Fuzzmeasure pro 3 serial5/17/2023 ![]() ![]() but no excuse!) It is the level of the reflections relative to the direct signal that prompted me to comment regarding the RFZ! As you aspire to this level of absorption in the ISD gap! -)īut I might recommend you isolate each of the later arriving paths and use your absorption to treat them. As each vertical gain graticule is 10 dB (I think this is what sidetracked me above with the time graticules. The remaining reflections are ~30 or more dB down, rendering them 'insignificant' relative the the direct signal. Take a look at the attached annotated ETC for updated arrival times and corresponding distances. My comments in large measure still stand. And I doubt it it 45.6 ms, as that would mean that the mic was 51.5 feet away. So your rig has a latency (propagation delay) of ~45.6ms.as I cannot ascertain the actual zero reference point relative to the speaker itself to determine the distance of the mic from the speaker. Yes, in my rushing around and playing with this on a portable while traveling (I know - braindead.) I misread the scale. And later arriving reflections from an uneven rear wall are comparatively rather easily addressed. ![]() This would provide symmetry for the early reflections greatly impacting imaging. I would heartily agree with Ethan regarding moving the speakers to the window-wall. But the attached procedure, assuming FM does not auto-generate time/distance calculations allows one to identify the particular paths and reflection incident points without difficulty. Not knowing the exact placement of the speakers, it is difficult to identify a reference point from which to speculate about the specific reflection origins, be they side wall, irregular work surface (and possibly ceiling, and various sidewall surfaces) in the irregularly shaped small room. One can try damping the work surface, but I suspect a reorientation of the workspace is the fundamental solution where the work surface is pulled further from the wall and the speakers are mounted behind the surface and the where the work surface is isolated similarly to how pedestal mounting of the speakers relative to a large mix console where the negative angled direct signal dispersion is absorbed by the back of the board rather than being reflected off the work surface.īut this change is not trivial and will encounter objections from those who place convenience over function.ĮDIT: End edit The work surface will create a significant early reflection that will not only impact intelligibility and skew the image, but you will have significant comb filtering and polar lobing in the direct signal. ![]() In reference to the speaker placement, this is a fatal flaw that is all too common in such workstation/table oriented environments. Otherwise it seems to say it is overdamped and on its way to being an RFZ except for the early order reflections.Īlso, it would be nice to have additional 'detail' for the time less than 50-60 ms. There should be more significant reflections that are less than 25-30dB down relative to the direct signal assuming that this is still a 'to be treated' room. I will note that I have questions regarding this measurement. ![]()
