Adam D Posted April 23, 2011 Share Posted April 23, 2011 Hey, this may be one of those really obvious questions, but I'm stuck. I'm used to setting eq in a few different ways. I'm used to using knobs for higs, mids, and lows.... I'm used to notching out rattles and buzzes using a prametric eq or notch filter, and I'm used to using a 31 band eq. But I'm totally in the dark as to how to efficiently and effectively use the equalizer in Logic's channel strip. I'm deep into the MacProVideo training series, and I see them using it, but I still don't really get it. Is there a tutorial that anybody knows of, or a "how to" on this kind of EQ. (what is it anyway? Graphic EQ?) I'm sure I can get it, but clearly I'm missing something at this point. Can anybody point me in the right direction? Thanks, Adam Link to comment Share on other sites More sharing options...
David Nahmani Posted April 23, 2011 Share Posted April 23, 2011 Hi Adam, It's a parametric EQ and it's called "Channel EQ". You can double-click the EQ thumbnail display at the top of a channel strip to insert that plug-in in the first available insert slot. I have a good quick tutorial on that channel EQ in my Mixing lesson in my book (see my signature). Otherwise, start with the manual, it does an excellent job at explaining how all the Logic plug-ins work: Channel EQ If after reading that page while playing with the Channel EQ you still have questions, ask them here and we'll help!

Adam D Posted April 23, 2011 Author Share Posted April 23, 2011 cool. I have your book. I'll check it out. Appreciate it! Adam Link to comment Share on other sites More sharing options...
David Nahmani Posted April 23, 2011 Share Posted April 23, 2011 cool. I have your book. I'll check it out. Appreciate it! Oh great! Then turn to Lesson 9: Mixing, and look for the chapter on Frequencies/EQing, I show how to use the Channel EQ to eq a Snare Drum. Link to comment Share on other sites More sharing options...
Adam D Posted April 23, 2011 Author Share Posted April 23, 2011 I will. I don't have your book with me right now, but I will start carrying it with me I think my biggest problem here is that I have no idea what any of these things are. High pass filters, shelves, bells, Q, etc. Never had to understand it before. With a 31 band, I could just hear what I wanted, cut back the stuff I didn't, bump up the stuff I wanted more of. Obviously this is a better tool, but once again, it's a whole new learning curve. I need a cheat sheet on the basics that precedes the Logic manual. Maybe it's hard to believe, but the terminology they use makes is basically inaccessible to me. I'm thrilled to learn, but I'm coming from the world of fine, antique, acoustic, Italian violins. They come with their own EQ . And the 31 band EQ doesn't require me understanding much of anything, but instead, just use my ears. I'm sure there's somebody out there that can help me get from point A to point B. If you know of a good basic tutorial that can hep me get up to speed on this kind of EQ, I'll read it. Until then, I guess I'll just keep tinkering. Thanks for your help! Adam Link to comment Share on other sites More sharing options...
David Nahmani Posted April 23, 2011 Share Posted April 23, 2011 I see what you mean. I would start by using only the parametric EQ (a.k.a. "Bell Filter"). Forget about the other ones for now. One band of parametric EQ is like having one of your 31 bands of EQ on your graphic 31 band EQ, except now you can also finely adjust its horizontal position (so instead of having to choose between 125 Hz and 250 Hz, now you can slide your EQ band from 125 to 126 to 127 to 128.... to 248 to 249 to 250 Hz. So if you wanted to only boost 187Hz, that's not a problem. The other thing you can finely tune is the width of the EQ band (aka Q or Quality, aka Resonance....). That means you can choose to almost only affect 187 Hz (very narrow EQ band), or affect from 120 to 250, or from 60 to 500... etc... so you're centered on 187 Hz, but you're also affecting all the frequencies around that (wide band). Hope that helps a bit? Easiest to experiment with it while playing a sound (like a vocal recording or a drum loop) through it. Link to comment Share on other sites More sharing options...
beej Posted April 23, 2011 Share Posted April 23, 2011 Learning is a good thing Start with the channel EQ. The other EQ's are basically simple specialised derivatives for a particular purpose - a high pass filter is a filter which let's the high frequencies through (hence "hi pass") - ie, it removes the low frequencies. So you'd use this if you just wanted to lessen some low frequency bass rumble, without having to use a whole multi-band EQ to do it. Some internet searches on EQ will also give you the basic terminology about things like "shelves" and "bell" EQ curves. Link to comment Share on other sites More sharing options...
Adam D Posted April 23, 2011 Author Share Posted April 23, 2011 Oh, yeah, that's really helpful!!! One step back though.... the bell curve buttons at the top?? I don't get it. Amy I choosing to use a type of curve? Then choosing to apply it to a certain frequency? I feel like I'm all thumbs here. Something is still missing.

Pick one of the parametric EQ button and turn it on (blue): buttons 3 through 6 are parameteric EQs. Turn off all other buttons to avoid being distracted or making mistakes for now.

Adam D Posted April 23, 2011 Author Share Posted April 23, 2011 Ok, this is great. One more question, if you have time to answer... So, the flat eq offers 8 parameters to mess with, the middle 4 of which would be equivalent to a 4 band parametric eq, right? And each of those bell eq's can stay low, mid/low, mid/high, and high OR you could take the one that is in the highest position and move it all the way to the left and take the one in the lowest position and move it all the way to the right. (I see that I can do this.) Or I can turn all off but one and just notch out a nasty buzz if I want. But if I find 5 items I want to mess with using the bell's, I'm out of luck, right? As there are only 4 bands. Just for argument's sake. Or if I was some sort of freak who liked to take my 31 band, starting at the bottom and alternating one up, one down, one up, one down, all the way across the 31 bands, I'm also out of luck here, right? I only have 4. I think I'm getting it. So, if I normally, on a 3 know eq, cut my highs a bit, boost my mids a bit, boost my lows a little bit, and then notch out a buzz at 15khz, those knobs probably have pritty wide Q, right? So I'd roll off the highs, put a hump at the mids, then a small hump at the lows, then a very small Q, -30 at 15,000. Am I getting this? I guess I'm coming at this from a live performance perspective. Thanks for all your help. Link to comment Share on other sites More sharing options...
beej Posted April 23, 2011 Share Posted April 23, 2011 You can always insert another EQ plugin and get more bands to tweak... or get a third-party EQ plugin that has more bands... Link to comment Share on other sites More sharing options...

Almost... .30 would be a w-i-d-e Q 100 would be a very narrow Q Low numbers = wide Q (bandwidth affects many frequencies) Higher numbers = narrow Q (tight bandwidth affects very few frequencies--notching) Just try it and you'll see.

widdershins Posted April 24, 2011 Share Posted April 24, 2011 If you prefer to do it the way you used to do it, choose the plugin Audio Units > Apple > AUGraphic EQ. That gives you a 31 band EQ of the sort you're used to. However, it's probably better to learn the Channel EQ - it's a bit more precise. I didn't read the whole thread, so I'm not sure if this has been mentioned, but here's a useful tip for EQing: Take any EQ band, boost it waaay up, and then sweep slowly up and down the frequencies. If you're looking for a particular frequency that needs cutting out, you should be able to find it easily this way, it'll pop out at you like nobody's business. Then simply cut to taste. Repeat for as many notches as you need. Link to comment Share on other sites More sharing options...
