Digital audio
Digital audio is technology that can be used to record, store, generate, manipulate, and reproduce sound using audio signals encoded in digital form.
Following significant advances in digital audio technology during the 1970s, it rapidly replaced analog audio technology in most areas of sound production, sound engineering and telecommunications.
A microphone converts sound to an analog electrical signal, then an analog-to-digital converter (ADC) -- typically using pulse-code modulation -- converts the analog signal into a digital signal.
A digital-to-analog converter performs the reverse process, converting a digital signal back into an analog signal, which analog circuits amplify and send to a loudspeaker.
Digital audio systems may include compression, storage, processing and transmission components.
Conversion to a digital format allows convenient manipulation, storage, transmission and retrieval of an audio signal.
