In acoustic and vibration testing, engineering teams often find themselves jumping between multiple software tools and data acquisition systems from different vendors. Interfaces vary, workflows are fragmented, and new engineers can spend a significant amount of time just learning the tools before they can focus on the engineering problem itself.

OpenTest, developed by CRYSOUND, is a next-generation acoustic and NVH testing platform designed for engineers, researchers, and manufacturers. Built around the principles of an open ecosystem, AI-driven intelligence, and high compatibility, it allows users to complete the entire workflow—from acquisition to reporting—within a single software environment.

OpenTest supports three operating modes: Measure, Analysis, and Sequence, covering both laboratory validation and repetitive production testing. Core capabilities include real-time monitoring and analysis, FFT and octave analysis, sweep analysis, sound power testing, sound level meter functions, and sound quality analysis. The platform also provides standard test reports and dedicated sound power reports that comply with international standards.

On the hardware side, OpenTest connects to a wide range of multi-brand DAQ devices via mainstream audio protocols such as openDAQ, ASIO, and WASAPI, as well as optional proprietary drivers such as NI-DAQmx, enabling unified management of CRYSOUND SonoDAQ, RME, NI, and other devices within a single platform. On the software side, its modular plugin architecture exposes interfaces for Python, MATLAB, LabVIEW, C++ and more, making it easy for teams to package in-house algorithms and domain applications as plugins and deploy them within the same environment.

From Acquisition to Report: A Three-Step Quick-Start Workflow

1. Installation and Basic Connectivity – Let the Signals In

• Download the latest installer from the official website www.opentest.com and complete the installation.
• Connect your DAQ device to the PC; for your first trial, you can simply use the built-in PC sound card to run a quick test.
• In the OpenTest setup section, scan for available devices and select the devices and channels you want to use. Once added to the project, your basic connectivity is complete.

2. Run Basic Tests with Real-Time Analysis – See It First, Then Optimize

• In the channel management view, select the input/output channels you want to use and configure key parameters such as sensitivity, sampling rate, and gain.
• The system automatically activates the Monitor panel, where you can view real-time waveforms, FFT spectra, and key metrics such as RMS level and THD at a glance.
• When needed, you can enable the built-in signal generator to output excitation signals and use the recording function for long-duration acquisition, preserving data for later comparison and analysis.

3. Perform In-Depth Analysis and Reporting in the Measure Module – Turning Data into Decisions

• Switch to the Measure module to access advanced applications such as FFT analysis, octave analysis, sweep analysis, sound power testing, sound level meter, and sound quality—providing everything you need for deeper investigation.
• Use the data set functionality to review and overlay historical records, so you can compare different samples, operating conditions, or tuning strategies side by side.
• Waveforms and analysis results can be exported at any time. With the reporting function, you can generate test reports with a single click, closing the loop from test execution to final deliverables.

Who Is OpenTest For?

• New acoustic and vibration test engineers who want to establish a complete workflow quickly using a single toolchain.
• Laboratories and corporate teams that need to manage multi-brand hardware and consolidate everything into one unified software platform.
• Project teams in automotive NVH, consumer electronics, and industrial diagnostics that require high channel counts, automation, and AI-enhanced analysis capabilities.
