Audio analyzer module adds new Bluetooth codecs

-September 26, 2017


Bluetooth audio has replaced stereo jacks in cars, cell phones, computers, and just about everywhere else. To test audio quality, Audio Precision has added the Bluetooth Duo module as an accessory to its APx series of audio analyzers. Containing source and sink antennas, the Duo module has a separate transmitter and receiver for communicating with a Bluetooth audio device under test.



Compliant with Bluetooth 4.2, the APx Bluetooth Duo module increases support for Advanced Audio-Distribution Profile (A2DP) codecs available to Bluetooth-equipped to include Apple's Advanced Audio Coding (AAC), Qualcomm's aptX, aptX-HD, and aptX-LL, and Bluetooth's default Subband Coding (SBC). When using Audio Precision's Perceptual Audio (PESQ) Option for APx500, the Bluetooth Duo generates Mean Opinion Score (MOS) values.

Price: $4,995 when ordered with a new APx555, APx52x Series or APx58x Series audio analyzer.
