General EQing reference

useful thread about EQing on idmforums.com

http://www.idmforums.com/showthread.php?t=11466

General:
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

loads more detail about EQing kicks/vocals/guitars etc on the actual thread

Tried boosting it on a track, fuck it's so correct, added a notch and everything sounded a lot more pleasant.

not a surprise... that freq is the freq of speaking. We're so sensitive for that freq cause we hear it everyday. that's why you dont need to boost it that much. Our ears already boost it naturally. Also a reason why you dont need to boost claps/snaps that much

I'v never used this knowingly, but I find myself always cutting a little bit at 5000 Hz and also at 500 Hz.

PM Daft tnuc for it to be added to the Forum Production Bible!

Good work!

Well done for bringing that over here, idmforums is a wicked place with some great knowledge stowed away between it's boards.

If someone is speaking at 4.5k then they obviously took a very hard kick in the nuts.

Average male voice audio spectrum power peaks near 500 Hz. Average male voice power is 10dB lower at 130 Hz and 1800 Hz than at 500 Hz. It is typically 20dB lower than peak at 65 Hz and 5000 Hz. Average female voice audio spectrum power peaks near 700 Hz. Average female voice power is 10dB lower at 300 Hz and 2500 Hz than at 700 Hz. It is typically 20dB lower than peak at 140 Hz and 5200 Hz.

In the minge then, whatever

4.5k is the (or, an) area for sibilance, not true speech

Very handy!

Thanks very much

The ear is very sensitive there (see fletcher munson) for intelligibility, but it's not where the main energy is transmitted in speech (see above quote)

I *think* (I read once) it's related to danger/detection response, something like that.

you might be interested to know that the ear is most sensitive to around 1k-2k, because thats the fundamental of baby's screaming (evolution - protect the young).

edit - obv a theory, not provable - but true.

paradigm_x · Post by **paradigm_x** » Mon Mar 23, 2009 5:12 pm

oh and speech frequencies are around 500-2k depending on age and sex.

what about Barry White? 100hz business there, surely?

Yes...
Something to do with babies crying too maybe, ie: they're always loud and annoying, but without that correlation back in the day when we was wild, the lions would've gotten rather fat from eating said babies.
