Features – Paragraphic EQ
Ozone includes a paragraphic equalizer that combines 6 bands of adjustable notch filters and low/high shelf filters. A Matching EQ mode allow you to capture spectrum snapshots of reference mixes then automatically adjust your project´s EQ with that spectral curve. Ozone 4 adds powerful Mid/Side processing letting you EQ the center of the stereo image separately from its edges.
Choose from analog modeled EQ with "soft saturation" modeling or digital linear phase filtering with up to 16,000 bands of precision.
Compare your mixes with a powerful spectrum analyzer that offers real time and average modes, critical or third octave bands and snapshots.
Use spectrum snapshots of recordings to create "automatic" EQ curves.
Mid/Side mode provides independent, superimposed EQ curves for center and edges of stereo image.
Easily select multiple nodes and drag to adjust their position and relative properties.
Features – Multiband Harmonic Exciter
Ozone´s Multiband Harmonic Exciter is a powerful tool for adding analog character to your masters. With a selection of Harmonic Exiter modes, you can easily add tube or tape saturation, accentuate even harmonics, and add punch or sparkle to your project. Multiband and mid/side modes give you a huge range of sonic possibilities.
Choose from retro, tape, tube or warm exciter modes, all of which offer their own unique saturation characteristics
Multiband operation lets you add different amounts of excitation to different frequency ranges
Ozone 4 adds powerful mid/side processing—add punch to the center of your mix, add sparkle to the edges, and much more
Unique multiband time offset controls for tightening and adding "attack" to bass and kick.
Features – IRC Loudness Maximizer
Ozone´s IRC Loudness Maximizer is essential for giving your recordings professional loudness and fullness. This powerful tool allows you to keep your master from clipping while dramatically lifting the perceived overall audio level. Ozone´s proprietary IRC (Intelligent Release Control) technology lets you get the loudness you want without introducing pumping and other unwanted limiting side effects.
Intelligent Release Control technology for transparent limiting
Predictive limiting of "inter-sample clipping" to keep true analog levels in check
New "Intelligent II" mode provides exceptional handling of transients without pumping artifacts
Adjustable threshold, margin, release and character controls
Visual feedback provided through gain reduction meters and loudness histogram.
Features – Multband Dynamics One of most powerful tools in Ozone is the Multiband Dynamics module, which incorporates compression, limiting, expansion and gating. Finely tune the dynamics of your mixes with independent control over up to four frequency bands. And now, with multiband mid/side processing, you have unprecedented control over dynamics in the center and edges of your stereo mix.
Up to 4 bands of limiting, compression, gating and expansion
Analog modeled, linear phase, and new hybrid crossover filters with adjustable bandwidth and Q
"Learn" mode automatically sets crossover frequencies based on incoming audio
Gain reduction meters, level histogram and spectrum analyzer for visual feedback
Real time visualization of the dynamics within each band, including gain reduction meters, level histograms and X-Y compression curves
Controls for comparing "gain when bypassed," offsetting overall band gain, bypass and solo for each individual band
Features – Multiband Stereo Imaging
Ozone allows you precisely adjust stereo width and imaging for your master using a Multiband Stereo Imaging module. As with the other multiband modules in Ozone (Dynamics and Harmonic Exciter) the module works with up to four frequency bands, letting you have independent control over stereo width by frequency. Integrated Vectorscope and Correlation Meter give you essential visual feedback for the mastering process.
Up to 4 bands of stereo width control
Visualize the stereo image with a powerful phase/channel meter display that highlights imaging, phase and potential canceling problems
Apply multiband channel delay controls for adjusting the perceived location of the stereo field or correcting tape azimuth errors
Includes options for mono, phase flip and channel reverse.
Features – Mastering Reverb
Ozone includes a professional 64-bit reverb module that can add a consistent sense of depth and space to a mix. 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. Ozone 4 adds mid/side processing to the Mastering Reverb module, allowing you to add ambience to the center and edges of your master separately.
Selectable plate or room modeling algorithms for "studio" or "acoustic" ambience.
Control room size, pre-delay, width, frequency cutoff and more
Special controls to solo the wet signal, adjust the frequency response and monitor the width and phase of the reverb signal
Mid/side processing lets you "dry out" the center of your mix while adding space to the edges, and much more.
Features – Dither
Ozone provides the finest dither algorithms available, allowing you to effectively convert and dither to 24, 20, 16, 12 or 8 bits. This is useful for mastering a track for CD (16 bit) from a 24 bit source, for example.
Ozone includes our proprietary MBIT+ dither algorithm that reduces quantization distortion with minimal perceived noise. This algorithm is a very smooth, quiet and almost "analog sounding" technology.
Choose from three types of noise shaped dither algorithms
Integrated DC offset filtering, auto-blanking and dither harmonic suppression for dynamic and transparent conversions
Unique set of bit scopes and DC level meters provide a complete view of the digital bitstream and conversion process.
Features – Preset Manager ad MacroPresets
Ozone´s preset manager gives you over 140 professionally-designed starting points for mastering your projects. In addition, new MacroPresets link controls within Ozone to MacroFaders, making it easy to shape a preset to fit your project, without even leaving the Preset Manager. Adjust simple controls with names like "Ambience," "Sparkle," and "Bass" which automatically adjust modules within Ozone to fine-tune your sound.
Advanced users will appreciate the ability to create presets that utilize all of Ozone´s modules and routing capabilities for instant recall of useful configurations. Not to mention you group your favorite Ozone controls to your own MacroFaders.
Features – Mid/Side Processing Mid/Side processing has been a trade secret of many mastering engineers for years. Ozone 4 makes this powerful approach to processing audio more accessible than ever before.
With mid/side mode enabled, Ozone converts the stereo information coming into the plug-in into mid and side signals, letting you work independently with the center of the stereo image or the edges. The result? You can surgically EQ the mud out of hard-panned guitars while preserving the vocal and kick drum in the center of your mix. You can add excitation or maybe a touch of room ambience to just the edges, and much more.
Ozone´s Paragraphic Equalizer, Multiband Harmonic Exciter, Multiband Dynamics and Mastering Reverb modules all incorporate mid/side modes. Color coding allows you to easily see mid and side settings superimposed. Ozone´s meters can also be used in mid/side mode.
Features – Exclusives Ozone is full of features designed to give you the best user experience possible. Whether you´re new to mastering or a professional engineer, you´ll appreciate the exclusive touches that set Ozone apart from other plug-ins...
User-Definable Routing – Ozone´s mastering modules are set to a logical processing order by default, but what if you want to create your own custom signal path? Simply open up Ozone´s Filter Graph and you can drag and drop modules to re-order them. No patch cables needed!
Undo history and A/B Tools – Have you ever wished you could undo the EQ changes you´ve made in a plug-in, only to find that your host program can´t Undo these changes? This is a common problem, and one Ozone 4 solves by including a comprehensive, built-in Undo History. Simply step back through your list of actions. You can even set A/B points in the history, so you can decide whether the settings you had a half hour ago sound better or worse than your current settings.
Metering and Visual Feedback – Some plug-ins present you with a huge array of knobs, and very little useful visual feedback. Ozone 4 is designed to give you vital visual information at every step of the mastering process. From phase and correlation meters for analyzing stereo imaging, to histograms and dynamics meters that help you see the effect of dynamics processing, to forward thinking K-System input and output metering, Ozone gives you a wealth of visual information.
