Ozone 4 benefits from a cosmetic overhaul - the look is now futuristic and generally very pleasing to the eye - but most of the key controls remain in familiar places, which is a good thing if you are upgrading. Readers might, therefore, refer back to the original 2002 review ( /sos/apr02/articles/izotopeozone.asp) for the basics, and I'll focus here on some of the key improvements in this release. The general operation of the plug‑in and its core modules has remained very similar through Ozone's development. Izotope's flagship, all‑in‑one mastering suite was first reviewed by SOS back in the April 2002 issue, and version 4 was launched at the recent NAMM show with a list of new features and improvements.Īt its heart, Ozone 4 is still based around the six modules found in the original release: Paragraphic Equaliser, Mastering Reverb, Multi‑band Dynamics, Multi‑band Harmonic Exciter, Multi‑band Stereo Imaging and Loudness Maximiser.

Ozone 4's smart new look: note the module and global Amount sliders and the new Intelligent II mode for the Loudness Maximizer. Izotope's comprehensive suite of mastering tools continues to develop and mature, yet still offers excellent value for money.
