SoundCheck 18 New Features 

More details

SoundCheck Software is the heart of a SoundCheck test system. It generates all the test signals, performs analysis and displays results according to the user’s configuration.

SoundCheck软件是SoundCheck测试系统的核心。它会生成所有测试信号,执行分析并根据用户的配置显示结果。

Sound Check System

While it is an extremely powerful and flexible product, its capabilities can be described in 3 parts, First, the test Sequences (how tests are configured by the operator), Second, Virtual Instruments  (software implementation of standard audio test equipment) and the thrid one,Data Analysis (the various analyses that SoundCheck can perform on your data)

它是一个非常强大和灵活的产品,但它的功能可以分为三个部分来描述:第一,测试序列(如何由运营商配置测试),第二,虚拟仪器(标准音频测试设备的软件实现)和第三部分,数据分析(SoundCheck可以对您的数据执行的各种分析)

SoundCheck 18, the latest release of Listen, Inc.’s flagship audio test and measurement system, contains many new features focused on automation and simplicity. Some of these are specifically designed for large-scale integration in factory environments, while others are designed to accelerate R&D testing, particularly where multiple channels are required and/or voice-activated devices are being tested.

Test configuration data, such as limits, test levels, and test signals, can now be passed into SoundCheck from external programs using TCP/IP commands. By externally storing parameters, a single sequence can be used for multiple products, simplifying the number of sequences that a large organi­zation needs to maintain, and reducing test configuration time. This functionality is also useful for applications where a sequence needs to be run many times with different parameters, for example, testing voice recognition with a range of voices or test levels, or where SoundCheck tests are run as part of a larger automated test framework controlled using Python, C#, Visual Basic, LabVIEW, etc.

现在可以使用TCP / IP命令从外部的程序将测试配置数据(例如限制,测试级别和测试信号)传递到SoundCheck中。 通过在外部存储参数,单个序列可以用于多个产品,从而简化了需要维护的序列数量,并减少了测试配置时间。 此功能对于需要使用不同参数及多次运行序列的应用程序非常有用。例如在使用各种语音或测试级别测试语音识别的时候,或者在使用Python,C#,Visual Basic,LabVIEW等控制的大型自动化测试框架中运行SoundCheck测试的时候十分有用。

Setup time is reduced with true plug’n’play hardware configuration. Listen and Portland Tool & Die interfaces are simply connected via the USB cable, and the software automatically creates input and output signal paths and populates parameters such as sampling rate and calibration values. Furthermore, when substituting devices of the same type, SoundCheck will re-use the configuration pre­viously set up, either manually or during a sequence, so that signal paths and sequence configurations do not need to be updated. This offers significant time-savings when deploying a sequence over multiple stations accelerating set-up time for large-scale operations. New TEDS Support (with compatible Listen hardware) enables automatic identification, configuration and calibration of TEDS microphones and accelerometers, also saving time on initial hardware setup or whenever hardware is changed.

即插即用的硬件配置可减少设置时间。Listen 以及Portland的模具接口只需通过USB电缆连接即可使用,软件会自动创建输入和输出信号路径,并填充诸如采样率和校准值之类的参数。此外,当替换相同类型的设备时,SoundCheck会手动或在序列操作中重新使用先前设置的配置,因此无需更新信号路径和序列配置。当在多个工作站上部署序列时,可以节省大量时间,从而加快了大规模操作的设置时间。 支持新的TEDS(具有兼容的Listen硬件)可以自动识别,配置和校准TEDS麦克风和加速度计,还可以节省初始硬件设置或更改硬件时的时间。

The development and optimization of test sequences has been simplified with improvements to gain control selection. Similarly, sampling rate management has been streamlined with automatic latency rate adjustment for devices where latency varies with sampling rate, and the ability to set sampling rate in the stimulus editor. Sampling rate when using WAV files is also now automatically adjusted, making it simpler to make measurement with wave file signals such as speech or music.

通过改进增益控制选择,简化了测试序列的开发和优化。 同样,通过对延迟随采样率变化的设备进行自动延迟率调整,从而简化了采样率管理,并具有在激励编辑器中设置采样率的功能。  现在,还可以自动调整使用WAV文件时的采样率,可以更轻松地通过语音或音乐等波形文件信号进行测量。

For MEMS microphone tests, the Portland Tool & Die MEMS interfaces can now be controlled from within SoundCheck for faster setup as well as greater measurement reliability as the device settings can be built into the test sequence. Se­quences using the R&D grade DCC-1448 interface will also work seamlessly with the production-grade PQC-1448, making it much simpler to transition sequences from the R&D lab to the produc­tion line.

MEMS麦克风测试,现在可以从SoundCheck中控制Portland的模具接口MEMS接口,以实现更快的设置以及更高的测量可靠性,因为可以将设备设置内置到测试序列中。 使用R&D级DCC-1448接口的序列也可以与生产级PQC-1448无缝协作,从而使从R&D实验室到生产线的转换过程变得更加简单。

Additional new features include WASAPI driver support for improved multichannel capabilities, and enhanced digital I/O control for easy conversion of sequences between hardware options.

其他新功能包括WASAPI驱动程序支持(用于改进的多通道功能)以及增强的数字I / O控制,可在硬件选项之间轻松转换序列。
