SoundCheck Version 9.1 Released

Listen, Inc, announces the launch of SoundCheck® 9.1, the latest version of its popular PC and SoundCard based test and measurement platform. 

SoundCheck 9.1 introduces Listen’s new CLEAR (Cepstral Loudness Enhanced Algorithm for
Rub & Buzz) algorithm for perceptual Rub & Buzz analysis. This new algorithm uses a simplified
auditory perceptual model to measure the perceived loudness of the Rub & Buzz distortion in
phons rather than the more traditional dB SPL and % distortion units. This model better identifies
whether distortion due to manufacturing defects can be heard by the listener than conventional
measurements. In addition to a result which corresponds more accurately to the human ear, this
new test method also offers significant advantages for use on the production line. It is less sensitive to transient background noises than traditional methods, therefore is reliable in noisy environments. In addition, it is easier to set up.

Other upgrades in SoundCheck 9.1 include a refined RTA, the toption to select a fevice in the hardware editor using its device ID rather than its name, support for digital I/O cards with NUDAQMX drivers, Windows 7 compatibility and hardware key number display.
