iZotope – Ozone 3.15 (VST, DX, AS, RTAS, HTDM) [WIN x86]


Year of issue: 2008
Version: v3.15
Developer: IZotope
Tabletka: Present

Ozone is a 64-bit mastering system from the American company iZotope, which includes seven mastering processors in one plug-in. Ozone contains tools for each stage of mastering (pre-mastering): equalization, multiband dynamics processing, adding harmonics, stereo panning, adding reverb, limiting and bit reduction. All Ozone components are designed to work together to create the ultimate professional master recording. The module is available in Pro Tools (RTAS / AudioSuite / HTDM), VST, MAS, Audio Unit and DirectX formats for Windows operating systems (XP, x64, Vista) and MacOS X 10.3.9 and higher (in Universal Binary format)
You can get started using Ozone with the presets (presets), which are good starting points for a variety of mastering situations. However, the Ozone feature is great flexibility, allowing users to customize each module individually, as well as change the order of modules in the overall processing chain. This makes Ozone the right tool for both novice mastering professionals and seasoned professionals alike.

Paragraphic equalizer
The Paragraphic Equalizer in Ozone provides six bands of customizable filters, in which parameters such as frequency response shape, Q factor, center frequency and gain are adjusted, it also includes a functional spectrum analyzer and a “matching” equalizer.
The Paragraphic Equalizer can operate in three modes. “Analog” mode simulates the characteristics of analog equalizers, bringing in the musical, non-linear qualities of traditional studio equipment. “Digital” mode uses filters with linear phase and frequency resolution up to 8000 bands for accurate and transparent signal processing without phase distortion. Ozone’s “matching” equalizer mode allows you to give a sound recording the frequency balance of another fragment (for example, a “reference” mix) or to match the frequency balance of tracks on a disc.
Spectrum analyzer Ozone can work both in real time with adjustable speed characteristics, and in the data averaging mode. This allows you to instantly see the effect of the equalizer on the signal spectrum, as well as evaluate its effect on the overall frequency balance of the entire composition. In addition to this, the frequency response fingerprint tool allows you to save and display the signal spectrum separately for later comparison or matching of spectra. The spectrum analyzer mode can be selected between FFT, one-third octave and “psychoacoustic”, which displays the energy in the critical hearing bands.

Multiband exciter
Ozone includes a multi-band exciter providing up to four bands of tunable harmonic saturation. It can be used to add energy and brightness to an entire mix or to specific frequency ranges. Algorithms for adding harmonics can simulate both tube saturation and tape overload.
Frequency bands in this and other Ozone multiband modules can be adjusted by choosing an “analog” (non-linear phase) or “digital” crossover (with linear phase, fine recovery, and variable Q) with configurable cutoff frequencies and a selectable number of bands. The solo and mute functions can be used to tune each frequency band.

Multiband dynamics processing
The multi-band dynamics processing section allows you to focus on individual frequency regions of the mix and selectively control their dynamics using the compressor, limiter, gate and expander. In each of the four bands, parameters such as threshold, compression ratio, gain, attack and release times can be independently controlled. Each band has a suppression level indicator, a signal level histogram and a visualization of the transfer function.

Multiband stereo corrector
This module allows you to narrow or widen the stereo panorama independently in each frequency zone or introduce a delay in an arbitrary frequency range. To visualize the effect, there is a goniometer and a correlometer that allow detecting imbalances in the stereo image and antiphase. Mono switches are available for checking mono compatibility, as well as left and right channel inversion.

Mastering Reverb
Ozone includes a reverb module that allows you to match the spatial picture of the tracks on the disc. Its task is to give the final shine to the entire mix, while maintaining the character of the space formed by the reverbs on the individual tracks.
The user is provided with a choice of plate and room algorithms for synthetic and convolutional reverb. In both algorithms, you can adjust the room size, pre-delay, stereo width and damping of low and high frequencies. The goniometer and stereocorrelometer allow evaluating the effect of reverberation on the width of the stereo panorama.

Maximizer (mastering limiter) OzoneUses iZotope IRC (Intelligent Release Control) technology that dynamically changes the release time of the limiter to achieve greater volume without degradation. The IRC distortion reduction algorithm reduces attack release time to maintain signal velocity and increases release time when limiting of smooth fragments is required.
The IRC algorithm is designed to be universal for all types of audio material. Adjustment of the algorithm (in addition to the limiting threshold and the “ceiling” of the gain) is carried out by the Character knob, which determines the aggressiveness of the limiter operation. The user can set the limiter to be more aggressive to achieve higher levels and bring the limiting closer to soft clipping, or can set the limiter to more transparency. Suppression level meter and signal level histogram help you to set the correct limiter threshold.

Dithering and bit reduction
The maximizer module also contains a dither section, which provides many options for reducing the bit depth. Ozone allows you to dither and noise shaping down to 24, 20, 16, 12 or 8 bits. There is also a DC offset filter in the dither section.
Ozone uses the original MBIT + dithering algorithm (the previous version of which is known as MegaBitMax or ExtraBit) to eliminate quantization distortion and minimize dithering noise. The noise added by the MBIT + algorithm has a special psychoacoustically optimized spectrum that reduces its audibility. This allows for completely transparent bit reduction even for high dynamic range material.
The dither section includes an indicator of the file width and an indicator of the level of the constant component of the file.
Features of working with Ozone
In addition to the seven mastering processors, Ozone includes several unique features that make the program more convenient to use.
The user is given the option of unlimited undo (undo) with a list of parameter modification history (log). This allows you to revise the settings at any time or compare the sound with different ready-made settings.
In addition to mouse controls, Ozone has many hotkeys and supports the mouse wheel. For example, the combination “Alt plus click on an equalizer band” turns on the solo mode for that band.
The integrated preset manager allows you to sort your presets by name or by frequency. Users can also add comments and notes to presets to make them easier to find.
Some Ozone algorithms can introduce latency (delay) into the signal. Many parent applications (host) allow you to automatically compensate for this delay. For applications that do not have this capability, Ozone provides an accurate latency value so that manual compensation can be made if necessary.
Ozone users include the following names: Just Blaze (producer Jay-Z, Snoop Dogg, Usher), Atticus Ross (producer Nine Inch Nails, Korn), Kerry Livgren (producer and performer Kansas), Paul Wertico (producer Pat Metheney group, seven-time Grammy recipient).
