SoundCheck Version 9.0 Released
Listen, Inc, announces the launch of SoundCheck® 9.0, the latest version of its popular PC and SoundCard based test and measurement platform. It offers a host of new features designed to offer ease of use, increased measurement accuracy, and simpler analysis and presentation of data.
SoundCheck 9.0 is designed for full compatibility with Ampconnect and SoundCheck ONE, Listen’s new integrated hardware box and low cost production line test system. This facilitates global standardization on SoundCheck, as users with SoundCheck 9.0 can view results and analyze data from production lines running SoundCheck ONE. With the appropriate hardware, SoundCheck 9.0 can also be operated in SoundCheck ONE mode to replicate production line test configurations. The software offers full control of AmpConnect (a single hardware box that replaces a power amplifier, microphone power supply, impedance box and digital I/O card in your testing setup) either via the sequence editor or directly via a control panel that replicates the appearance of the front of the hardware.
With a goal to offer even more accurate test results, SoundCheck 9 offers several algorithm refinements. Most notable is the improved Loose Particle Algorithm which offers better noise immunity in production and other noisy environments as limits float with the normalized background noise rather than being set absolutely. In addition to simplifying limit setting, false rejections due to sudden increases in background noise are less likely. There is also now a setting for choosing a maximum stimulus frequency, above which the loose particle envelope is not calculated. As loose particles tend to present themselves during the low frequency portion of a stimulus sweep, this feature further prevents false rejects.
SoundCheck aims to improve measurement accuracy by minimizing the potential for operator error. Version 9.0 includes a TSR Algorithm Maximum Harmonic Indicator which alerts the operator if the selected combination of window size and speed will cause individual harmonics to be inaccurately calculated. Also, both the Stimulus and Limits Editor menus now offer two views, basic and advanced. The basic views feature only the commonly adjusted settings, and by clicking on the advanced tab, many more are revealed. This keeps operation simple for novice and production line users while retaining the flexibility demanded by R&D applications.
Post-processing and data presentation also offer enhancements in this new release. Curve smoothing with Nth octave resolution is now built into the analysis editor. This means that even where large volumes of data need to be collected for analysis purposes, this can be reduced after the calculations have been made to accelerate post-processing, reduce data to a common resolution to compare algorithms, and produce smoother curves for data sheets and other marketing materials. To further help with data presentation, several DAT files can now be opened at once from the Memory List. This is convenient when running statistics on a batch of curves and working with large numbers of files.
