SoundCheck 18 New Features

Check out our short demo video for a brief introduction to all the new features in SoundCheck 18. These new features in SoundCheck 18 focus on automation and simplicity. Automation features include the ability to pass test configuration data to and from external programs, and control of MEMS interfaces via a sequence. Setup and test development is simplified with ‘plug and play’ functionality for Listen hardware, simplified gain control, and improved sampling rate management.

Soundcheck’s new sequence parameter feature allows the user to pass test configuration data into the memory list from external programs using TCP/IP commands. By externally storing parameters such as limits, test levels, and test signals, a single sequence can be used for multiple products. Improved hardware setup enables you to plug in and make measurements faster. Listen and Portland Tool & Die Hardware are now true ‘plug-and-play’ which minimizes configuration time, particularly with multichannel interfaces. Simply connect your AmpConnect, BTC-4149 or other Listen interface via the USB cable and the software auto-populates parameters such as sampling rate and calibration values, and creates input and output signal paths. Multiple hardware items are stored within the software, so that they are immediately recognized when connected, and the software will automatically default to the correct device. Auto read and auto range gain settings are now easily accessible as drop-down options in the gain menu in the acquisition step editor, and auto-read is available in virtual instruments. When the gain is set to auto range, SoundCheck will automatically identify the correct level of gain to optimize the measurement signal to noise ratio.

For any hardware device, the user can specify the latencies for various sampling rates, either by entering them manually or importing from a file, and SoundCheck will automatically use the correct latency for any sampling rate specified in the stimulus editor. Digital I/O control is now a separate message step, which means that all controls for I/O settings are completely separate from other AmpConnect settings, minimizing the possibility of other parameters being changed on accident. The Portland Tool & Die MEMS microphone interfaces can now be fully controlled from within SoundCheck, offering faster setup and greater measurement reliability. TEDS Support (with compatible Listen hardware) enables automatic identification, configuration and calibration of TEDS microphones and accelerometers, saving time on initial hardware setup and whenever hardware is changed. SoundCheck 18 now includes WASAPI driver support in Windows 10, offering full multichannel support. Finally, the new Auto Delay+ algorithm offers increased accuracy for open loop measurements, especially in cases where the delay is longer than 1 second.
