Waves TRCTSPL Tract SPL Meter Plugin for Live Mixing Hosts

The Waves TRCTSPL Tract SPL Meter is built for live sound engineers who need sound pressure level data visible inside their mixing environment without switching to an external application. It runs natively inside the eMotion LV1 software mixer and the SuperRack plugin host, keeping critical SPL information on screen during a show without adding a separate monitoring tool to the workflow.

A large SPL readout delivers an immediate read on current levels, while maximum-level hold tracks peak values across a set. A- and C-weighting options let engineers match the measurement curve to the application, whether that is a venue with strict noise ordinances requiring A-weighted dB(A) compliance checks or a production requiring flat broadband awareness. A user-defined threshold triggers a visual warning whenever levels exceed the set point, giving front-of-house and monitor engineers an at-a-glance alert without constant numerical attention.

Beyond real-time monitoring, the TRCTSPL supports continuous SPL logging and CSV export, making post-show documentation straightforward for venues, touring productions, or any situation where a written record of sound levels is required for compliance or review. For engineers already working inside Waves live hosts, it eliminates the need for dedicated hardware SPL meters or third-party software for routine level management.
