The TRACT SPL Meter addresses a fundamental gap in live sound engineering: real-time acoustic monitoring without breaking your workflow to launch external applications. Integrated directly into eMotion LV1 and SuperRack, this plugin delivers continuous sound pressure level measurement and logging from within your mixing environment, eliminating the context switching that disrupts concentration during live events.
The metering displays current SPL prominently while maintaining a maximum-level hold function, capturing the highest peaks reached throughout a session. Dual weighting options - A and C - allow you to match measurement standards to your venue's acoustic characteristics and regulatory requirements. The configurable threshold system provides immediate visual and audible warnings when levels breach your defined limits, giving you actionable feedback during critical moments.
What distinguishes the TRACT SPL Meter from standalone measurement apps is its integration with your mixing console and its documentation capabilities. The continuous logging function creates a time-stamped record of acoustic levels throughout an event, exportable as CSV data for post-show analysis, technical reports, or compliance documentation. This feature proves invaluable for venues tracking sound ordinance compliance, engineers validating system performance, and productions requiring acoustic proof of operation.
The tool's utility extends beyond live reinforcement into installed systems, broadcast facilities, and touring operations where integrated monitoring streamlines technical oversight. Its placement within your primary mixing interface eliminates the divided attention required when monitoring separate metering hardware or applications, making it a pragmatic addition for any engineer working within Waves' live ecosystems.
