About FabFilter Pro-Q 3

3

Since its original release in 2009, FabFilter Pro-Q has become the trusted workhorse EQ plug-in for many engineers and producers around the world, widely praised for its superb workflow, excellent sound quality and extensive feature set. With version 3, we're bringing Pro-Q to a new level, introducing features like dynamic EQ, surround support up to Dolby Atmos 7.1.2, per-band mid/side processing, and much more.

FabFilter Pro-Q 3 gives you the highest possible sound quality, a complete feature set, and a gorgeous, intelligent interface that is designed to help you get 'that' sound quickly and easily.

New in version 3

At first glance, FabFilter Pro-Q 3 looks quite similar to its predecessor. But looks are deceiving! Of course, the clean design and intelligence of Pro-Q 2 is still present, but a lot of exciting new functionality has been added to improve your sound and workflow:

Dynamic EQ for any of the 24 bands (Shelf or Bell at any slope), with Dynamic Range and Threshold

controls and an intelligent Auto Threshold mode.

Dynamic EQ bands still feature perfect analog EQ shape matching and also support Linear Phase mode.

Easily create dynamic bands in the EQ display by holding the Alt key while dragging the result curve or double-clicking in the display.

Surround support (up to 7.1.2 Dolby Atmos), with intelligent per-band speaker selection.

Per-band mid/side or left/right processing options.

New Brickwall LP/HP filter slope.

New Flat Tilt filter shape: a flat tilting correction curve over the whole audible frequency spectrum.

Improved spectrum analyzer with frequency collision indication and the option to show the spectrum of

any other Pro-Q 3 instance: simply hover over the analyzer button in the bottom bar and choose another

Pro-Q 3 plug-in instance here. Instances are named automatically and can be renamed if needed.

Improved EQ parameter value display with bypass, shape and delete buttons and easy access to the band menu.

Improved Spectrum Grab with labels indicating the most important peaks.

Improved EQ band menu (also accessible via the value display), with Make Dynamic, Invert Gain options and more.

Improved EQ Match, adding the possibility to match with a post spectrum from another Pro-Q 3 instance in your session.

Other key features

And of course, all the goodness of the Pro-Q 2 is still here: highest possible sound quality, Natural and Linear Phase processing, univeral slope support for all EQ shapes, EQ match, a gorgeous, resizeable interface with full screen more for easy and precise editing, up to 24 EQ bands, intelligent band solo mode, stereo or mid/side processing, intelligent multi-band selection and editing for maximum ease and efficiency, spectrum grab, GPUpowered graphics acceleration, double-click text entry of parameter values, different display ranges: 3 dB and 6 dB ranges for mastering, 12 dB and 30 dB for mixing, Pro Tools hardware control surfaces support, MIDI Learn, undo/redo and A/B comparison, and an extensive help file with interactive help hints.

Upgrading to Pro-Q 3

Upgrading from Pro-Q version 2 to the new Pro-Q 3 is safe and easy: installing Pro-Q 3 will not replace or delete the previous Pro-Q 2 and Pro-Q version 1 plug-ins. All versions will co-exist and can be used at the same time. This ensures that you can open old songs that use Pro-Q 2 or Pro-Q 1 without problems! Of course, FabFilter Pro-Q 3 opens all presets from Pro-Q 2 and Pro-Q 1 without problems. See Upgrading to Pro-Q 3 more information.

FabFilter Pro-Q 3 is available in VST, VST3, AU (Audio Units), AAX Native and AudioSuite formats (all both 64bit and 32-bit).

It is easy to control FabFilter Pro-Q 3's parameters with the large round knobs. They will light up when you move the mouse cursor around to indicate that you can adjust them. The moment you move the mouse cursor over a knob, a parameter value display will pop up, which shows the name and the current value of the parameter.

All knobs support four ways of control:

1. Vertical mode Click on the center area of a knob and drag up or down to rotate it. The knob reacts to the speed with which you are dragging, so if you move the mouse slowly, you make precise adjustments.

2. Rotate mode Grab the arrow of the knob and drag it around. By moving the mouse cursor further away from the knob while dragging it, you can make precise adjustments.

3. Mouse wheel mode Perhaps the easiest way to make adjustments is by using the mouse wheel when you hover over a knob. This mode works for all the knobs and possible panning rings. (On Windows, you might need to click in the plug-in interface first to make sure it is the active window.)

4. Text entry mode Double-click a knob to enter an exact value using the keyboard.

Tips

To reset a knob to its default position, hold down the Ctrl key (Windows) or Command key (macOS) and click the knob once. Note: In Pro Tools, Pro-Q 3 uses the default Pro Tools keyboard shortcut for reset: Alt+click.

To fine-tune a value when using vertical drag mode or the mouse wheel, hold down the Shift key while dragging or moving the mouse wheel. Note: In Pro Tools, Pro-Q 3 uses the default Pro Tools keyboard shortcut for fine tune: Ctrl+drag on Windows or Command+drag on macOS.

There are several handy shortcuts in text entry mode. With frequency values, you can type e.g. '1k' to set the value to 1000 Hz, and also 'A4' for 440 Hz, or even strings like 'C#3+13'. With dB values, you can type e.g. '2x' to get +6 dB (the value that corresponds to two times louder). With all values, you can also type a percentage (e.g. '50%' will put a knob exactly in the middle position).

Sometimes, knobs in our plug-in interfaces are linked: these be adjusted simultaneously by holding down the Alt key (Shift key in Pro Tools) while dragging on one of them. For example, an output level and input level setting of a plug-in could be adjusted simultaneously (in the opposite direction) this way.

Band controls

11

When you select EQ bands in the interactive EQ display, the floating band controls will automatically appear, right under the selected bands at the bottom of the display. The band controls show the current settings of the selected EQ bands and enable you to adjust them precisely.

From left to right, the following settings are available:

The bypass button at the left top lets you easily bypass the selected EQ bands. Note that you can also bypass an EQ band by Alt-clicking its dot in the display. While an EQ band is bypassed, it is dimmed in the display and a red light glows in the bypass button.

The shape button selects the filter shape of the selected bands:

1. Bell, the traditional parametric EQ shape and probably the most versatile of them all

2. Low Shelf, to boost or attenuate low frequencies

3. Low Cut, to cut all sound below the filter frequency

4. High Shelf, to boost or attenuate high frequencies

5. High Cut, to cut all sound above the filter frequency

6. Notch, to cut a small section of the spectrum

7. Band Pass, to isolate a section of the spectrum

8. Tilt Shelf, to tilt the spectrum around a certain frequency

9. Flat Tilt, to tilt the spectrum using a flat curve, around a certain frequency

Note: you also change the shape of an EQ band by Ctrl+Alt-clicking its dot (Command+Alt on macOS) in the display.

The slope button below the shape parameter sets the steepness of the filter from 6 dB/octave to 96 dB/octave (and even up to Brickwall for Low Cut and High Cut filters). In Pro-Q, the slope not only applies to the usual Low Cut and High Cut filters, but to all filter shapes! This allows you to make highly surgical adjustments if needed. So for example, you can make ultra-narrow Bell or Notch filters or very steep Shelving filters.

The frequency knob sets the frequency of the selected band between 5 Hz and 30 kHz. If multiple bands are selected, they are adjusted in parallel.

The gain knob sets the gain in dB of the selected bands between -30 and +30 dB. This setting is only used for Bell and Shelving filter types.

The dynamic range ring sets the range of dynamic EQing in dB, ranging from -30 to 30 dB (possibly limited by the gain setting limits). Choosing a positive or negative dynamic range will make the band dynamic and expose additional dynamic controls. This setting is only available for Bell and Shelving filter types. See Dynamic EQ

The Q knob sets the bandwidth of the selected bands, widening or narrowing them. The Q cannot be adjusted when a 6 dB/octave slope is used.

Note: Because there are different interpretations of Q values in various EQ plug-ins and scientific papers, we have chosen the value 1 to correspond to the default bandwidth. For the shelf filters, the internal Q values are chosen such that they result in a good range of shelf shapes. Keep this in mind when trying to reproduce the filter shapes of another EQ plug-in in Pro-Q: the interpretation of the Q values might not be the same.

Using the Gain-Q interaction button, between the gain and Q knobs, you can enable a subtle, analogEQ-like gain-Q interaction. When enabled, Q and gain influence each other in a pleasant way often found in analog mixing consoles. Essentially, this means that the Q automatically gets a bit narrower when gain is increased, and the other way around, a little gain is added when the Q gets very narrow.

.

Note: Gain-Q interaction only affects the Bell filter shape. Pro-Q remembers the last Gain-Q interaction

setting that you've chosen and will use this for new instances of the plug-in.

12

The previous- and next band buttons let you step through the current available bands in the display, in the order in which they currently appear in the display. In between, the band number of the current band is shown to help you to identify this band in the host when automating EQ parameters.

Note: When creating new bands, they will be numbered 1, 2, 3 and so on. But when you delete a band, the others won't renumber, in order to ensure that currently written automation in your host still controls the correct band.

The delete button at the right top removes the selected EQ bands. If you have accidentally deleted some bands, you can easily restore them using the Undo

button at the top of the plug-in interface.

The stereo placement button controls which channels are affected by the selected bands. The split button (scissors icon) splits the selected bands into L and R (or M and S) bands. See Stereo options When using Pro-Q on a surround channel, the stereo placement button will open a panel with more extensive stereo placement and speaker selection setting. See Surround

.

Tips

Double-click any knob to enter the value directly using the keyboard. See Knobs for more information. For the Frequency knob, you can enter values in various ways, like "100" or "2k", but also "A4" or "C#2+13".

To hide the band controls, simply deselect all bands by clicking on the display background.

Hold down the Alt key while changing the gain or dynamic range knobs in a reverse-linked way (i.e. to trade gain for dynamic range).

Dynamic EQ

13

One of the most important new features in Pro-Q 3 is dynamic EQ: any of Pro-Q's bands (with Bell or Shelf shapes) can be made dynamic, at any slope, with perfect analog matching

Simply put, dynamic EQ changes the gain of an EQ band dynamically, depending on the level of the input signal. This makes it possible to perform subtle and surgical edits similar to a multi-band compressor, but in a way that's often more intuitive and easier to work with.

Since Pro-Q is used by many engineers and producers worldwide as their standard workhorse EQ, we have ensured that Pro-Q 3 remains very lightweight and ultra-fast to work with, keeping the existing natural workflow and shortcuts. Dynamic EQ in Pro-Q 3 is an intuitive and elegant extension of the regular workflow: the dynamic options and controls are only exposed when you actually start using them, and won't get in the way of your normal EQ work.

and in Linear Phase mode.

The dynamic behavior of Pro-Q 3 has been carefully tuned and is highly program dependent: attack, release and knee all depend on the processed audio, the frequency range of the EQ band and the current dynamic range. This results in very natural and smooth sounding compression and expansion, useful for a wide range of dynamic EQing applications.

Creating dynamic bands

Any of Pro-Q's bands can be made dynamic. This can be achieved in different ways:

Select EQ bands in the EQ display, and then adjust the dynamic range ring around the Gain knob in the band controls, choosing a positive of negative value.

Hover above an EQ band in the display, and use the mouse wheel while holding down the Alt key to adjust the dynamic range for this band or the selected EQ bands.

Select EQ bands in the display, and then choose Make Dynamic on the band menu (which you can access by right-clicking the band dot, or via the menu button in the EQ parameter display).

You can also create dynamic bands right away (initialized with a dynamic range instead of normal gain), by holding down the Alt key while creating bands in any of the normal ways: Alt+drag the result curve, Alt+double-click in the EQ display or Alt+Ctrl+click (Alt+Command+click on macOS) in the EQ display.

Internally, the dynamic EQ process will trigger on a band-limited version of the plugin's input, according to the frequency range the band works on.

Dynamic band controls

The following dynamic controls are displayed for dynamic EQ bands:

The dynamic range ring sets the amount of dynamic EQing for a band, ranging from -30 to 30 dB (possibly limited by the maximum gain setting limits). Choose a positive (expansion) or negative

(compression) value here enables dynamic EQing and exposes the additional dynamic controls. Note that

this setting is only available for Bell and Shelving filter types. The current dynamic gain change is shown

as a yellow bar inside the ring, on top of the dynamic range that is indicated in red.

Note that you can also drag the dynamic range indicator for a band in the EQ display adjust the dynamic range.

up or down to

The auto-threshold button toggles the dynamic behavior between the default auto- or custom threshold mode. When in auto mode, the threshold is constantly adjusting to the level of the current, band-limited trigger signal. Click it to enable the custom threshold mode, revealing the threshold slider.

The threshold slider, visible when not using auto-threshold mode, sets the threshold for triggering the dynamic EQ. The level of the trigger signal is shown in the slider, making it easy to find the correct threshold. Note that a soft knee is used internally by the dynamic EQ algorithm, so it can start triggering a little bit below the selected threshold value.

The bypass dynamics button at the left top of the dynamic range ring makes it easy to bypass the dynamic behavior of the currently selected bands. While the dynamic behavior is bypassed, this is reflected in the EQ display, the dynamic range ring is shown as inactive, and a red light glows in the button.

The clear dynamics button will reset the dynamic range to 0 dB for all selected bands, essentially turning them back into normal, non-dynamic bands.

How and when to use dynamic EQ

Generally when mixing or mastering, making static EQ adjustments works very well. But sometimes, using EQ dynamically can be the key to solving specific frequency issues or bringing out certain elements in a mix. For example, you can use dynamic EQ to brighten a kick drum or tame a hi-hat in your drum track, highlighting or suppressing only the transients. Or you could use a narrow dynamic bell filter to suppress sibilance in a vocal recording. Especially in combination with the per-band mid/side/stereo options

, the possibilities are endless.

Pro-Q 3's workflow is perfectly designed for this: you can use it as your go-to EQ on every channel, doing the usual static EQing, but when you need to you can make any band dynamic right away.

Linear Phase processing

Dynamic EQing also works in Linear Phase mode

, but only for Processing Resolution settings up to High. The attack and release response will be slightly different from the normal behavior in Zero Latency and Natural Phase modes.

When using dynamic EQ in Linear Phase mode in combination with the Very High or Maximum resolution settings, you will see a warning sign next to the Processing Mode button to indicate that this is not possible. In this case, simply lower the resolution to High or lower to be able to use dynamic EQing.

Tips

When using the mouse wheel above an EQ band while holding down both Alt and Ctrl (Command on macOS), you change both the dynamic range and gain or the band in a reverse linked way, i.e. you can trade gain for dynamic range.

When you move the mouse cursor near an EQ band in the display, the EQ parameter display pops up showing the current parameter values for the band.

Click and hold the solo button (with the headphones icon) to enter solo mode for the current EQ band. The other EQ bands will dim, just like the yellow overall curve. Simply drag the solo button horizontally to change the frequency of the band, or vertically to adjust the solo listening level.

In solo mode, you don't hear the effect of the EQ band itself, but instead you will hear the part of the frequency spectrum that is being affected by that band. Of course, the frequency range depends on the frequency and Q settings, and is visualized in the display as well.

When using solo mode with Low Cut or High Cut bands, you will hear the frequencies that are being cut away instead of the frequencies that pass, which helps you to determine whether you are cutting the right frequencies.

Generally, solo mode aims to expose the parts of the incoming audio that matter to the current EQ band, but that you can't hear just by listening to the regular EQ sound.

Tips

When using solo with Bell or Shelving bands, hold down Ctrl (Cmd on macOS) while dragging to change the Q, which will of course affect the frequency range that you hear. For filter types that do not have a Gain setting (Low- and High Cut, Notch, Band Pass), dragging in solo mode has the same effect as dragging the normal, changing both Frequency and Q.

You can adjust the solo listening level by moving the mouse up or down while holding the solo button.

If the piano display is enabled, the parameter value display will also show the note number that corresponds to the band frequency.

You can turn the parameter value display on and off by clicking Show EQ Parameter Display in the Help menu.
