APx500 Flex 音频分析仪（由APx500测量软件和APx500 Flex Key组成）使您可以选择所需的ASIO音频接口，与AP强大功能和多功能性音频测量软件一起使用。 从现在需要的测量选项开始，随着测试需求的发展自由添加其他测量。 APx500 Flex 将 Audio Precision创新引进现成的音频接口硬件解决方案。（例如一键式测量，无代码自动化和复杂的报告）

在所有测量中，APx500用户界面既快速又直观。 只需单击以选择一个度量，然后单击以添加过滤器。 拖动限制以在结果图上直接设置通过/失败点。 毫不费力地指定用于得出结果的计算。 依次添加定义的测量，并以称为序列的自动化程序运行它们。 APx发生器可以输出稳定音，双音，扫频，chi，多音或以任意波形播放WAV文件。

重复的台架测试和生产测试可以使用内置的测量定序器轻松实现自动化，并保存为可与任何APx分析仪一起使用的项目。 生产测试模式提供了可选的简化的操作员界面，该界面具有多个运行统计信息，这些统计信息由制造工程师创建和监督。 如果愿意，可以访问API：包括VB.NET，C＃.NET，MATLAB和LabVIEW的文档。

特征

灵活性
APx500 Flex 兼容支持ASIO的音频接口。 选择与您的预算和应用要求相匹配的产品。
可配置
APx500 Flex 继承了AP高度可配置的测量解决方案的传统。 根据您的测试要求选择测量选项，购买单独的测量值或价格合理的Flex 套装
可移植性
APx500 Flex 的软件许可是跟随APx500 Flex key。 只需移动 APx500 Flex Key, 即可从一台计算机移动到另一台计算机进行测量。
自动化
使用全面的APx API, 创建自定界面和应用程序到应用程序的自动化。 提供了有关 Visual Basic.NET，C＃，MATLAB，LabVIEW和Python的大量文档和示例。 项目和自动化可以与世界各地的其他APx 设备共享。
通用软件平台
从实际的角度来看，APx音频分析仪使用通用的软件平台，从而使测试和结果更易于共享。 测试的所有设置都保存在一个项目文件中，从而可以轻松地在全球任何地方的R＆D和生产设施之间复制测试设置。 项目文件与APx500 Flex兼容。 B系列，旧版APx仪器和每个项目都是独立的，因此无需担心依赖关系或断开的链接。 用户甚至可以将波形文件和图像嵌入项目文件中。 
为了与客户，合同制造商或管理人员共享测量结果，APx自动生成丰富的图形报告，并带有突出显示的通过/失败限制和选项，以导出为PDF，HTML，Excel，CSV，RTF或MATLAB文件。

INDIVIDUAL MEASUREMENT OPTIONS

In addition to Flex Packs, APx500 Flex measurement options can be purchased individually, allowing users to configure their test system specifically for their application requirements. Measurements can be added to an APx500 Flex Key when ordering a new APx500 Flex analyzer or they can be delivered electronically to an existing APx500 Flex Key. Please consult the APx500 Flex data sheet for a complete list of measurements.

PERCEPTUAL AUDIO TEST OPTIONS

Perceptual Audio Test: POLQA (SW-POLQA-2)
Perceptual audio measurement returns a subjective assessment of speech quality using the next-generation POLQA algorithm for wide-band speech devices or devices with acoustic coupling. (Successor to PESQ with support for HD Voice, 3G, 4G/LTE and VoIP technologies)

Perceptual Audio Test: PESQ (SW-PESQ)
Widely-used, enhanced perceptual measurement for subjective assessment of speech quality on low-bandwidth devices. (PESQ algorithm)

Speech Intelligibility: ABC-MRT Measurement (SW-ABC-MRT)
The APx ABC-MRT plugin is a software option for APx500 audio measurement software that provides speech intelligibility measurement based upon the ABC-MRT speech processing algorithm developed by the Institute for Telecommunication Sciences (ITS) of the United States National Telecommunications and Information Administration (NTIA).

Speech Intelligibility: Speech Transmission Index (SW-STI)
SW-STI is a plug-in for conducting Speech Transmission Index (STI) measurements using the STIPA method.
