The iZotope Ozone 4 is a VST-based mastering suite that contains all the effects and plugins necessary for basic, home-studio mastering. It has six different sections, including paragraphic eq, mastering reverb, multi band harmonic exciter, multi band dynamics, loudness maximizer, and multi band stereo imaging. If you've never ventured into mastering before, some of these processes may seem familiar, but others can be a bit complicated. No matter, iZotope comes with plenty of presets for a variety of genres, and they are great starting points for your mastering needs.


I find myself using the loudness maximizer the most, which is the main effect that pushes the volume of the audio track as loud as possible. This is what most people think of when it comes to mastering, although there are other elements as well. But tonally, you can always adjust things in the recording mix, but the loudness maximizer is always the biggest missing piece that turns a recorded piece into a finished one. Many companies offer loudness maximizers, but the key is finding one with a great transparent algorithm, which can maximize the volume and reduce the audible artifacts. iZotope Ozone comes with multiple algorithms for different genres, from smooth to fast responses, and they all sound pretty good, as long as you don't push it too far. You can also use the multi band compressor to help level out the sound, which reduces the pressure on the maximizer/limiter.

When I do quick song releases to show my friends, I usually just run it through the loudness maximizer, just until the limiter starts to kick in slightly, and it gives me a full-volume release that is void of any limiting artifacts, and it is quick and easy to do. That is one of the reasons I really like this software: it's easy to quickly dial in anything.


Overall, I would recommend this product to any home studio that is in need for an in-house mastering solution. Be sure to try it out!
