Listen Releases SoundCheck 20 Audio Test Software Upgrade

The much anticipated SoundCheck 20 audio test software update is now released, and Listen is offering incentives to help users upgrade to the latest version.​​​​​ The motivations to upgrade are many, starting with the fact that SoundCheck 20 introduces Listen’s state-of-the-art perceptual distortion algorithm for end-of-line testing – Enhanced Perceptual Rub & Buzz. SoundCheck 20 also includes a host of new features for multichannel and communications testing.

The Listen AmpConnect 621 was unveiled earlier with the launch of SoundCheck 19 software, and is now available. The new multichannel, multifunction, high resolution audio test interface includes all the functionality required for audio testing in just one unit, including an amplifier, microphone power supply, line outputs and digital I/O. And with a sample rate of up to 192kHz, it supports measuring high resolution audio designs.

Following presentations at the 2019 AES International Headphone Conference in San Francisco or ISEAT in China, GRAS Sound & Vibration has now officially expanded its family of ear simulators with the launch of a model specially designed for the testing of high resolution audio capable headphones. Expanding on the GRAS RA0401/02 High-Frequency Ear Simulator, based on the standard IEC 60318-4 and extending the useful frequency range to 20 kHz, the new GRAS RA0403/04 Hi-Res Ear Simulator measures a frequency range to 50 kHz and beyond.
