iZotope Ozone 12

iZotope Ozone is the industry-standard all-in-one mastering suite. Since its introduction, it has been the most complete software solution for mastering, combining multiple processing modules with intelligent assistance and comprehensive metering.

Processing Modules

The module chain covers every stage of mastering. The Equalizer provides up to 8 bands of parametric or matching EQ with analog and digital modes. The Dynamics module offers multiband compression with up to four bands. The Exciter adds harmonic saturation across four independent bands with multiple saturation types (tube, tape, retro, warm). The Imager adjusts stereo width per frequency band. Vintage modules model classic hardware: Vintage EQ (Pultec-style), Vintage Compressor (optical/bus), and Vintage Limiter (tube).

Master Assistant

Master Assistant analyzes your track and generates a complete processing chain with suggested settings based on genre targets and optional reference track matching. It selects which modules to use, sets initial parameters, and provides a starting point that experienced engineers refine and beginners learn from. The assistant handles routine decisions — tonal balance, dynamic range, stereo width — so the engineer can focus on creative choices.

Maximizer and Metering

The Maximizer handles final limiting with multiple IRC (Intelligent Release Control) algorithms optimized for different material. True peak limiting ensures streaming platform compliance. The codec preview auditions how your master will sound after MP3, AAC, or Ogg encoding. Comprehensive metering includes loudness (LUFS), true peak, phase correlation, and spectral analysis — everything needed to deliver masters that translate across playback systems.

Who Is This For?

Ozone suits anyone handling mastering duties:

• Producers mastering their own tracks with guided assistance
• Mastering engineers wanting an integrated, efficient workflow
• Mix engineers delivering broadcast and streaming-ready masters
• Beginners learning mastering concepts through the Master Assistant
• Anyone needing loudness-compliant masters for Spotify, Apple Music, and YouTube

For purists preferring discrete analog-modeled processors, separate plugins offer alternatives. For comprehensive mastering in one package with modern workflow, Ozone is the standard.
