Multichannel audio test is simple in SoundCheck with up to 64 channels of simultaneous acquisition; in reality, your channel count is only limited by your hardware interfaces and computer processing speed. Both hardware and software channels can be added at any time after purchase, enabling your system to truly expand with your needs. In this short video, we demonstrate the flexibility of Listen’s multichannel setup, using multiple interfaces and driver types can be used in the same setup. We show simultaneous play and record on different devices, and introduce some of the features recently introduced for multichannel testing.

Video Script: Multichannel Audio Test with up to 64 Channels Simultaneously
SoundCheck handles up to 64 channels of simultaneous acquisition. We’ve offered full multichannel acquisition with a steadily increasing number of channels since 2007, reaching 64 measurement channels in 2015! The reality is, that these days, your channel count is limited by your hardware interfaces and computer processing speed rather than the number of channels that can be configured in SoundCheck.
Listen’s multichannel setup is extremely flexible. SoundCheck can play and record simultaneously on different devices. Multiple Listen audio hardware or 3rd party interfaces can be used in the same test setup. You can even use devices with different driver types concurrently e.g. WDM, WASAPI, ASIO, Core Audio & NI DAQ.
The modularity of the SoundCheck platform means channels can be added at any time, so if your testing needs change after you purchase a system, it’s simple and cost-effective to increase your channel count and add interface hardware.
The software has also gained many new multichannel testing features in recent years. Back in 2012 we introduced batch processing to handle data from multiple channels simultaneously.
In 2019, we added the capability for SoundCheck to open multichannel WAV files into the memory list, signal generator and stimulus steps, conveniently auto-naming and grouping the channels together.
This year, we introduced our Multichannel RTA, which allows real time measurement and viewing of multiple signal paths simultaneously to present a convenient view of multiple signal paths across a wide range of applications. Settings such as signal path gain, octave band resolution, weighting, averaging and time-weighting can be set independently for each channel for complete measurement flexibility. The RTA also has a calculation module which allows the user to Power Average the spectra from two or more signal paths.
We also launched our own 6-in 2-out high resolution audio test interface, AmpConnect 621 which further simplifies multichannel measurements with TEDs compatible inputs, integrated amplifier and impedance measurements, and simple plug and play operation.
One thing that’s for sure… with today’s voice-activated devices, advanced headphones and hearables, automotive audio and more, multichannel testing is here to stay, and SoundCheck has all the functionality you need to implement multichannel tests across a wide range of devices at a cost effective price.
