Audio Precision releases APx500 v8.0 measurement software

Boasting “significant test time savings and much faster reporting of important measurements” the latest version of Audio Precision’s APx500 measurement software has been released. Version 8.0 features software performance optimisations that reduce unnecessary computation and speed up sequence execution, said the company. This results in significant test time savings and much faster reporting of important measurements such as THD+N.

“Version 8.0, along with our regular cadence of enhancements to APx500 software, allows users to take advantage of measurement scalability and efficiency, and benefit from as much as a 40 per cent saving in test times,” says Daniel Knighten, Audio Precision’s general manager. The upgrade is part of a continuous programme of improvements that are designed to save customers time and money, and also increase the value of new and existing analysers, he said.

The latest version incorporates updates to Bose SoneTrac, allowing users to make SoneTrac measurements in the same way as Bose to experience more refined control over signal processing in the detection of rub and buzz defects.

Version 8.0 also gives users access to THD+N results using the FastSweep stimulus in continuous sweep, acoustic response and loudspeaker production test. This extremely fast stepped frequency signal sweep offers several advantages over a logarithmically swept sine (chirp) signal, including an ability to sweep from low-to-high or high-to-low frequency, a lack of transient ripples at low or high frequencies, support for measuring harmonics above the 20th and precise control of the number of discrete points used in measurements.

Audio Precision provides audio analysis, audio measurement software and a range of modules, options and accessories to support analogue and digital audio measurement. Version 8.0 aims to give engineers the analysis tools they need to support their own innovative product design and manufacturing processes, added Knighten.

As part of its upgrade path, Audio Precision’s more recent software updates include v7.1 and v7.0. Version 7.1 offers integrated handling of units of measure and improve the presentation of input units, allowing users to scale any input in either the native unit domain of that physical input or in Volts, FS, Pascals, or Amps; while v7.0 enables the use of FastSweep in open loop testing scenarios, such as the testing of smart speakers.

Audio Precision also offers software subscriptions available in one, three or five-year increments, giving users an all-access pass to optional APx measurements for the duration of their subscription (excluding PESQ & PLQA) at no additional cost.

For over 35 years, Audio Precision has offered high-performance audio analysers, accessories and applications to help engineers worldwide design, validate, characterise, and manufacture consumer, professional and industrial audio products. It claims to offer market-leading THD+N performance, a wide range of digital interfaces, software that combines power with ease of use, and tools for electro-acoustic and perceptual audio testing. 

The company is headquartered in Beaverton, Oregon, USA and is part of Axiometrix Solutions, a test solutions provider comprised of globally recognised measurement brands, including GRAS Sound & Vibration and imc Test & Measurement.
