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.

In acoustic and vibration testing, flexibility is a decisive factor—especially when test requirements evolve rapidly. SonoDAQ, with its modular, scalable architecture, helps users easily manage everything from simple tests with a single device to complex, large-scale, multi-channel data acquisition. Whether in laboratory environments or industrial sites, SonoDAQ provides efficient, accurate data acquisition solutions, maximizing the adaptability and scalability of the system.

Easy Testing with One Device, Scalable Expansion with Multiple Devices

When testing requirements are modest, such as road tests or basic vibration testing, SonoDAQ Pro can easily meet the required number of channels with a single device. In this case, users only need one device to perform high-precision data acquisition, which is efficient and helps avoid unnecessary upfront hardware investment.

However, as testing needs increase, especially in scenarios that require numerous sensors or synchronized multi-channel acquisition, SonoDAQ offers flexible expansion solutions. Users can connect multiple SonoDAQ Pro units in a daisy-chain or star topology to achieve large-scale data acquisition. For example, when conducting NVH testing or sound and vibration testing for large equipment, users can add more devices as needed, scaling up to hundreds of channels while ensuring high-precision synchronization across all devices.

This scalability allows customers to avoid purchasing entirely new acquisition systems each time. By simply cascading existing SonoDAQ Pro units, they can easily cover more complex testing needs and avoid the common issues of device redundancy and high costs seen in traditional systems.

Flexible Configuration to Meet Various Needs

Even without large-scale acquisition needs, SonoDAQ remains highly flexible. With its modular design, users can easily adjust and reconfigure the system according to changing test requirements. For instance, if only temperature or strain signals are required, users can simply select the corresponding module and insert it into the chassis, without purchasing a new mainframe.

This design makes SonoDAQ suitable for everything from simple laboratory tests to complex field tests. Users can expand the system as needed, without worrying about future expansion limits. Whether it’s basic data acquisition or advanced signal analysis, SonoDAQ provides accurate, flexible data acquisition solutions, significantly enhancing testing efficiency and cost-effectiveness.

Flexibility Brought by Modular Design

The modular design of SonoDAQ is the core of its flexibility. Users can select different input modules, output modules, sensor interface modules, and more based on project requirements, and easily plug-and-play or upgrade them as needed. Whether it’s adding more sensor channels or expanding with new functional modules, users can quickly implement changes by swapping modules, without affecting the normal operation of the existing system. This design ensures long-term device usability and enables SonoDAQ to adapt to ever-changing test requirements.

When future requirements change, such as testing additional signal types (e.g., temperature, pressure, strain), SonoDAQ Pro can easily meet these new testing needs by simply swapping modules, allowing the overall system to continue running efficiently without the need for a full system overhaul.

For example, an automotive manufacturer needs to perform NVH testing. Initially, they may only need 4–8 channels for in-car noise testing. In this case, engineers can use a single SonoDAQ Pro device to complete routine testing tasks. When they need to expand the testing scope and add more sensors (such as measuring vibration, strain, or temperature at different locations), they can simply daisy-chain multiple SonoDAQ Pro devices together. Through synchronization technology, they can ensure data consistency across all devices without redesigning the system or changing existing test procedures.

Beyond automotive NVH, the same scalable architecture can be applied to aerospace components, industrial machinery, and even high-channel-count consumer electronics testing.

Expand as Needed, Effortlessly Tackle Any Testing Challenge

The flexible expansion capability of SonoDAQ allows it to scale from simple single-channel testing to large-scale multi-channel data acquisition. Whether it’s for in-vehicle testing, industrial monitoring, or scientific research, SonoDAQ provides accurate, reliable data acquisition solutions. Its modular design and flexible system topology not only meet current needs but also enable quick adaptation to evolving testing scenarios in the future. Choosing SonoDAQ means moving away from fixed hardware configurations and instead adjusting the system based on needs, ensuring smooth, repeatable execution of every test.
