AudioMASTER is a set of versatile audio test solutions based on TestStand for analog and digital audio validation and production test. AudioMASTER for Analog Audio combines an NI 4461 dynamic signal acquisition (DSA) device, featuring 24-bit resolution, a 204.8 kS/s sample rate, two inputs, and two outputs, or an NI 4462 DSA device, featuring 24-bit resolution, a 204.8 kS/s sample rate, and four inputs, with AudioMASTER software for the acquisition, analysis, and generation (NI 4461 only) of analog audio. You can use AudioMASTER for Digital Audio for the acquisition and analysis of S/PDIF audio with coaxial, optical, or XLR connections. These combinations deliver a comprehensive automated test solution with the performance otherwise found in only high-end audio analyzers.

Using AudioMASTER for Digital Audio, which includes an NI 7813R R Series reconfigurable I/O device, a CB-2180 (two-input) or CB-2181 (one-output, one-input) digital audio accessory, and AudioMASTER software, you can generate, acquire, and analyze S/PDIF signals encoded in linear PCM or AC-3 formats. For linear PCM, AudioMASTER supports two-channel formats with 8, 16, 20, or 24 bits per sample and sampling frequencies from 22 kHz to 192 kHz. For AC-3, AudioMASTER supports up to 5.1 channel configurations for which there are five channels representing right front, center, left front, right rear, and left rear plus one low-frequency effect (LFE) channel.

The CB-2180 provides two input channels, each with a software-selectable BNC for coaxial or TOSLINK for optical connection. You can connect up to four CB-2180 digital audio accessories to a single NI 7813R device to provide a total of eight S/PDIF inputs. The CB-2181 provides one input channel and one output channel, each with a software-selectable BNC for coaxial, TOSLINK for optical, or XLR for AES3 connection. You can connect up to four CB-2181 accessories to provide four S/PDIF outputs and four S/PDIF inputs. With multiple input and output channels available per NI 7813R module, AudioMASTER greatly simplifies the test fixture required for multidevice testing.
