Filter types include high-pass, low-pass, peak, notch, high-shelf, and low-shelf.In our discussion of the different types of EQ, we briefly mentioned parametric EQ.But there are things about parametric EQ we have yet to go over.
So lets dive deeper into the nuances of this type of EQ, and what makes it a cut above. A refresher on EQ Remember that EQ stands for equalization, which refers to the manipulation and balancing of audio frequencies within and between electronic signals. ![]() When we discuss a particular note, however, were actually referring to the fundamental frequency of that note. Still, other frequencies will rear their heads in any given recording. This is due to resonance, or the resultant frequencies reflected by other objects due to the initial vibration. The old trope involving the finger circling the wine glass demonstrates resonance. This all gets into complex physics jargon, so we wont go much further than that. To keep things simple, any track in your mix will contain multiple frequencies, some more present than others. The core of the bass guitar, for instance, a low-end instrument, can be found mostly between 60 Hz and 250 Hz. This isnt to say, however, that the bass wont resonate at other frequencies. In fact, some powerful bass overtones can be found as high as 1k Hz. Likewise, different aspects of a crash cymbal, snare, or tom can be emphasized depending on which frequencies are boosted or cut. All this means is that any instrument you record can be placed all over the frequency spectrum. But only certain frequencies will allow that instrument to really shine and reach its full potential, so to speak. Additionally, every mix must juggle several tracks and instruments at once. Frequencies will naturally collide, cancel, and overwhelm the ear if left alone. The best sounding vocal track might sound dull given the rest of the mix. What is parametric EQ Of the several types of EQ, parametric EQ sounds like the most complicated. After all, every type of EQ deals with distinct measurements of frequencies. However, parametric EQ has distinct advantages, namely four variables: frequency, type of filter, Q factor, and gain. Frequency refers to the specific frequency you wish to focus on.
