Cambridge, MA - Feb 11, 2009 - Izotope is shipping Ozone 4, its latest update to the company's software mastering suite. Izotope has also created an upgrade path for current customers and posted an unrestricted, free 10-day trial of the software.

Ozone 4 builds on the program's sound quality and mastering tools with new refinements.
