MagicEQ is a mastering tool, based on a new equalization concept that can be resumed in 4 words: Statistically-Adaptative Automatic Equalization.
To use DUY MagicEQ, you should insert the plug-in, play your music and click on the LEARN button. This will begin a process of analising your music, which will result in an auto-equalization of your song. You can still modify many parameters after the EQ'ing has magically taken place.
