EQ - is adjusting the volume of a frequency
Types:
- shelving EQ
- graphic EQ
- parametric EQ
- semiparametric EQ
One of the most used EQ is Parametric EQ
- Parametric EQ is build up with 8 bands :
1.Low Cut Filter (or High Pass Filter)
2.Low Shelf Filter
3.Bell Filter 1
4.Bell Filter 2
5.Bell Filter 3
6.Bell Filter 4
7.High Shelf Filter
8.High Cut Filter (or Low Pass Filter)

This 8 bands can be controlled with 3 parameters:
- frequency - let as choose the frequency we want to adjust
- volume/gain db - let us adjust the amplitude of the frequency
- Q ( a low Q setting as 0.75 a large range of frequencies is affected, a high Q setting – such as 21.0 results in a narrow bandwidth and a smaller range of
frequencies affected)
