Chapter 1 About the Q10

The Q10 is a multiband paragraphic equalizer that provides up to ten bands of flexible equalization. It is configurable as either two independent mono equalizers or as a precisely ganged stereo equalizer. For years, the Q10 has been the go-to tool for surgical repairs of problematic sounds in the studio and in the field. It is also valuable as a gentle coloring tool. Each band offers six different filter types and complete control of gain, frequency, and Q. Unlike most multiband equalizers, each Q10 band can use any filter type, so there is immense flexibility when shaping a signal. Q10 offers extremely large Q values and large boosts and cuts, so you can fix and focus sounds that a conventional EQ could not touch. It lets you create special effects and spectral modifications that range from subtle to extreme.

Waves introduced the Q10 in 1993 and was the first paragraphic equalizer plugin on the market. It quickly set the standard for multiband EQs and became an industry staple. It has become an essential tool for cleaning and shaping sound. Over the years, there have been a few under-the-hood updates to the Q10, but the look and flow were left largely unchanged. To celebrate the 25th anniversary of this tried-and-true workhorse, we've made some improvements, added a few features, and created a new, modern look.

What's new?

If you're used to the Q10, the 25th Anniversary edition won't present any surprises. Its new functions are intended to provide easier control and better performance. Here are the new features:

• Q10 proportional Q filters: When the Proportional filter type is selected, the Q value is proportional to gain adjustment. As a band's gain increases, the Q value increases and the filter narrows.
• Smoothing: Ensures that sound remains glitch free when controls are moved.
• Double precision processing: Lets you choose between 32-bit floating point processing and double-precision 64-bit processing.
• Selectable band control: Choose between viewing all parametric band controls in one view or focusing on a selected band. Both views show the complete graphic display.
• A new interface: We've given this tried-and-true warrior a cleaner, easy-to-use interface.

Q10 components

Q10 has a mono component and a stereo component. Controls are identical for each. With either component, you can choose between one, two, three, four, six, eight, or ten bands.

The 25th anniversary edition Q10 offers two interface looks. The default view is a modern interface that resembles other current Waves plugins. You may, however, choose to use the tried-and-true classic Q10 interface. Toggle between the two using the Modern/Legacy button on the WaveSystem Toolbar.

Controls and functionality are very similar in the Modern and Legacy interfaces, and you can switch between one and the other without affecting EQ performance.

Chapter 2 Using Q10

The Q10 interface consists of three sections: a graphic display for viewing and controlling the bands, a parametric EQ section, and input and output sections. Parameters can be entered directly into parametric value boxes and by moving graphic band markers on the graphic display. Changes made on one section are reflected in the other.

Use the value boxes to enter specific values. This is useful when, for example, creating a harmonic filter that has very predictable frequency values.

Drag across the graph to locate sounds "on the fly." When creating a deep cut, it is often useful to use a very high Q and a large boost to find the problematic sound and then turn the boost into a very deep cut.

Using the Parametric Controls

The Parametric Control section is a table with value windows for Frequency, Gain, and Q. A value is shown for each of the equalizer bands, along with the band's filter type and In/Out button. In the Modern interface, there are two Parametric Control views.

Choosing a View

Toggle between the Full and Focused views using the Collapse/Expand buttons on the right side. ➡️

• In Full View the band control for all of the bands are visible. A Q10 will display ten rows of controls, a Q6 will display six, and so forth. This is akin to the classic Q10 band control view.
• In Focused View the band controls of only selected band are shown. This allows for a larger graphic display section and an uncluttered view.

Parametric Controls - Full View

This view displays all band controls in a table format, showing Band number, Gain, Frequency, Q, and Type for each of the ten possible bands.

Parametric Controls - Focused View

This view displays controls for a single selected band, allowing for more detailed adjustment and a larger graphic display area.

Input

Input signal is controlled from the Input Fader on the left side. The input signal should not be excessively loud since, under certain circumstances, internal clipping can occur. With high-level files (already normalized or with high peaks), several situations can occur that can cause peaks that did not exist in the unequalized signal. This is true even for filters that have no gain (e.g. a high-pass filter) or for filters with a cut. To show this kind of clipping, meters would be needed between each band of the equalizer. Therefore, if you are using a sound file with very high levels, reduce the Input faders from -3 dB to -6 dB to allow for internal peaks.

Control the Input level in the DAW or other source, or with the Q10 Input control. In the Full view, this control is presented as a fader or a pair of faders. In the Focused view, the input level is controlled with knobs. Control values are the same in Modern and Legacy views.

Input controls are separate for left and right. To move L/R together, click and draw a box around the two faders or knobs. The controls will move together until you click elsewhere. ?️

Band Control Row

The parametric controls enable you to adjust processing parameters without touching the graph, so it's useful for precise, delicate control. Double-click on a band selector to turn the band on or off. Only one band is selected at a time.

Band On/Off

Each band has an on/off button. Next to it is the band number icon. Turning off a band dims the corresponding band marker in the graph and disables whatever influence the band has on the overall graph. Expect the graph to change when a band is turned on or off. In the Focus view, click on the number button to cycle through all of the bands and correspondingly change the focus. ✔️/❌

When making crucial adjustments it is very useful to listen to the EQ output with individual bands on or off. This provides a very different comparison than bypassing the entire plugin (something you should also do frequently to understand how you are influencing the signal).

Band Number ID

Full view: Function is identical to the Band On/Off button. Focus view: Cycles through the bands. Number indicates selected band. Default: Band 1.

Gain

Band Gain can be adjusted in increments of 0.1 dB, between -18.0 dB and +18.0 dB. Click and drag vertically on the knob or value box to change Gain value. You can also select the value box and type in a number or use the up/down arrows on the keyboard. Gain controls are up/down. ⬆️⬇️

Freq

The Frequency control (Freq) value box displays the center frequency for each band when a bell or bandpass filter type is selected. When in low/high pass or low/high shelf modes, the frequency parameter sets the corner frequency of the filter. Traditionally, the corner frequency of a filter is defined by its -3 dB point.

The Frequency control values are adjustable in one sixteenth tone steps (96 steps per octave), rounded to the closest integer. The left/right arrow keys may be used to step the selected Frequency value in one sixteenth tone increments. Frequency is controlled in the same manner as Gain control, but all adjustments are left/right. ⬅️➡️

Q Control

Q refers to the width of the filter. The higher the Q setting, the narrower the band of frequencies that are affected. For typical EQ applications, Q values between 0.5 and 6 are common. But for specialist applications such as notching out specific frequencies (e.g. hum), much higher values of Q (up to 100) may be used. You may choose to use a high Q setting to locate a specific sound and then widen the filter to achieve a smoother effect.

Filter Type

The Filter Type radio buttons select the type or mode of filter used for each band. The selected type is indicated by an icon representing the filter curve. To select between filter types in the Legacy view, click repeatedly on the Type icon. This will step through the filters in the following order: parametric (bell), low shelf, high shelf, low pass, and high pass. You can also CMD+click (Mac) or Start+click (Windows) on the filter type button to reveal a popup menu of filter types for direct selection.

The default Type is the bell (or band pass) filter, which is used to provide parametric equalization or to construct notch filters.

Band Pass (Bell) Filters

Bell filters boost or cut a certain frequency range. The indicated frequency is the peak of the bell filter, so this is the frequency that will get the most boost or cut from the filter. Bell filters can be wider or narrower according to the defined Q value.

Q is a way to define the frequency width of the boosting or cutting bell filter. It may be represented by the mathematical relationship: Fc/Fw (center frequency divided by frequency width at -3 dB point), both measured in Hertz.

Low Q values yield the widest bells, which are good for enhancing a complete range, similar to Hi Fi tone controls. High Q values offer the narrowest filters, which are useful for eliminating a specific problematic resonance.

Shelf Filters

Like the Pass/Cut filter, the Shelf filter can boost or cut above or below a specified frequency. Rather than rolling off to infinity, the shelf will roll off or up to the designated gain indicated in the shelf.

The Shelf filter's cutoff frequency is located in the middle of the slope. So if the specified frequency is 3000 Hz and the gain is set to +6 dB, then the gain at 1000 Hz will be at about +3 dB, as demonstrated here. The Q control does not affect Shelf filter types.

Cut/Pass Filters

To attenuate unwanted low-frequency audio, such as rumbles, use the high-pass filter. To attenuate unwanted high-frequency disturbances, such as hissing or screeching, use the low-pass filter.

The Pass/Cut filter type has a roll-off response of -12 dB per octave. The cutoff frequency represents the point where the roll-off is -3 dB. The Q control does not affect Pass/Cut filter types.

Proportional Q Filters

If the Proportional filter type is selected, the Q value is proportional to gain adjustment. As a band's gain increases, the Q value increases and the filter narrows.

Proportional Q filters provide a convenient tool for tuning the center frequency of a bell filter. Dial in a high gain and the filter narrows considerably. Locate the correct frequency, then lower the gain, and the filter widens. There are many other applications. Compare the Band-pass filter and the Proportional Q filter to understand how they differ.

Arrow Keys

You can use the keyboard arrows to adjust parameters in a selected value box. Click on a value box or band marker to select it. Left/Right arrows control Frequency or Q, and up/down arrows control Gain. Pressing an arrow key once will change the selected value(s) by the smallest available increment. Press and hold for continuous change. ⬆️⬇️⬅️➡️

Using the Graphic Controls

Adjusting values directly on the Graphical Display is the most intuitive way to use the Q10, since you get immediate feedback. Each band is represented by a band marker with its own number and color. Move the cursor up and down to adjust Gain. Move left and right to adjust Frequency and Q.

Graphic control modifiers

Lock into one parameter without changing the other by holding the Control key down while moving the mouse. For instance, either before or after clicking on a Band Marker, click+hold the Control key. Then, move the mouse to adjust Frequency without changing the Gain. Release the Control key. Then, press it again and this time move the mouse to adjust the Gain without changing the Freq. ?

Channel marker linking

In the stereo component, the two sides of a channel can be controlled together or independently.

The Link buttons beneath the output faders set whether left or right are controlled separately or linked together. When the values of left and right differ you will see their markers diverge. ?

Link/unlink behavior is the Graphic Display and the Parametric section.

Trim

The Trim button is used to adjust the output signal to its maximum level without clipping. In this example, it shows a headroom of 4.5 dB. The value is positive (and the clip light is not illuminated), which means that the faders can be moved upward 4.5 dB without any clipping. This is sometimes called "margin" and simply shows how close the signal has come to 0 dBFS.

To Trim the faders, simply click the Trim button once. The faders will move upward by the value shown in the value box. Maximum positive trim is 12 dB. This results in the highest gain possible without clipping. To reset the output fader, ALT+click on its fader button. Left and Right output faders are adjusted separately, so select both by drawing a box around both faders.

If the output signal is already clipped, the Trim value will be negative and the clip indicator above the meters will be illuminated. Clicking Trim will reduce the fader level by the current over-level amount to avoid clipping.

Presets

Q10 provides a huge selection of factory presets. Use the WaveSystem Toolbar at the top of the plugin to save and load presets, compare settings, undo and redo steps, and resize the plugin. To learn more, click the icon at the upper-right corner of the window and open the WaveSystem User Guide.

Click on the small arrow in the middle of the Toolbar to open the Presets drop-down menu. The Q10 presets can help you in several ways:

• Solve a problem (e.g., "Remove 50 Hz Removal" or "Noise Removal")
• Focus an instrument (e.g., "Guitar Enhance" or "Power Bass")
• Change the attitude (e.g., "Lead Vocal" or "Backing Vocal")
• Create an effect (e.g., "Radio" or "Telephone")
• Learn from the pros. Selected Waves artists have provided their own custom presets that show you some of the ways they use Q10.
• Experiment with the classics. There is a folder called "Legacy" that includes some of the groundbreaking filters that were used in the development of the plugin.

You cannot save a factory present. Instead, load a factory preset, make your adjustments, and them save this as a User Preset. This new preset will appear in the Presets menu. This is described in the WaveSystem User Guide.
