Just because you can use any hardware with SoundCheck doesn’t mean that you should! Check our our Hardware Compatibility Table to see which audio interfaces we recommend.

 

Video Script: Calibrate and Use Third Party Hardware with SoundCheck

We offer many hardware options for use with SoundCheck including audio interfaces, reference microphones, microphone power supplies, and amplifiers. Our own Listen hardware comes pre-calibrated, and the values are stored and directly read from the device. When you purchase Listen-approved third party interfaces from us, such as RME and Lynx, we pre-calibrate them and provide a hardware QC sheet containing the Vp and latency values and complete setup instructions.

While these offer the fastest path to a calibrated test setup, we also understand you may prefer to use other third-party hardware with SoundCheck, especially if you already own a suitable audio interface. So, if you are wondering if you can calibrate and use your existing audio interface with SoundCheck, the good news is that you probably can.

Calibration is recommended before you make any measurement. This involves measuring the peak voltage (Vp) that can be input or output through the audio interface before it saturates so that measurements can be scaled to full digital scale (FSD). Latency is also measured during the calibration process. Even if you’re using hardware that is not listed in our Hardware Compatibility guide, SoundCheck supports, and calibrates, most third party interfaces using WDM, WASAPI, ASIO, Core Audio and NI DAQmx drivers.

Third party audio interface calibration is a one time process which shouldn’t take more than 5 minutes and helps ensure your measurements are accurate. We provide a calibration sequence that can be run from inside the Hardware editor at the click of a button, along with documentation to outline the procedure. The only additional equipment you need is a BNC-T connector and a multimeter.

While we love the tight integration and synergy that comes with using Listen hardware with SoundCheck, we understand that flexibility is also important, given the wide variety of applications and testing needs that we support. With the ability to calibrate and use many third party audio interfaces, including high-channel count audio interfaces, and other hardware, and use multiple interfaces simultaneously, often in different modes, SoundCheck offers true measurement flexibility – with accuracy.

 

 

 

 

 

 

100 Things #2: SoundCheck Works With Any Audio Interface

Since its inception in 1995, SoundCheck was designed to use any audio interface from a professional sound card to a high precision National Instruments data acquisition card. In this short video, we explain how this flexibility permits high channel count, portability, high accuracy or low cost. This is particularly useful where you have differing needs within your organization, yet would like to all use the same measurement system. It also makes it easy to transition measurement configurations from one audio interface to another, as often happens when moving an R&D test into production.

Since we first launched SoundCheck in 1995, it has been designed to use any audio interface from a professional sound card to a high precision National Instruments data acquisition card.

This philosophy offers immense configuration flexibility, whether your needs are high channel count, portability, high accuracy or low cost. The SoundCheck software itself allows additional channels to be purchased, so it’s easy to match (and even change) your number of software channels with your interface needs.

This is particularly useful where you have differing needs within your organization, yet would like to all use the same measurement system. It also makes it easy to transition measurement configurations from one audio interface to another, as often happens when moving an R&D test into production.

While you can use any audio interface, we provide a list of tried, tested, and supported products with up to 64 channels. These all meet strict performance and latency criteria, and, when purchased through Listen, are supplied fully calibrated and ready to connect to your system.

Although this flexibility has always been integral to our product philosophy, since 2009, we’ve also offered our own audio interfaces. We’ve designed these specifically for measurement applications, adding functionality such as microphone power, amplifiers, impedance measurement, digital I/O, and signal routing, as well as high resolution options,  in a single unit with just a USB connection to the computer.

We’ve also eliminated most on-unit controls for simple error-free operation. The tight integration that our own products offer with SoundCheck enables automatic configuration for rapid set-up, and additional features such as automatic gain control, TEDS transducer calibration compatibility and more.

And naturally, our audio interfaces, as well as any recommended 3rd party products have always offered silent operation so as not to interfere with acoustic measurements.

We’re always happy to advise on the best audio interface to use with SoundCheck for your application, whether that’s one of our own products or something else.

 

New Production Line Bluetooth Interface

BQC-4148_smallThe new BQC-4148 Bluetooth interface is designed for high volume production line testing of Bluetooth sink devices such as headsets, speakers and car kits. It offers control over the CODEC choice, sample rate, and transmitter power, enabling devices to be specifically tested under the conditions that they need to operate

The unit is rugged and compact, measuring just 30 x 64 x 136mm. With only one connector – a USB for connection to the computer for power and control – it is simple to use and offers minimal potential for incorrect operation. It can be controlled via the USB virtual com port using a command line utility, or from within SoundCheck using the control utility via a system step for simple integration with your test sequences. Although it is less full-featured than its R&D counterpart, the BTC-4148, it is approximately half the cost.
