Thanks. I'm not clear, yet, how to read the spectrogram very well, so I'm searching around. But this is very helpful!

Hi all, I'm looking to either buy or build some skyline diffusers for my room, especially the front wall. However, before I spend the money or the time, I need to know what specifically needs help. I've used impulse graphs extensively, just looking at the range from .03ms to .14ms and seeking...

Thank you, John. I've done this for about a year at this point, and don't expect flatness. Your advice about gauging the relative shapes — the drama of troughs and peaks — is well taken. The reason I'm asking is that as I move things in the room to gauge better and worse, it's sometimes hard...

Understood. I don't really know when I'd need to align them -- that's the fundamental issue. I'm probably too novice to be using a tool this sophisticated!

Thank you, John. Then I need to do nothing to calibrate those graphs to align them -- just read them as is? Is that what I'm to infer from your remark? Thank you.

Hi all, I've searched a bit on threads and don't see the answer to this, though it's probably out there. I just built a room and am doing sweeps for 2 channel. TASK: Taking measurements to optimize speaker placements of speakers and listening position. ISSUE: The starting points of my SPL...

Hi Mark, I love your comment, "The gear acts in some part like an extension of the body itself." In addition to the telephone, one might add the gun or car -- in the sense that it aggrandizes the power and, thus, the (ostensible) authority and value of the owner. An ego-ploy, no doubt, and there...

Thank you, Grayson. The smart people on these forums have done so much to educate me. I'm very grateful.

Recently, I made a video about audio and philosophy. This was originally presented last month, at the 2021 Society for Philosophy of Technology conference. The video was then featured on Paul McGowan’s blog -- huge readership. Today Hans Beekhuyzen has done a video linking to mine and then...

Great. So -- this will be my last question, and thank you for your forbearance -- so when I'm looking at two curves, and comparing them, and one starts lower or higher than the other, you're saying that what I need to do is assess them based on their shape (relative to flatness)? I only want...

Thank you, John. Does your answer imply that I do *not* need to adjust the measurement in order to compare it effectively with previous curves? Or should I line them up?

This is a question about why new SPL measurements don't line up (at 20db) with previous ones and what to do about it. Here's the situation: I'm using REW to integrate a second sub. The subs are Rythmik F12SE and have a number of controls that I'm adjusting. I'm varying "Delay/Phase"...

Permission to think that: granted. Good point.

Thank you, JLM. One suggestion I got recently about comparing nulls or peaks within a graph is to try to correlate them with which note they correspond to. If a null, for example, is at a place where there is no note in our tuning scale, it is less important to fix compared to another similarly...
