SoundCheck 17 Discounted Upgrade Pricing
For a limited time we are offering deep discounts on a system upgrade to enable you to get up to date with the latest version of SoundCheck. The upgrade offer is a simple flat rate: $3,950 for owners of SoundCheck 11 or 12, $3,250 for owners of version 13, $2,500 for owners of versions 14 through 15, and $1,395 for owners of version 16. All the modules on your present system will be included.
SoundCheckTM 17’s feature-packed release offers many features to simplify multi-channel and voice controlled testing, as well as many usability upgrades including:
- Improved color pallets for ultimate flexibility in defining colors for backgrounds, grids, cursors and graph lines.
- Save to MATLAB – All data including memory list curves and Soundmap (time frequency analysis) data can now be saved to MATLAB for additional processing. Data is saved as a standard MAT file and can be manually or automatically saved in this format.
- A new Level & Cross-Correlation Trigger (requires optional module 2006 – Time Selective Response) for improved performance for open loop measurements
- An enhanced database (optional module) is now 4x faster and 3x more space-efficient than previous versions, making it an extremely powerful data management tool for customers testing modern audio products with multiple transducers (microphone arrays, multiple speakers, etc.), as these frequently generate large volumes of data.
- SoundCheck can now read multichannel WAV files directly from the memory list, signal generator and stimulus steps, simplifying the testing of multichannel devices such as microphone or speaker arrays
- SoundCheck can now control multiple DC Connects which can be configured independently
- A new Average Curve/WFM post processing function allows you to obtain the average curve (or waveform) of a selected group of data in the Memory List.
- SoundCheck now supports the new APTX HD codec for high resolution Bluetooth testing
- A 64 bit demo / data viewer replaces the 32 bit demo version. When the software key is not installed, previously measured data can still be recalled and viewed.
- CSV formatted files can be recalled in addition to TXT files.
Call your sales engineer today to receive a quote for upgrading all your SoundCheck systems. These discounted rates have been extended until June 7th, 2019 but will not be available after that, so please get your order in soon!

AISE, Orlando, FL, Jun 9-10, 2019
This years AISE (ALMA International Symposium & Expo) will be held on June 9-10 in Orlando, FL. Listen will be showcasing its suite of audio measurement equipment for measuring smart speakers, wearables, smart home audio, hearables and automotive audio, as well as conventional transducers such as loudspeakers, headphones and microphones.
In addition to exhibiting, Steve Temme will present a half-day seminar on smart speaker testing. This informative and educational seminar will discuss the challenges of testing smart devices such as smart speakers, smart home devices, wearables and more, and demonstrate various methods of testing such devices. Steve Temme will also present a paper on testing smart hearable devices, and Les Quindipan will demonstrate automotive audio testing using the Mentor A2B interface with SoundCheck.
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.
Seminars in China: Smart Speakers and Automotive Audio
The Challenges of Testing Speech Controlled Audio Systems
Your devices got smarter. Did your test system?
Learn how to implement open loop tests for both playback and recording in a range of devices including smart speakers, automotive audio, robots, IoT devices and more in this practical seminar.
Open loop testing (testing devices where inputs and outputs are independent) enables many types of smart devices and their components to be tested in various formats and situations including:
- Smart speakers, smart watches and other smart devices
- Microphone arrays
- Speech recognition systems with microphones
- In-vehicle audio systems
- Audio devices/systems with no physical inputs or outputs
- Testing in noisy environments
We explain how to measure the same parameters as traditional loudspeakers, discussing such challenges as injecting and extracting response signals, time delays, and triggering the system using voice commands. We also demonstrate how to measure microphone array performance, speakerphone performance and more. Course content includes:
- Stimulating and capturing responses from a device where you don’t have direct access to the microphone or speaker (open loop testing).
- Delays, asynchronous stimulus / acquisition, and working with the ‘cloud’
- Testing with real world signals such as speech and music, and how to analyze results from these test stimuli
- Voice Recognition – key word spotting, wake word testing, directionality, and the effect of background noise on voice recognition performance
- Telephony – testing smart speakers for hands-free calling
Speakers /主讲人: Steve Temme, Listen, Inc. and Peter Wulf Andersen, GRAS.

Free Seminar: Smarter Measurements for Smarter Speakers! Instructor Steve Temme (Listen, Inc.)
Learn how to test smart speakers, hearables, watches and other wearables, robots, smart home devices, automotive entertainment systems and other smart devices in our practical half-day seminar taught by industry expert Steve Temme of Listen, Inc.
Although acoustic testing of smart speakers and other voice-activated devices presents challenges such as injecting and extracting response signals, time delays, and triggering the system using voice commands, it is still possible to measure the same parameters as traditional loudspeakers, In addition we can also measure microphone array performance, speakerphone performance and more.
We demonstrate how to do this, focusing on:
- Stimulating and capturing responses from a device where you don’t have direct access to the microphone or speaker (open loop testing).
- Delays, asynchronous stimulus / acquisition, and working with the ‘cloud’
- Testing with real world signals such as speech and music, and how to analyze results from these test stimuli
- Voice Recognition – key word spotting, wake word testing, directionality, and the effect of background noise on voice recognition performance
- Telephony – testing smart speakers for hands-free calling
There is no charge for this seminar and lunch will be provided.
