Was searching around on DOA and found a good Thread on EQ'ing. So I cut out the bull Shit and kept the good stuff so enjoy. It's all good stuff and really right on.

I did not document who posted what so thanks to all who contributed.


20 Hz and below - impossible to detect, remove as it only adds unnecessary energy to the total sound, thereby most probably holding down the overall volume of the track
60 Hz and below - sub bass (feel only)
80(-100) Hz - feel AND hear bass
100-120 Hz - the "club sound system punch" resides here
200 Hz and below - bottom
250 Hz - notch filter here can add thump to a kick drum
150-400 Hz - boxiness
200 Hz-1.5 KHz - punch, fatness, impact
800 Hz-4 KHz - edge, clarity, harshness, defines timbre
4500 Hz - exteremly tiring to the ears, add a slight notch here
5-7 KHz - de-essing is done here
4-9 KHz - brightness, presence, definition, sibilance, high frequency distortion
6-15 KHz - air and presence
9-15 KHz - adding will give sparkle, shimmer, bring out details - cutting will smooth out harshness and darken the mix


60Hz with a Q of 1.4 -- Add fullness to kicks.
100Hz with a Q of 1.0 -- Add fullness to snare
200Hz - 250Hz with a Q of 1.4 -- Adds wood to snares
3Khz with a Q of 1.4 -- Adds atack to snare.
5Khz with a Q of 2.8 -- Adds attack to Kicks
7Khz with a Q of 2.8 -- Adds Sharpness to snares and percussion
10Khz with a Q of 1.0 -- Adds brightness to hats and cymbals


ok kick drums i usually cut the bass below 90 to keep the phatness w/o conflicting with the bass
I usually notch somewhere around 250 which seems to clear up a bit of muddiness
cut all sounds below 20hz as they also mud up the mix

kick drums which I cut below 75Hz

for your vynil masters make a harsh cut at 12khz or preferably de esser in that region.(this applies to mastering tasks for vynil only)
for cd masters, that gives the desired air on top......

what can be said abt the 4500hz region is, this is the main content of any human vocals.so if noone understands your voice sample and you want it to be understood,boost it.....


to find the sweet spot of a sound...

solo it..

make the q as small as it will go and boost the eq 6dB and sweep the frequency untill you really hear the sound come out (usually on the attack)...

then reduce the amount of q and gain....

this also works if there is something you want to get rid of in a sound.. find that sound by using this same method and reduce the gain...

if you want to add OMMF to the kick or snare..

tune an oscilator to the same pitch as the kick or white noise to the snare...

and KEY it with the Kidk or the Snare and it will add that ommf your lookin for..

heard alot in hip hop on the kicks and in the 80's on the snare..

another way of doing it if you dont know how to key an oscilator... is just get a sample and have it play at the same time as the kick or the snare.. the keying just does that for you. hehe

Something that often gets over-looked is COMPARING to the original. Whenever you re-EQ someting you NEED to be able to cut everything you've just done and compare it to the original sound. Theres no use doing it if you can't look back on how it was to see why you EQ'd it in the first place.

Basically make sure whatever you use to EQ has some form of bypass so you can flip between before-after. If you have something that will take 'snapshots' then thats even better as you can listen to a few different versions of EQ setting to see which fits best.

probably one of the most important things to remember with eq if you ask any engineer; i haven't seen anyone mention it, so i will.

when it comes to eq, try as hard as possible to use a cut rather than a boost. this will give you more room to work with. one of the most common uses for eq is to resolve conflicting instruments. rather than boosting the one that you want to stand out, try cutting the frequency in the instrument that doesn't quite require it.

but i normally cut off kicks at 80-100 (with a not-too gentle roll off) and take a big piece out at 300ish. i also usually boost snares aroung 150-200 and 1000-1500. 150-200 is where the meat of the snare is, and 1000-1500 is where the snap is.

Boost or Cut? Or both in combination?

I just recently read an article that recommended EQing sounds in the mix (not solo) and then finding the most prominent frequency range (by sweeping a heavily boosted paramteric EQ) and boost that just as much as needed to bring out the target sound in the mix, not more.

Then use a heavily cut parametric EQ and sweep below the frequency you just boosted, to see if you can find a frequency range that is good to cut in order to bring the target sound out in the mix even further.

I find I often use cutting frequencies to remove irritating ringings, rumble, noise etc but I don't think I've thought about it in terms of actually listening if it brings out the sound more in the mix by subtracting some of the frequencies of said sound.


on some sounds where it seems too sharp & hurts your ears, lower/notch it at around 3KHz

i definately think that its best to start by cutting frequencies rather than boosting as this gives you a lot more room to play! you can allways boost things a bit more later if you need more OOMPH in that freq range!

I find myself often having to boost the midrange in my drums lately, last night I did a track and had to put a +3 dB EQ in the 800-3000 Hz range on the final mix (obviously not the most optimal choice but I'll fix it in the sequencer later with specific channel EQing and so on).

EQ Reference: Frequencies


50Hz
Boost: To thicken up bass drums and sub-bass parts.
Cut: Below this frequency on all vocal tracks. This should reduce the effect of any microphone 'pops'.

70-100Hz
Boost: For bass lines and bass drums.
Cut: For vocals.
General: Be wary of boosting the bass of too many tracks. Low frequency sounds are particularly vulnerable to phase cancellation between sounds of similar frequency. This can result in a net 'cut of the bass frequencies.

200-400Hz
Boost: To add warmth to vocals or to thicken a guitar sound.
Cut: To bring more clarity to vocals or to thin cymbals and higher frequency percussion.
Boost or Cut: to control the 'woody' sound of a snare.

400-800Hz
Boost: To add warmth to toms.
Boost or Cut: To control bass clarity, or to thicken or thin guitar sounds.
General: In can be worthwhile applying cut to some of the instruments in the mix to bring more clarity to the bass within the overall mix.

800Hz-1KHz
Boost: To thicken vocal tracks. At 1 KHz apply boost to add a knock to a bass drum.

1-3KHz
Boost: To make a piano more aggressive. Applying boost between 1KHz and 5KHz will also make guitars and basslines more cutting.
Cut: Apply cut between 2 KHz and 3KHz to smooth a harsh sounding vocal part.
General: This frequency range is often used to make instruments stand out in a mix.

3-6KHz
Boost: For a more 'plucked' sounding bass part. Apply boost at around 6KHz to add some definition to vocal parts and distorted guitars.
Cut: Apply cut at about 3KHz to remove the hard edge of piercing vocals. Apply cut between 5KHZ and 6KHz to dull down some parts in a mix.

6-10KHz
Boost: To sweeten vocals. The higher the frequency you boost the more 'airy/breathy' the result will be. Also boost to add definition to the sound of acoustic guitars or to add edge to synth sounds or strings or to enhance the sound of a variety of percussion sounds. For example boost this range to:

Bring out cymbals.
Add ring to a snare.
Add edge to a bass drum.

10-16KHz
Boost: To make vocals more 'airy' or for crisp cymbals and percussion. Also boost this frequency to add sparkle to pads, but only if the frequency is present in the original sound, otherwise you will just be adding hiss to the recording.




Specific Instruments


Vocals

General:
Roll off below 60Hz using a High Pass Filter. This range is unlikely to contain anything useful, so you may as well reduce the noise the track contributes to the mix.

Treat Harsh Vocals:
To soften vocals apply cut in a narrow bandwidth somewhere in the 2.5KHz to 4KHz range.

Get An Open Sound:
Apply a gentle boost above 6KHz using a shelving filter.

Get Brightness, Not Harshness:
Apply a gentle boost using a wide-band Bandpass Filter above 6KHz. Use the Sweep control to sweep the frequencies to get it right.

Get Smoothness:
Apply some cut in a narrow band in the 1KHz to 2KHz range.

Bring Out The Bass:
Apply some boost in a reasonably narrow band somewhere in the 200Hz to 600Hz range.

Radio Vocal Effect:
Apply some cut at the High Frequencies, lots of boost about 1.5KHz and lots of cut below 700Hz.

Telephone Effect:
Apply lots of compression pre EQ, and a little analogue distortion by turning up the input gain. Apply some cut at the High Frequencies, lots of boost about 1.5KHz and lots of cut below 700Hz.


Hi-Hats

Get Definition:
Roll off everything below 600Hz using a High Pass Filter.

Get Sizzle:
Apply boost at 10KHz using a Band Pass Filter. Adjust the bandwidth to get the sound right.

Treat Clangy Hats:
Apply some cut between 1KHz and 4KHz.


Bass Drum

General:
Apply a little cut at 300Hz and some boost between 40Hz and 80Hz.

Control The Attack:
Apply boost or cut around 4KHz to 6KHz.

Treat Muddiness:
Apply cut somewhere in the 100Hz to 500Hz range.


Guitar

Treat Unclear Vocals:
Apply some cut to the guitar between 1KHz and 5KHz to bring the vocals to the front of the mix.

General:
Apply a little boost between 100Hz and 250Hz and again between 10KHz and 12KHz.


Acoustic Guitar

Add Sparkle:
Try some gentle boost at 10KHz using a Band Pass Filter with a medium bandwidth.

General:
Try applying some mid-range cut to the rhythm section to make vocals and other instruments more clearly heard.

kick>> bottom depth at 60 - 80 Hz, slap attack at 2.5Hz

snare>> fatness at 240HZ, crispness at 5 KHz

hi hats/cymbals>> clank or gong sound at 200 Hz, shimmer at 7.5 kHz - 12 kHz

rack toms>> fullness at 240 Hz, attack at 5 kHz

floor toms>> fullness at 80 - 120 Hz, attack at 5 kHz

horns>> fullness at 120 - 240 Hz, shrill at 5 - 7.5 kHz

strings>> fullness at 240 Hz, scratchiness at 7.5 - 10 kHz

conga/bongo>> resonance at 200 - 240 Hz, slap at 5 kHz

vocals>> fullness at 120 Hz, boominess at 200 - 240 Hz, presence at 5 kHz, sibilance at 7.5 - 10 kHz

When mixing bassline and kick drum, give the kick some extra dBs at 90-something Hz (listen to the sound and find where it has it's punch) and remove a few dB from the bassline sound at this same frequency. Then go to around 400 Hz on the kick drum (where it's boxiness resides) and remove a few dB, this will make it feel more punchy and thumpy, in a nice way (at least it has worked well for me in the sound I am trying to achieve). Finally add a few dB to the bassline at this same 400-something frequency, this will increase the presence and audibility of the bassline when played at the same time as the kick.

Good point - those frequency tips are taken from many different sources and I think I've learned more over the time now so I wouldn't say that particular tip is really something to rely on. I more often cut at around 400 Hz, add at around 100 Hz, notch at 250 Hz and also I always cut my kicks at 70-80 Hz. Though sometimes I also layer sub hits underneath

just to add to the bass-kick debate, for those using fm kicks ala; teebee, dom n roland. I found that cutting 16-30hz and boost at 250hz worked a treat. But im increasingly comming to the conclusion that there really is no one size fits all rule when it comes to kicks, apart from getting rid of the lower end of the bass spectrum to make way for any basslines in your tunes

I have seen this on doa as well. good job trimming it down. it is more understandable.

thanks lost...
