Audio Precision Announces DAQ Driver For LabVIEW™ Software
Enables easy access to APx515 as a data acquisition platform
BEAVERTON, Ore., Sept. 3, 2015 /PRNewswire/ -- Audio Precision, the recognized standard in audio test, today announced the release of their newest driver for National Instrument's LabVIEW software. Developed with a broad range of signal acquisition applications in mind, this driver streamlines and simplifies the integration of the APx515 analyzer as a robust, high-quality front end to LabVIEW-based measurement environments.

DAQ Driver and Audio Test
Easy addition of the APx515 to a LabVIEW environment is achieved via the DAQ driver's collection of Virtual Instruments (VIs)—a function or program created in LabVIEW—for initializing the hardware and configuring a wide range of settings, including input and output channels, sample rates, trigger conditions, signal generation, and signal acquisition. The driver is based on a low-level C++ measurement library, adheres to National Instrument's standard guidelines for instrument drivers, and has a very small memory footprint. Additionally, it enables control of the APx515 completely independent of the APx500 control software.
The APx515 DAQ driver's feature set includes support for the LabVIEW waveform data type, arbitrary waveform generation and waveform acquisition. Additionally, the APx DAQ driver has audio test functionality that makes it unique, including sine generator with two independent channels; optional dither for digital signal generation; high- and low-pass input filters; input signal weighting filters; and a wide range of meters for audio metrics. Provision of these features enables LabVIEW users to easily make industry standard audio measurements while eliminating the need to develop their own analysis routines.
Applications Beyond Audio
In addition to audio test, the LabVIEW DAQ Driver for APx515 opens up a world of possibilities in non-audio signal acquisition. Users can easily integrate the high-quality, robust APx515 analyzer front end into any LabVIEW application involving signal generation and analysis from DC to 90 kHz. Potential uses include vibration analysis, acoustic intensity, ultrasound, infrasound, analysis of dynamic signals (e.g., force, pressure, strain), power supply quality, and more.
"With the APx515 analyzer already renowned worldwide for precision and reliability in production test environments," stated Dave Schmoldt, Audio Precision CEO, "our new DAQ driver allows LabVIEW users a fast path to incorporating that instrument into their LabVIEW-based measurement systems, whether audio-focused or not."
