A [[lossless compression|lossless]] audio coding format reduces the total data needed to represent a sound but can be de-coded to its original, uncompressed form. A [[lossy compression|lossy]] audio coding format additionally reduces the [[audio bit depth|bit resolution]] of the sound on top of compression, which results in far less data at the cost of irretrievably lost information.

Consumer audio is most often compressed using lossy audio codecs as the smaller size is far more convenient for distribution. LosslessThe most widely used audio coding formats such asare [[FLACMP3]] and [[AppleAdvanced LosslessAudio Coding]] (AAC), both of which are sometimeslossy available,formats thoughbased aton the[[modified costdiscrete ofcosine largertransform]] (MDCT) and [[perceptual coding]] filesalgorithms.

[[UncompressedLossless audio]] coding formats, such as [[pulse-codeFLAC]] modulationand [[Apple Lossless]] (.wav)are sometimes available, arethough alsoat sometimesthe cost of larger usedfiles.

[[Uncompressed audio]] formats, such as [[pulse-code modulation]] (PCM, or .wav), are also sometimes used. PCM was the standard format for [[Compact Disc Digital Audio]] (CDDA), before lossy compression became the standard with MP3.
