Using its staggered 4-mic array, my Trinnov Amethyst captures data in multiple domains, including height/distance azimuth, phase, timing, and frequency. Let me try to dig up some screenshots to demonstrate how the AVAAs have been effective in reducing undesirable room resonance (mostly in multiples of 35Hz) present in the rectangular space (extension of my lining room into the balcony) to the R of my R loudspeakers.
I just picked up the PSI Audio line for my audio business and have 2 in my 26'x17'x8' audition room. They really are interesting and have made quite in an impact. I have found that placement is a bit tricky and not what I originally thought, but the results are very good. If you are in the Mineeapolis area, come over and play with them yourself!
