How do you use it? How do you set the "Q" is this the same as envelope?
 
Presto,
This helped me to understand "Q". My layman's understanding is that a Para EQ allows you to target specific frequencies to cut or boost. A tool for precision surgery on a signal.
Hope this helps.

[The "Q" allows you] "the ability to alter the bandwidth [or ‘Q'] over which the cut or boost will be applied. ‘Q' - standing for 'quality' - is an alternative term to refer to the width of each EQ band, where high Q = narrow bandwidth, and low Q = wide bandwidth."

"The Q set at 1.0 means the cut or boost will affect 1 1/3 octaves from the centered band. If the Q is set at 3, it will boost or cut "1/3" octaves from the centered band."

"Q Setting Chart:

Q Setting Bandwidth

0.7 = 2 Octaves
1.0 = 1 1/3 Octaves
1.4 = 1 Octave
2.8 = 1/2 Octave "

Just to correct Dale's post, setting the Q to '3' will give a 1/3 octave bandwidth (not 3 octaves).

Dale fixed the error, ignore this post!

yeah i have this PDF file thats helping me wrap my head roun all this stuff..My problem is I can`t find how to do it in Reaper...when I open the parametric EQ it just shows 3 faders no band graph at all..
 
Try turning the gain up 12dB, the Q or width up all the way and move the frequency around. Now set the Q or width all the way down and move the frequency around. After that turn the gain all the way down and repeat the other stuff with Q/width and frequency. A graph helps but what will matter in the end is how it sounds.
 
Presto,

I think you are using the JS:filters/parametric_EQ. I use the ReaEQ. You can add as many bands, to tweak as you would like, and assign them to your desired frequencies.

Here is a 12 band EQ that I slapped together for show and pulled hard on many of the freqs:

That looks like my vocal EQ.
 
Thanks man this is what i was looking for and you were right i was using the parametric...this is a parametric..BTW the bandwidth fader is th "Q" right?
