Hello

after measuring a small room I don´t how is the spectrum (well or bad)

if I open zoom a lot in smartlive I see horrible peaks and holes

What is the correct zoom I have to put in smaartlive to see accurate?

and too you can comment how about this analizyng is...

Regards

and here with a small zoom

those pics are bit big. you'll want to resize them I'm sure.

what part of the program are you having trouble with exactly? If you call the folks at smaart, they're always really helpful I've found. You paid a lot for that program and they want you to be able to use it.

in special 43hz I have a big resonance

room is 3,75 L x 2,65 W x 2,54 H

I don't use that particular program, but if possible you should only look at frequencies below about 400 hZ; above that, anything you move (like a mic stand, chair, etc) will change things.

Also, the graph means nothing without knowing exactly where the speaker and mic were placed in the room; to minimise placement effects, speaker should go in one lower corner (as close to the corner as physically possible) and mic (omni only, NOT directional) should go in the opposite, TOP corner of the room. This will tell more about the room itself.

Then, once you know what the room is contributing, you can place speakers at desired location (plane symetric location vastly preferred) and check at listening position. Any increased dips/peaks are caused by things like SBIR, modal peaks/dips. You do NOT want either your ears or speakers (center of woofer) located dead center vertically, this just adds another modal peak/dips to the problem. Either above or below center by 4-8" (10-20 cm) is best for a normal room height; see the sticky
