German music website Amazona.de posted an in-depth test of iZotope's Ozone 7 (translated):
"iZotope Ozone 7 incorporates proven features and adds analog inspired vintage modules. Those looking for an all-in-one mastering suite can not look away from Ozone. Those who want to use them as individual plug-ins as individual Mastering modules should upgrade to the advanced version. Owners of previous versions can upgrade Ozone for a discounted price. Moving from Ozone 5 or older is worthwhile in any case."
