The New MDT-4000 Turntable

There’s a new turntable in town!

We’re excited to launch the Portland Tool and Die MDT-4000 Turntable, exclusively available from Listen. Designed specifically for audio measurements, it packs a host of usability and safety features, along with high precision and low maintenance in a compact and lightweight package. Features include:

High Precision: The MDT-4000 offers a resolution of 0.1°, one of the most accurate on the market.

Low maintenance: A maintenance-free worm drive requires no lubrication, making this turntable maintenance-free, an advantage when it is remotely located, for example in an anechoic chamber

Easy Set-Up and Operation: The turntable has a built in level, along with 4 adjustable feet, making it quick to perfectly level and align equipment. Clearly visible degree markings provide quick visual confirmation of position and make it easy to align accessories with the turntable. Mounting holes at 3”, 9” and 15” diameter provide a variety of mounting options, and a center cable pass-through prevents tangling. The turntable retains position memory across power cycles, so the display remains synchronized with the actual position, even when the turntable is turned off.

Flexible control options: 4 control options offer ultimate flexibility:

  • USB – easy control for short distances
  • RS232 for longer distances  and backwards compatibility with LT360
  • RestAPI provides long distance communication via LAN, enabling control via a webpage using a laptop or smartphone and enabling custom control applications to be written
  • Full control from within SoundCheck (naturally!)

Packed with safety features: With emergency stop buttons on the front panel and in the software, plus an optional remote button for when the turntable is not within reach, your valuable products and instrumentation are protected. An automatic stall detection mechanism identifies if an obstruction is preventing the turntable from reaching its target position and both warns the user and stops the drive to prevent damage to equipment.

Quiet operation: Silent at rest, and low-noise when rotating, it is ideal for audio applications. Variable torque enables slower rotation speeds to be used for quieter operation when measuring during rotation.

Right-sized: Supports weights of up to 100kg in either compression or inverted orientation, making it suitable for the majority of audio applications. Weighing in at just 12kg, it is easy for one person to move around the laboratory.

Competitively priced: The MDT-4000 is competitively priced with other turntables, and considerably less expensive than others offering the same advanced functionality.

Listen’s new enhanced Perceptual Rub & Buzz algorithm is a reliable and repeatable method of 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 Rub & Buzz algorithm, the new refinements improve listener correlation and demonstrate significantly better noise rejection to offer unrivaled repeatability. The multichannel Real Time Analyzer displays multiple channels simultaneously, and offers real time calculation and display of channel addition, 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. Paired with the AmpConnect 621 multichannel audio interface, it offers unmatched functionality for multichannel measurements on a wide array of devices, especially those featuring dynamic signal processing. RTA curves are now seamlessly integrated with SoundCheck’s standard graphs.

A complete overhaul of the signal generator brings additional functionality and simplified operation, particularly when using wav files. In addition to standard audio stimuli (sine, white noise, pink noise) 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 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. Version 20 extends SoundCheck’s batch processing power with the ability to automatically load and process external data. This is useful in any application where it is desirable to automate the testing of a large number of external data files via a sequence, for example wav files of speech recordings. New stimulus steps and post-processing capabilities support communications testing needs, for example, measurement of Doubletalk and other speech transmission parameters. These include a silence stimulus step, and RMS level versus time and histogram post-processing steps.

A new multi-channel version enables viewing of multiple signal paths simultaneously. Spectrum settings such as gain, octave band, weighting, averaging and time-weighting can be set independently for each channel for complete measurement flexibility. The new Multi RTA also supports a power averaging calculation on the signal paths which can be used for spatial and sound power measurements.

The RT60 Room Acoustics module measures reverberation time and clarity of any room or space. This functionality is useful for quantifying how speaker(s) will interact with the acoustics of a particular type of room. SoundCheck offers extremely fast measurements using a continuous sine sweep with the Log TSR algorithm to obtain the impulse response. The reverberation decay curve is calculated from the backwards integrated impulse response.

SoundCheck now offers the option to operate in WASAPI-exclusive mode. The advanced interface offers superior communication with audio devices in recent versions of Windows, giving SoundCheck greater control over the audio stream. Multiple WASAPI devices may be used simultaneously, and it’s also possible to combine WASAPI and ASIO devices to increase channel availability.

SoundCheck 19 supports AmpConnect 621, Listen’s new high resolution (up to 192kHz) multichannel audio interface, exclusively configured via the SoundCheck 19 software. AmpConnect 621 features full plug-and-play functionality and TEDS support for automatic identification, configuration and calibration of microphones and accelerometers. SoundCheck 19 with AmpConnect 621 is a simple and cost-effective solution for automotive measurements with a 6-microphone array.

The new Diagnostic Window enables the user to suppress warning dialog windows when running a sequence and instead log the errors, warnings, and information in a separate diagnostic window. SoundCheck now allows use of a USB controller knob in both Windows and MacOS to adjust the SoundCheck Signal Generator.

SoundCheck 18 New Features

Check out our short demo video for a brief introduction to all the new features in SoundCheck 18. These new features in SoundCheck 18 focus on automation and simplicity. Automation features include the ability to pass test configuration data to and from external programs, and control of MEMS interfaces via a sequence. Setup and test development is simplified with ‘plug and play’ functionality for Listen hardware, simplified gain control, and improved sampling rate management.

Soundcheck’s new sequence parameter feature allows the user to pass test configuration data into the memory list from external programs using TCP/IP commands. By externally storing parameters such as limits, test levels, and test signals, a single sequence can be used for multiple products. Improved hardware setup enables you to plug in and make measurements faster. Listen and Portland Tool & Die Hardware are now true ‘plug-and-play’ which minimizes configuration time, particularly with multichannel interfaces. Simply connect your AmpConnect, BTC-4149 or other Listen interface via the USB cable and the software auto-populates parameters such as sampling rate and calibration values, and creates input and output signal paths. Multiple hardware items are stored within the software, so that they are immediately recognized when connected, and the software will automatically default to the correct device. Auto read and auto range gain settings are now easily accessible as drop-down options in the gain menu in the acquisition step editor, and auto-read is available in virtual instruments. When the gain is set to auto range, SoundCheck will automatically identify the correct level of gain to optimize the measurement signal to noise ratio.

For any hardware device, the user can specify the latencies for various sampling rates, either by entering them manually or importing from a file, and SoundCheck will automatically use the correct latency for any sampling rate specified in the stimulus editor. Digital I/O control is now a separate message step, which means that all controls for I/O settings are completely separate from other AmpConnect settings, minimizing the possibility of other parameters being changed on accident. The Portland Tool & Die MEMS microphone interfaces can now be fully controlled from within SoundCheck, offering faster setup and greater measurement reliability. TEDS Support (with compatible Listen hardware) enables automatic identification, configuration and calibration of TEDS microphones and accelerometers, saving time on initial hardware setup and whenever hardware is changed. SoundCheck 18 now includes WASAPI driver support in Windows 10, offering full multichannel support. Finally, the new Auto Delay+ algorithm offers increased accuracy for open loop measurements, especially in cases where the delay is longer than 1 second.

SoundCheck 17 New Features

Check out our short demo video for a brief introduction to all the new features in SoundCheck 17. This new Windows/Mac release offers many features to simplify multi-channel and voice controlled testing, such as a new level and cross-correlation trigger, average curve/waveform post-processing functionality, the ability to easily read and work with multichannel wave files, multiple DC Connect control, and enhanced database options. On the usability side, SoundCheck 17 offers increased flexibility in color palettes, save to MATLAB option, and the ability to recall CSV formatted text files.

Today’s modern audio devices have two important testing requirements: the ability to test a voice activated device with no analog input, and the ability to control and test multiple channels simultaneously, for example, microphone or speaker arrays. SoundCheck 17 contains a host of new features to facilitate this. For voice-activated measurements on devices with no analog input, such as smart speakers, wearables, hearables and smart home devices, the new level & cross-correlation ‘smart trigger’ offers improved performance. By using a chirp-based conditioning tone and searching for the exact log sweep frequency, it is more robust and less susceptible to false triggers than simpler level and frequency triggers.

To save time when testing smart devices where it is necessary to test microphone or speaker arrays, SoundCheck 17 can now directly read multichannel WAV files from the memory list, signal generator and stimulus steps. Also for testing multi-channel arrays, multiple DC Connects can now be controlled, independently configured, and used for data acquisition within SoundCheck. The new Average Curve/WFM post processing function which allows the average curve (or waveform) of a selected group of data in the memory list to be obtained, is particularly useful for power averaging selected curves, averaging curves from different spatial positions (e.g. microphone arrays), and complex averaging of multiple measurements with background noise. Finally, the database module has been enhanced and is now it 4x faster and 3x more space-efficient than previous versions. This is particularly important for testing modern audio products with multiple transducers (microphone arrays, multiple speakers, etc.), as these often generate large volumes of data.

Usability enhancements include improved color pallets which offer ultimate flexibility in defining colors for backgrounds, grids, cursors and graph lines. New default color palettes are included, and user-defined palettes can be saved as pre-set files which will be applied to any new display created. Multiple palettes can be saved, for example allowing different color sets for different applications. In addition, SoundCheck can now save any data (including memory list curves and Soundmap (time frequency analysis) data ) to MATLAB for additional processing. Data is saved as a standard MAT file and can be manually or automatically saved in this format.
Additional new features include support for the new APTX HD codec for high resolution Bluetooth testing, a 64 bit Demo / Data Viewer which enables measured data to be recalled and viewed without the need to own a separate license, and the ability to recall CSV files as well as TXT files.
