Mastering Reverb

Ozone includes a high quality hybrid reverb module that can add a consistent sense of depth and space to a mix.  Utilizing both convolution and algorithmic technologies, the improved reverb module features the warm early reflections of a real acoustic space as well as dense and flexible reverb tails.  It is designed to put a final gloss or sheen on the entire mix while still preserving the sense of space that may have been created by using reverbs on individual tracks.

Key Features

Ozone Advanced Exclusives:

Note: When using the Reverb module, Ozone will consume a significantly higher amount of CPU, especially during parameter changes. To help make Ozone more usable in real time, you can offload some of these changes to prevent the audio from dropping out. See the Reverb Options Tab for more info. 


Early Reflections

Ozone 5 features a number of room modes that control the reverb’s early reflections.  Convolution technology is used to reproduce the acoustics of real spaces.

Early Reflection Modes:

Room – smaller acoustic space with strong and distinct early reflections

Plate – classic reverb effect which captures the vibration of a sheet metal plate when audio is played onto it creating a clean distinctive reverb tone.  Ozone 5’s plate reverb mode was derived from the characteristics of the definitive plate reverb unit, the EMT 140.

Hall – large acoustic space with darker warm reflections

Theater –medium sized acoustic space with dampened early reflections (Ozone 5 Advanced)

Cathedral – larger acoustic space with pronounced bright reflections (Ozone 5 Advanced)

Arena –massive deep acoustic space with expansive density (Ozone 5 Advanced)

Early Reflection Options:

Once an early reflection mode is selected you may adjust the following options that affect it:

Pre-delay: Sets the "pre-delay time", or the amount of delay in milliseconds between the original signal and the beginning of the reverb in order to simulate depth.

 Early Reflection Control: Lowers the level of early reflections in the reverb signal and can be used with pre-delay to create the perception of depth. (Ozone 5 Advanced)


Late Tails

After the initial early reflection, Ozone 5 uses algorithmic technology to simulate late reverb tails.  This allows you to couple the early reflections of one type of space with late reflections associated with another to create unique but realistic sounding reverb.  Once you have chosen an appropriate early reflection, you may adjust the following characteristics of the late tails:

Decay Time: sets the amount of time it takes for the reverb to fully decay

Low Decay: adjusts how quickly the low frequencies decay

High Decay: adjusts how quickly the high frequencies decay

Global Reverb Settings

After the early and late reflections have been defined, the following settings affect the entire reverb signal:

Wet and Dry: These control the mix between the processed reverb signal (Wet) and original unprocessed signal (Dry).

Width: Controls the stereo spread of the reverb signal.

Solo Reverb Signal: This check box lets you solo just the reverb signal.

Low and High Frequency Cutoff filters

You can control the bandwidth of the reverberated signal using the low and high frequency cutoffs. On the spectrum at the top of the module there are two nodes that create a curve that corresponds to these cutoffs. You can drag the nodes to the left or right to control the bandwidth of the reverb.

Reverb High and Low Cutoffs

Mini-Spectrum Window

The window at the top of the module defaults to a display of the signal spectrum which also features the Low and High frequency Cutoff filters.  However, with a selection on the left it may also display the Reverb Character view. 

Reverb Character view displays a graph that illustrates the character of the reverb signal over time given the settings you have selected.  This display can help you visualize how different settings affect the overall character of the reverb signal.


 Crossmix: Adjusts the amount of stereo spread between the left and right channels’ reverb signals.


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 and Reverb Character view have designated colors. Mid mode is presented as orange, and Side mode is presented as light blue.

Example using Mid-Side Processing with Mastering Reverb

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. When using the Mastering Reverb this allows you to tailor the reverb to more accurately depict your desired soundstage. For example, you can add both space and ambience to your mix by applying the reverb only to the sides of your soundstage.

To do this, begin by enabling the Side channel (light blue). Select the frequency bands for the instrument(s) that you want to apply the reverb to. Finally adjust your wet/dry mix to taste. Using Bypass in the Reverb module, try switching back and forth to hear the difference in your mix.

In other cases, you may actually use this feature to reduce the amount of reverb in the Mid channel to make the lead components sound more clear.

 Component Reverb Plug-in

If you are using Ozone 5 Advanced you will also have the ability to instantiate Ozone 5's Reverb 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.
