Ozone isn’t just for mastering anymore
Ozone was designed for mastering but there are lots of possibilities for how Ozone can help out in music production.
Ozone 7 Features
Ozone’s highly regarded mastering limiter features a new IRC IV algorithm that uses spectral shaping technology, an innovative new way of processing audio. With IRC IV, you can achieve professional loudness and fullness without the limiter needing to work as hard. Get more transparent limiting than ever before with less pumping at higher volumes — ideal for times when you need to tame the kick drum peaks without causing vocals to pump, keep the subtle snap of a snare rimshot in a country single, or give a club track incredible impact. Prevent your master from clipping while dramatically lifting the perceived overall audio level, for more loudness without sacrificing crisp detail.
- Experience transparent limiting with multiple modes of the IRC™ (Intelligent Release Control) Limiter technology, including the new IRC IV.
- Preserve rhythmic detail while maximizing loudness with Transient Emphasis, which adds smart emphasis to transients.
- Unlink stereo channels to process left and right separately with the Stereo Unlink Control.
- Get visual feedback that informs your limiting with the Gain Reduction Trace meter’s scrolling waveform display.
- Plus: The "Tube" mode introduced in Ozone 6.1 has become the new Vintage Limiter module. And don't worry, it's backwards compatible!
Now in both the standard version of Ozone and Ozone Advanced, the Dynamic EQ module lives and breathes with your music. Get finer control over your sound with the precision of an equalizer and the musical ballistics of a compressor integrated into one processor. With an intuitive workflow and clearer visual feedback, Dynamic EQ is a valuable mastering tool that excels where traditional EQs and compressors fail.
- Choose from five filter shapes including Baxandall Treble, Baxandall Bass, Proportional Q, Band Shelf, and Peak Bell.
- Toggle between analog and digital modes for minimum or linear-phase processing across six independent bands.
- Access targeted dynamic equalization with Mid/Side and Left/Right processing modes.
- Intelligently adjust Attack/Release times automatically across the frequency spectrum with Auto-Scale mode.
- Dynamic nodes show the direction of your adjustments, to make it clear whether you’re expanding or cutting.
Vintage Limiter takes the "Tube" mode that we introduced to the Maximizer in Ozone 6.1 and expands it out to its own module and adds both a faster and slower setting. Vintage Limiter Glue a mix together and add character with the Vintage Limiter’s analog-sounding final-stage limiting. Retain the ease and precision of digital maximizing while bringing a natural feel to harsh and digital-sounding masters. Get the silkiness, body, and nostalgic vibe of classic recordings.
- Inspired by the Fairchild 670 hardware limiter, famous for its silky smooth compression.
- Fine-tune the Vintage Limiter’s response to perfectly fit your source material with the Character control.
- Get visual feedback to inform your limiting with the Gain Reduction Trace meter’s scrolling waveform display.
- Backwards-compatible with Ozone 6.1 presets that made use of the "Tube" mode in the Maximizer.
Ozone's Preset Manager gives you professionally designed starting points for mastering your projects. Power users will appreciate the ability to create presets that utilize all of Ozone's modules and routing capabilities for instant recall of useful configurations and a customized blend of analog and modern processing. Ozone 7 Advanced comes with additional presets that incorporate Advanced-only modules in the signal chain. Plus, the Greg Calbi Mastering Presets for Ozone now come as part of your product installation.
- Easily load and save settings for individual modules without affecting the settings of other modules.
- Streamline your decision-making process with outcome-oriented preset descriptions.
Easily fine-tune the dynamics of your mixes with independent control for up to four frequency bands, each with separate limiting, compressing, and expanding. The interactive Threshold control allows you to set threshold points for the Limiter and Compressor stages without taking your eyes off of the gain reduction meter, which provides extra feedback while making your detailed dynamics tweaks.
- Intelligently automate the difficult task of finding the right release times with Adaptive Release mode.
- Automatically set crossover frequencies based on incoming audio with Learn mode.
- Adjust the dynamics of the center of your mix independently of the sides of your mix with Mid/Side Processing mode.
- Find the perfect compressor settings with the Gain Reduction Trace view, which plots the gain reduction of all dynamics bands on top of a scrolling waveform, and get further visualization with the Dynamic Transfer Curve and spectrum analyzer.
- Add a variable slope high-pass or API Thrust-like Tilt filter for reducing pumping with the Detection Circuit Filter.
Specify the file format for export from a variety of compressed and uncompressed popular formats like MP3, WAV, AIF, and AAC. Eliminate the need for a separate converter and export your digital formats directly from Ozone.

Equalizer and Post Equalizer
Ozone includes two equalizers that combine eight bands of adjustable filters with a variety of filter shapes to choose from. Use the first Equalizer for initial shaping of your master, then take advantage of Ozone's Post Equalizer for even more shaping later on in your signal chain. The Analog-Matched EQ curves preserve analog behavior at high frequencies, giving Ozone authentic analog frequency response.
