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!

Dynamic EQ

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.

Ozone 7 Dynamic EQ

NEW Vintage Limiter

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.

NEW Vintage Tape [Advanced Only]

The Vintage Tape module brings the distinctive richness and feel of tape saturation to your modern digital recordings with all the frequency coloration, distortion, and phase effects of tape. Take advantage of analog tone for masters that sound more musical with added dimension, fatness, and depth.

  • Get the deep, natural sound and punchy low-end response of analog tape with the convenience of a digital interface.
  • Inspired by the innovative Studer A810 tape machine, known for excellent frequency response even at the critical high and low frequency range limits.
  • Continuous Bias control allows for precise tuning of frequency and distortion response.
  • Mix in even harmonics for warmer saturation, or leave them out for more accurate tape emulation.

NEW Vintage Compressor [Advanced Only]

The Vintage Compressor module is a single-band feedback compressor for subtle warming and sweetening effects. Featuring program-dependent release times, the compressor tailors release shapes to adapt naturally to your music. Thicken the mid-range, tighten and round out the lows, let the top sparkle, and get authentic vintage character.

  • Program-dependent release times keep the compressor's processing transparent, for example: longer release times for vocals to reduce pumping and fast release times to keep drums sounding tight and natural.
  • Editable high-pass, mid-peak, and high-shelf sidechain filters let you mimic the nonlinear frequency response of vintage hardware compressors, or create unique compression effects not available in traditional hardware.
  • Automatic gain compensation provides automatic makeup gain, allowing you to easily compare your mix with and without dynamics processing applied.

NEW Vintage EQ [Advanced Only]

With the richness, musicality, and color of Pultec equalizers, Vintage EQ lets you brighten your master, smooth out heavy low end, and add body to your digital recordings. With discrete frequency value selections, you can bring a musical focus to your EQ approach. Use the boost and cut controls separately – but at the same time! – for a low-shelf that boosts first, then cuts, and then levels out to smoothly avoid making your mix sound “boomy.”

  • Add the richness, warmth, and color of analog equalization to your audio.
  • Models the qualities and experience of Pultec hardware equalizers for a unique, musical way to manage equalization.
  • Mid/Side and Left/Right processing modes give you unprecedented control over the stereo soundstage.
