LoudMax

The only limiter/maximizer you need. Dead simple, and helps you intuitively understand limiting and compression in general, whereas other more complex compressor plugins can leave you not understanding what exactly you're doing for years. No fuss with installation or activation.

The only thing you need to know is that it make quieter things louder than already loud things, and all without introducing clipping. A very desirable trait, since sometimes we want quieter things more audible in an overall mix, but we want to ensure that we're not distorting. Which is great not only for music but also streaming/podcasts. This of course lowers (or tightens) the dynamic range, and increases any pronounced noise floor. So it should be used sparingly if you wish to preserve dynamic range of say, a piano.
