Evouyn

Evouyn is a VST plugin that helps you set the low end in mastering situations. It measures the correlation between frequencies in the spectrum and warns you if the amount of low end exceeds what’s known to sound good.

The idea of the program came from the fact that many mixes sent for mastering either lack or have a crazy amount of low end, in most cases because of poor monitoring and/or the lack of proper acoustic treatment.
