Post Subject: Window vs sweep durationPosted by martinshorn on: 3/12/2018
Hi Daniel. I mean the window, after you sweep 10 seconds, and fuzz shows the IR. You can change the IR windowing on the preferences panel... like crop/cut the analyzed part of e.g. 1ms before the peak and then duration X behind the peak (here i asked for 1msec). That can exclude reflections on long distance recording of high frequencies (on the expense of resolution, so no smoothing anymore). You can also drag that crop with the mouse depending where your room actually starts reflecting (look when the second small spike after the peak appears, that one is to be cut off).I was just curious if the 7-8k Spike is the titanium breaking up, the old fashioned phase-plug or maybe an effect of nearfield-mouth measures. But it looks like too much the same even without window/smoothing change etc... No need to try! I can see its really there. Im surprised how amazing it actually sounded in Klaus Speth' installation, crossing this at 6.6k !!!!!!Reminds me of the Goto statement "you shall not measure, you shall listen". Which sounds like stupid marketing in the first place. But for second time (first was compression driver in bass) Goto seems to bend the physics successfully. Very funny!
