Abstract: A system for modulating audio effects of speakers is provided. The system includes a selecting module, a playing module, a recording module, a time delay computing module and a modulating module. Based on these modules, the system is capable of determining a time difference and a pitch for each of the speakers, and modulating the time difference and the pitch for each of the speakers to a desired time difference and a desired pitch, so as to ensure that simultaneous sounds from each speaker arrive at a microphone at about the same time and with the same audio pitch. A related method is also provided.

Abstract: A system for testing hardware devices applies a multi-level architecture including a Graphical User Interface (GUI) level (10), a Dynamic Link Library (DLL) level (20), and a device driving level (30). The GUI level selects test items and test units for a test project based on test requirements, stores the test project in a test script file, configures test parameters for performing the test project, and stores the test parameters in a test parameter configuration file. The DLL level transmits test results of each hardware device (108) to the GUI level. The device driving level includes a device driving module (107) for obtaining test information on the hardware device, comparing the test information with standard information in the test parameter configuration file, and generating a comparison result. A related method is also disclosed.
