SoundCheck

The SoundCheck software is the heart of Listen’s test system. In addition to its powerful analysis capabilities, it controls and communicates with audio interfaces and all brands of measurement hardware, and includes all the stimuli, algorithms and analysis functionality needed to develop and run virtually any audio test. Software-based since its inception in 1995, it combines the power and flexibility needed for R&D applications with the speed and noise immunity demanded by high throughput production lines. The software is modular, enabling a system to be tailored for your specific measurement needs and budget constraints, with easy upgrades should your needs change.

Wide-ranging measurement capability in one platform
SoundCheck isn’t limited to one type of measurement. It supports an extensive set of acoustic and electrical tests in both the frequency and time domain, including both traditional and perceptual measurements. Likewise, it is device agnostic, handling both wired and wireless measurements on speakers, headphones, microphones, automotive infotainment systems, communications devices, hearing aids, smart devices and more. This means that you don’t need multiple tools or platforms; SoundCheck offers a unified environment for testing all your devices.

Modular structure for flexibility and customisation
The modular approach means you can select the software modules you need while not paying for unnecessary functionality. This makes it easy to standardise on SoundCheck throughout your organisation: different configurations for different products or test specs, yet a common platform to facilitate compatibility, training and resource flexibility.

Hardware Agnostic
SoundCheck is designed to work with audio interfaces and test hardware from a range of manufacturers. In fact, when Listen launched in 1995, SoundCheck was the only measurement system designed this way. This gives you the flexibility to choose your own hardware, and lets you use measurement accessories you already own to minimise overall system cost.

Unrivalled test flexibility
You can configure any test you want from a series of steps, change virtually every parameter of any test step, and build your own test steps entirely from scratch. Any stimulus signal can be created or imported, and any custom equation can be added to SoundCheck and used in data analysis. Deep analytics and the ability to process and re-process data provide valuable measurement insights, both in the R&D lab and on the production line. While other test systems restrict you to the tests that they want you to make, SoundCheck offers complete flexibility to program your own. Listen also provide over 100 free pre-written test sequences to enable you to get up and running fast. These cover both basic and advanced tests for a range of measurements and applications, and may be customised or used as a springboard for your own test development.

Although Soundcheck handles complex lab measurements with ease, it’s also production-line ready. Advanced algorithms ensure speed and noise-immunity, and repeatable, automated tests provide consistency. Full traceability is maintained through database integration, and advanced control via TCP/IP ensures easy control and data transfer with all factory automation systems. Test sequence control facilitates close partnerships between your engineering and manufacturing teams, preserving your intellectual property and ensuring test integrity.

Designed by engineers, for engineers
Every aspect of SoundCheck – its modular structure, flexible test development and extensive hardware options – helps you build exactly the tests you need, not just the ones someone else imagined. Listen is committed to ongoing innovation, regularly adding new features and measurement methods through optional (but never required) software updates.

Whether you’re characterising a new transducer, benchmarking performance across product lines, or ensuring consistency in global production, SoundCheck provides the measurement tools you need to make better sounding products.

Applications

While SoundCheck measures anything that makes sound, common applications include:

• Loudspeakers and microspeakers
• Headphones and headsets
• Microphones and microphone arrays
• Smart devices
• Automotive audio
• Communications
• Hearing Aids
• Audio Electronics
• Haptic Devices

Measurements

SoundCheck measures numerous fully configurable parameters right out of the box and can display numerical and graphical results based on any custom calculation of stimulus and response signals in the time or frequency domain. Capabilities include:

• Fundamental Electroacoustic Measurements
  • Frequency Response
  • Distortion (THD, Rub & Buzz, IMD)
  • Phase
  • Impedance
• Advanced Electroacoustic Measurements
  • Polar plots
  • Thiele-small parameters
  • Simulated Free Field e.g. Splice near field to time-windowed far field
  • Time-frequency analysis
  • Transient detection

• Max SPL

• Psychoacoustic measurements
  • Perceptual distortion
  • Masking curves
  • Spatial audio measurements
• Measurements to international standards
  • Loudness e.g. Zwicker, ITU
  • Communications e.g. IEEE, TIA, ITU, ETSI, POLQA
  • Hearing Aid e.g. ANSI, IEC
  • Headphone e.g. EN50322
  • Loudspeaker e.g. AES75, IEC/CEA

And many more. The ability to create any custom analysis via the application of custom steps and formulae to measured data means that SoundCheck is unlimited in the analyses it can implement.
