What is an Equalizer?
An equalizer will usually range from the frequencies of 20 Hz all the way up to 20 kHz. This tool can help shape your overall tone and feel of a mix, so it’s crucial to have some familiarity with it.
Different types of EQ
For today, we'll discuss parametric and shelving.
A parametric EQ is very versatile at containing adjustable frequency bands. You are able to pinpoint specific frequencies with different bandwidths and control the levels of those specific frequencies.
These tools will also contain something called a “Q,” which allows you to adjust the bandwidth and select how wide to cut or boost that frequency.
If you are setting the Q to a higher value, it will be affecting a narrow range of frequencies and vice versa.
Another adjustment you’ll be able to make is the gain. The gain will control how much to cut or boost your selected frequency.
Lastly, these EQ’s will contain different filter types. Using this function will allow you to select the shape of the filter you’d like to use.
Some standard filter types will consist of the following:
- low pass filters
- high pass filters
- notch filters
The parametric EQ will be something you use more often than not and will be a go-to when shaping sounds and cutting harsh frequencies.
Most shelving EQ’s will contain high, low and mid bell curve filters. This is great for deepening a mix!
Different Types of Filters
Low Pass Filter
Sometimes you will come across some frequencies that make your eyes ring in the higher side of the spectrum. This is a great tool to use to take care of that and cut them out of the sound.
High Pass Filter
This is the filter you’ll want to play with when your kick and bass are interfering with one another.
Often times this is a great filter to use to clean up any clutter in a mix, as many frequencies are tricky in the low-end and mid-range.
In order to find that harsh frequency, set the Q and gain to a high level and then continue to change the frequency in order to find what you’re hearing.
Moving this up and down the spectrum will help you pinpoint the sound you’re hearing and once you’ve found it, you can bring down the gain until it is gone!
Also, if you automate the notch filter, you can create some interesting shaping effects.
