What is Digital audio?
[[File:Digital.signal.discret.svg|thumb|An example of how an analog signal could be digitized. This signal was digitized without [[dither]].]] '''Digital audio''' is sound which has been turned into a [[computer file]]. Digital audio files can be played on [[MP3 player]]s, [[computers]], [[smartphone]]s, and more. Digital audio may be uncompressed, such as [[Compact disc|CDs]] or [[WAV]] files, losslessly compressed, such as [[FLAC]] files, or lossily compressed, such as [[MP3]] files. Audio is converted to digital format using a device called an '''analog to digital converter''' (ADC). The ADC takes samples of the [[amplitude]] of the signal at a specific sample rate (for example, 44100 times per second). These samples are [[binary]] numbers. When converting back to analog, a device called a '''digital to analog converter''' (DAC) recreates the original analog signal that matches the given samples. {{stub}} [[Category:Sound]] [[Category:Electronics]]
