RME, the German manufacturer of premium digital audio solutions, has launched a preview version of its DigiCheck NG professional audio metering and analyzing software for Mac OS with 64-bit support. This preview version is a completely rewrite and a newly designed version of the company’s former DigiCheck software. DigiCheck NG is free and is compatible with Mac OS, up to Catalina. Dark Mode is also supported, and a Windows version will be released soon.

Klippel GmbH, one of the global leading companies in the field of measurement technology for loudspeakers and audio systems, founded in 1997 by Dr. Wolfgang Klippel, announced that Benjamin Barth has been appointed general manager to its managing board. Barth has worked with Klippel for the past eight years and his appointment will allow Wolfgang Klippel to focus more on research and education, while the company aims to expand its portfolio of products and services.

In this article for audioxpress, Ed Simon writes: "There seems to be controversy over what testing means in audio. Measuring a difference does not mean you can hear it. On the other hand, if my ears tell me there is a difference between two audio chains and I cannot measure it, that does not mean it is not there. Probably, I'm just using the wrong method to determine audio differences." And after trying to measure all sorts of things to compare which ones sounded fine - or not - he decided the next step would be to build a dedicated more sensitive measurement.

Studio Six Digital, designers of the popular AudioTools test and measurement system for the Apple iOS operating system, has discounted the AudioTools app by 50%, and the full suite of in-app upgrades by 30%. Now, they are also offering reduced pricing on all of their iOS and USB test & measurement microphones and audio interfaces to accommodate work-from-home technicians who have been displaced from their labs during the COVID-19 lockdown.

Purifi Audio, the Danish company founded by Bruno Putzeys, Lars Risbo, and Peter Lyngdorf together with a remarkable engineering team, promises Class D amplifiers with record-breaking performance (as well as speakers). Now, Bruno Putzeys made available a detailed report of his investigation on hysteresis distortion, which motivated the development of the company's products. As Putzeys describes, hysteresis in the ferromagnetic material of the amplifier output filter coil is what causes "a recognizable grainy texture in the sound."

Recognizing that working from home, away from the audio lab, is restrictive for many audio engineers, the support team at Listen, Inc. has produced a series of videos outlining some of the things that users can do using SoundCheck without all their usual test hardware, enabling developers and audio engineers to be productive when working from home. The videos span from cleaning up test sequences, to exploring offline analysis, using the recall step, to learning the new SoundCheck 18 features and more.

After a decade of widespread use, the Dayton Audio Test System (DATS) has acquired an impressive reputation for fast and accurate testing. Now, Dayton Audio has taken the easy-to-use audio test system and improved it in almost every way when creating the DATS V3 Computer-Based Audio Component Test System. This is an ultraportable audio test system that provides a reliable method for collection of Thiele-Small parameters, loudspeaker measurements and component measurements.

As many of its users already found out, audio test and measurement company Audiomatica has released a software update to its CLIO family of products with multiple new functions. CLIO 12.5 is dubbed by Audiomatica as "the next step forward" in the software, supporting and driving its existing FW-02 audio interface and ready to accommodate future developments. Operating system support has been extended to the latest Windows 10 (now supporting Secure Boot) and already offering 64-bit support.

Stuart Yaniger explores new possibilities in audio measurement systems, expanding on the basics of using sound cards combined with new accessible-to-all software tools, such as REW, and a recently improved measurement interface option. That option is the Linear Audio Autoranger Mk II Interface, which audioXpress’ Technical Editor Jan Didden designed a few years ago and which is now available as an improved Mk II version.

The world of communication and entertainment is evolving and consumer expectations for audio quality continue to increase, and with it the requirements for improved test equipment that can accurately predict the perception of human hearing and speech. A head and torso simulator (HATS) is an objective measurement instrument with built-in, human-like ear and mouth simulators that provides a realistic reproduction of the acoustic properties of an average adult human.
