APx500 Flex Audio Analyzer

Audio Precision
Enquiry Item

The APx500 Flex audio analyzer—comprised of APx500 measurement software and an APx500 Flex Key—allows you to select the ASIO-capable audio interface of your choice to use along with AP’s versatile and powerful APx audio measurement software. Start with the measurement options you need now, with the freedom to add additional measurements as your test requirements evolve. The APx500 Flex brings Audio Precision innovations such as one-click measurements, code-free automation and sophisticated reporting to off-the-shelf audio interface hardware solutions.

Across all measurements, the APx500 user interface is fast and intuitive. Just click to select a measurement, then click to add a filter. Drag limits to set pass/fail points right on the results graph. Effortlessly specify computations for derived results. Add defined measurements in a series and run them in an automated procedure called a Sequence. The APx generator can output steady tones, twin tones, sweeps, chirps, multitones, or play WAV files as arbitrary waveforms.

Repetitive bench tests and production testing can easily be automated with the built-in measurement sequencer and saved as a project that can be used with any APx analyzer. Production Test mode provides an optional simplified operator interface with multiple run statistics, created and supervised by a manufacturing engineer. Access the API if you prefer: documentation for VB.NET, C#.NET, MATLAB and LabVIEW is included.

Product Features

Flexibility
APx500 Flex is compatible with ASIO-capable audio interfaces. Choose the interface product that matches your budget and your application’s performance requirements.

Configurability
APx500 Flex continues AP’s tradition of highly-configurable measurement solutions. Select measurement options based upon your test requirements, with the ability to purchase individual measurements or value-priced Flex Packs.

Portability
Software licensing for APx500 Flex is facilitated by the APx500 Flex Key. Move your measurement licenses from one computer to another simply by moving your APx500 Flex Key.

Automation
Create custom interfaces and application-to-application automation using the comprehensive APx API. Extensive documentation and examples are provided for Visual Basic.NET, C#, MATLAB, LabVIEW, and Python. Projects and automation can be shared with other APx units anywhere in the world.

Common Software Platform
From a practical perspective, APx audio analyzers use a common software platform, making tests and results easier to share. All settings for a test are saved in a single project file, making it easy to replicate test setups between R&D and production facilities anywhere in the world. Project files are compatible with APx500 Flex. B Series, Legacy APx instruments and each project is self-contained, so there’s never any worry about dependencies or broken links. Users can even embed waveform files and images within a project file.

For sharing measurement results with customers, contract manufacturers or management, APx automatically generates rich graphic reports, with highlighted pass / fail limits and options to export as PDF, HTML, Excel, CSV, RTF or MATLAB files.

APx500 Flex Base Configuration (APX-FLEX-2CH):

• 2 channel ASIO interface
• File Analysis
• Sequence Mode
• Input Signal Monitors (including FFT monitor)
• Level & Gain
• THD+N
• Loudspeaker Production Test (including Rub & Buzz)
• Stepped Frequency Sweep
• Pass / Fail Measurement
• Signal Acquisition Measurement

Additional measurements, available either as individual options or as part of APx500 Flex Packs, are listed in the Options tab or the APx500 Flex audio analyzer data sheet.

Any ASIO-enabled audio interface should suffice with APx500 Flex. However, AP has thus far verified the compatibility of the audio interfaces listed below and configuration templates for these devices are included in APx500 software (v5.0.2 or later). Guides for setting up Flex with one of these audio interfaces are also available (see Downloads tab). Each of these verified compatible interfaces offer quality analog I/O (<90 dB THD+N, 192 kHz SR) and stable drivers with consistent delay.
