After running EmoQ you can view the results, in what is a three column layout - Range/frequency, gain/DB and Q. What is that Q?
If I manually adjust the db gain, should i also change the Q?
I haven't been able to find a reference guide or any mention of what tweaking the Q setting might do. Any insight is greatly appreciated.

Here's a thorough discussion, the second section "Audio and Music", starting with the second paragraph. A simple explanation is that it determines how specific the equalizer is in the range of frequencies it controls - the higher the Q the fewer the frequencies that are affected around the center point, the lower the Q the more frequencies that are affected. That is unless you're a Star Trek TNG fan, then it's a whole 'nother thing.  en.wikipedia.org/wiki/Equalization |

Best explanation ever. Thank you.

Think of it as the inverse of the damping factor. Low Q means a high level of damping, while high Q means low damping and longer resonance. Q of .5 is "critical damping", which lets the resonance decay back to equilibrium quickly but not continue much past it. So a door that can swing most of the way shut and then eases into place without slamming is critically damped. If you bounce a corner of your car up and down and let go, it should stop in about one additional stroke, and I'd guess its Q factor is a bit below .5 (but not too much so or your whole car would bounce down the road like you had no springs). en.wikipedia.org/wiki/Q_factor |
