It's standalone so there are no issues with hosts or the like. You simply open a file in it, select a preset, tweak it, and hit Process. Then you can do A/B testing.

I tried it on my own material and it really improved it, but then again I am not good at mastering.
The only problem I see with it is that since it's not realtime, I need to tweak, process, tweak, process etc until I'd be happy with the results.(However, I think this must be this way, as it probably looks at longer periods of time in the audio material.)
I am also not sure about the audio quality. Not that I think it sounds bad, it's just that I have never heard of Nammick before, so it makes little sense someone would code compressors, exciters etc and no one has ever heard of the dev (or discussed Blackbox 1 on KVR!).
Its controls are explained nicely here: https://nammick.com/blackbox/wiki
All in all, this could be the best thing since... I don't know - shoe laces? - but I just don't know yet, so I hope for more takers. The download is super easy to install - its just an exe file.
If it gets updated, I would also like more presets, like one for ballads and one for country for example. Now it's geared a lot towards EDM and the like genres.
