SPL Sense

Software for visualising measured values and protecting against noise level exceedances

SPL Sense

Software for visualization and live view of the recorded measured values

Features

SPL Sense can be used to visualize and record the measurement data captured with an SPL Tools sensor. You can put together your own Liveviews. Decide what you want to see. The measurement data can be transferred directly to the SPL Cloud and exported for your own archiving or sharing.

With the SPL Sense Leveler plugin for QSYS you have the sound pressure level under control. The signal is automatically adjusted taking the audience level into account. This allows you to prevent overdriving. The audience can sing along as loud as they like without the DJ level being adjusted.

System requirements

macOS 10.15, Windows 10 v.1607 or later.

On Windows operating systems, SPL Sense is based on WebView2. The SPL Sense installer downloads the “WebView2 Runtime” during installation if it is not already installed on the target computer. An Internet connection should therefore be available during the first installation.

In the quick installation guide for SPL Sense for Linux you will find all the relevant information on how to install SPL Sense on a device with a Linux operating system. This version also offers the option of displaying SPL Sense in parallel from several computers via a browser.

For the plugins you need a QSYS Core in conjunction with SPL Sense version 1.1 or newer.
