Tried it for 5 minutes. Really don't like the sound of it.
And I know it's free, but this is not a good plugin. From what I can tell there is only peak metering, no LUFS. Maybe I'm wrong and there's a setting I'm missing, but that's deal breaker for something called "mastering studio" that is a stand alone plugin that can't be put in a chain with a LUFS meter, phase meter, etc.
The dynamics / tone pages are on different tabs...for a standalone plugin that can be full-screened. When I fullscreen it there's like 8 buttons on one page, with 90% wasted space, and same on the other tab. Just put them on the same page ffs. If you're trying to coordinate between some macro tone and the compressor / limiter, you're going to have a bad time.
The limiter does NOT sound good. Neither does the saturation. Can't delta auditon on the de-esser. No loudness match on bypass. (!!) No dynamics reflected on meters. No mono switch, just 300hz mono maker. No autogain. Can't tell what they're target audience is here since Ozone 11 Elements pops up for free once in a while - and would be a significant improvement over this in every way imaginable.
This feels like one of those freebie apps that would come with Windows along with Minesweeper. Even for free, this feels like it would actually do more damage than good. Very disappointed in Brainworx / PA here.
