Rational Acoustics Releases Smaart SPL

Woodstock, CT January 6, 2020– Rational Acoustics, developers of the award-winning Smaart audio analysis and optimization software, are pleased to announce the release of their new standalone SPL measurement & monitoring software program, Smaart SPL.

Smaart SPL offers the complete SPL measurement feature set from Rational’s flagship Smaart v8 program in a purpose-built, standalone package, with an interface built for simplicity and speed. Smaart SPL offers a powerful, full-featured solution for monitoring, metering, and logging SPL, with a format and a price point more accessible to users who don’t require the FFT analysis functionality of Smaart v8.

“SPL monitoring in the live sound industry has become incredibly important from a performance standpoint, as well as for both health and safety and legal reasons.” says Rational Acoustics Founder and President Jamie Anderson. “With the release of the Smaart v8.4 update in November 2019, we included a major expansion of Smaart’s SPL monitoring capabilities and it was a logical next step for us to make those features available to a wider audience as a separate, lower-cost standalone package.”

Smaart SPL is designed for mix engineers, system technicians, rental houses and any type of venue where audio levels must be accurately measured, logged, and reported. Smaart SPL’s intuitive and easily readable interface makes professional level SPL monitoring readily accessible to anyone using a macOS or Windows based computer system.  And because it is based off Smaart v8’s multi-input/multi-device audio acquisition format, multiple simultaneous measurement inputs and displays are not limited in any way by the software.  It is possible to connect and calibrate as many inputs to Smaart SPL and monitor as many locations as you’d like, as long as you have the hardware infrastructure to support it.

For general SPL measurements, where Class 1 or Class 2 compliance is not required, Smaart SPL can be used with any user-supplied acoustic test and measurement microphone in conjunction with an SPL calibrator and a microphone preamp / audio interface.  In cases where Class 1 or Class 2 compliance is a requirement, Smaart SPL has been designed to work with SG Audio’s 10EaZy hardware for a turnkey calibrated solution.

During a show, Smaart SPL’s fully configurable meter grid is a dashboard for critical showtime metrics with green, yellow and red “traffic light” threshold controls for each metric. The single, intuitive control bar gives quick access to configuration functions and logging actions, and the SPL history timeline shows data collected over the entire logged, or live-logging, event. For compliance and post-event reporting, Smaart SPL creates logfiles in .txt format and can generate SPL summary reports containing all event details as well as statistics for each metric and any alarm violations that occurred during the period.

Where remote monitoring is required, Smaart SPL includes an integrated web interface that allows real-time viewing of meters and the SPL history timeline via the web browser of any desktop or mobile device on the same network.

Because of its standalone design, Smaart SPL is easily deployed by users without any previous experience with Smaart software. Existing Smaart users will find Smaart SPL an easy and inexpensive way to add Smaart’s SPL monitoring capabilities to additional computers where FFT measurement capability is not required.
