Listen Releases SoundCheck 17: New Features for Multichannel and Voice-Controlled Testing

Save to MATLAB

Listen is excited to announce the release of SoundCheck Version 17. This new Windows/Mac release offers many features to simplify multi-channel and voice controlled testing, such as a new level and cross-correlation trigger, average curve/waveform post-processing functionality, the ability to easily read and work with multichannel wavefiles, multiple DC Connect control, and enhanced database options. On the usability side, SoundCheck 17 offers increased flexibility in color pallets, save to MATLAB option, and the ability to recall CSV formatted text files.

Today’s modern audio devices have two important testing requirements: the ability to test a voice activated device with no analog input, and the ability to control and test multiple channels simultaneously, for example, microphone or speaker arrays. SoundCheck 17 contains a host of new features to facilitate this. For voice-activated measurements on devices with no analog input, such as smart speakers, wearables, hearables and smart home devices, the new level & cross-correlation ‘smart trigger’ offers improved performance. By using a chirp-based conditioning tone and searching for the exact log sweep frequency, it is more robust and less susceptible to false triggers than simpler level and frequency triggers.

To save time when testing smart devices where it is necessary to test microphone or speaker arrays, SoundCheck 17 can now directly read multichannel WAV files from the memory list, signal generator and stimulus steps. Also for testing multi-channel arrays, multiple DC Connects can now be controlled, independently configured, and used for data acquisition within SoundCheck. The new Average Curve/WFM post processing function which allows the average curve (or waveform) of a selected group of data in the memory list to be obtained, is particularly useful for power averaging selected curves, averaging curves from different spatial positions (e.g. microphone arrays), and complex averaging of multiple measurements with background noise. Finally, the database module has been enhanced and is now it 4x faster and 3x more space-efficient than previous versions. This is particularly important for testing modern audio products with multiple transducers (microphone arrays, multiple speakers, etc.), as these often generate large volumes of data.

New Level and Cross-Correlation Trigger

Usability enhancements include improved color pallets which offer ultimate flexibility in defining colors for backgrounds, grids, cursors and graph lines. New default color palettes are included, and user-defined palettes can be saved as pre-set files which will be applied to any new display created. Multiple palettes can be saved, for example allowing different color sets for different applications. In addition, SoundCheck can now save any data (including memory list curves and Soundmap (time frequency analysis) data ) to  MATLAB for additional processing. Data is saved as a standard MAT file and can be manually or automatically saved in this format.

Additional new features include support for the new APTX HD codec for high resolution Bluetooth testing, a 64 bit Demo / Data Viewer which enables measured data to be recalled and viewed without the need to own a separate license, and the ability to recall CSV files as well as TXT files.

Listen offers ETSI Standard background noise generation system

Listen offers ETSI Standard background noise generation system

Listen, Inc. has launched the ETSI standard background noise generation module, a SoundCheck test sequence which calibrates a 4.1 speaker array to conform with the ETSI ES 202 396-1 Standard. This provides an equalized, calibrated playback solution to stress devices in a standardized and repeatable way. The sequence includes a library of real-world binaural recordings from the ETSI standard: cafeteria, pub, crossroad, vehicle, single voice distractor, and office noises.  Custom or user-defined binaural recordings can also be used. With a purchase price of just $5,000 for the test sequence, this offers an extremely economical alternative to a conventional $20,000+ stand-alone background noise generation system.

Furthermore, it offers the advantage that the ETSI standard library is fully integrated with, and managed by, the SoundCheck test system. This means that the calibrated background noise levels can be fully controlled and adjusted as part of a pre-programmed test sequence, significantly reducing test development time as well as simplifying the physical setup.

This has many applications, for example evaluating ANC, noise suppression, SNR optimization of microphone arrays, beamforming directionality studies, and more. It is particularly useful for voice recognition testing as the test sequence may include loops to incrementally increase the volume or change the noise and repeat the test until the voice is no longer accurately recognized.

SoundCheck 16.1 Released – New Frequency Trigger for Open Loop Testing

Listen is excited to announce the release of SoundCheck 16.1. This minor release, which contains some exciting new features, is available free of charge to all registered users of SoundCheck 16.0.

Most significant is the inclusion of a new frequency trigger. This allows frequency-based triggering of acquisition from an external source using a pilot tone at the beginning of a test sweep. This allows for improved accuracy over previous level-based triggering when capturing responses from a device where you don’t have direct access to the microphone or speaker, especially in noisy environments. This technique optimizes open loop test methods for smart speakers and other voice-controlled devices such as smart phones, robots, automotive audio, smart thermostats, hearables and more. You can view a short video explaining this feature here:

 

We also have a free measurement sequence using the frequency trigger that can be downloaded from our website so that you can test it out right away! View Sequence.

SoundCheck now also fully integrates with the Mentor A2B interface for testing automotive audio connected via the Analog Devices A2B digital bus. The Mentor Analyzer, which handles the transmission of signal in to and out of the bus, is viewed as an ASIO interface by SoundCheck, enabling SoundCheck to read/write to the device and therefore analyze any transducer connected to the A2B bus. A custom VI permits control of the Mentor A2B interface configuration via SoundCheck. This means that it can be controlled from within a SoundCheck sequence, for example loading configurations and starting/stopping ASIO streams. This makes it an ideal R&D or production line test solution for automotive audio, or for anyone testing transducers connected via A2B bus. More.

Also available (additional cost) with this new release are two optional sequences – background noise simulation to the ETSI ES 202 396-1 standard, and the TIA-920B dual-bandwidth telephone test standard.

The background noise simulation sequence (part number 3121) is a cost-effective alternative to dedicated background noise generation systems. It calibrates a 4.1 speaker array to conform with the ETSI ES 202 396-1 Standard, providing an equalized, calibrated playback solution to stress devices in a standardized and repeatable way. The sequence includes a library of real world binaural recordings from the standard, and custom or user-defined binaural recordings may also be used. Applications of this sequence include evaluating ANC, noise suppression, voice recognition testing, SNR optimization of microphones, beamforming directionality studies of microphone arrays and more. More.

The TIA-920B sequence (part number 3111) tests to the TIA-920B dual-bandwidth standard that applies to both narrowband (NB) and wideband (WB) devices. It also allows a choice between Free Field (FF) and Diffuse Field (DF) as the Listener Reference Point (LRP). The current release measures digital communications devices with handset features, according to TIA-920.110-B and speakerphones, according to TIA-920.120-B. Support for headset measurements, according to TIA-920.130-B will be added in a future release. More.

SoundCheck ONE for headphone testing

seq_SC-ONE_headphones_display_and_memory_listWe are excited to announce a new low-cost headphone test package – SoundCheck ONE for headphone testing (part # 1007). This includes SoundCheck ONE, a basic version of the SoundCheck software, along with AudioConnectTM, an audio interface with built-in headphone amplifier. Only a headphone coupler or test fixture and associated power supply is additionally needed to make up a complete headphone test system. The SoundCheck ONE headphone test sequence carries out all basic headphone measurements such as  frequency response, sensitivity, THD, Rub & Buzz, Perceptual Rub & Buzz, loose particles, polarity and channel balance. It can be easily customized and saved for specific products by turning individual measurements on and off, and by adjusting settings within each sequence step such as stimulus range and level, tolerance limits, graphical displays, and data saving. It is an excellent low-cost entry level system, ideal for those on a tight budget.

Please note that although the SoundCheck ONE Headphone test sequence cannot have steps added/removed or the layout modified, customers may upgrade to a SoundCheck package that supports this at any time in the future, should testing needs expand to require additional functionality. Listen can also offer the GRAS 45CC headphone test fixture along with a SoundConnect 2 power supply for a complete production line test system.
