SoundCheck is built on flexibility, and it’s hardware compatibility is no exception. SoundCheck supports multiple audio interfaces and devices, all simultaneously. Freely combine and measure with analog and digital interfaces together. Use a Listen interface like AmpConnect 621, and pair it with an A2B, I2S, or Bluetooth interface for highly customizable tests.

Video Script: Soundcheck Supports Multiple Interfaces for Ultimate Flexibility
Since 1995, SoundCheck has supported the use of external sound cards and audio interfaces. But did you know that SoundCheck can support multiple audio interfaces and other audio devices simultaneously giving you ultimate flexibility for a wide range of audio test applications?
Here are some examples of test applications that take advantage of this flexibility:
Add additional audio interfaces to expand your channel input and output count, for up to 64 channels of input and output
For example, add Bluetooth, Digital MEMS, I2S, A2B interfaces and even Dante to test these devices
Directly connect a USB audio device like a USB headset, microphone or speaker to test these devices
On Windows OS, SoundCheck supports a wide range of audio drivers including WDM/MME, ASIO, WASAPI, NiDAQ (if using National Instruments hardware) and even Dante. On MacOS, SoundCheck supports CoreAudio. As long as your audio device has an input or output path through a compatible audio driver in SoundCheck, it can be used as an audio source or destination for testing in SoundCheck. Furthermore, SoundCheck can easily support mixed analog and digital signals simultaneously as well as hardware with different sampling rates.
Let’s look at a hardware setup window in SoundCheck fully exploiting this capability. In my hardware setup you can see a Listen multi channel AmpConnect 621, a BQC-4149 Bluetooth interface, an A2B interface and a USB headset all peacefully coexisting. Note: these devices use different audio drivers, mixed analog and digital signals and even different sampling rates.
With SoundCheck’s auto-delay algorithm, we can even account for latency differences outputting from one hardware device and inputting from another. For example, delays from transmitting a test stimulus to a Bluetooth device like a speaker or headphone.
SoundCheck also has resample and frequency shift post-processing steps to correct for sample rate mismatch and/or hardware clock phase differences as a result of inputting and outputting from different hardware interfaces. This means we can resample and phase align the test stimulus and response prior to analysis to assure accurate measurements.
If you’d like to verify if your device can be used with SoundCheck, please give us a shout and we’ll check it out!
