Audio Precision has introduced the APx500 Flex audio analyzer, enabling the use of APx audio measurement software with ASIO-capable third-party audio interfaces or sound cards. The goal is for manufacturers to cost-effectively deploy the measurement capabilities of APx software in their production lines.
The APx500 Flex audio analyzer is Audio Precision’s APx500 measurement software operating independently of an AP hardware analyzer, with licensing controlled by an APx500 Flex Key. In lieu of a purpose-built analyzer, Flex can be paired with ASIO-capable third-party audio interfaces to create a cost-effective solution for a variety of acoustic and electrical test applications.
Measurement scenarios where hardware performance requirements are secondary to test system price — such as production line test of loudspeakers, headphones and microphones — are good candidates for Flex.
APx500 Flex allows users to take advantage of test development done in the R&D cycle through the ability to import project and template files developed for AP hardware analyzers, thereby potentially reducing test development time and maintaining consistency in test methodology across the organization.
APx500 Flex also makes for a powerful, portable audio measurement system for application engineers and QA technicians on the go.
APx500 Flex is being introduced in conjunction with the release of APx500 software v5.0.2, which provides improved ASIO support, including the calibration of inputs and outputs in V, Pa, and FS, automatic or manual delay compensation for compliant ASIO interfaces, and support for generator trigger, and acoustic and impedance measurements.
In its base configuration, Flex is configured for two channels and includes a core set of fundamental measurements and functionality: File Analysis, Sequence Mode, Input Signal Monitors (including FFT Monitor), Level & Gain, THD+N, Loudspeaker Product Test (including Rub & Buzz), Stepped Frequency Sweep, Pass/Fail, and Signal Acquisition measurement.
Configuration options for four or eight channels are also available, along with a trio of Flex Packs that each offer different groups of more advanced measurements. Perceptual audio measurements — including ABC-MRT and POLQA — can likewise be used with Flex. Finally, for the user that needs the base configuration plus just one more measurement, APx500 Flex has an à la carte menu of measurements from which to choose.
