What is a shelving EQ?
Shelving EQ. A shelving EQ attenuates or boosts frequencies above or below a specified cutoff point. Shelving equalizers come in two different varieties: high-pass and low-pass. Low-pass shelving filters pass all frequencies below a specified cutoff frequency, while attenuating all the frequencies above the cutoff.
What is filtering in Eq?
The process of filtering is very self-explanatory. Where an EQ can adjust many different parameters at once, filters tend to control just one. Filters essentially do what they say – they filter out, or remove certain frequencies. There are four main types of filters: Low pass, High pass, bandpass, and band-reject.

What is the difference between a filter and an EQ?
The main difference between filters and equalizers are that filters only attenuate (i.e. reduce) certain frequencies in the spectrum, whereas equalizers can either boost or attenuate the strength of particular frequency bands of the spectrum.
What do filters on an EQ do?
Filters and Equalizers (EQ) A filter is a device that attenuates or removes a user-defined range of frequencies from an audio waveform while passing other frequencies. Typical filters are low pass, high pass, and band pass.
What does shelving mean in EQ?
In a shelving EQ, a band of frequencies is boosted or cut either in the high-frequency end of the spectrum or in the low-frequency end. 'Shelving' is not a term that is ever applied to a mid-range boost or cut. So in a shelving EQ, all frequencies are boosted or cut by the same amount.
What is the difference between a high low pass filters and shelving curves?
Low Shelf Vs. High Shelf Filters. The major difference between low and high shelf filters is the name: low shelf filters affect (boost or cut) frequencies at the low-end of the audio signal while high shelf filters affect (boost or cut) frequencies at the high-end of the audio signal.
What does a filter do in audio?
What is an audio filter? The audio filters are the electronic circuits designed to amplify or attenuate a certain range of frequency components. This helps eliminate the unwanted noise from the audio signal and improves the tone of the output audio.
What's parametric EQ?
A parametric equalizer lets you control three aspects: level (boosting or cutting decibels), the exact frequency, and the bandwidth or range (also known as Q or quotient of change) of each frequency. As such, parametric equalizers offer surgical precision when it comes to affecting the overall sound.
What does a high shelf filter do?
A high shelf filter attenuates or boosts frequencies above a specified frequency point. High shelf filters don't cut frequencies out completely like high cut filters. Instead, they gradually reduce or boost treble frequencies.

What does low shelf mean EQ?
Eamon. October 22, 2021 06:00. Descript's Low Shelf EQ (equalizer) lets you boost or cut low-end frequencies in your audio. The Low Shelf EQ provides a simple way to quickly shape your sound - tame a boomy voice by cutting the low frequencies, or add some low-end power with a low shelf boost.
What are two main types of equalizers and what are the differences between them?
Parametric EQs often allow you to switch the high and low EQ bands between shelving and bell shapes. Shelf EQs boost or cut a signal above or below the specified frequency, while bell curves boost or cut the signal centered around the selected frequency.
What type of EQ is FabFilter?
FabFilter Pro-Q 3 is a top-quality EQ plug-in with perfect analog modeling, dynamic EQ, linear phase processing, and a gorgeous interface with unrivalled ease of use.
Are higher order filters better?
High-order filters are used because they have the ability to roll off gain after the bandwidth at a sharper rate than low-order filters. The attenuation of a filter above the bandwidth grows proportionally to the number of poles. When rapid attenuation is required, higher-order filters are often employed.
What does a high pass EQ filter do?
A high pass filter is a simple, effective type of EQ curve, one that scoops out unwanted low frequencies from any audio source. They are fantastic when used correctly to clean up woofy signals and tighten up arrangements. When used incorrectly, they can cause more problems than they solve.
What are filter plugins used for?
Filter plugins are simple because they serve a straightforward purpose – they remove some frequencies while letting others pass through. But, filter plugins are also incredibly powerful because they can be used for many purposes, like creative sound design, building tension, and smoothing out transitions in a song.
What is the best setting for EQ?
From our testing, we recommend you target 125 Hz for adult male speakers, 200 Hz for adult females, and between 250 Hz to 400 Hz for children of any gender.
What EQ settings should I use?
The best equalizer setting for your car is one that is neutral. A neutral setting is best for most genres of music and podcasts. However, if you prefer bass-heavy music like hip-hop or EDM, you could boost the mids and highs by +2 or +4 and boost the bass by +4.
Why use a shelving filter?
The benefits of using a shelving filter: Shelving filters make it really easy to achieve the tone that you’re looking for. If you want things to sound brighter, you boost with a high shelf. If you want things to sound less bass heavy, you attenuate with a low shelf. They’re a great way to make broad overall changes to the sound of a signal.
What is a High-shelf?
A high-shelf is used to create a boost or attenuation in the frequency spectrum’s high end.
What is a shelf filter?
A shelving filter which boosts or attenuates the high end of the frequency spectrum is known as a ‘high shelf’ . Whereas a shelving filter which boosts or attenuates the low end of the frequency spectrum is known as a ‘low shelf’. In this article, I’ll break down what each of these filters do, how they are controlled, and the benefits of using them.
What are the controls on a shelving filter?
Shelving filters have three main controls. They are the filter’s gain setting, its frequency setting, and the steepness of its slope. Let’s look at each control in more detail…
What happens to gain change in low shelf?
As with the low shelf, there is a transition band over which the filter applies the gain change. Once the full amount of gain is reached, the gain change remains constant all the way to the top of the frequency spectrum.
What is frequency setting?
The frequency setting defines the point at which frequencies above (high shelf) or frequencies below (low shelf) are cut or boosted.
What is the purpose of controlling the slope of a filter?
Controlling the filter’s slope allows you to control the size of the transition band over which the gain change is applied.
What is EQ in music?
In conventional terms, 'EQ' refers to tonal equalisation and involves modest cuts or boosts of amplitude across the frequency spectrum to technically or subject ively 'improve' the signal's frequency response. Equalisation generally consists of filter stages that exhibit shelf or bell-shaped slopes, normally of 6dB per octave and rarely exceeding 12dB per octave. Simple EQ is provided with just a cut/boost control for each frequency band. More complex designs go on to offer adjustable turnover frequencies and possibly some adjustment of Q or bandwidth as well. The most flexible form of EQ is parametric EQ, which provides frequency, bandwidth and cut/boost controls.
What is a minimal phase filter?
Most analogue audio equalisers and filters are 'minimum phase' designs — the well known Butterworth filter designs, for example — where some frequencies experience a different amount of 'processing' delay to others. The steeper the filter, the worse the phase-response variations become, which inherently distorts the waveform shape.
What is passive equaliser?
Passive equalisers place the equalisation circuits either before or after a fixed-gain amplifier — in which case the amp makes up for the inherent loss in the EQ circuit, effectively boosting the frequency range (s) that haven't been cut. Active equalisers incorporate the EQ circuitry in the feedback loop around the amp, which makes its gain frequency-dependent. This is the more common approach in modern EQ designs, but is often claimed to sound inferior.
What is phase shift in EQ?
Every filter and EQ has a phase response which varies in some way relative to the frequency, just as the amplitude response may vary relative to frequency. The process of filtering inherently imposes a small delay, and this is what creates the phase shift.
What is filter EQ?
Filters are generally described as cut-only devices that are intended to remove some portion of the frequency spectrum. They come in three flavours: high-pass, low-pass and band-pass.
Is linear phase a digital domain?
Linear-phase filters are difficult to create in the analogue domain (the Bessel filter is the closest, but cannot have a steep slope between the pass and stop bands), but are fairly straightforward to achieve in the digital domain.

What is the most common type of EQ?
2. Parametric E Q. A Parametric EQ is the most common type of EQ you will come across when mixing in the box. Your DAW will usually come with an EQ plugin as standard and may also utilize an analyzer which displays the frequencies present in the track.
What does a higher Q mean?
A higher Q will affect fewer surrounding frequencies (i.e. is narrow) whereas a lower Q will affect more and is wider. So for example, removing 100Hz with a high Q may affect a range of 80-120Hz, whereas a lower Q could result in 50-150Hz being removed.
What is frequency function on parametric EQ?
The frequency function on a Parametric EQ allows you to select which frequency you are affecting in the spectrum.
What is shelving EQ?
A shelving EQ is actually quite similar to a HPF/LPF. The term ‘shelf’ comes from the way in which the EQ parameters look.
How does a graphic EQ work?
A graphic EQ works by separating individual frequencies into banks of sliders which you can add or remove as needed. The more frequencies contained on a graphic EQ the more accurate the controls are. It’s not uncommon to see graphic EQ’s on older HiFi systems.
What is an EQ?
Simply put an EQ (or ‘Equalizer’) is designed to add or remove certain frequencies in the sound spectrum.
How many faders are in a graphic EQ?
Usually, a graphic EQ will contain between 7 and 31 faders, with each one representing certain frequency ranges. These types of EQ are great for removing problem frequencies that you may find in a mix, so it’s no surprise that they are often used in live sound engineering when ‘ringing out’ a room. As you can imagine, for a live sound engineer on ...
What Types Of Equalizers Are There?
Equalizers can take various forms, but most commonly nowadays, you’ll be familiar with them in parametric form, usually as a DAW plugin. Within a parametric EQ, there are 2 controls for changing the frequency.
Why use high pass filters?
High Pass filters are very common in live sound, and are used to cut out the low frequencies on numerous channels in a mix, as to protect from low end rumble and feedback. Chris Milnes.
Why are shelf filters out of the options?
If the aim is to boost, then automatically the pass filters are out of the options because they don’t do boosts but only cuts.
Why use a shelf filter over a bell?
They are the suitable tools for sculpting a better sound in those corners often more than a bell or pass filters. This is because of the even amount of boost or cut they make across all frequencies. Of course, the decision of whether to use a shelf filter over a bell or pass filter will be determined first by whether you are making a boost or a cut. If the aim is to boost, then automatically the pass filters are out of the options because they don’t do boosts but only cuts. This leaves you with the bell and the shelves.
What are the filters used in EQ?
There are various types of filters used in equalizing, but the commonly used ones are the bell, high pass filter (low cut), low pass filter (high cut), high shelf and low shelf. There are others like the band stop (notch), band pass, and tilt type filters, which are seldomly used except for peculiar purposes.The image below shows the various EQ filter types and their icons. The shelves’ icons look like a sideways laying two pronged fork. The prong-like ends signify they can be used for cuts and boosts. The directions they face denote the end of the spectrum they are to be used on. The left facing icon stands for low shelves, while the right facing one represents the high shelves.
What is an EQ shelf?
EQ shelves are filters like the high and low pass filters. There are 2 types of shelves – the high shelf and low shelf. High shelf can be applied to the trembly high end of sound frequency, while low shelf to the bass bottoms. Like the pass filters, shelves can be used for cuts, but not as drastic. Unlike the pass filters, high ...
What are the different types of shelf filters?
Altogether, we have a total of four possible shelf filter types. These are ; low shelf cut, low shelf boost, high shelf cut, and high shelf boost.
What is low shelf boost?
Low shelf is good for cuts and boosts on bass, solo acoustic guitar, strings, piano, and anything that needs more low end taming or power. High shelf boosts can be used to add crispness to hats, cymbals, shakes and vocals. Knowing how to professionally use EQ in music mixing is the first step to producing radio ready songs in your home studio.
What is a shelf filter?
Unlike the pass filters, rather than totally cutting off the sounds at the set frequency, the shelf filters attenuate the sounds that fall behind the set point by the same amount of volume.
What is a shelving EQ?
A shelving EQ attenuates or boosts frequencies above or below a specified cutoff point. Shelving equalizers come in two different varieties: high-pass and low-pass. Low-pass shelving filters pass all frequencies below a specified cutoff frequency, while attenuating all the frequencies above the cutoff. A high-pass filter does the opposite, passing all frequencies above the specified cutoff frequency while attenuating everything below. Usually, the frequencies beyond the cutoff are rolled off, following a predetermined curve, not cut off sharply, as with a “brickwall” filter.
What is high pass filter?
A high-pass filter does the opposite, passing all frequencies above the specified cutoff frequency while attenuating everything below. Usually, the frequencies beyond the cutoff are rolled off, following a predetermined curve, not cut off sharply, as with a “brickwall” filter.
What is a multiband parametric EQ?
Some multiband parametric EQs offer low and high bands that can be switched to shelving filters. In others, such as the EQ in the Studio Channel, the low and high bands are shelving filters, while the mid band is fully parametric.
What is parametric EQ?
The parametric EQ is a mainstay of recording and live sound because it offers continuous control over every parameter. A parametric equalizer offers continuous control over the audio signal’s frequency content, which is divided into several bands of frequencies (most commonly three to seven bands).
What is broad bandwidth?
A broad bandwidth accentuates or attenuates a larger band of frequencies. Broad and narrow bandwidths (low and high Q, respectively) are usually used in conjunction with one another to achieve the desired effect. Let’s look at our kick drum again. We have a kick drum that has a great, big, low-end sound centered around 100 Hz and an attack hitting almost dead-on at 4 kHz. In this example, you would use a broad bandwidth in the low-frequency band, centered at 100 Hz, and a narrow bandwidth boosted at 4 kHz. In this way, you are accentuating the best and downplaying everything else this particular kick drum has to offer.
What is Q in EQ?
In equalizers, Q is the ratio of center frequency to bandwidth, and if the center frequency is fixed, then bandwidth is inversely proportional to Q—meaning that as you raise the Q, you narrow the bandwidth. Q is by far the most useful tool a parametric EQ offers, allowing you to attenuate or boost a very narrow or wide range ...
What is a narrow band filter?
A narrow bandwidth (high Q) is particularly useful for removing unpleasant tones. Let’s say the snare drum in your mix has an annoying ring. With a very narrow bandwidth, you can isolate the offending frequency (usually around 1 kHz) and remove, or reject, it. This type of narrow band-reject filter is also known as a notch filter. By notching out the offending frequency, you can remove the problem without removing the instrument from the mix.
