SoundCheck 18.1 is now available. This update to version 18 includes a couple of new features and several bug-fixes. It introduces control for the upcoming AmpConnect 621 interface, an all-in-one multichannel interface (6-in, 2-out) that is exclusively controlled via the software for seamless integration with test sequences and virtual instruments. It also includes the new Auto Delay+ algorithm for increased accuracy of open loop measurements, especially in cases where the delay is longer than 1 second. It is particularly useful for measuring smart devices such as smart speakers, automotive audio, hearables, etc., where test signals are sent via the cloud. In addition, there are several bug fixes. Version 18.1 is available free of charge to all owners of version 18. If you have not received a download link from your sales engineer, please contact us.
Our series of instructional training videos continues with this series of 4 short videos explaining Statistics. These introduce the user to the statistics options in SoundCheck, and demonstrate how to use them in 4 different ways: in sequences, with results, Process Capability measurements, and offline statistics.
In this 2 hour training, we will be taking a deeper dive into some of the more advanced features of the analysis editor. This will be useful for anyone with a basic understanding of SoundCheck setup, calibration and sequence writing who is looking to add value to their measurements by optimizing their test procedures. We will be taking a closer look at how to configure various analysis algorithms, and the impacts of the chosen settings on measurement confidence and speed. This training offers value to both R&D and production users. We will cover:
- Understanding and configuring the distortion options in SoundCheck’s Harmonictrak algorithm, including how to select the best option for your application
- Configuring the Loose Particles algorithm to detect transients in waveforms to catch manufacturing defects that may not be highlighted using frequency based analysis
- Using SoundCheck’s measurement confidence option to adjust the stimulus to obtain the best trade off between speed and accuracy
- How to analyze ‘real world’ test signals (e.g. multitone, noise, music, speech) for measuring devices that do not perform well with sine wave signals (e.g. telecoms, those including DSP)
This training is free to support contract holders and $79 for others.
Sept 17, 2020. 9.00am and 2.00pm US East Coast time (6.00 am and 11.00 am West Coast time)
In this 60 minute online seminar, Listen’s Technical Support Manager, Steve Tatarunis discusses Microphone Measurement Basics.
Listen, Inc’s SoundCheck electroacoustic test system is used by the world’s leading OEMs and their contract manufacturers on thousands of production lines worldwide. Although it can be used for testing a wide range of devices including speakers, microspeakers, headphones, headsets, smart devices, cellphones and more, this seminar will focus on microphones.
In this online session, Steve Tatarunis will cover the basics of microphone testing, including:
- Common microphone types and how they work
- Microphone specifications
- How to measure microphones using the two standard methods available in SoundCheck
- Substitution method
- Equalized speaker method
- R&D and production test environments
- Important measurements such as frequency response, sensitivity, etc.
There is no charge for this seminar, but registration is required. Please sign up below. Note that you will be sent login details the day before. The same login details will offer access at both times, so you can choose to attend the one most convenient to you.
The ability to quickly generate test sequences is one of the most powerful SoundCheck skills you can acquire. We are bringing a 2 hour basic sequence writing course to the comfort of your own home with our new online training at a convenient time for our European customers.
This 2 hour course is a condensed version of the basics of sequence writing from our popular 2 day training class. We will start from the beginning, explaining how to determine the test parameters and hardware that will meet your specific test requirements. We will look at best practices for creating a sequence, and finally we will assemble a sequence from scratch. This course is ideal for novice SoundCheck users, or those who have been using SoundCheck with sequences that others have written and who are ready to start developing their own. This training is free to support contract holders and US $79 for others.
Following questions from some SoundCheck users who had watched #3 in this series (sequence optimization), Steve Tatarunis takes a look at the measurement confidence function in SoundCheck, and explains the trade-offs between speed and accuracy when choosing a step size to optimize your measurement.
Anastassia Tolpygo demonstrates some neat features of virtual instruments that you may not have seen before. These enable you to make a quick distortion measurements, accurately measure frequencies at very high resolution, and plot and save curves over time using just the virtual instruments without the need for a sequence step.

In this short video, Steve Tatarunis takes a deeper dive into the Offline Statistics functionality in SoundCheck, demonstrating how you can run statistical analyses from home on data from your production facility or overseas contract manufacturer. No hardware required – just your computer with SoundCheck and some measured data!
While you are working from home, optimize your SoundCheck sequences by tweaking your limits for optimum quality and yield. Devin Vaillancourt explains the different types of limits available (absolute, floating, aligned, and more), and once you have explored the different types, you can test out different limit configurations using saved data from products that you have already measured.
