Boosting this frequency range can add clarity of the mix or specific sounds, but too much can make an entire track tiresome to listen to. Brilliance or Noise Brilliance or noise ranges from 7kHz to 20kHz. It is quite similar to presence in its use, but the higher end of this frequency range is mostly hisses and noise. NOTE: The above frequency ranges are not set in stone; they are mere guidelines. There can also bit a bit of overlap between these ranges. The same counts for the EQ chart below.
Every heard ringing in your drums? Or how about resonating frequencies in vocals or instruments? You want all elements to sound crisp and clean, and EQ can help you with that. If you want to pinpoint and remove unwanted frequencies, you can make use of a so-called frequency sweep. Set the frequency to a value in the lower end of the spectrum, such as Hz. Apply a high Q setting, such as Step 2: Loop the sound you wish to apply the frequency sweep to and play it. While it plays, gradually increase the frequency.
Step 3: Listen closely. You may find various frequencies that sound awful or ear-piercing as you sweep by them. Once you find one, stop adjusting the frequency. Needless to say, the Gain should end up at minus dB so to counteract the initial frequency overdose. Set Q as you see fit.
Be careful not to overdo it, as the sound may begin to sound very unnatural and plastic. Keep checking if your sound still works well with the rest of the song. In the case of the high end, we mean everything from 4kHz — 16kHz, especially 8kHz and over. Instead of reducing the frequency by a set amount of dB, the Low Cut Filter cuts more per additional octave below the set frequency.
While producing, you may notice that sounds such as pads, synths and FX can carry quite a lot of low end. To make sure your actual sub bass and bass stay well-defined, you can consider cutting the low frequencies of the sounds that are not meant to supply the actual low end of your track. The same principle applies to the use of a High Cut Filter.
Be careful not to cut too much though. Moderation is key. You now know the basics of EQ and how to use it. But we're not there yet, as there are a few things about EQing you need to look out for. So that brings us to the pitfalls of EQ and a bit of advise to help you avoid the mistakes lots of other producers made. Look At The Bigger Picture Especially when you're a starting producer, it's very tempting to use EQ to make a bassline or lead synth sound incredible on its own.
But we have to be honest and say you'd be missing the point of EQ in that case. Even the best sounds in the world are useless if they don't fit your mix, so overdoing on EQ because it sounds nice is generally a waste of effort. Make it your number one priority to EQ in context.
After all, EQ is meant to balance your mix and not to enhance individual sounds. The same principle applies here. When nothing ever sounds good enough to you, remind yourself that making too many EQ adjustments can work sideways.
Because of this, too many alterations can cause it to sound unnatural or even dull.

A parametric EQ gives us continuous control over all the important parameters. These parameters differ depending on the filter type which is often selectable, especially with EQ plugins. The number of bands in a parametric EQ is typically between 3 and 7. We're able to sweep the frequency of a parametric EQ and set it exactly where we need it to be. We can also control the Q parameter and, of course, the amount of gain. A parametric EQ will often feature a high-pass filter and low-shelf option as well as a low-pass filter and high-shelf option, each with adjustable cutoff frequencies.
Some software parametric EQs allow us to change the typical bell-type bands in the centre into notch or band-pass filters as well. What is semi-parametric audio equalization? Semi-parametric EQ sometimes referred to as quasi-parametric EQ offers some, but not all, of the customization of a parametric EQ. Semi-parametric EQs are essentially parametric EQs with a few options missing. Most often, this missing functionality means no Q control. What is dynamic audio equalization?
Dynamic EQ is a type of equalization where the EQ of certain frequencies is triggered dynamically as those frequencies surpass a set amplitude threshold in the audio signal. Dynamic EQ, like a compressor, will have threshold, attack and release settings to alter the EQ of a signal dynamically.
Dynamic EQ is actually quite similar to multiband compression in the way that it attenuates specific bands of frequencies as these frequencies surpass a set threshold. These bands can have any of the filters described above though the options of a particular dynamic EQ unit depend on the design of such a unit. Unlike a multiband compressor, a Dynamic EQ doesn't split the signal into bands to begin with. Rather, each EQ band regardless of filter type is only engaged as the frequencies within that band exceed the set threshold of that band.
Dynamic EQs can also boost frequencies as the band exceeds the threshold, whereas a multiband compressor would require expansion to achieve the same thing. To really understand dynamic EQ, we should understand a few more parameters that are often reserved for compression. The threshold is a set level that, when exceeded, causes the EQ to engage on the select frequencies. Note that, within a dynamic EQ, the threshold will be set on a filter-by-filter basis.
The attack is a control that adjusts the time it takes for the EQ to reach its full boost or cut once the threshold is surpassed in the specific bandwidth of the filter. The release is another time control that adjusts the time it takes for the boost or cut to fade back to the original EQ once the level within the filter bandwidth drops back down below the set threshold.
So dynamic EQ does work rather similarly to compression. I like to think of it as a mix of the two. These EQs are generally of the parametric variety but are not static. Rather, they are triggered by the dynamics of the input signal much like a compressor and react accordingly by adjusting the EQ of the signal dynamically. What is a linear phase equalizer? A linear phase EQ is a type of equalization that does not alter the phase relationship of the source.
Achieving linear phase is not possible with analog circuits and has been made possible with computer coding. As we've discussed previously in the section on filters, the reactive components typically capacitors in analog EQs shift the phase of some frequencies in the output relative to the input. This phase shift will affect the sound. In some cases, the phase shift produces sonically pleasing effects, and in many other cases, it doesn't.
An issue with more complex minimum phase filters and EQs is that, while the amplitude graph shows us an expected frequency response, the phase-shift we typically cannot visually see what's happening with phase without an external device or plugin tells a completely different story. We'd only see that we're boosting on an amplitude chart, but we'd really be affecting the signal differently. These filters effectively analyze the frequency content of a signal and apply gain to the appropriate frequencies via FIR finite impulse response filters to eliminate any phase-shifting that arises.
This process is rather CPU intensive and will cause delay in the output signal through latency. To make up for this latency, linear phase EQs will shift the output signal earlier in time. So linear phase EQ essentially trades phase shift for pre-ringing artifacts. This is great for narrow surgical filtering but is likely not as good a choice for gentler equalization and EQ for transient signals like drum tracks.
That brings us to our next point. Linear phase EQs are excellent tools when parallel processing tracks. Since they don't introduce any phase-shift, there will be no unnatural phase-cancellation when the dry and processed tracks are mixed back together. What is a passive equalizer? A passive EQ uses passive filters to sculpt the frequency content of audio signals. However, these equalizers are powered devices and have amplification either tube-based or solid-state to apply makeup gain and even boosting capabilities for the passive filters.
Passive equalization has been around for a long time but has lost popularity as the aforementioned EQ types have come to the market. These EQs utilize passive filters, meaning there are no op-amps or transistors or tubes within the actual EQ portion of the circuits. As we discussed earlier, there are pros and cons to passive filters.
On the plus side, passive filters are simple and offer less distortion overall. They can also be designed with inductors rather than the typical capacitors, which do offer some colouration to the sound, though this colouration is generally pleasant. However, passive filters do attenuate the signal and thereby worsen the signal-to-noise ratio. They also tend to have issues with driving loads of varying impedances.
Fortunately, passive EQs are designed to maintain many of the benefits while mitigating the drawbacks of passive filters. The post-filter rather than intra-filter amplification stage provides a proper load to the filters and makeup gain to bring the level back up to unity or greater. In some designs, the makeup gain can even allow for boosting in the EQ. What is shelving equalization?
Many other articles you'll read on equalizers state shelving EQ as its own type of EQ. Rather, some equalizers offer shelving. With a shelving EQ, you're pretty much limited to adjusting the basic timbral qualities of the audio. That being said, everyone else talks about shelving EQ as its own thing, so I should mention it here. The concept of Q and bandwidth also applies to shelving EQs with higher Q factors yielding a gentler slope up to the full boost or cut.
Very high Q factors will even produce resonances at the top and bottom of the transition period. The Baxandall EQ is a type of shelving EQ that has a broader transition range and gentler rise or fall from the cutoff frequency. This type of EQ yields a more natural sound and minimal phase distortion, allowing users to make more drastic boosts and cuts without negatively affecting the phase of the signal.
What is stereo equalization? What is mid-side equalization? So far, we've discussed what an equalizer is, the different types of equalizers, and how EQ works. Now it's time for the good stuff: how to actually use EQ to get the results we want! If you've made it this far into this article, you'll know how powerful and versatile audio equalization is. A big part of EQ versatility that we have yet to touch on is its different positions within the signal chain.
The audio signal chain is simply the cables, effects, processes, amplifiers, etc. EQ can be used as the first processor to shape an audio track before it reaches any other processors. At the other end of the mix, EQ can be used on the mix bus to help smooth out the entire mix and even during mastering to help finalize an audio product. When it comes to driving loudspeakers, many power amps and receivers will have built-in EQ to allow us to adjust the overall timbre of the audio before it is outputted by the loudspeakers.
Some mixing engineers prefer to use EQ before compression, while others prefer it after compression. It can be used before or after modulation effects, spectral effects and other processes. In a way, microphones are just like our ears. If we jump back to the section A Note On Human Hearing , we'll recall that we do not hear all frequencies across the audible spectrum equally.
We have a frequency response that is more sensitive to some frequencies than it is to others. The same is true of microphones. This frequency-dependent sensitivity is called the microphone's frequency response. Some of this colouration may result in unwanted resonances or lack of information.
When two or more tracks share similar frequency content, they tend to compete to be heard in the context of the mix. The frequency bands that host this build-up of energy will often become muddy. Mirrored EQ is a technique in which one band is boosted in one track while the same band is cut the competing track s.
Here, we see that the pink EQ is boosted around Hz and cut around 2, Hz. The blue EQ is cut around Hz and boosted around 2, Hz. This is an example of mirrored EQ. Ideally, we would want the boosted frequency bands to be within a range that best characterizes the audio it's boosting.
Similarly, we'd want the cuts in the other tracks to be in less important frequency ranges according to the timbre or character of the sound. This is, of course, easier said than down when the whole point of using mirrored EQ is when two or more tracks compete over the same frequencies. However, when done correctly, it can really add much-needed separation within a mix. As sound waves travel naturally, the high frequencies are attenuated at a greater rate. This is because higher frequency shorter wavelength sound waves lose energy faster due to friction as they cause the air molecules to vibrate.
This is part of the physics of sound. In addition to the distance factor, closer sounds are heard as having more pronounced transients the initial attack of a sound. The transient spike of a sound or musical instrument contains a lot of timbral information in the upper harmonics of the sound. By reducing the high-end with EQ, we can effectively dampen the transients and give the illusion of a sound being further away.
When mixing, we can use EQ to attenuate some of the high-end of a track to give it the effect of being further back in the mix. Conversely, we can pull elements closer to the front by boosting some of the high-end. Sometimes audio signals have problem frequencies. These frequencies are irritating or sound bad and give a bad impression of the audio signal and negatively affect the mix as a whole. They often show up as unwanted resonances within the mix. This could be due to the microphone , mic position, room, instrument, synthesizer, plugin or other factors.
Finding and cutting problem frequencies can be down with graphic EQ if the resolution number of bands is high enough and centred correctly. However, it's the parametric EQ that is the best tool for seeking and destroying those annoying resonant frequencies. The best technique here is to first boost a band in the parametric EQ with a fairly high Q factor narrow boost and proceed to sweep the centre frequency slowly across the frequency spectrum.
Listen for any particularly offensive frequencies and roll back the gain so that the EQ cuts those problem frequencies. A similar technique is used for feedback control in live sound situations. Low-end rumble can be present in the source material like a transport truck passing by the studio during a take. It could also be an issue of electromagnetic interference within the studio.
It can even be a buildup of low-end information across several tracks. Essentially, low-end rumble is low-end energy that serves no real purpose in a mix. All it does is eat up precious headroom and give the mix poor sub-bass and bass sound. High-pass filtering, which is commonplace in equalizers, can help us to rid of low-end rumble in tracks that do not need any representation in the bottom end, making more room for the tracks that do kick drum, bass guitar, tuba, etc.
If the low-end is particularly competitive, we can even high-pass some elements higher than their fundamental frequencies without ruining their sonic character. That's because our brains will fill in missing low-end energy if our ears register the signal's harmonics. This is a win-win when it comes to high-pass filtering. We can remove low-end noise without overly affecting our perception of the lower notes of the instruments!
Characteristic frequencies can be the particular formants of certain instruments or vocalists. They can be the fundamental resonance and attack of certain drums; they could be a particularly rich part of the transient harmonic profile or simply a band where the track's timbre sounds better when accentuated.
Accentuating these frequencies with EQ will likely make the track sound a bit better on its own but will also allow it to fit better within the mix, holding its own in the overall response of the entire mix. What is an audio de-esser? This can be achieved using a dynamic EQ, multiband compressor, sidechain compressor with automation in a mix, or manually. Sibilance can be quickly defined as the hissing sound.
Though a necessary part of speech intelligibility, sibilance can often be overly harsh in a vocal track and may require attention to smooth out. Sibilance is typically in the frequency range of 5 kHz to 8 kHz though it may occur below or above that range. A de-esser is designed to reduce the harshness of sibilance by attenuating the sibilant frequencies when they reach a certain amplitude.
That being said, simply duplicating a track and applying a certain EQ curve to the duplicate won't gain us any advantage over simply EQing the original. Cleaner reverb, where the parallel signal is high-passed and then EQed to reduce low-end rumble. This helps to improve the sense of space with reverb without adding more information to the low-end of the mix.
A single track can also be processed by several EQs to great effect. This is what I refer to as serial equalization of a track. By putting EQ in series, we can effectively combine characteristics of multiple EQs on a single audio signal. For example, perhaps we need to get surgical with a digital parametric EQ but want the character and a wide boost from an analog semi-parametric.
We could run the signal through the digital EQ to clean it up and then through the analog EQ to really shape it to our liking. When using equalizers in series, we can also reduce the workload on any particular equalizer. Perhaps an EQ begins to sound unnatural beyond a certain cut or boost.
Give the signal an extra, more natural cut or boost with a wider bandwidth filter from another EQ. Synthesizers often utilize modulation and filters to achieve cool effects think of Electronic Dance Music. The same thing can be achieved by automating various parameters on an EQ. This may seem like more work than it's worth when we have access to filters, envelopes and low-frequency oscillators LFOs , but getting into EQ automation can really yield some awesome effects.
Tone controls are the basic bass, treble and sometimes mid controls. We find them on amplifiers, receivers, audio effects units, active loudspeakers and more. The tone controls will typically use shelving EQ for the bass and treble and a bell-type filter for the mids if the mids are controllable. Crossover networks are designed with band-pass filters that split the input signal into several bands.
Crossovers are also used in multiband compressors to separate the bands for each individual compressor circuit effectively. They're also used in vocoders to split the modulator and carrier signals into a set number of bands.
EQ is an invaluable tool for controlling feedback in live environments. There will be an opportunity for standing waves and other resonances to occur in any closed acoustic space. These standing waves can easily be picked up by microphones and sent into a feedback loop with the loudspeakers.
This will reduce the likelihood of feedback and won't add additional resonance to the already-resonant space. Anti-aliasing filters are analog low-pass filters that are used at the input of analog-to-digital converters ADCs. These filters restrict the bandwidth of the signal in an effort to satisfy the Nyquist-Shannon sampling theorem. Without getting too far into it in an article about EQ, the Nyquist-Shannon sampling theorem essentially states that a digital sampling system must have a sample rate at least twice as high as that of the highest audio frequency being sampled.
Note that the This is a bit above double the 20 Hz audible limit. If the Nyquist-Shannon sampling theorem is not upheld, then aliasing will occur. Aliasing happens when the sample rate cannot effectively keep up with the frequency of the sampled audio signal, leading to misidentification of signal frequencies and distortion.
Reconstruction filters are also analog low-pass filters but are found at the output of digital-to-analog converters DACs. A reconstruction filter also known as an anti-imaging filter helps prevent imaging, which is effectively the reverse process of aliasing. Ideally, both filters should be brickwall filters , constant phase delay in the passband with constant flat frequency response, and zero response from the Nyquist frequency.
In an ideal world, both anti-aliasing and anti-imaging filters would be brickwall filters. However, this is impractical with analog filters, so oversampling is used to give some room for error. In theory, running a signal chain with an input, pre-emphasis process, de-emphasis process, and output would give us the same results as running the input straight to the output. The process es put between the pre and de-emphasis processes will benefit from any pre-emphasis processing.
Still, the ultimate output signal will not, thereby requiring any pre-emphasizing to be counteracted with a de-emphasis process. Pre-emphasis and de-emphasis filters are commonly used to enhance FM radio transmission of audio and audio storage on vinyl records. In either case, the pre-emphasis filter is a high shelf boost or high-pass filter , and the de-emphasis filter is a low shelf boost or low-pass filter. Whatever the filters are, they are set to be the exact opposite of one another.
FM radio transmission noise will affect the higher modulation signal frequencies more than the lower frequencies. To combat this noise in the high-end, a pre-emphasis high-shelf boost or high-pass filter will be applied to amplify the high-end frequencies, thereby improving the signal-to-noise ratio.
Once the FM transmission is received, an inversely proportional de-emphasis filter high-shelf cut or low-pass filter brings the audio signal back to its original frequency response. The same is true of vinyl records which are notoriously bad at storing low-end information. A pre-emphasis filter is used to drop the low-end and raise the high-end for storage. We can see this visualized in the plot below:. It is represented by the image below, with the blue line representing the playback de-emphasis EQ and the pink line representing the recording pre-emphasis EQ.
EQ is a powerful standalone tool but is also used, in some capacity, in other audio effects. These additional effects are worth mentioning to make this a complete guide. What is an envelope filter in audio? Envelope filtering is the filtering triggered by the envelope or transients of a signal. These filters, therefore, act according to the dynamic rise and fall of a signal and are most often used on bass, guitar and synthesizer instruments.
Envelope filters use EQ in the form of band-pass , high-pass or low-pass filters. These filters can be swept upward or downward, according to the detected envelope of the input signal, for a variety of effects. For example, let's consider an envelope filter that utilizes a low-pass filter and an upward sweeping direction.
The envelope detector would create an envelope according to the input signal's amplitude and sweep the filter EQ upward and back down according to the envelope. This can be visualized below:. What is the audio wah effect? Wah or Wah-Wah is a filtering effect that is common on guitars and keyboard instruments. The modulation of the EQ peak caused by the effect is designed to resemble the movement of formants in the natural response of the human voice. Unlike the envelope filter effect , which detects and utilizes the input signal's envelope, the wah effect relies on an expression control to sweep its EQ resonance peak s.
Oftentimes, the wah effect will use a sweepable low-pass filter or a band-pass filter with a notable resonance peak in the cutoff frequency or centre frequency , respectively. The yellow response curve represents the heel-down position, while the dark blue response curve represents the toe-down position.
The other curves represent certain instances during the sweep. What is the phaser effect in audio? Phaser is a modulation audio effect whereby a series of peaks and troughs are produced across the frequency spectrum of the signal's EQ. These peaks and troughs vary over time, typically controlled by an LFO low-frequency oscillator , to create a sweeping effect known as phaser.
The phaser effect causes a series of notches to sweep across the frequency response, creating a unique effect. Rather, when it comes to phaser and its relationship to EQ, the phaser effect utilizes all-pass filters. As we've discussed, an all-pass filter allows all frequencies to pass hence the name but does affect the phase relationships of the frequencies across the spectrum. Once again, this is achieved by duplicating a signal and passing one copy through a phase inverter.
The two copies are then sent through a crossover one signal is high-passed and the other is low-passed so that all frequencies get through without any alteration in EQ. This is shown in the following images:. A phaser will work with two signal paths. For every 2 APFs, there will be 1 notch in the resulting frequency response of the output as certain frequencies fall out of phase. A simplified phaser signal path can be visualized with the following image:.
Feeding the final all-pass filter output back into the first all-pass filter input will further intensify the effect by producing resonances:. And there we have, as concise and simple as I can make it. Here's an illustration of a simplified phaser signal path.
