Stinger

STINGER Monolithic Audio Test PlatformProduct Introduction：STINGER is a software platform designed for the automated testing of audio quality during the research and development phase and the mass production phase of monolithic electroacoustic products.Based on virtual instrument technology, the entire system is composed of software combined with external hardware. The biggest difference from traditional testing instruments is that traditional testing instruments are integrated and cannot be adapted to replace hardware such as acquisition cards according to the needs of research and development and mass production.The STINGER audio testing system, based on virtual instrument technology, leverages the powerful computing capabilities of PCs, complete audio analysis functions, and comprehensive data storage features. With all settings integrated into a single module and default settings, the system is not only highly performant but also very easy to debug, meeting the needs for audio R&D and mass production testing, as well as the demand for simplified debugging processes.Product Details:STINGER is a software platform for the automated testing of audio quality during the research and development phase and the mass production phase of monolithic electroacoustic products.The software platform consists of three core modules: the Routine Test Items module, the Instrument Panel module, and the Test Object Settings module.The Routine Test Items module includes tests such as frequency response, phase, sensitivity, SNR (Signal-to-Noise Ratio), balance, distortion detection, and impedance testing, which are suitable for the research and development and mass production testing phases of monolithic audio products.The Instrument Panel module supports the use of Megatron's data acquisition cards as instruments, enabling the software interface to realize the functions of multimeters, oscilloscopes, signal generators, and other instrument capabilities.The Test Object Settings module includes creating or deleting various product projects, selecting test types (such as testing speakers SPK or microphones MIC, etc.), and configuring basic parameters such as channels, excitation signals, limits, units, data storage, MES, etc.Product Advantages:1、Hardware OpennessSTINGER is an open system for external hardware, allowing it to be paired with various external devices to form testing systems that meet the diverse needs of clients, from high-end to cost-effective solutions. For instance, clients with high requirements might opt for a premium testing system composed of Megatron's PM 6682 and PM 0084, while others might choose a more cost-effective setup with PM 8023 or PM 6143. The flexibility in hardware configuration ensures that it can adapt to the changing needs of monolithic R&D and mass production.2.Software Ease of DebuggingThe sequence editing feature has been eliminated, with all settings integrated into a single module and default settings applied. Functional buttons are enabled, and the interface for selecting test items and curve plotting has been simplified to a list selection, allowing users to quickly complete all settings and start testing, thus saving debugging time.3.Algorithm CompletenessSTINGER includes a comprehensive set of standard audio algorithms that can analyze frequency response, sensitivity, distortion, impedance, F0, phase, balance, polarity, and detect harmonics or abnormal sounds with a single sweep frequency, providing curves and data for judgment and saving test time.4.Optimized Testing LogicSTINGER utilizes multi-threading technology in data collection and analysis, enabling seamless collection without the need to wait for analysis completion before the next data collection. This significantly improves testing efficiency. Compared to traditional single-thread data collection and analysis logic, STINGER offers faster and more stable testing with the same signal length.5.High Cost PerformanceDeep optimization results in a compact and straightforward software. Accurate algorithms combined with simple operations make STINGER a highly cost-effective solution for audio testing needs.In summarySTINGER's streamlined and easy-to-debug design saves on labor costs, and its hardware openness allows it to meet various testing needs by pairing with different external hardware. This approach ensures that the platform remains adaptable and cost-effective, catering to a wide range of testing requirements across different projects and stages of product development.Main supported test itemsSingle unit speakerSingle unit diaphragmSingle unit microphoneSpeaker front chamber assemblyWired headphones
