Audio Test

"A key reason for selecting National Instruments modular hardware over traditional boxed instrumentation for our application was the ease of integration with LabVIEW, which shortened our overall development time."

- Jacob Sondergaard - GRAS Sound & Vibration

Developing the G.R.A.S. Microphone Calibration System Using NI LabVIEW and National Instruments Hardware

NI PXI provides an ideal platform for audio test when combined with the high-performance NI 4461 modules. These modules feature two analog input and two analog output channels with 118 dB dynamic range. When you combine this with the flexibility of the PXI platform to expand channel count and generate other signals, you create the ideal hardware for audio test. NI AudioMASTER delivers a software architecture for quickly developing audio test steps and automatically placing them into NI TestStand software. This gives you a common tool from design and verification to final automated testing.
