K-system

This article is about calibrated mastering. For automorphism, see Kolmogorov system. For the musician, see K-System.

The K-system is an audio level measuring technique proposed by mastering engineer Bob Katz in the paper "An integrated approach to Metering, Monitoring and Levelling".^[1] It proposes a studio monitor calibration system and a set of meter ballistics to help engineers produce consistent sounding music while preserving appropriate dynamic range.^[2]

The K-system dB scale.
