Harmonic Exciter

Harmonic exciters can give a sparkle or shine to the upper frequencies of a mix. They can also be used in mid and even low frequencies to add a boost or presence. Add warmth, sparkle and shine with four separate bands of excitation. Like other multiband modules in Ozone, the multiband harmonic excitation is based by default on the four bands set in the multiband section.

Key Features

  Choose from tube or tape-modeled saturation with adjustable mix controls for each band

  Unique multiband time offset controls for tightening and adding attack to bass and kick

  Mid/side processing lets you add color to different parts of the soundstage separately

• New Saturation meter highlights affected frequencies and a post filter to sculpt the frequency output of the exciter

Ozone Advanced Exclusives:

  New Triode modes simulate the analog warmth of the 12AX7 amplifier tube

Harmonic Exciter

Note: Each band has its own sliders to control the amount of harmonic excitation and the mix of the excited signal with the original signal. 

Exciter Modes:

Retro: Retro mode is based on characteristics of transistors with a slowly decaying row of odd harmonics.

Tape: Tape modeling can be recognized as a brighter sound due to the odd harmonics found in tape saturation models.

Tube: Tube modeling is characterized by its clear "tonal" excitation with an emphasis on dynamic or transient attacks.

Warm: The Warm exciter mode is similar to Tube, but is unique because it generates only even harmonics that decay quickly.

 Triode: Triode mode is modeled after a circuit using a 12AX7 vacuum tube. Triode mode uses one half of the tube for a subtler overdrive than Dual Triode mode.

 Dual Triode:  Like Triode mode, the Dual Triode mode models a circuit using a 12AX7 tube, but uses the entire tube, introducing more pronounced overdrive with a slightly warmer tone.


Exciter Controls

Amount: Controls the amount of the harmonic excitation for the selected band.

Mix: Allows you to control the mix of the excited signal with the original mix.

Delay: Setting the delay for a band offsets this band relative to the other frequencies. To learn how and why this works as an exciter, refer to our online mastering guide.

In general, try offsetting the delay for a low band (<150 Hz or so) by about 1 msec. The low band will get tighter, but probably lower in perceived volume. Because it is tighter in time, though, you can usually compress or increase the gain of that band in the multiband dynamics module to get "punch" without a ringing or "flabby" sound.

Like controls on other screens, you can use arrow keys to adjust a selected slider, or the wheel of a wheel mouse, or double-click on the numeric label and directly enter a value with the keyboard. You can reset a slider by double clicking on it.

Oversampling: Utilizes more processing power to increase quality (CPU intensive). 


Mini-Spectrum Window

The meter at the top of the module defaults to a display of the signal spectrum.  However, with a selection on the left it may also display the Saturation Meter. 

Saturation meter:displays the spectrum of the incoming signal, but additionally highlights particular frequencies being affected by the exciter and features the post filter curve.  The spectrum is drawn in solid green while the frequencies being affected by the exciter are shaded in black.  The post filter is an adjustable high shelf filter on the saturation meter that allows you to adjust the frequency output of the exciter module.

Mid-Side Support

Stereo/Mid-side: This button allows you to switch between "stereo" processing or "mid-side" processing. When "stereo" is selected, the Ozone module will perform basic stereo signal processing. When "mid-side" is selected, all mid-side features become available.  


To make it easier to distinguish between Mid and Side modes, the interface highlights have designated colors. Mid mode is presented as orange, and Side mode is presented as dark blue.

Exciter Mid Processing Mode

Example using Mid-Side Processing in Ozone's Harmonic Exciter

Mid-Side processing allows you to separate a specific frequency range into its Mid and Side components and apply processing separately to the Mid (center) channel, or the Sides of your mix.

For example, using the Side channel in the Harmonic Exciter module (blue), try selecting the upper frequency bands for your mix. By increasing the amount sliders for the upper frequencies you will be applying the exciter to the extreme edges of your mix only and leaving the Mid (center) channel as-is.

 Component Harmonic Exciter Plug-in

If you are using Ozone 5 Advanced you will also have the ability to instantiate Ozone 5's Harmonic Exciter module as an individual component plug-in.  Ozone 5 Advanced includes component plug-ins for all six of Ozone's modules complete with all the same features as the module within Ozone.  Any module presets saved within Ozone will open within the component plug-ins' module preset system.
