Is there any guide or youtube video that gives an in depth tutorial on what you're looking for with room measurement graphs? I read this realtraps.com/art_measuring.htm and while it gave me a guideline on what to look for, it didn't quite tell me how to read the charts for myself. I have a general idea of what I want to see on the graphs, but I haven't found a video tutorial that teaches me how to interpret for myself. Specifically, I was looking at the placement of my bed in my room. I wanted to see if having it centered or more towards the left would change anything. It appears that moving to the left made things a bit worse in ranges that don't matter too much (0-30hz), but overall the graphs seem about the same except in different locations? Idk. It also looks like there's a null in the 100 range, adding bass traps to my room will solve that right?. I've added the attachments below if anyone wants to take a look. I measured with both speakers on simultaneously (not individually done) with my mic on a stand.

I'm pretty sure I went into this in my recent Worksheet video. Really, it's as simple as seeing how far the squiggles are from center - center being your reference level. That's part of the reason you smooth the full SPL - to see what your base level is. From there you can compare on a frequency basis how far off you are. Decay is similar and that's why I like the decay plot over the waterfall graph.
Edit: Maybe I need to do a video on exactly how to read the graphs. I thought I made it clear. Maybe you can let me know.
Thanks.

guppy, Did you took unnecessary things off the room? One thing, measure ONE SPEAKER at a time, then L+R together. Both speakers at the same time is only useful to look your bass response, nothing more.

I watched that video beforehand and I wouldn't say it taught me how to interpret the graphs, it just gave me a general sense of what might be "good" or "bad" in a graph.
Yup! Those two graphs were with everything unnecessary out of the room. And that's good to know, I will do it again.

Ok, thanks guppy. Maybe I can make a video more focused on reading and adjusting the graphs themselves. Thanks.

Do new measurements, point the measuring mic straight to the ceiling, check that its at tweeter level and do 1 speaker at a time.

Yeah, your guide is still good Hexspa. It's rather useful, but sometimes I feel like I missed the prerequisite course "basic basic acoustic for drunks:.
Pasim, it is. It should be pointed at the ceiling? I just pointed it between the two speakers.

Yes, you should point it at the ceiling, which measurement microphone you have ?

Sorry for such a late reply!
I'm using the "SONARWORKS Calibration Measurement Microphone for Recording Studios", basically the one that comes with Sonarworks Reference 4.

You just moved your bed? Some changes don't make big differences. Look at both SPL and decay. Use measurements from Ethan's stickies or ones I have on my worksheet for examples on how to usefully display the information. Specific questions are better otherwise we have no idea what you do or don't fully understand.
