In which audio systems, the sound is first converted into analog electrical signals using a microphone as a transducer? Correct Answer Digital

In digital audio systems, the sound is first converted into analog electrical signals using the microphone as a transducer. Then those analog signals are converted into digital signal using analog to digital converter. Then that data can be used to record, store, generate, manipulate and reproduce sound.
