Following significant advancesin digital audio technology during the 1970s, it gradually replaced analogaudio technology in many areas of sound production, sound recording (tapesystems were replaced with digital recording systems), sound engineering andtelecommunications in the 1990s and 2000s.   A microphone converts sound (a singer'svoice or the sound of an instrument playing) to an analog electrical signal,then an analog-to-digital converter (ADC)-typically using pulse-codemodulation-converts the analog signal into a digital signal. This digitalsignal can then be recorded, edited and modified using digital audio tools. Whenthe sound engineer wishes to listen to the recording on headphones orloudspeakers (or when a consumer wishes to listen to a digital sound file of asong), a digital-to-analog converter performs the reverse process, converting adigital signal back into an analog signal, which analog circuits amplify andsend to a loudspeaker.   Digital audio systems may includecompression, storage, processing.
