As Audio Precision prepares to roll out its latest audio analyser, the APX555, the company has also released version 4.0, of its APx500 audio test software. Version 4.0 provides a multi-mode user interface for the entire APx family of analysers, adding Bench Mode to complement the software’s existing approach of user-selectable automated measurement sequences, now called Sequence Mode.

With APx systems used throughout the product development process—from design, debug and validation to final production test—v4.0 was developed with system flexibility in mind. APx500 software now offers easy switching between Sequence Mode’s fast and efficient menu of measurements and Bench Mode’s free-form, real-time operation of generator and analyzer for feedback on any selected parameters.

The flexibility and utility of APx test systems has them spanning the product life-cycle, whether the device under test (DUT) is an audio converter, a hearing aid, an automotive infotainment system or pro-audio mixing console. Measurement reliability from the development lab to the manufacturing line is incredibly important in understanding DUT performance as it migrates from prototype to product and APx software supports such test consistency by enabling sharing of projects created in Sequence Mode.
