The following review written by one of the Software Informer contributors applies to version 3.0
The iZotope Ozone 3.0 program is a complete 64 bit analog modeled mastering suite of all the tools necessary to master commercial sound and produce higher quality audio.
Available for formats Pro Tools 6.4+ (RTAS Audio Suite/HTM), VST, MAS, Audio Unit, and DirectX, instead of a varied amount of plug-ins, users have the advantage of Ozone’s 7 plug-ins in one.
Users can master tracks in for 16 bit CDs from a 24 bit source, by converting and dithering to 24, 20, 16, 12, or 8 bits. The Dither module features include a proprietary MBIT and noise-shaped dither, and peak limiting and harmonic suspension. Ozone 3’s evolutionary MBIT+ dither algorithm reduces quantization distortion with minimal perceived noise, creating a smooth, quiet noise.
Practical Mast Modules full of features include Multiband Stereo Imaging enabling users to set widening and imaging. The Mastering Reverb module in this program is a high quality 64 bit module that is designed to add an even more professional element to final mixes by allowing users to use reverbs on individual tracks to give a sense of space. This module also features options for mono, phase flip and channel reverse. For tone balancing, Ozone 3 includes an analog modeled Paragraphic Equiliser module with 8 fully adjustable filter nodes for tone balance. Another important feature of this software is its Multiband Harmonic exciter which has been modeled on analog tube saturation providing a more natural sounding excitation. A Mastering Guide is provided as well as Video tutorials.
