Overview

Ozone contains a comprehensive user settings section that allows you to configure various settings for the program.

General Options

BUFFER SIZE

The Buffer Size Viewer dialog lets you inspect the buffer sizes that your host uses. If you are using Ozone at low latencies, you may experience unusually high CPU usage. Ozone allows you to tweak several buffer sizes in order to optimize CPU usage for your host application settings. Some host applications make it very easy to see what your buffer sizes are, but it can be more difficult to determine in others. For that reason, Ozone provides this dialog to let you find out exactly what buffer sizes are being sent to the plug-in. To use this dialog, simply launch it by clicking the View Buffers button on the General tab of the Options screen. Then use the following controls:

NAME DESCRIPTION
Captured Buffer Sizes This list-box shows the buffers you have captured thus far. The number on the left is the input buffer size, and the number on the right is the output buffer size.
Start/Stop Push “Start” to begin capturing buffer sizes. Now each time a buffer is sent to the plug-in, it will be added to the list of captured buffer sizes for you to see. Push “Stop” to stop capturing buffer sizes.
Clear Clears the list of captured buffer sizes.
Copy Copies the list of gathered buffer sizes to the Windows/OS X clipboard, useful for pasting into a support e-mail if necessary. See Buffer Sizes for more info.

ENABLE METERS

Although each module’s meter has its own options, this option allows you to quickly turn on/off all meters.

SHOW TOOLTIPS

When enabled this allows informational notes to appear when the cursor/pointer is hovering on top of the features’ controls.

FRAME RATE LIMITER

Allows you to set the speed (frames per second) that Ozone should use to display and update meters. In most cases the default will provide smooth displays while still allowing adequate processing time for audio.

If your PC hardware allows it, you can increase the frame rate for smoother animation. On the other hand, if you are running Ozone on slower hardware or notice graphics performance problems in your host application, you can set the FPS value lower to limit the amount of CPU Ozone uses.

DIM CONTROLS WHEN BYPASSED

When this option is enabled, each module’s controls will be dimmed when the module is bypassed. This feature helps to remind you when a module is bypassed, so that you don’t make adjustments to a bypassed module unintentionally.

MODULE PRESET MANAGER CHANGES WITH MODULE SELECTION

When this option is enabled, the Module Preset manager will display the presets for the currently selected module. If disabled, the currently displayed Module Preset manager will not change when different modules are clicked on.

ENABLE ANALYTICS

Check this box to allow Ozone to upload data on your usage patterns of the application to iZotope’s servers. This info is completely anonymous, and allows us to better understand how users use the application, in order to provide the best updates possible in the future.

HISTORY DEPTH

Lets you set how many levels or steps are remembered in the Undo History window.

KEYBOARD SUPPORT

Available options include:

  • Full (full keyboard support)
  • Minimal (only TAB, arrow keys, and ENTER)
  • None (Keyboard shortcuts turned off )

The keyboard support option must be set to “full” for all keyboard shortcuts to be available.

AUTH & UPDATES

CHECK FOR UPDATES

Selects the frequency with which Ozone 8 automatically checks for available updates.

  • You may choose between:
    • Daily
    • Weekly
    • Monthly
    • Never

CHECK NOW

Instantly checks if your version of Ozone is currently up to date.

AUTHORIZE

Runs the authorization wizard, allowing you to authorize your copy of Ozone if you have not already done so.

MORE INFORMATION

Directs you to the iZotope Customer Care page about authorization.

Spectrum Options

The Spectrum options tab lets you control various properties for Ozone’s spectrum analyzer meters.

FILL SPECTRUM

Allows you to display the real-time spectrum as a solid graph as opposed to a line graph. This option can be used to differentiate the real-time spectrum from the peak hold spectrum.

SHOW PEAK HOLD

Toggles whether Ozone displays and holds the peaks of the spectrum.

SPECTRUM TYPE

Lets you select between four types of spectrums:

  • LINEAR: A continuous line connecting the calculated points of the spectrum.
  • 1⁄3 OCTAVE: Splits the spectrum into bars with a width of 1⁄3 of an octave. Although the spectrum is split into discrete bands, this option can provide excellent resolution at lower frequencies.
  • CRITICAL: Splits the spectrum into bands that correspond to how we hear, or more speci cally how we di erentiate between sounds of di erent frequencies. Each band represents sounds that are considered “similar” in frequency.
  • FULL OCTAVE: Splits the spectrum into bars with a width of one full octave. Window Size Controls the size of the spectrum analyzer, allowing you to optimize it for di erent sized monitors.

WINDOW

Selects a window type for the spectrum. In most cases the default window type will work well, but you can choose from a variety of window types. Each window type has different amplitude and frequency resolution characteristics.

PEAK HOLD TIME

You can click on Peak Hold Time to select between specific hold times in milliseconds or In nite, where the peak is held inde nitely. You can reset the peaks by clicking on the spectrum.

AVERAGE TIME

Averages the spectrum according to this setting. Higher average times can be useful for viewing the overall tonal balance of a mix, while shorter average times provide a more real-time display.

OVERLAP

Controls how often the spectrum updates. More overlap will cause the spectrum to update more frequently, at the expense of increased CPU usage.

EQ Options

SHOW SPECTRUM

Check this box to display a real-time spectrum analyzer signal underneath the Equalizer curve.

This can be very useful in showing the frequency balance of your mix and how it is changed as you apply equalization.

SHOW MUSICAL UNITS

When this setting is checked, it allows you to display frequency labels as notes (for example, A4) in addition to the conventional EQ measurement of Hz.

SHOW EXTRA CURVES

Click on this setting to display Phase Delay, Phase Response, and Group Delay

SOFT SATURATION

Checking this button allows the audio material, when boosted to the point of overloading, to saturate in a more forgiving, analog-type matter, as opposed to harsh, digital-style overloads.

BUFFER SIZE

Adjusts how large of a memory buffer, measured in samples, Ozone uses when applying equalization to the signal.

FREQUENCY RESOLUTION

Selects the minimum resolution, in Hz, the Equalizer can be adjusted in. * Choices include: * 3 Hz * 6 Hz * 12 Hz * 24 Hz * 48 Hz

FILTER SIZE

Adjusts the steepness of the filter setting used in the EQ module.

ALT-SOLO FILTER Q

Sets the bandwidth (Q) of the Alt-Solo Feature.

Imager Options

PREVENT ANTIPHASE

When checked, the Imager will automatically prevent any settings from being applied that would result in phase cancellation of the stereo signal, when summed to mono.

VECTORSCOPE DETECTION METHOD

Chooses which type of amplitude detection method is used by the Vectorscope. Choices include:

  • PEAK: When this option is enabled, Ozone’s detection circuit looks at peak levels of the incoming signal. In general this is useful when you’re trying to even out sudden peaks in your music.
  • RMS: When this option is enabled, Ozone looks at the average level of the incoming signal. RMS detection is useful when you’re trying to increase the overall volume level without changing the character of the sound.
  • ENVELOPE: Envelope mode behaves much like RMS mode, but with some key advantages. Unlike RMS, True Envelope mode produces even levels across all frequencies.

CROSSOVER TYPE

Selects between a digital-linear phase crossover, an analog crossover, and Ozone’s Hybrid crossover.

  • ANALOG crossover option provides a natural analog character.
  • DIGITAL crossover provides a more transparent sound.
  • HYBRID crossover is a perfect reconstruction IIR analog crossover designed to reduce phase distortion and frequency distortion found in other analog crossovers while maintaining precise crossover points and the warm characteristics of analog crossovers.

CROSSOVER BUFFER SIZE

Determines how large of a digital audio buffer is used in the Imager module crossovers.

CROSSOVER Q

When in Digital mode, you can manually set the bandwidth of the crossover points in the Imager module crossovers. A higher Q results in tighter crossovers, while a lower Q provides a more gradual transition from one band to the next.

I/O Options

ENABLE METERS

Check this setting to enable the meters in Ozone’s master I/O section. When unchecked, the meters will not appear.

SHOW PEAK HOLD

Check this setting to allow the master I/O meters to visually display a peak hold, whenever peaks occur in the loaded audio le.

DETECT TRUE PEAKS

By default the Input/Output meters will only indicate clipping which occurs within the digital domain. To accurately measure the signal that will result from digital to analog conversion, select Detect “True Peaks.”

Enable Legacy Auto Match Effective Gain Behavior

BEHAVIOR WHEN CHECKED:

When Ozone is on there are many modules such as the multiband dynamics and loudness maximizer that can affect the overall or perceived loudness of the mix. This makes it very hard to compare “Ozone on” to “Ozone bypassed.” The “Automatically Match Effective Gain When Bypassed” feature solves this problem. Ozone determines how much perceived gain is being added by all of the active Ozone modules and then automatically adds this amount of gain when Ozone is put into bypass mode. You can bypass Ozone, and the gain is automatically adjusted so that when you A/B Ozone on and off, the apparent volume is the same. This gain processing is the only processing that is applied when Ozone is bypassed, and it is of course only applied when Ozone is actually bypassed.

Note: In the plug-in version of Ozone, this may not work if you use the host application to bypass Ozone. If the host application reports that it is bypassed, it will work and the Bypass button in Ozone will automatically depress accordingly. If the host does not report that it is bypassed, Ozone doesn’t know and therefore cannot apply the “gain when bypassed.”

BEHAVIOR WHEN UNCHECKED:

Enabling Gain Match in the I/O section when this option is disabled will result in the output gain sliders auto-adjusting apparent output level to match the dry signal level. The output faders will turn blue when they are auto adjusting level. This is useful to A/B the effect of Ozone processing. Unlike the legacy auto gain behavior, we recommend turning Gain Match on and off as needed rather than keeping it enabled all the time. This behavior does affect the output of Ozone.

Meter Type

Ozone 8 allows the I/O meters to display peaks according to several different audio monitoring types, including:

RMS

RMS (Root Mean Square) is a software-based implementation of an analog-style level meter. Using different integration times, you can model popular VU or PPM meters. The RMS meter displays the average level calculated over a short window of time. The RMS meter readout will typically be lower than an equivalent PPM meter (Digital/Analog), since it is averaging peaks into the overall loudness.

PEAK

The Peak meter is a fast meter that measures instantaneous maximum sample value or peak analog waveform values, depending on the “detect inter-sample peaks” checkbox. If you are tracking the peaks for possible clipping, the Peak meter is appropriate.

RMS + PEAK

This is a combined RMS and Peak meter. This meter displays a lower bright bar representing the average level (RMS) and a higher dimmer bar representing peak level. There is also a moving line above the bar representing the most recent peak level or peak hold.

K-SYSTEM

Ozone 8 supports Bob Katz’s K-System metering with simultaneous peak and RMS displays.

MOMENTARY

This measurement is a calculation of loudness over the course of 400ms.

SHORT TERM

This measurement is a calculation of loudness over the course of 3 seconds.

INTEGRATED

This measurement is a calculation of loudness over the course of an indefinite period of time.

SCALE

This sets the range and scale of the I/O Meters.

  • dB (Linear): Decibel scale presented linearly from -60 dB to 0
  • dB (Non-linear): Full decibel scale (dBfs) presented non-linearly
  • BS.1771: Loudness scale recommended by the ITU that spans from -45 LUFS to -14.0 LUFS
  • EBU +9: Loudness scale recommended as a default by the EBU that spans from -41.0 LUFS to -14.0 LUFS
  • EBU +18: Loudness scale recommended for material with a wide Loudness Range by the EBU that spans from -59.0 LUFS to -5.0 LUFS.

Note: LUFS is Loudness Units Full Scale and 1 LUFS = 1 dB.

SOURCE

Selects the audio source feeding the meters. Choices include:

  • Stereo
  • Mid/Side

By default, the I/O meters will display the Stereo mix of your audio. However, when working with Mid/Side processing, it is often very helpful to have a clear meter indication of the overall Mid and Side levels individually. When the I/O meters are in Mid/Side mode, they will no longer display your signal in terms of Stereo Left and Right. Instead, on the left side of the meter will be the level of the entire Mid signal, and on the right will be the overall level of the side signal. The Left and Right Gain sliders will still control the Left and right Gain of your signal however. The Mid/Side meters will still adhere to the same Type and Scale settings defined in the I/O options menu.

PEAK HOLD TIME

Selects how many consecutive samples of audio must exceed digital full scale, before registering as a peak. Choices include:

  • 5
  • 250
  • 500
  • 1,000
  • 5,000
  • Infinite

INTEGRATION TIME

This setting lets you specify the integration time for the RMS calculation. In most RMS meters, the integration time is set to around 300 ms. * 10mms * 50ms * 300 ms (vu) * 1,475 ms * 2,650 ms * 3,825 ms * 5,000 ms

READOUT

Selects whether the peak hold section of the meters displays the current peak status (current) or instead displays the highest peak that has occurred in the audio file (max peak).
