It’s a frequency modifying processor that changes the tone of whatever you’re processing, and if you’ve ever used bass and treble controls before, these are a simple form of EQ. The other similar and related concept you’ll encounter is a filter, and this also influences the frequencies you hear. For convenience, we generally say that an EQ can both cut and boost the selected frequencies, whereas a filter only removes selected frequencies. That said, you will encounter some EQs that only cut or boost, and you will also find that resonance within filter designs actually results in frequency boosts, so things aren’t quite that simple.
“You can change the tone of your sounds with both EQ and its related filter”
The EQ you have in your DAW is a powerful tool and will typically include a number of bands, each with a boost/cut control, frequency control and sometimes a width (Q) control. If it has all three options it’s called parametric. Even so, not all EQs are the same and this is to do with various shapes or filter types they employ. The most common shapes are low shelving, high shelving and peak. For the shelving design the frequencies above (high shelving) and below (low
