When you upgrade to the latest version of SoundCheck, the license is perpetual – in other words, you keep all the new features you have acquired for ever (or until you decide to upgrade to an even newer version). Please ask us if you have any questions about upgrade licensing!
SoundCheck® 20 offers new features for multi-channel and room acoustics, as well as many usability upgrades including:
- Enhanced Perceptual Rub & Buzz: Our new Perceptual Rub & Buzz algorithm is a reliable and repeatable method of detecting audible Rub & Buzz faults on the production line, increasing yield by rejecting only devices with audible distortion defects.
- New Multichannel RTA functionality: The multichannel Real Time Analyzer now displays multiple channels simultaneously, and offers real time calculation and display of channel addition, subtraction, maximum, minimum and power average.
- Updated Signal Generator: A complete overhaul of the signal generator brings additional functionality and simplified operation, particularly when using wav files.
- POLQA: The optional POLQA (Perceptual Objective Listening Quality Analysis) module brings POLQA analysis right into SoundCheck, for perceptual measurements of speech degradation in communications applications ranging from telephones to smart devices.
- Batch Processing of external files: External data files can now be batch-loaded and processed. This enables testing of a large number of external data files to be automated via a sequence, for example wav files of speech recordings.
- New Features for Communications Testing: New stimulus steps and post-processing capabilities such as a silence stimulus step, and RMS level versus time and histogram post-processing steps support communications testing needs, for example, measurement of Doubletalk and other speech transmission parameters.
- Stimulus editor upgrade: The stimulus editor can now create a stimulus from any waveform in the memory list and equalize and adjust its level, for example using active speech level. This enables such adjustments to be made to externally acquired test signals, such as those imported into SoundCheck via TCP/IP or recall steps.
- Saving Multichannel Wav files: It is now possible to export multiple SoundCheck recorded waveforms to a single multichannel wav file.

SoundCheck 20, Listen’s flagship audio analysis software, introduces a new state-of-the-art perceptual distortion algorithm for end-of-line testing – Enhanced Perceptual Rub & Buzz. It also includes a host of new features for multichannel and communications testing, increasing its capabilities for audio measurement of smart speakers, infotainment systems, headphones and hearables, and other voice-activated and multichannel devices.
The new enhanced Rub & Buzz algorithm is a reliable and repeatable perceptual method for detecting audible Rub & Buzz faults on the production line. This offers manufactures the option to increase yield by rejecting only those devices with audible distortion defects. Based on the sound psychoacoustic principles used in Listen’s industry-standard 2011 perceptual algorithm, new research offers refinements that improve listener correlation and new, patent-pending, noise reduction technology offers unrivaled repeatability and reliability for end-of-line use. In fact,this algorithm performs like a human ear under normal listening conditions with the background noise of a manufacturing environment! SoundCheck measures perceptual Rub & Buzz using the same stepped sine wave, simultaneously with other end-of-line measurements, enabling this valuable analysis to be added to production line tests with no extension in test time.
Two of SoundCheck’s virtual instruments, the multichannel RTA and the Signal Generator, have been significantly upgraded. The multichannel Real Time Analyzer now includes expanded functionality for real time observation of audio signals. It displays multiple channels simultaneously, and offers real time calculation and display of channel, subtraction, maximum, minimum and power average. Applications for this new feature include real-time observation of active noise cancellation, automotive industry standard 6-microphone array infotainment measurements, validating headphone seal on a test head prior to measurement by comparing left and right earphone response, and more. RTA curves are now seamlessly integrated with SoundCheck’s standard graphs and can be dragged and dropped into any graph for easy comparison to limits and reference curves. This is useful for quick comparisons to reference standards or golden units, tuning automotive infotainment systems, and more.
An overhauled signal generator brings additional functionality and simplified operation, particularly when using wav files. In addition to standard audio stimuli (sine, white noise, pink noise, etc.) with user-selected sampling rates and resolution, it can play any wav file, any memory list file, and any complex waveform created by the stimulus editor. The level can be referenced to Peak, dB or RMS. The signal can be equalized in real time, and custom EQ curves applied, which is useful when using a non-flat source such as a mouth simulator. A specific portion of a waveform can be selected to play, either by selecting a start and stop time in seconds, or by examining the waveform, and signals can play for a fixed duration, a fixed number of times, or in a continuous loop. Outputs from 2 or more signal generators can be mixed on the same channel, and waveforms from multiple signal generators can be synchronized, or delayed for phase control during playback.
The optional POLQA (Perceptual Objective Listening Quality Analysis) module brings Opticom’s POLQA 3 algorithm, implementing the ITU-T P.863 standard, right into SoundCheck, where it can be used for perceptual measurements of speech degradation in communications applications ranging from telephones to smart devices. Used just like any other analysis step in a sequence, this is a fast and cost-effective alternative to a panel of human listeners. In addition to speech degradation measurements, it may also be used to assess the impact of noise reduction algorithms, evaluate bluetooth degradation due to packet loss, or to analyze distortions introduced into the audio path.
Several new features expand the software’s post-processing capabilities for testing communications devices. These include batch processing of external files, a silence stimulus step, and RMS level versus time and histogram post-processing steps. A pre-written test sequence for categorizing Doubletalk performance to two international standards, ITU-T P.502 and ETSI TS 126 132 (part #3114), from communications expert John Bareham, is also available. Other enhancements include a stimulus editor upgrade, the ability to export multiple SoundCheck recorded waveforms to a single multichannel wav file and a hardware reset option for quickly changing audio interfaces or restoring hardware to a known configuration.
