EQ

Well, I'm getting a little closer to where I need to be on the EQ stuff.

I read some in the techniques forum and there was a nice link posted by Chaz, about EQ and whatnot.

When is it better to use a shelf EQ or a peak EQ instead? When should one not use it at all?

One the "Q," does the Q change the freq only vertically(up and down)--like octaves range or width(side to side).

I think I can visualize the shelfs some. It's like taking a layer of bricks on one side of a house not yet built and when you add a shelf EQ to it, it's like pumping up one layer or two layers within all of them, on steroids. :) Weird yes, but I think this works. IT also pumps up all the freq above that area. I read it can change the general tone and also reduce noise?

With a peak shelf or peak EQ I guess, it only does a layer or two and NOT ALL the other stuff below or above.

I assume you can set the shelfs where you want to reduce or boost tone. Can you change size of the shelf by using the Q? I think that's how you do it...

Wish they would show a band of shelf or more the area it affects in the graphical representation--like how wide it is on the freq spectrum. I think it just shows a line.

There were some useful ideas in the article Chaz posted on specific things, which is what I like to read, but nobody has really spelled out the relationships on the presets and bands and shelfs, as much as I would like. Use a preset with a shelf, change the Q? SKip the presets, use a shelf, tweak the Q and a band?

You can use 2 shelfs or peaks at once right? Where would this be recommened above just using the bands or spot treating the EQ?

    Peaks are specific, shelves are general. Think about it this way: If your track has too much bass, put a high pass (or low shelf, its the same thing) filter in and lower the bass. If the track needs a little more air, put a peak filter in around 16 khz or so with about 3-4 db of gain. Spot treating is always better, because it lets the track sit better. Hope this helps.

    The "Q" adjusts the frequency range (width) that is affected by a change in the frequency slider. You can boost a bunch of db's at 10 khz, but how does that affect the surrounding frequencies. With a high Q, the surrounding frequencies are also boosted, with a low - or narrow - Q, only the 10 khz can be boosted. Think of the eq wave form as a gently sloping hill - that's a wide Q. If the eq wave is a spire, that's a narrow Q.
