TRACT SPL Meter monitors and logs sound pressure levels directly inside Waves live mixing environments.

Keep SPL visible directly inside the eMotion LV1 mixer or the SuperRack plugin host, without relying on a separate application for everyday level monitoring. A large readout shows the current SPL at a glance, maximum-level hold tracks the highest level reached, and a clear warning appears whenever your own threshold is exceeded. For documentation and post-show review, measurements can be logged and exported to a CSV file.
