Plugin Boutique has published a tutorial and feature review of the smart:EQ 2 intelligent equalizer effect plugin by Sonible.
Smart:EQ 2 by Sonible makes high-resolution EQ curves by itself by analyzing any incoming audio. You can help it along by using built-in profiles or making your own. You can also use a regular EQ to modify the Smart EQ as well.
There are a number of great features on top of these things, like the Spectrum Analyzer, the Mid/Side processing capabilities on a per-filter node basis, and more.
