This training video provides an overview of how to create and use custom VIs. Custom VIs enable you to extend the capability of your SoundCheck system by
- Programming your own highly customized tests which run within Soundcheck,
which is useful if your device requires additional specific tests that fall
outside of the SoundCheck test suite
- Enabling SoundCheck to control other hardware devices and use them in test
sequences, for example additional application-specific interfaces.
Note that the method is slightly different in SoundCheck version 16 and later versus version 15, so please view the video that corresponds to your SoundCheck installation.
This series of 5 training videos explains how to use sequence loops and logic. Sequence loops and logic are extremely powerful features that can significantly reduce the time taken both to program and run tests. The first video walks you through the basics, then the following videos focus on 4 examples: Loop Stimulus Level, Polar Plot Measurements, Jump To Sections and Digital I/O.
Sequence Loops and Logic 1: The Basics
Sequence Loops and Logic 2: Loop Stimulus Level
Sequence Loops and Logic 3: Polar Plot Measurements
Sequence Loops and Logic 4: Jump To Sections
Sequence Loops and Logic 5: Digital I/O
These 3 training videos provides guidance on how to use message steps in sequences. Message steps enable dialog between the sequence and either the operator or external devices. These fall into 3 categories, each with a short instructional video.
Part 1 – Operator Message steps
– messages between the sequence and operator, for example to advise the operator to do something, or to request the operator input a value or yes/no input.
Part 2 – External control messages
– messages that enable communication with external hardware such as DIOs and RS232 devices.
Part 3 – Listen Hardware Control messages
– messages that enable control over Listen and Portland Tool & Die hardware.
These 5 short tutorials guide the user through the various tabs in the SoundCheck analysis editor. Note: The next tutorial will cover the remaining tabs and the available analysis algorithms.
In this short video, sales engineer Les Quindipan gives a brief overview and demonstration of the new features and functionality of SoundCheck 17, including the new level and cross-correlation trigger, average curve/waveform post-processing functionality, new color palettes, save to MATLAB option, and more.
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 palettes, 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.
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.

Wednesday May 1st & Thursday May 2nd.
Instructors: Mark Latshaw (Listen, Inc.), Steve Temme (Listen, Inc.), Introduction from Michael Trolle (Vibrakustik)
In this class, we start with the basics – how to set up your system, calibrate your hardware and use the virtual instruments. We then focus on how to develop and modify test sequences, starting with stimulus, analysis and display options, and progressing to more advanced functionality such as sequence loops and jumps, statistics, and advanced post-processing. The class is a combination of classroom-style teaching and hands on practical sessions, so that when you leave the class you will be ready to go in practice as well as in theory.
This hands-on class covers all the major features of SoundCheck, including writing sequences, test signals, analysis, distortion measurements and more. The class is a combination of presentations interspersed with hands-on exercises to ensure that you are comfortable with all the concepts and methods taught before you leave the classroom. Although no previous SoundCheck experience is assumed, the course still offers plenty to users familiar with writing basic sequences. Content includes:
- Overview of SoundCheck software
- Software Options
- Configuring audio interfaces and external equipment
- Listen Certified Sound Cards
- Calibration of different DUT types (telephones, speakers, etc.)
- Virtual instruments
- Spectrum Analyzer, RTA, Multi-meter, Signal Generator, Oscilloscope
- Virtual Instruments – hands-on
- Online forum, bug and wish lists
- SoundCheck Steps & Sequences
- Philosophy & Architecture
- Creating and editing SoundCheck Test Sequences and Steps
- Using the Sequence Wizard
- Stimulus & Acquisition Step details
