Foundations of Audio: EQ and Filters

In this installment of the Foundations of Audio series, author Brian Lee White shows producers and audio engineers how to properly apply equalization (EQ) and improve the sound of their mixes. The course covers the use of parametric and graphic EQs—and filters such as the high/low pass filters and shelf filters—in a variety of musical settings. These principles can be applied to any digital audio workstation platform, including Logic and Pro Tools, as well as analog workflows. Exercise files are included with the course.

Topics include:

* Measuring frequency and amplitude
* Understanding the relationship between frequency and pitch
* Working with EQ controls such as bandwidth (Q) and gain
* Using graphic EQ
* Understanding the shelving and high-pass and low-pass filters
* Creating focus with EQ
* Creating complementary EQ curves
* Performing frequency bracketing with filters
* Automating EQ
* Using frequency analyzers
* Using harmonic generators to excite frequency content
