Industry-leading analog performance, flexible software with a multi-mode UI, and a wide range of digital I/O and software options make APx the most powerful and versatile series of instruments Audio Precision has ever produced.

More connectivity options with higher performance specifications than any other analyzer in the world!

Every interface option is fully integrated into our software, eliminating uncertainty and enabling faster test setup, while our test software provides unique measurement views and results that are trusted everywhere.

Versatility
Delivering analog, digital and acoustic test capabilities in single instrument, APx500 Series analyzers are the epitome of versatility.

Performance
From the lowest THD+N and crosstalk to the flattest response and widest bandwidth, Audio Precision analyzers are at the forefront of audio measurement.

Connectivity
Beyond traditional analog and digital audio interfaces, AP analyzers offer options for Bluetooth, Digital Serial, HDMI and PDM connectivity. Likewise, AP instruments are designed with automation in mind, supporting (model dependent) LabVIEW, VB.NET, C#.NET, MATLAB, AP Basic or GPIB.

Multichannel
Choose from analyzers with native two-, four-, eight-, or sixteen-channel configurations.

Accredited Calibration
Audio Precision is accredited by A2LA under ISO/IEC 17025:2005, the most stringent standard. Calibration provides documented and traceable verification that instruments meet or exceed all of their published specifications.

 

   

 

ADC Test Mode and Enhanced Performance Arrive with B Series APx555

   
   

Audio Precision introduces B Series APx Analyzers, including improved specs and capabilities for flagship audio analyzer

   
   

BEAVERTON, OREGON, December 18, 2018: Audio Precision announced today the introduction of the APx555 B Series analyzer, part of their B Series APx audio analyzers. Already the market leader in audio test performance, the second-generation APx555 offers improved sine generator frequency stability, lower system residual distortion, single-ended, balanced analog output and an optional ADC test mode which provides VBias, a common mode DC Bias.

   
   

B Series APx555 High-Performance Audio Analyzer

The arrival of the B Series APx555 audio analyzer brings several enhancements to the analog high-performance sine generator that will have broad appeal to developers of high-performance audio devices such as compressors, limiters, amplifiers, codecs and digital signal processors. This enhanced analog generator (EAG)—standard with B Series APx555 analyzers and available as an upgrade for Legacy APx555 systems—provides several improvements in its low distortion sine generator and high-precision sine analyzer, including improved sine generator frequency stability with an accuracy of <30 ppm. The system can now also generate low-distortion analog sine burst signals from 5 Hz to 100 kHz and allows users to independently invert the signal polarity of balanced channel outputs. Finally, the B Series APx555 has lower system residual distortion, with THD+N improvement above 50 kHz (−2 dB) and THD improvement above 5 kHz (varying from −2 to −5 dB).

   

 

   

 

Audio Precision Releases APx Software Version 5.0

   
   

Adds transfer function measurement (also knows as a Dynamic Signal Analyser), enabling cross-spectral analysis of arbitrary, broadband signals

   
   

BEAVERTON, OREGON, December 18, 2018: Audio Precision announced today the availability of APx audio measurement software version 5.0. With this release, AP has added the ability to measure the transfer function of electronic audio and electroacoustic devices using any broadband signal. Release 5.0 also enables electronic activation of software option licenses, eliminating the iButton requirement for such options with earlier versions of APx audio measurement software.

   
   
Transfer Function (Dynamic Signal Analyser / Dual Channel FFT Analyser)
The transfer function measurement provides the complex frequency response function for a device, including the magnitude and phase (or real and imaginary components), using any broadband signal. This feature, a powerful addition to APx software’s Sequence Mode, allows any APx analyzer to be used as a multichannel dynamic signal analyzer or as a so called dual-channel FFT analyzer.

With transfer function and any broadband signal, including speech, music, or noise, APx users can now assess the complex frequency response, coherence, and impulse response of their device or system. AP’s transfer function provides gapless and overlapped analysis of multiple acquisitions. It also includes a ground-breaking signal-based triggering that eliminates the need for a pilot tone in open-loop test applications, making it ideal for test of “smart” audio devices.

   
   

APx500 Version 5.0 & Software Licensing
With release 5.0, Audio Precision is adopting a software licensing model that better reflects the added value of new capabilities, such as the transfer function measurement, and the organization’s continued investment in developing new APx software features. As part of this change, AP will move to establish an annual cadence of major releases with new features and measurement capabilities.

Beginning December 18, new APx analyzers, whether B Series or Legacy, will ship with version 5.0 software and one year of software maintenance, effectively licensing that instrument for APx version 6.0 when it is released, as well as any minor releases that occur between versions 5.0 and 6.0. Customers who purchased an APx analyzer in 2018 are entitled to a complimentary license for version 5.0 and should contact Vicom. Options for extended software maintenance are also available.

Owners of Legacy APx analyzers purchased in 2017 or earlier will need to purchase a software upgrade to use version 5.0 and the new transfer function measurement. Software maintenance contracts are likewise available for purchase, entitling the user to an additional major software release.

“Adjusting our approach to appropriately recognize the value of our software alongside our hardware is overdue,” said Mike Flaherty, Audio Precision Chief Executive Officer. “Establishing our new software licensing model does just that, while it also establishes a consistent release cadence as we continue to enhance the capabilities of the APx platform. All while providing market-leading, and complimentary, technical support to our customers, regardless of instrument generation.”

Release 5.0 is now shipping with all new APx audio analyzers, B Series or Legacy, and is compatible with all analyzers in the APx500 Series. An APx KeyBox is required to run v5.0 on Legacy APx analyzers and a KeyBox is shipped with all new Legacy systems. Software licensing, including specialized measurement options, will be tied to a specific analyzer (via serial number) and can now be fulfilled electronically.
