Next-Generation Audio & NVH Measurement Software

By using OpenTest you agree to its license and privacy statement

Measure Mode
Designed for real-time acquisition and analysis, it works with data acquisition hardware. Supporting both "analysis while acquiring" and "analysis after acquiring", it meets the needs of dynamic monitoring and flexible analysis.
Analysis Mode
Focused on offline in-depth analysis, it processes collected waveforms or data. It enables full-process analysis from data cleaning to analytical computation, helping explore in-depth data features.
Sequence Mode
Suitable for repetitive testing and production line scenarios, it connects the full "acquisition-analysis-storage-report" workflow. Focusing on batch execution and simple control, it improves repetitive testing efficiency.

Monitor
Continuous waveform monitoring and FFT spectrum analysis enable real-time identification of signal anomalies, such as clipping, clock jitter, and other issues. It simultaneously tracks key metrics, including RMS level, THD, SND, and frequency response, with configurable high-pass/low-pass filters and A/C/Z frequency weighting.

Open Hardware

OpenTest Open Hardware Access Protocol enables data acquisition devices to connect via mainstream audio protocols such as openDAQ, ASIO, WASAPI, and Core Audio. It also supports connections through private protocols like NI-DAQmx.

Open Plugin

OpenTest supports three-tier plug-in development and expansion using languages such as Python, MATLAB, LabVIEW, and C++. It covers all tiers: from the underlying custom algorithm plug-in integration (Algorithm), to the middle-tier theme customization (Theme), and to the upper-tier application module plug-in integration (Application). This full-tier coverage flexibly meets functional expansion needs in different scenarios.
