Welcome to article 2 from my eleventh text, All About Equalization. I've known for decades that the subject of EQ was really the most important aspect of mixing quality, and therefore it would take a complete text to fully explain the subject. As students of the Recording Institute of Detroit you get a chance to read it as I am writing It. Initially it will be in the form of a series of articles in my DSP column, and this second article is entitled, "How and When to Adjust Bandwidth (Pt.3)."

It would be a good idea to review the basics before reading articles in this series. The linked module lesson will also give you an opportunity to take a test to check your comprehension.  Use this link to review a basic article "An Equalization Primer"

Demos of the EQ with different bandwidths are included in the article
