TRACT System Calibration

PA measurement, system calibration and SPL monitoring in one complete suite

Meet the New TRACT System Calibration:
Measure, Calibrate and Monitor Your PA

TRACT System Calibration is now a complete system-tuning toolkit, with three plugins working together to help you measure, calibrate and monitor your PA. The package now includes the new TRACT Measure and SPL Meter, alongside the original TRACT System Calibration plugin.

With the new TRACT Measure, you can measure your PA directly inside eMotion LV1, SuperRack Performer or SuperRack SoundGrid—no external measurement software or second computer required. Capture your system’s frequency response and delay, and send the measurement directly to TRACT System Calibration, which creates corrective EQ and time-alignment settings. (The TRACT System Calibration correction plugin also still works perfectly with Smaart®, giving you two alternative ways to feed measurements into the TRACT correction workflow.)

Once your system is tuned, the new SPL Meter lets you keep an eye on sound pressure levels throughout the show, directly from your Waves live host. Together, the three plugins give you a streamlined workflow from initial PA measurement and calibration to ongoing SPL monitoring.

An Essential Tool for Live Sound

TRACT Measure: Measure Your PA Directly in Your Waves Live Host
Insert TRACT Measure on a mono channel in LV1 or SuperRack, connect your measurement mic, load your mic calibration file, and capture the transfer function and delay in one pink-noise pass, using Auto or Manual mode. Send each capture directly to TRACT System Calibration, and combine multiple mic positions into one correction curve. Current, Last and Delta readouts provide exact offsets for time-aligning front fills and delay towers.
TRACT System Calibration: Turn Measurements into a Better-Tuned System
TRACT System Calibration turns measurements from TRACT Measure—or Smaart®—into practical system corrections. Automatically generate corrective EQ, customize the resulting curve, and time-align different parts of the PA. Whether you measure directly with TRACT Measure or use Smaart, your measurements feed into the same TRACT calibration workflow. TRACT System Calibration continues to support measurements from Smaart^®, including Spectrograph and phase-alignment analysis capabilities not currently covered by TRACT Measure.
SPL Meter: Monitor Levels Throughout the Show
Once your system is calibrated, the new SPL Meter helps you monitor sound pressure levels directly from your Waves live host. View current and maximum SPL, choose A- or C-weighting, and set a threshold to warn you when levels get too high. You can also log SPL measurements and export them to CSV for documentation and post-show review.
Beyond “Sweet Spot” to “Sweet Area”
Unlike room tuning systems that create a single “sweet spot,” TRACT can capture up to 8 response snapshots, and then merge them into a single correction curve that compensates for sound issues over the widest possible area.
Full integration with Smaart
TRACT integrates with Rational Acoustics’ Smaart (Sound Measurement Acoustical Analysis Real Time) software v9 including Suite, RT, LE (purchased separately).
Correct Room EQ
TRACT helps wayward audio by creating a corrective FIR EQ curve. Choose a minimal-phase curve for lowest latency and low phase distortion, or a linear-phase curve for perfect phase coherence.
Customize the Curve
Supplement the FIR curve with up to 8 bands of IIR EQ filters that offer a variety of shapes—bell, low/high shelves, flat-tops, tilt EQ with variable-frequency pivot point, Butterworth and Linkwitz-Riley curves, and more.
Sub Zoom for Maximum Low Frequency Impact
To reduce low-frequency muddiness and lack of definition, engage the sub zoom function. This lets you take a closer look at the low frequencies while phase-aligning subs for maximum low-frequency impact.
