iZotope Music Production Suite 7

There’s some really useful tools that from part of this package. The Ozone mastering software is probably my favourite- gives some really effective results when left to its own devices but also allows plenty of personal changes to be made.
All the other elements work well and if you’re a guitarist the Pro Rig 7.software is particularly comprehensive.
It’s not a cheap package especially if bought at full price but it is definitely full of useful software to complement or replace functions in your DAW.
