TRACT System Calibration.
Three plugins that measure and tune a live PA and log SPL.

Overview
Tune the PA, then watch levels.
TRACT System Calibration is a three-plugin suite for tuning a live PA, pairing the original calibration plugin with TRACT Measure and an SPL Meter. Measure captures the system's frequency response and delay inside eMotion LV1 or SuperRack, with no second computer, and hands them to the calibration plugin, which also accepts Smaart measurements. That plugin builds a corrective FIR curve that eight IIR bands can refine, time-aligns front fills to the mains and helps line subs up with the tops. The SPL Meter logs levels during the show.
