iZotope has announced version 4 of Ozone, their mastering suite. iZotope has updated and expanded Ozone’s processing algorithms and “optimized them for today’s low-latency DAW environments”.

New features includes a new Intelligent Loudness Maximizer, Perfect Reconstruction crossovers, mid/side processing for superior control over the sound stage, and a new True Envelope dynamics processing mode.

Key features:

From the iZotope press release:

• Integrated mastering system combining analog warmth and digital precision
• New Intelligent Loudness Maximizer mode provides full-sounding masters while handling transients with unprecedented
clarity
• New Perfect Reconstruction crossovers combine analog character with digital clarity
• New mid/side processing adds a whole new dimension of power to Ozone’s EQ, dynamics and harmonic exciter by
letting you process different parts of the soundstage separately
• True Envelope dynamics processing introduces a new alternative to traditional Peak and RMS-based dynamics processing
for exceptionally transparent compression, expansion and limiting
• Improved and enhanced preset system lets users adjust a few simple parameters to get amazing results
• Many more interface and ease-of-use additions

Ozone 4 will require Pro Tools 7 (RTAS/AudioSuite) if you’re using Pro Tools, but will also be released in VST, MAS, Audio Units and DirectX versions.

Ozone 4 will ship in January of 2009 for $249 MSRP.
