Audio test specialist Audio Precision has released v8.0 of its APx500 measurement software. The company claims it can reduce test times by up to 40% by introducing software performance optimizations that reduce computation and speed up sequence execution.
Version 8.0 gives users access to THD+N results using the FastSweep stimulus in Continuous Sweep, Acoustic Response and Loudspeaker production test. This stepped frequency signal sweep offers 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’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,” says Daniel Knighten, Audio Precision general manager. “Version 8.0 software aims to give engineers the analysis tools they need to support their own innovative product design and manufacturing processes.”
The upgrade also 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.
