EQ & Compression Plug‑ins

Oct 31, 2017  20 Nov 2017 DMG Audio releases TrackComp Compressor Plug-in with Intro Offer 31 Oct 2017 DMG Audio release Track Range - 5 Plug-ins (incl. A freebie) 15 Dec 2016 DMG Audio Updates All Plug-ins 28 Sep 2016 DMG Audio Updates All Plug-ins 09 Mar 2016 DMG Audio updates Limitless - The Master Limiter for Mac & Win to v1.0.2. Dave has worked in Pro-Audio for over a decade, for prestigious companies such as Focusrite, Novation, Sonalksis, Neyrinck, Brainworx. DMGAudio was created to build the products that we've always wanted; free from the constraints of a board of directors and instead driven by our users.

DMG Audio's innovative plug‑ins combine friendly interfaces with an amazingly comprehensive feature set. Could they be the only EQ and compressor you'll ever need?

Dave Gamble's CV reads like a Who's Who of digital audio. His code has powered plug‑ins from the likes of Focusrite and Sonalksis, but for his latest plug‑ins, he's chosen to go it alone. EQuality and Compassion are, respectively, an equaliser and compressor, and are available in all the major plug‑in formats on Mac and PC. This includes VST3, which means that external side‑chaining is supported in Compassion.

The Universal Equaliser

Dave's goal in developing EQuality has been to create 'a great replacement for all your EQs”. In other words, it's designed to be of sufficiently high quality to be used as a master or bus EQ, yet with a low enough CPU load that you could also use it on every channel of a mix. A lofty goal, indeed!

Certainly, no‑one is likely to find EQuality lacking in the flexibility department. To its four fully parametric EQ bands are added low and high shelving equalisers (which can be switched to bell mode), plus one low-pass and two(!) high‑pass filters. The entire plug‑in can be run in one of five processing modes: the standard Digital, the superior Digital+, plus Minimum Phase, Analogue Phase and Linear Phase. Both conventional stereo and M/S operation are supported, and there are some unique bells and whistles too. The resonant frequency of the shelving equalisers can be separated from the turnover frequency, so that at high Q values you can position the resonant peak exactly as you want it. You can also freely adjust the amount of interaction between gain and Q values, to mimic the behaviour of some analogue designs whereby the bandwidth gets sharper as more boost or attentuation is applied.

The attention to detail extends to the user interface, which boasts a number of clever features. As expected, you can drag the EQ points around with the mouse, and you can also Ctrl‑click and Shift‑click to bypass them and adjust their bandwidth respectively. Metering is also informative and highly configurable. EQuality's metering is highly configurable.Less usually, there's a Range slider that lets you scale the response of every band simultaneously, so you can retain the overall 'shape' of your EQ curve while experimenting to decide how drastic you want it to be. Another neat touch, which I've not seen before in an EQ plug‑in, is the horizontal frequency-shift slider, which allows an existing curve to be moved up or down the frequency spectrum.

The curve itself is drawn very clearly, and you can switch in a detailed spectrum analyser if you want to see the effects of your work in real time. Alternatively, if you prefer not to be distracted by visuals and instead concentrate on how it sounds, you can switch off the graphical display entirely and just use the rotary controls.

My first-choice EQ plug‑in of late has been FabFilter's Pro‑Q, and in use, EQuality struck me as having a lot in common with that excellent equaliser. In both cases, much thought has gone into designing an interface that works well in a DAW environment, rather than mimicking some classic piece of analogue hardware; and in both cases, the results are a resounding success, although I don't think that EQuality's GUI quite approaches the slickness of FabFilter's offering. Here, all the EQ bands and their associated controls are always visible, which makes things a little busy by comparison, and because their respective colours don't quite match, I sometimes found myself losing track of which EQ 'blob' corresponded to which set of controls. Nevertheless, it's still a joy to use for the most part, and the Scale and Range sliders are great additions.

In sonic terms, meanwhile, I think it also bears out its maker's claims for it. The basic Digital mode is not quite as smooth as Pro‑Q's default mode, but is probably less CPU‑intensive, and definitely a step up from the EQs bundled with most DAWs. However, I found myself using it mainly in the other processing modes. Digital+ seems a little more focused than the basic mode, while Analogue Phase seems somehow 'softer' and kinder to the source material. On the master bus, I thought the extra CPU load of Linear Phase mode was well worth while, bringing a noticeable extra degree of clarity to the proceedings. I would certainly be very happy to use EQuality as my only EQ on a mix.

Sympathy For The Level

Audio

EQuality is undoubtedly one of the more comprehensive equaliser plug‑ins around, but Compassion makes it look positively Spartan. Dave Gamble has thrown the kitchen sink at this one, and followed it up with the dishwasher and tumble drier. So bristling is it with features, in fact, that even summarising them would take a lengthy couple of paragraphs.

In essence, Dave's aim has been to create a single compression 'engine' so flexible that it can be tweaked to behave like almost any hardware compressor, as well as doing a great deal that no hardware unit can. To take but a small example, many compressor plug‑ins let you adjust the extent to which the left and right side‑chain signals are summed, to control the degree of stereo linking, but Compassion goes several extra miles. To adjust the stereo linking, you move two dots around on an X‑Y graph, which allows you to set a separate L/R sum for each channel of the mix. You could even set one channel's side‑chain to be influenced only by the opposite channel's signal if you wished, an idea that raises particularly interesting possibilities in Mid/Side mode (which is, naturally, supported).

Likewise, side‑chain EQ is a common feature of dynamics plug‑ins, but not as implemented here. To mimic the behaviour of some analogue compressors, you can bleed noise into the side‑chain signal, either pre‑ or post‑EQ; you can also combine internal and external side‑chain signals. On top of that, there's a second pair of high- and low‑pass filters that sits in the signal path itself, and, optionally, the side‑chain path as well. You can even choose to have the compressor act only on the filtered signal, leaving the rest of the audio alone, enabling Compassion to be used as a dynamic equaliser or a sophisticated de‑esser.

The attack and release parameters, meanwhile, are almost absurdly configurable. You can specify a 'curve law' that modifies the 'shape' of the response to transients, decouple and reverse the order of the attack and release circuits, and introduce a Hold parameter to delay the onset of the release phase. There's also an adjustable auto‑release algorithm. Should the transients themselves be disobliging enough to escape the attention of the main compressor circuit, you can also engage a fully specified transient shaper and peak limiter, each of which has more parameters of its own than some dedicated plug‑ins do.

The behaviour of the threshold and ratio parameters can be tuned in yet more different ways, some tailored towards the possibility of mimicking typical analogue circuits, others offering advanced dynamic control. A variable knee control is joined by a Bleed parameter, which can help create a Dbx‑style 'over easy' effect, plus a Hysteresis parameter that offsets the threshold values for the attack and release circuits. You can specify a Ceiling, or maximum amount of gain reduction, and a Ceiling Curve that governs whether this operates as a 'brick wall' or as a gradual limit. A complementary Depth parameter specifies a maximum amount of gain reduction that will be applied when Compassion is used as a gate or expander.

Here, Compassion is serving as a dynamic EQ on a drum bus, side‑chained from the vocal track.By now, I doubt that anyone will be surprised to learn that Compassion can be used as a gate or expander, but, once again, its versatility is impressive. It can, in fact, simultaneously perform conventional expansion or gating, upward expansion (which increases the dynamic range of signals above the threshold) and upward compression (which squashes and makes louder the audio below the threshold, while leaving peaks untouched). The main Ratio control, meanwhile, runs from 1:1 at the leftmost extreme, through infinity:1 (hard limiting) at about two o'clock and then into negative compression, where the gain range of the signal is inverted. This is something I've only seen before on a few compressors, perhaps most famously the Eventide Omnipressor, and although you wouldn't want to use it every day, it can make for some interesting special effects on percussive sources. If there's one thing that's missing, it's the ability to set a different threshold level for the expander from that used by the main compressor. This can be a useful feature where, for example, you want to compress signal peaks while reducing low‑level noise, but leave the central part of the dynamic range alone.

Of course, no‑one would want to manually set every single Compassion parameter every time they used it, so as well as supporting conventional preset saving and loading, Compassion also incorporates what DMG call 'mods”: the ability to store a chosen subset of parameters. For example, if you've hit upon the perfect combination of behind‑the‑scenes tweakage to recreate an 1176 in every detail, you could store those tweaks as a mod, then simply use the Attack, Release and Threshold controls to set up your virtual vintage compressor for a particular track.

On The Surface

If that massive array of subtleties all sounds a bit intimidating — and it certainly did to me — it's a relief to learn, on first loading up the plug‑in, that you don't have to concern yourself with any of it if you don't want to. The basic Compassion screen simply shows the most important, conventional compression controls, along with a very distinctive graphical display. This, again, is slightly reminiscent of the scrolling display in FabFilter's Pro‑C compressor: the input waveform scrolls from right to left, while above and below it the amount of gain reduction is illustrated by the thickness of a coloured band that is alternately green or red, depending on whether the compressor is in its attack or release phase. The threshold level is shown by a white line, and you can choose to view the input or side‑chain waveform superimposed on the output waveform if you wish. It takes a while to learn how to get the best from such a display, and personally, I found I needed to choose a slower 'logging speed' in order to comprehend what was going on. Fortunately, it's joined by a very configurable and much more conventional bar‑graph meter, and you can switch it off if you want. The many extra controls for detailed configuration are accessed in an optional panel below the main window, where they are organised into a number of panes.

Compassion also features a well‑specified transient shaper and peak limiter.Attempting to describe the sound of Compassion is a bit like nailing the proverbial jelly to the wall, because it's designed to have any sound you want it to have. Its flexibility is illustrated by the supplied mods, which turn it into everything from a FET design to an optical compressor to a vari‑mu valve circuit, and much more besides. Even without tweaking, it delivered a creditable performance across the mix bus, imparting a smooth and slightly dark tone to a rock track — and I'm sure that, with tweaking, it could be made to respond in a hundred other ways. On instrumental tracks and vocals, I was particularly impressed by the lack of unpleasant side‑effects, even with very fast attack and release times. If you're simply after transparent dynamic control, Compassion will do that with aplomb; if you want something more characterful, all the tools are there, though figuring out how best to use them for yourself takes time. (Of course, unlike some dedicated emulations of specific pieces of analogue hardware, it won't reproduce the additional non‑linearities associated with transformers or valve output stages.)

The sheer flexibility of Compassion also means that it shines in problem‑solving roles where other compressors simply wouldn't work. For example, I was mixing a multitrack recording of a band that I'd made live, where drum spill on the vocal mic was proving a big problem. The drums sounded fine until I faded up the vocal, whereupon they acquired a nasty, trashy ring at 2kHz. I was able to deal with this to some extent by using Compassion as a dynamic equaliser on the drum bus, side‑chained from the vocal track. The vocal was fed into Compassion's side‑chain, where it was filtered; I then set up the main Compassion EQ to isolate the 2kHz region and only compress that. The result was that when automation lifted the vocal fader, and with it the 2kHz drum spill, the same frequency range was compressed on the drum bus itself: the results were far from perfect, but did seem to keep the overall tone of the drums a little more consistent.

Although it's very different in look and feel, the philosophy behind Compassion reminds me a little of McDSP's long‑established Compressor Bank plug‑in bundle. That, too, aims to use a single algorithm both to provide versatile dynamic control and to recreate the idiosyncrasies of hardware compressors. Compassion ups the ante even further in the features stakes, however, and is also more widely available than Compressor Bank, which is Mac‑only and doesn't support VST.

Quality‑wise, then, I would have no qualms at all about using Compassion as my only compressor, the more so since it can handle gating, expansion, dynamic EQ and transient shaping as well! On my system, however, I found that its impressive feature set brought with it a rather higher CPU load than most generic dynamics plug‑ins, so I gravitated towards using it only in the most important or challenging mix roles.

Overall, both EQuality and Compassion are up there with the best plug‑ins of their type I've tried, and as such are priced pretty keenly. If you like the idea of having one EQ or compressor to 'rule them all', rather than a number of different plug‑ins for different purposes, they fit the bill admirably.

Pros

  • EQuality is a nice‑sounding and very flexible EQ that can operate in CPU‑light Digital mode and a variety of others, including Linear Phase.
  • Compassion is extraordinarily powerful: quite possibly the most versatile dynamics plug‑in yet created!

Cons

  • Compassion's power brings with it a relatively high CPU load.

Summary

If EQuality and Compassion can't do what you want, you have a problem no EQ or compressor can solve!

EQ Plug-in For Mac OS & Windows

Whatever you look for in an equaliser, you'll find it in DMG Audio's astonishingly comprehensive Equilibrium.

In a world awash with plug-in equalisers, what makes us choose one rather than another? For some people, everything else comes second to the way an EQ sounds, whether that means accurately recreating some treasured piece of vintage gear or imposing the most transparent possible tonal correction. For others, it's the user interface that is of primary importance, enabling them to get the right results as fast as possible. Still others prize flexibility above all, seeking tools that can do everything from super-narrow notch filters to obscure resonant shelves.

DMG Audio's aim with Equilibrium is to satisfy all of these users, and it could be argued that this is a plug-in that offers unprecedented riches in every department. You don't need more than a quick browse of the manual to realise that Equilibrium is unquestionably the most heavily featured and the most flexible equaliser ever made, and not by a small margin.

Mix & Match

Following the likes of Waves' H-EQ and Sonoris's Parallel EQ, Equilibrium permits you to freely mix bands that use different EQ shapes and algorithms, but the menu on offer here dwarfs that available in any other plug-in I know of. Each instance can contain up to 32 shelving, filtering, notch or peaking bands, operating in series or in parallel. They can employ accurate models of vintage hardware EQ circuits, a wide range of digital algorithms, and idealised circuits that suffer none of the compromises inherent in analogue implementation. Up to eight channels can be processed simultaneously, in a variety of stereo configurations. The plug-in as a whole can operate in linear-phase, minimum-phase, analogue modelled and 'free phase' modes, with a variety of different trade-offs between ultimate sound quality, CPU consumption and latency on offer. In 'free phase' mode, you can configure the phase response on a per-band basis, and even manually adjust the shape of the impulse response that is generated for an individual EQ band. In 'free phase' mode, you have control over the phase response of each EQ band, as well as various options allowing you to adjust the impulse responses that are generated. Oh, and each instance of Equilibrium supports not only A and B settings pages for comparison, but C, D, E, F, G and H too!

There is also a great deal of flexibility about how all this power is accessed. You can have Equilibrium present itself as an old-school equaliser, where everything is controlled by knobs, you can enter precise values in text boxes, you can see your EQ bands as notes on a musical scale, and they can be displayed as graphical curves. Not only do these have the usual centre points that can be picked up and moved around using the mouse, but also floating tooltips that appear when selected, allowing you to change their shape, algorithm and so on. The same graph that shows the EQ curves can simultaneously display a wide variety of spectral analyses showing the input or output signals, or both, and can be zoomed to focus on a particular frequency region. There are also comprehensive metering options. From a visual point of view, the only thing you can't do is make Equilibrium into a simulacrum of a hardware rack unit or channel strip, which is fine with me.

In total, there are literally hundreds of configurable parameters affecting both the sound of the EQ and its user interface. This is a plug-in that can be modified on an unprecedented scale and level of detail. To give you an idea, the 'Graph' submenu of the GUI preferences alone contains 19 options, including minutiae such as how the background should be rendered, 'whether un-bypassing a group of bands can start a group drag”, whether the EQ bands are shown filled or outlined, and if the former, how transparent the fill should be!This is just a small selection of Equilibrium's GUI preferences.

Wizard Ideas

As you'd expect, the provision of configurability on such a level has the potential to intimidate users, but DMG Audio have put a lot of thought into making sure this doesn't happen. Equilibrium is thus the first plug-in I've ever seen that has its own Setup Wizard. This enables you to make broad-brush settings by answering a short series of simple questions such as whether you are expecting to run lots of instances in a busy mix, or whether you want ultimate sound quality for mastering. The settings the Setup Wizard determines can then be fine-tuned later through the plug-in's preferences. The Setup Wizard takes nearly all of the hard work out of setting up the plug-in to your taste, and in practice, there were only a couple of times when I found myself struggling to track down the correct preference to deal with some bit of user-interface behaviour I wanted to change. Equilibrium has its own Setup Wizard.

I can imagine that many people would want to employ different Equilibrium configurations almost as two or three different plug-ins, for different applications. You might, for example, want one set of display and DSP preferences for mixing and another for mastering. This is made possible by the ability to load only selected aspects of a preset: you can, for instance, recall the display configuration from a saved preset without recalling its actual EQ settings.

Every EQ In One

In short, then, Equilibrium leaves all other EQ plug-ins in the dust when it comes to features and flexibility, and DMG have done a good job of packaging this power in an interface that makes it accessible and reasonably straightforward to use. So how does it sound? Well, the only real answer is that it sounds like you want it to sound. Even in its least CPU-intensive mode, it's hard to fault the audio quality, while mastering engineers and other obsessives can tweak it to the point where its accuracy approaches the limits of what is theoretically possible in a digital algorithm. If character is what you want, its recreations of classic analogue hardware EQ curves seem very plausible to me, although, of course, there's no modelling of non-linear factors such as transformer or tube distortion, as you might find in a dedicated emulation of a hardware unit.

As an example of what's possible within a single instance of Equilibrium, one of my test tracks was an acoustic guitar recorded through a cheap DI box. Some sort of interaction between the pickup and the DI had resulted in an almost complete null at 800Hz; there were several nasty resonances in the 10kHz region; the low end was boomy and ill-defined; and, as is usual with piezo pickups, the mid-range was honky and in need of overall tonal correction.

The high-frequency resonances were very narrow, to the point where they wouldn't show up on the analysers built into some EQ plug-ins. Equilibrium's zoom controls made it child's play to exclude everything below 8kHz and focus in tightly on the problem region, whereupon I could introduce notch filters at the offending frequencies. At the other end of the spectrum, Equilibrium gave me a huge range of high-pass filter and low-shelf shapes to choose from, making it straightforward to achieve exactly the right degree of control. To address the hole at 800Hz, I had the option not only of numerous conventional peak or bell bands, but of DMG's 'flat top' shape, which can be adjusted to behave almost like a band-pass shelving filter. And, of course, I was equally spoiled for choice when manipulating the tonality of the mid-range.

But that's not half the story, and I could have gone much further. For example, a well-known side-effect of linear-phase EQ algorithms is 'pre-ringing', which tends to be more audible at lower frequencies. In Equilibrium, I could have set my high-pass filter to operate in conventional minimum-phase mode, to avoid audible pre-ringing, while using the other bands in linear-phase mode. Had there been a need for more gentle and musical tonal shaping in the mid-range, I could have combined a high-pass filter in series with peak and shelving bands run in parallel. And if one particular bass note had been boomy, I could have used Equilibrium's musical keyboard to track it down. I could even have set up multiple bands targeting the fundamental and the harmonics, and grouped them to be moved up and down with one swoop of a mouse. The possibilities are truly endless, and the only real down side to Equilibrium's unparalleled flexibility is the endless temptation to persist in tweaking settings, in the hope of making it sound even better!

Pros

  • The most comprehensively featured equaliser ever made, bar none, and by a very long way.
  • Highly configurable user interface and Setup Wizard do a good job of making its power accessible.
  • Full support provided for surround formats up to 7.1.

Cons

  • With this much flexibility on offer, you need to exercise a bit of self-discipline to know when to stop fiddling with EQ bands and make some music!

Summary

DMG Audio's incredibly comprehensive plug-in is far more than just an EQ: it's every equaliser you can think of, rolled into one.
