Why Standardize on SoundCheck for Production Audio Test?

SoundCheck is used on thousands of audio production lines worldwide. This brief introduction outlines some of the reasons why so many of the world’s top audio companies have standardized on SoundCheck. These range from seamless factory integration to the world’s most advanced audio measurement algorithms.

Turnkey System – Quick setup. Compatible with existing hardware.

Selection of audio interfaces suitable for production line audio testListen’s SoundCheck software and audio test hardware work together seamlessly to expedite installation and configuration. ‘Plug-and-play’ setup and TEDS compatibility minimize configuration time, particularly with multichannel interfaces. The correct authorization key can be automatically loaded from a network location so a single computer image can be created rather than individually configuring each computer. This results in significant time savings when deploying SoundCheck across multiple test stations.

Should you choose to use alternate hardware, Listen’s software is compatible with a wide range of audio interfaces as well as microphones, couplers, amplifiers and other accessories from many different manufacturers.

Not only is SoundCheck quick to set up – it is also simple to use with automated or one-click operation and clear visual pass/fail signals. Various operator access levels enable the system to be ‘locked’ to avoid accidental modification of tests, and Listen’s newest hardware has no control panels on the device itself, making it impossible for test and device settings to be accidentally changed.

Seamless Factory Integration – TCP/IP and Python control. Full database compatibility.

SoundCheck can be fully controlled using LabVIEW, Test Stand, Python. C#, Visual Basic or any programming language that can communicate via TCP/IP. Multiple test stations can be controlled by a single computer.

In addition to controlling SoundCheck, data can also be passed to or from SoundCheck via TCP/IP while a sequence is running. This enables test parameters, such as limits, test levels, and test signals, to be stored externally so that a single sequence is used for multiple products. This simplifies test configuration and reduces the number of sequences that a large organization needs to maintain. Additional hardware or equipment can also be controlled from within SoundCheck using LabVIEW VIs or python code. This might be used for sending commands to a device under test, or controlling automation equipment such as bar code readers.

SoundCheck’s integration capabilities extend to saving data. SoundCheck includes extensive built-in statistics functionality and multiple data saving options. It also offers the option of automatically saving measurements to any standard or custom SQL or Microsoft Access database for full traceability and more detailed data analysis. Measurement results can even be accessed via TCP/IP, enabling customized programs to be written to collect specific data. Once test results are saved in a database, industry standard tools can then be harnessed to run analytics over large data sets. A plugin is available to transfer data to the popular WATS test data management platform.

Cutting Edge Perceptual Algorithms–Maximum yield. 100% audible fault detection.

Screenshot of ePRB results - a valuable algorithm for production line audio testSince SoundCheck was launched in 1995, cutting-edge research-driven algorithms have been our strength. Many of the test methods that we developed in the 1990s and 2000s are now the widely accepted industry standard (e.g. Stweep, Harmonictrak, Higher order harmonic distortion for Rub & Buzz detection, normalized distortion, open loop testing, log chirp for time-windowed measurements and more). We’ve continued to innovate, focusing on methods that are fast and accurate, even in noisy production environments.

In recent years, we have led the way with the development of perceptual distortion measurement algorithms. Our enhanced Perceptual Rub & Buzz and enhanced Loose Particle algorithms accurately and repeatably detect manufacturing-induced harmonic and transient distortion with excellent noise immunity and correlation to audibility. Furthermore, they are extremely simple to set limits compared to other methods.

Full Test Control–Test to your specification, even at your contract manufacturer.

Sequence Protection setup for production line audio testSequence Versioning configuration for production line audio testSoundCheck sequences are easy to share via email both internally and with manufacturing partners. SoundCheck also provides unique options to guarantee test integrity especially when using contract manufacturers.

Sequence Protection enables sequences to be locked and protected with a password. This prevents modification and conceals the test details for complete test confidentiality and security. Test sequences can also be locked to specific SoundCheck serial numbers, to ensure that all measurements are being made on legitimate SoundCheck systems. Sequence versioning allows complete, annotated, tracking of any sequence modification. This helps ensure that your manufacturing facility is always using the latest, or approved version of a test sequence.

Cost– Competitively Priced – more affordable than you think

Our modular pricing structure means that you can purchase just the functionality you need for production test, and are not stuck paying for features that you’ll never use. This makes SoundCheck one of the most competitively priced test systems of this caliber available.

That doesn’t mean you are stuck with a basic system. SoundCheck is infinitely upgradable. If your test needs change over time, you can simply add-on additional modules. Similarly, if we later introduce new functionality that would add value to your test setup, version upgrades are easy and competitively priced. This makes a SoundCheck system very versatile, particularly for contract manufacturers who fabricate a variety of different audio products, each with their own test requirements.

Naturally production configurations are based on exactly the same advanced algorithms as our R&D systems, and the two versions are 100% compatible. This makes it easy to transition R&D tests to the production line, or for a manufacturing facility to share test data with their R&D department for additional analysis or to help with troubleshooting.
