Digital audio is technology that can be
used to record, store, generate, manipulate, and reproduce sound using audio
signals that have been encoded in digital form. Following significant advances
in digital audio technology during the 1970s, it gradually replaced analog
audio technology in many areas of sound production, sound recording (tape
systems were replaced with digital recording systems), sound engineering and
telecommunications in the 1990s and 2000s.


 


A microphone converts sound (a singer's
voice or the sound of an instrument playing) 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. This digital
signal can then be recorded, edited and modified using digital audio tools. When
the sound engineer wishes to listen to the recording on headphones or
loudspeakers (or when a consumer wishes to listen to a digital sound file of a
song), 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. Unlike analog audio, in which making copies of a
recording leads to degradation of the signal quality, when using digital audio,
an infinite number of copies can be made without any degradation of signal
quality.
