different times, if they differ in level by less than 18 dB, will result in noticeable combing (some say 12, 9, or 15 dB level difference). Relative level between the signals determines the amount of frequency response ripple, maximum ripple = relative levels match, less ripple as the relative levels diverge. The time offset(s) determine which frequencies will add and cancel.  You're thinking about the correct issues.
