Eq

[SouthSIDE Glen]

More precisely, Q is 1/octave. So a Q of 1 covers a range of an octave, 2 is a half octave, etc.

Even more precisely, Q usually defines the width of the bell curve surrounding the center peak which has a boost (or cut) value of less than 3dB down from the peak. The actual total bandwidth affected can be as much as two to three times that defined by the Q number.

thanks for the Q breakdown fellas, i think that may be a real turning point with this EQ thing..........

off to the digital-board we go........................


edit: holy hot-rocks batman, we have improvement............. once i have it done, i'mma post an mp3 and wav comparison from my most recent mixing of the song i'm workin on, to the one i'm currently doing, maybe ya'll can give me more pointers and things to look out for after i actually post the audio!

I just printed up that chart,I think I need to go buy ink now.
I need the chart because I've always just EQ'ed by ear(poorly)without ever knowing what frequency it was.This may help clear up the big picture.

yeah it helped me alot, i can't identify the exact frequencies, but now i can tell which range (meaning low, mid, high) the frequency lies in off my ears alone without visual aid and it also helped me understand what altering the dB's in each range does.......

it helped me out big time, i haven't perfected my mix-game just yet, but i'm way better off than b4, and each time i mix something it sounds better and better, just not fully comfortable in my approach, but that probably comes from being too much of a perfectionist on my part..............

Hey Glen, I noticed on the chart the color codes for fundamental frequencies and harmonics (red and yellow) show the harmonics starting way above where I thought they should actually start. Any reason behind that or am I just losing it?

Anyone here EQ the overtones?

keep in mind that boosting EQ adds phase shift to the track. Try to cut instead of boost to make something fit better in the mix.

Actually both boosting and cut can add phase shifts. This depends on the design of the EQ/Filters not whether you're boosting or cutting. If you don't want phase shift, use linear phase EQs. However, phase shift isn't always a bad thing, some of the revered EQs "suffer" from it as well, they just do it in a musical manner.

Star, if I understand your Q correctly, what you're seeing - or maybe more properly, NOT seeing - is the fact that fundamental ranges and harmonic ranges can have a great deal of overlap.

For example, the first overtone of 400Hz is 800Hz. However, 800Hz is also a fundamental all it's own within the main range of most instruments. In that regard, you're right; harmonics start way below the yellow (as low as twice the frequency of the instrument's lowest fundamental.)

The chart is designed to show the fundamental range of the instrument, and then include the extended range provided by main harmonics in an effort to show an estimated frequency range for the main energy of an instrument.

Just because the yellow starts at 1kHz (say) doesn't mean there are not harmonics below that, it simply means that's approximately where the fundamentals end.

That's kinda what I thought. Maybe a footnote to explain that in the chart would help.

I admit I never considered it might be interpreted that way, you bring up a good point. Let me consider a few options there...

Cutting adds phase shift as well. Eqs add phase shift whether they are cutting or boosting.

Problems that arise from boosting include extra noise, since noise gets boosted along with signal, and maybe some ringing or increased resonance at extreme boost levels.

Phase shift, however, is not a reason to cut instead of boost. It's a myth.

ahh this is where some of the tools in the Waves Transformer bundle comes into play.......
