Mastering Modules
Standard Module Controls
At the bottom of each of the modules is a navigation bar that includes a set of buttons and controls. The function of these controls is the same regardless of which module you are using.
Reset Button: Resets the control to its default value . For most mastering modules, this means setting the values of controls in the displayed module to zero or some "neutral" state.
History: Clicking on the History button brings up a window which shows a history of the operations that have been performed. You can undo a single operation or sequence of operations and assign setups to keyboard shortcuts for A/B/C listening comparisons.
Module Preset: Load and save presets for individual modules to mix and match different module’s settings to better address the specific needs of your mix. Launch each module's individual preset manager by clicking on the button to the right of the module's active LED.
Solo: Clicking the Solo button turns off (bypasses) all the mastering modules except the one currently displayed. This allows you to audition the effect of one module without hearing the effect of the others. If you change screens by selecting a different mastering module, the solo will be automatically turned off so that you can work immediately on the new screen and hear the effect (without worrying about whether a screen that isn't displayed is being solo'd).
Bypass: Clicking the Bypass button on the touchscreen turns off the processing within the currently displayed module. This allows you to compare the sound with or without the currently displayed module. Unlike the Solo button, if you change screens by selecting a different mastering module the bypass will still apply. This allows you to bypass more than one module.
Note: You can also bypass modules by clicking the Active light on the Ozone faceplate as shown below. You can solo a module by holding down the Alt key and clicking the Active light for the module you wish to solo. Graph: The Graph button reveals the order in which Ozone processes audio through the main modules. Here is the default order of signal processing through the main mastering modules:
• Equalizer
• Reverb
• Dynamics
• Harmonic Exciter
Ozone 5 Help Documentation
18
• Stereo Imaging
• Maximizer
Clicking on the Graph button also allows you to change the order of processing, and insert the meters at any point in the signal path. You could, for example, view the spectrum before the EQ, or the phase meter after the reverb but before the stereo widening. By default, the spectrum and phase meter are based on the final output signal (the readout is the signal after all processing). The processing order of the final output stage is fixed by design. You can learn more about this in the Ozone Mastering Guide. The final output stage is as follows:
1. Output level gain control
2. DC offset filter
3. Dithering
4. Output level gain meter Options: Opens the Options screen which lets you customize the behavior of meters and set other properties. (?): Opens the Help file to the specific page or topic that relates to the mastering module shown.
Slider Compare Feature: You can Shift+Click on any slider in Ozone to quickly A/B the changes that have been made to that slider. This works for all sliders on the touchscreen as well as the Module/Global Amount Sliders.
Global Amount Control
You can use the Global amount control in Ozone 5 to make quick changes across all Ozone modules with a single slider. Beyond just A/B-ing your mix, this control lets you intelligently dial in "more" or "less" Ozone processing across your recording. You can easily hear the overall effect of a more aggressive or more subtle approach to your entire mastering session.
Use the Global Amount slider to hear the effect of adding or removing the amount of Ozone processing that is currently being applied to your session. This feature is most effectively used at the end of your mastering session or after a specific preset has been selected.
When the Global Amount slider is set to 100% you are hearing the default settings for the currently loaded preset. As you lower/raise the Global Amount slider, you will see all of the active modules lower/raise as well. The range of the amount control is from 0% to 200% as shown. You can also double click on the slider to enter a numeric value.
0% - no effect applied
50% - (subtle) small amount of effect is applied

how to get the Highest Audio Quality in izotope

Ozone uses highly optimized audio signal processing to achieve the highest resolution and sound quality possible. All of the mastering modules in Ozone are specifically designed to work together. By carefully matching crossovers and other internal processing, Ozone eliminates phase and artifact problems encountered when chaining together separate plug-ins. In addition, the sound quality and characteristics of each of the mastering modules is tuned to complement the others, providing consistent and high quality results.
Ozone uses analog modeling to give each of the mastering modules a smooth natural sound. For example, the equalizer recreates the soft limiting exhibited by a vintage valve equalizer, while the harmonic exciter mimics the musically pleasing harmonic saturation of a vacuum tube component.
Whenever there was a choice of CPU vs. sound quality, we chose sound quality. There are easier (less CPU intensive) ways of doing some of the processing that Ozone does, but the sound quality can suffer. Since Ozone is meant to be used for mastering, you would typically only have one instance of Ozone running on the main bus of a session, or in a 2 track editor, which should allow you to utilize Ozone even on lower powered CPUs.
Powerful Audio and Visual Feedback
We wanted to provide visual feedback wherever possible. Your ears and your eyes can be a powerful combination when you're mastering, and each processing module is complemented with useful spectrums, phase meters, and level histograms. Each module also has switchable views that highlight different aspects of how your mix is affected throughout mastering.
We also wanted to make it easy to get audio feedback by providing extensive solo/bypass controls and histories with functions for A/B comparisons. The Alt-click function on the EQ is an example of this as well. Wherever possible, we wanted to give you new ways to really hear what you are doing.
Intuitive Design and Easy to Use
We tried to make Ozone as easy and intuitive as possible from including a complete set of mastering modules in a single plug-in system, to context sensitive help, to the little things like mouse wheel support. There is a lot of power in Ozone, but we think that in no time at all you'll be making the most of it and getting great results with ease. Whether you’re a seasoned professional or you’re simply ready to take your productions to the next level, Ozone is the complete solution you need. Your mix isn’t finished until you put it through Ozone.
This help file is a quick reference for basic Ozone functions and controls. We have written a separate Ozone Mastering Guide that provides tips and techniques for mastering with Ozone.
