About IEM EQ Guide
IEM EQ Guide is a long, free-standing reference on practical equalizer (EQ) use for in-ear monitors (IEMs) and audio reproduction. It is aimed at most people, from beginners to experienced listeners. It summarizes some basic theory, though it helps to already understand the hearing system, audio, and waves.
The guide is organized into seven main sections: Audio & EQ Basics, How to EQ, Case Studies, Rigs, Curves, & Targets (covering metrology and preference testing), Measurement Databases, Myths & Misconceptions, and Additional Tools. It also includes a daily changelog and an FAQ/Contact page. Sections can be read in any order. A shorter, condensed introduction is available through the Equalizer tab of squig.link databases.
