Established Audio Measurement Software Updated To Version 5.0

Audio Precision has released APx audio measurement software version 5.0. With this release, the company 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.

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 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 their AP sales representative. 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.

 

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. For more information, Audio Precision.
