iZotope Mix & Master Bundle Advanc. CG

I think it is a seemingly useful tool. It can do a lot and is fairly powerful.
What I don't enjoy is the LUFS levels that are targeted. The Algorythm goes a bit crazy and you always have to dial back to have a bit less crushed sounding mixes.
Also Analyzing sound profiles etc, does not work the expected magic.
Nonetheless, the low-end focus, clarity feature, truepeak limiters and many more are all helpful in the last bit of the production.
It can help you make music sound louder and fuller and a bit more controlled.
What I personally miss is that it magically enhances things to sound more lively, like master tape emulations can handle it e.g.
That being said it depends on the type of music you are making and what you are after but all in all this will help you get your mixes to reasonable level.
