With which I can make the bass explode the room?

As we have seen in the previous instances of this series, EQs are a pretty flexible tool when It comes to shaping a sound and highlighting Its better points while cutting Its worst in a determined frequency range. What we'll present now, as a finisher to the trilogy, is the most common types of equalizers that you can find in a mixing or working space that deals with this tedious though beautiful discipline. Some of these are:

Parametric EQ:

These are usually the most common due to different points. The first of which being their flexibility, being able to shape and change the frequency in which Its bands operate, all in a graphical interface. Parameters included in these are the Q, which controls the narrowness or wideness in the frequency space that the cut will embark; the gain, which will be how much of that specific frequency will be cut or boosted, filter types (Like the ones mentioned in the part 1) and the filter slope, which will control how steep (Abrupt) the cut with the filters will be. No matter how pretty they look, remember to use your ears when EQing with these.

Semi-Parametric EQ:

Basically, a more bare-boned version of the Parametric EQ, where a couple of features are missing. They don't have a graphic interface in which to guide us, so we'll have to rely on our ears. Also, they're not so flexible, with fewer bands, each one fixed in denominations of the frequency space listed (Example: Low-Mid-Hi).

Dynamic EQ:

This kind of EQ mixes the properties of a Compressor/Limiter with the ones proper to Equalizers. Being able to use the sidechaining process (Altering one audio signal with the other, topic which we'll discuss in a later article) to boost or cut certain frequencies of the listed audio track using another audio track as a trigger. It also features the graphical interface of a parametric EQ and Is as flexible as the latter when It comes to the control of the bands, slopes and resonance.

There are even more variations to EQs, as there are Graphical EQs and shelving EQs, though they share the same fundamentals as the ones mentioned here, being these the most common.

As we conclude, We expect that this little set of pieces of information can be helpful to you and your endeavors as someone who's interested in the world of mixing and music in general, being able to consider more options and seeing, even if It is only in the surface, how important of a tool the EQs are for a producer/beat maker/engineer.
