Measurement software offers significant test time savings and faster reporting

Audio Precision has released version 8.0 of its highly advanced APx500 Measurement Software. Version 8.0 provides software performance optimisations that lower unnecessary computation and speed up sequence execution, and this produces notable test time savings and 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% saving in test times," says Daniel Knighten, general manager of Audio Precision. "This upgrade reinforces our philosophy of delivering a continuous program of improvements that not only saves customers time and money but also increases the value of their new and existing analysers."

This latest version includes updates to Bose SoneTrac, enabling users to make SoneTrac measurements in the exact way as Bose to experience more refined control over signal processing in detecting rub and buzz defects.

Version 8.0 also provides users access to THD+N results utilising the FastSweep stimulus in Continuous Sweep, Acoustic Response and Loudspeaker production test. As its name implies, this very fast stepped frequency signal sweep provides many advantages over a logarithmically swept sine (chirp) signal, including the capability 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 exact control of the number of discrete points used in measurements.

"Audio Precision's strength lies in providing elite audio analysis, audio measurement software, and a wide range of modules, options and accessories to support analog and digital audio measurement," Dan Knighten adds. "Our version 8.0 software aims to give engineers the analysis tools they need to support their own innovative product design and manufacturing processes."
