Well I tested with my denon mic. Turns out that after EQ'ing everything sounds flat, no life in it. Low notes sound like they are EQ'ed out, not pleasurable to listen to, very "cold" sound.

Maybe I'm doing something wrong. In the examples you see the lows in the graph fade out to the  unhearable range. In my measurements they are quite high even in de 20hz range.

When I turn the slider up to the point the lows are unaffected (quite high) it restores, but it also gets back more to the original tone of the setup, so I think I am eliminating a part of the calibration I just done.
Also i put the mic on a one-foot tripod at ear height and put the children to bed (that helps a lot!)

Is there someone with a little more experience that can help me out?

At this moment I am already getting more pleasant result by playing with the settings, but it's quite difficult. Maybe there are some tips or do & don'ts to consider :)

I'm getting the hang of it....

This plugin is fantastic  :o  :o  :))  :))

I thought I had tuned my set quite good. After turning off the plugin, everything seems more boomy. Also the highs are much more dampened.
Love this thing. Soon I'm getting myself a good measurement microphone. Only need to find out now how to import the calibration file in this tool... I have no idea yet.

Interesting, what about a VST multichannels version?
You can use multiple instances of Room EQ VST in your DAW.
That is obviously not the case in foobar2000, which is OK by me. I just have a question about it.
I just started using the Room EQ plugin in foobar2000 in combination with a 5.1 channel setup. No problem, I'd like to know if Room EQ in this situation only affects the front L+R channels?
In theory, there is no difference between theory and practice. In practice there is.

A little update. I did use a calibrated mic short after my post, but found that the sound after calibration was still not quite how I like it after listening more thoroughly to it. The boomyness was fixed by putting the outer rings of the bongs into my CM10 s2 speakers. It fixed that perfectly.

After trying with and without calibration it somehow not quite satisfies me. Maybe I like the signature of the B&W speakers the way they are, but then again calibrated should be de point to start. Tried many different settings but still I miss something. The low end is a bit too suppressed. Maybe this comes from a slight hum from my aquarium pumps (50hz). I don't know if they influence the measurement? It's barely noticable, but to a microphone maybe more??

Are there any suggestions or alternatives to this to fool around with?

Meh, another update without changelog.  ::)

Hiyas, can I measure a purposeful profile using builtin laptop mic or do I need an external studio microphone?

The built-in laptop mic has a non-linear frequency response and its directional pattern is not suitable for this application. You need a conventional measurement microphone. They are not expensive.

Thanks k2k for this wonderful piece of software, very user friendly. I recently bought a UMIK-1 for setting up the foobar DSP.

As someone who is new to room correction, I have a few questions;
What volume in decibels (approx.) should my speakers output while running the measurement?
How many measurements should I run if I have only a single static listening position?
Does mic placement make a big difference in terms of height and angle?

[...]

Is there any reason not to start with your listening volume and the listening position? 

(If height makes a difference in terms of sound, then mic placement will placement will make a difference too, of course.)

REW suggest 75db + (take care for clipping if going up).

Moving the mic 1" will change your measurements. There's no consensus about mic placement up or forward, so do what suits you.

I take one or two measurements before changing something in my room. There's chances of having weird measurements or noise during a sweep.

Does the software offer the option to correct only below the Schroeder frequency of the room, as per the recommendations of Toole and some others who assert that 'correcting' above that may be detrimental.  Below Schroeder, room modal effects dominate; above it, reverberant effects dominate.   For 'typical' rooms it's circa 300Hz.

If you don't wish to correct the frequency response above 300 Hz, use the manual correction of the curve. Use the left mouse button to draw arbitrary curves, or use the right mouse button to draw straight lines. The statement about the influence of the reverberation effect is correct, however, Room EQ applies an advanced multipoint measurement algorithm that takes this effect into consideration. You may want to compare the different types of correction with your own ears (use the "Save preset" and "Load preset" buttons to conveniently switch the plots).
