Ciao Guys, Manuel's here from masteryourtrack.com
The equalizer (EQ) is one of the core elements of mixing. I can mix a song with two or three compressors, but please give me at least one EQ for each channel.
EQs mainly help to manage the balance of frequencies of the song. Let's see its main parameters, and then some practical advise.
Type Of Equalizers:
There are three types of equalizers: parametric, semi-parametric and graphic.
The main difference between these EQs is the number of the parameters available.
Parametric: frequency, boost/cut, Q
Semi-parametric: frequency, boost/cut
Graphic: boost/cut (they have fixed frequencies)
Frequency — This is the point in the frequency spectrum at which a filter or EQ is applied.
Boost/Cut — The amount of gain (boost) or reduction (cut) applied at a given frequency.
Q (or bell) — Q stands for “quality factor.” This is the amount of frequencies next to the selected one that will be affected by the boos or the cut.
EQ Practical Advices:
If you find yourself over-EQing an instrument or experiment with an EQ over and over, your ears are probably tired. Take a break.
EQ while listening to the mix, not the instrument in solo.
You can’t EQ frequencies that are not there.
Use a narrow Q when cutting and a broader Q when boosting.
Always match the volume pre/post EQ, so you don’t get fooled by the difference in volume when comparing the processed and non-processed sound.
Don’t boost all the instruments on the same frequencies but try to choose different frequencies to reduce the masking effect.
Use digital EQs to cut and analogue emulations to boost.
