Audio Precision, part of Axiometrix Solutions, has introduced the new APx516B audio analyser.

Audio Precision, an Axiometrix Solutions brand, has introduced its HDMI2 + eARC module, a fully integrated digital I/O module enabling direct connection to HDMI2 and eARC audio devices.

Audio Precision, part of Axiometrix Solutions, released version 8.0 of its APx500 measurement software.

Smart speakers are a relatively new class of consumer audio device with unique characteristics that make testing their audio performance difficult. In this application note, Joe Begin, Director of Applications & Technical Support at Audio Precision provides an overview of smart speaker acoustic measurements with a focus on frequency response – the most important objective measurement of a device’s audio quality.

The latest update to its APx500 audio measurement software, version 6.1 has been released by Audio Precision (AP). It aids rub and buzz defect detection.

The APx517B acoustic analyser from Audio Precision is specifically designed, configured and built for the production-line testing of speakers, microphones, headphones, headsets and consumer electronics incorporating speakers and microphones.  

Audio Precision’s latest update to APx500 audio measurement software, version 6.0, supports multiple simultaneous input types, enabling the concurrent measurement of up to 16 channels of digital and 8 channels of analogue audio data.

Audio Precision has the PDM 16 module for the APx500 Series audio analysers. The new module offers simultaneous acquisition and measurement of up to 16 channels of PDM signals, making it the highest channel-count solution available for MEMS microphone and MEMS mic array testing.

An audio analyser that enables the use of APx audio measurement software with ASIO-capable third-party audio interfaces or sound cards has been released by Audio Precision. With the introduction of APx500 Flex, manufacturers can cost-effectively deploy the measurement capabilities, flexibility and quality of APx software to their production lines.

Improved sine generator frequency stability, lower system residual distortion, single-ended, balanced analogue output and an optional ADC test mode which provides VBias, a common mode DC Bias are features of the APx555 B Series analyser from Audio Precision. It is part of their B Series APx audio analysers.

The 144th International AES Convention will be the platform for the upcoming release of Audio Precision’s APx audio measurement software version 4.6.This latest edition of the test software will offer the ability to perform measurements using the log-swept sine chirp—such as acoustic response—in an open-loop configuration, an enhancement ideally suited to the test and evaluation of smart devices (e.g., smart speakers, smartphone...

Audio Precision announced the addition of a new speech intelligibility measurement option for APx500 audio test software based upon the ABC-MRT speech processing algorithm. Measuring speech intelligibility is an important capability for engineers designing and validating a wide range of communication systems, products and components, especially those related to public safety (e.g., police, fire, emergency) where intelligibility is critically impo...

The 376M03, a calibrated microphone system combining a 0.5in microphone cartridge with a phantom-powered preamplifier – the 426M16 – in its configuration has been added to Audio Precision’s line of measurement microphones. The preamplifier combines the precision of calibrated, standardised measurement microphones with ubiquitous mic accessories offering phantom power, balanced connections for improved immunity to induced noise, ...

A multichannel audio performance testing of A2B systems and components has been announced by Audio Precision, in collaboration with Mentor. A2B (Automotive Audio Bus) is the digital audio bus technology developed by Analog Devices to deliver high-quality audio over an unshielded, twisted-pair wire.

Audio Precision has announced a technology demonstration of multichannel audio bus testing at the upcoming AES 2017 International Conference on Automotive Audio. Conducted in cooperation with Mentor Automotive, the test scenario will centre on the digital audio bus technology developed by Analog Devices, Automotive Audio Bus (A2B), and the concept system will incorporate AP’s eight-channel APx585 audio analyser and Mentor’s A2B A...

 A collaboration between Audio Precision and LnK will address the SoundWire audio test needs of MIPI Alliance member companies by Combining an APx Series audio analyser with LnK’s protocol analyser creates a closed-loop measurement system for the real-time evaluation of chipset and mobile product designs incorporating MIPI’s SoundWire interface.

A trio of new measurement plugins have been introduced for Audio Precision’s intuitive and versatile APx audio test software. Each plugin integrates directly with APx software (version 4.3 or later) and adds new capabilities while allowing users to take advantage of built-in APx features such as limits, sequencer control, derived results and reporting.

The latest version of Audio Precision’s Android audio test app comes with support for Android versions 4, 5 and 6 (as well as Android N Developer Preview 5). The app allows fast, automated evaluation of new phones and tablets, including hands-free Bluetooth audio test without requiring the initiation of a phone call, saving developers’ time and ensuring that measurement results aren’t impacted by network performance.

The APx1701 Transducer Test Interface has been introduced by Audio Precision. The system integrates instrument-grade amplifiers and microphone power supplies for designers and production test engineers seeking clear insight into the behaviour of their electro-acoustic devices. With a signal-to-noise ratio of 134dB, the APx1701 provides 20dB of fixed-gain amplification from DC to 100kHz

A Speech Transmission Index (STI) plug-in for Audio Precision’s APx500 audio test software has been released. Created for engineers developing public safety (police, fire, emergency) communications and public address systems, as well as flight recorder devices, the APx STI plug-in provides measurement capabilities conforming to international standard IEC 60268-16 (2011).
