Sound card

A standard Windows compatible sound card is needed to perform measurements. There is a wide range of sound card available (we would have preferred to call it “sound device” instead of “sound card”, since USB devices can also be used, but the term “sound card” is so widely used that we continue to use it.).

For performing measurements that require an output signal, such as loudspeaker measurements, the sound card must be full duplex. A full duplex sound card is able to record and play simultaneously. Most sound cards are full duplex, but a few sound cards are still not capable of performing MLS measurements with WinMLS. See the help section named “Tested Sound Cards” (or the pdf-file with the same name) for sound card recommendations, more information, and a list of tested sound cards.
