50 Years of Parametric EQ

For the past 50 years, parametric equalization has been widely used in many applications of audio engineering. In those 50 years, there have been multiple attempts to bring parametric EQ to the wider consumer market, with none meeting genuine success. We consider the issues facing the audio engineer and how parametric and subband (graphic or crossover-based) EQs each define an application archetype, and where in the audio production process the archetype provides a closer fit to the engineer's focus. We propose that, while both EQ paradigms are capable of solving the same problems, the graphic/crossover EQ is a better fit from an objective viewpoint (that of the intended audience), and parametric EQ is a better fit from a subjective viewpoint (that of the sources recorded and further rendered in the studio).
