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.
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.
