The Mastering EZmix Preset Pack from Toontrack comes with a wide variety of effect chains for the most common mastering needs and music genres. Whether you are working on a loud metal song, a mellow jazz tune, or a big house anthem, this pack has one-click settings to suit your requirements. This pack comes loaded with 50 different mastering presets. Mastering is the final audio processing step before a song is ready for distribution. In simple terms, mastering means you take your final mix and add various amounts of EQ, compression, and limiting to make it sound as good as possible whether you play it on a car stereo, a hi-fi system, or a compact mono radio. Please note that this requires the EZMix 2 Multi-Effect Mixing Tool.
