If you are using WinMLS for measuring electronic equipment only, such as amplifiers, cables for connecting to the sound card is in principle all the extra equipment needed.
In order to use WinMLS for other types of measurements than electrical measurements, transducers are needed. A transducer is device for transforming a quantity to another quantity. Two well-known transducers are the microphone and loudspeaker. A microphone transforms sound pressure to voltage and a loudspeaker transforms voltage to sound pressure.
In addition to microphone and loudspeaker, which will be discussed in more detail below, WinMLS supports transducers for measuring the quantities displacement, velocity, acceleration and force.
