Audio Precision Announces APx Audio Software v4.6 with Chirp-Based Measurements for Smart Device Testing

Audio Precision announced the release of APx audio measurement software version 4.6, with a first public demonstration planned for the 144th International AES Convention in Milan. Included in this latest edition of the popular test software will be 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, smartphones).

HEAD acoustics has launched a new version of VoCAS (Voice Control Analysis System), the company’s software for evaluating voice control systems. The turnkey test solution now supports the company’s modular multi-channel labCORE front end. According to the Herzogenrath, Germany-based company, VoCAS offers manufacturers even more possibilities to test their ASR system (Automatic Speech Recognition) in vehicles, mobile phones or smart speakers objectively and reproducibly.

Audio Precision previewed its planned contributions to the 144th International AES Convention, Milan, Italy, May 23–26 at the NH Hotel Milano Congress Centre. Themed “The Power of Sound,” AES Milan will bring together audio professionals and advanced audio technologies from around the world for four days of audio immersion, experiences and networking. Audio Precision will promote three presentations, discussing smart speaker testing, speech intelligibility, and chirp-based measurements.

The March 2018 edition of audioXpress explores the latest advancements on Test and Measurement solutions and technologies. In this issue, we review G.R.A.S. Sound & Vibration's new RA040X ear simulators, and the IK Multimedia ARC 2.5 room correction system, with its included MEMS-based measurement microphone. We also discuss Measurement Microphones and Measurements for Smart Speakers, and conduct an interview Steve Temme, President of Listen, Inc. Gary Galo and Chuck Hansen pay tribute to the life and accomplishments of Victor Campos (1933-2017), and there is much more in this edition you don't want to miss!

A powerful and versatile all-in-one solution for a wide variety of applications, the new modular multi-channel front end labCORE from HEAD acoustics, introduces a powerful and versatile measurement instrument that expands the German company’s application scope. Due to its modularity, its wide selection of digital and analog inputs and outputs as well as its programmable interfaces, labCORE is an all-in-one solution for voice and audio quality measurements.
