SoundCheck Version 10.1 Released
Listen, Inc, announces the launch of SoundCheck® 10.1, the latest version of its popular PC and SoundCard based test and measurement platform.
SoundCheck 10.1 introduces several new features which expand the versatility of the software for both R&D and production line applications, as well as some features which simplify operation.
A selection of standard waveform filters are now also available (in addition to the arbitrary waveform filters introduced in SoundCheck 10.0), including Butterworth high-pass, low-pass, band-pass and band-stop filters. These are useful for conditioning stimulus and response waveforms when you are making time domain measurements, or for band pass analysis in the time domain (e.g. speech intelligibility or attack and release testing).
The RTA analysis algorithm has been updated so that in addition to calculating the RTA spectrum of the response waveform, it now allows the option to calculate the spectrum of the stimulus as well as the overall frequency response (comparing the response to the stimulus). This is useful when analyzing non-stationary signals, for example speech signals in telephony where compensation needs to be made for a non-flat stimulus.
The Zwicker Loudness feature (introduced in SoundCheck 10.0) has been extended with a new option to output the Loudness Spectrum to the Memory List. The units for the X-axis are selectable between Hz and Bark scale. The loudness spectrum allows the user to determine which frequencies are responsible for the loudness, and is useful for analysis of telephone ring tones.
Operation is simplified with a new memory list search function. This feature allows the user to find and highlight all items which match a search string. Advanced searching through the use of regular expressions is also possible as described in the context sensitive help window of the search string. This is particularly useful when the memory list contains a large number of curves such as in production line applications. Also in the memory list, the 'Protect’ and ‘Autoprotect’ features now append the serial number to the protected curve name. This offers a quick and easy way to annotate data by typing a comment into the serial number field.
Finally, there are some upgrades to existing algorithms, including the CLEAR Perceptual Rub & Buzz algorithm and the Attack and Release algorithm (used for measurement of automatic gain control in telephony and hearing aids).
Please view the new features document for complete information.
