The G4 LD Utility is a free program for use with your Models SoundAdvisor™ 831C, 831, or LxT sound level meters as well as Model HVM200 human vibration meters, and Spartan™ Model 730 and Model 730IS noise dosimeters. Connect, control, download, and view data from multiple devices simultaneously. Organize files and meters by project. View your data graphically and in spreadsheet format, generate reports, and easily export in Excel^® format for further data analysis. Examine graphs of multiple parameters and heat maps of octave band data. If your meter supports sound recording, play synchronized audio and edit data directly from the graph.

LD Atlas^TM is a free mobile app for use with your new Larson Davis equipment. Install LD Atlas on your phone or tablet – available for both iOS and Android – and connect to your Spartan^TM Noise Dosimeter Model 730, SoundAdvisor^TM Sound Level Meter Model 831C, and Human Vibration Meter Model HVM200. Connect to your meter and use LD Atlas to easily check on the status of your meter, make setup changes for a new measurement, analyze data, listen to recorded audio files, and even create and share PDF reports with your own company logo on them.

Analyzing noise and vibration data can be difficult. Its not often easy to see the patterns or recognize the nuances of complex data sets. Furthermore, presenting data in a way that is meaningful can be challenging, yet perhaps our most important task.

Tools for customizing and integrating our Sound Level Meters into your application. The Software Development Kit for the Model 831 and LxT Sound Level Meters interfaces smoothly and directly with Microsoft® or Linux® programming environments supporting Visual C++®, Visual C#®, HTML 5 and Javascript® programming languages. The SDK provides functionality to establish connection and fully control the Model 831 and LxT Sound Level meters over USB, network or modem connections. File downloads are supported and the SDK includes documentation and software for extracting data from files. Because of a reliance upon JSON, the SDK makes it easy to create modern, web based applications with minimal effort.
