STINGER Single Audio Test Platform
Overview
STINGER is a software platform suitable for automated testing of audio quality in the R&D and mass production stages of single electroacoustic products.
Based on the virtual instrument technology, the entire system is composed of software and external hardware. The biggest difference from traditional test instruments is that traditional test instruments are integrated, and it is impossible to replace hardware such as acquisition cards for research and development and mass production.
The STINGER audio test system based on virtual instrument technology utilizes powerful PC computing capabilities, compete audio analysis functions, and comprehensive data storage functions. In addition, all settings are integrated into one module and defaulted, making the system have extremely high performance and at the same time With extremely high debugging simplicity, it meets the needs of single audio R & D and mass production testing and debugging simplification.
product details:
STINGER is a software platform suitable for automated testing of audio quality in the R&D and mass production stages of single electroacoustic products.
The software platform is composed of three core modules: routine test item module, instrument panel module, and test object setting module.
The routine test project modules include frequency response test, phase test, sensitivity test, SNR test, balance test, distortion test, impedance test, etc., which are suitable for the R&D and mass production of single audio products.
The instrument panel module supports using the data acquisition card of MegaSign as an instrument, and cooperates with the software interface to realize multimeter, oscilloscope, signal generator and other instrument functions.
The test object setting module includes creating or deleting each product item, selecting the test type (such as testing SPK or MIC, etc.), and configuring basic parameters such as channels, excitation signals, limit values, units, data storage, and MES.
Advances
[Openness of the hardware]
STINGER is an open system for external hardware, which allows STINGER to be matched with different external hardware to form a test system that meets the high, medium and low requirements of different customers. For example, customers with high requirements can choose Megason PM 6682+PM 0084 to form a high-end test system. test system, but you can also choose high-cost PM 8023 or PM 6143 hardware to form a test system suitable for your needs. The flexibility of STINGER hardware collocation is enough to meet the needs of R&D and mass production hardware replacement.
[Ease of debugging software]
Sequence editing functionality has been removed. All settings are integrated into one module and defaulted; the function button is enabled; the curve interface of the test item is called up and the list is selected, so that the user can complete all the settings for testing in a short time, saving debugging time.
[Algorithm integrity]
Built-in conventional audio algorithm, one frequency sweep can analyze the curves and data of frequency response, sensitivity, thd, impedance, F0, phase, balance, polarity, abnormal sound (higher harmonic) and other test items, and can perform Judgment, save testing time.
[Optimization of test logic]
STINGER uses multi-thread technology in data collection and analysis to achieve seamless collection, and the next data collection can be performed without waiting for the end of the analysis, which greatly improves the test efficiency. Test with the same stimulus signal length, compared with traditional single-threaded data acquisition and analysis logic, the test speed is faster and more stable!
[High performance-price ratio]
The in-depth optimization makes the software small and simple, and the accurate algorithm and simple operation make STINGER have a very high cost performance.
Conclusion:
STINGER streamlined and easy-to-debug design saves labor costs, and the openness of the hardware can meet different testing requirements according to matching different external hardware.
