Multichannel analyzer simplifies audio test automation

Beaverton, Ore. — Audio Precision has added a new digital I/O module and new functionality to its APx500 series of multichannel audio analyzers with the release of version 2.1 of the APx500 measurement software. The new release focuses on simplifying automation in audio test. Improvements to the Measurement Navigator allow users to build a sequence of measurements across multiple signal paths with operator prompts, customized pass/fail limits, calls to external applications and automatic graphic reports.

Users can also employ the API to write custom applications or incorporate an APx analyzer into a larger automated setup. To support developers, the API documentation is supplemented with a library of sample tests written for LabVIEW, VB.NET and C#.

Other enhancements include a new digital I/O module that adds AES/EBU connectivity to the APx series, switcher support that extends the potential channel count of an APx analyzer to 192 in and out, and several new audio measurements such as noise, 6-digit frequency measurements and DC level over time.

Availability: APx500 v2.1 is available as a free download at http://ap.com/software. All new APx analyzers shipped after January 21 will come with the new AES/EBU digital I/O as standard. Customers with older APx units can upgrade their digital I/O module.
