EQ in mixing is a technique that is used to cut out or boost certain frequencies in audio. EQ will not apply everytime and in every case because every project differs and you don’t always have to apply EQ to elements of your music. Some sounds don’t require EQ, especially processed sounds.
Therefore choosing to use EQ should be to improve a sound, but if the sound is okay than you don’t need to use any EQ.
This post will walk you through various frequencies so you can have a basic idea of how you could use EQ and when EQ isn’t necessary.
These are particularly low frequencies and they are basically the ones that are cut or boosted to either trim down or enhance the low end.
You’ll find most bass instruments like kicks, drums and Tom’s at this frequency range.
Therefore you have the option of cutting the low end or boosting it to make the sound fit well into your mix,
in a situation where you find nothing wrong with your bass instrument then theres no need to use any EQ on it.
This is still pretty much the low end of the mix and will be used to either improve bassy sounds and adding fullness to instruments like snares and guitars.
The 200Hz frequency range is most associated with muddiness especially I’m live performance situations.
Therefore whenever your mix exhibits muddiness, you can simply use an EQ to reduce this frequency range here.
300 – 600 HZ
When you cut these frequencies on your kicks, it will be much sharper, plus it will reduce its boxiness and give it more thickness.
For basslines, boosting these frequencies here will improve their clarity.
700 – 800Hz
This frequency range here can help you bring out the bass more without messing up the low end.
Boosting this range of frequencies;
allows you to access upper harmonics to make them alot more audible within the mix.
Reducing this frequency range will help you get rid of the cheap sound of an acoustic guitar.
1 – 4Khz
This frequency range is used to improve the presence of a sound,
for example a bass guitar boosted at this range (around 1.4 – 1.5 Khz) will help you bring out the string sound.
For vocals cutting the 1.5Khz frequencies will reduce the nasal sound.
Around 3Khz is where you boost if you’re looking for punch and a lot of presence.
This frequency range adds extra presence to vocals plus it will give instruments like Tom’s a lot more attack.
Cutting the 5Khz will make things sound a lot more distant.
7 – 10Khz
Boosting the 7Khz frequency range can help liven up dull vocals, the 6 -8 frequency can also be reduced to get rid of sibilance.
Everything above 10Khz gives everything a high sheen and air to sounds.
