Revert back. I have taken a university course in audio encoding, programmed my own encoder. The fact that audio codecs use a psychoacustic model in this way is beginner knowledge. Please don't revert edits on subjects you don't understand. |

Line 9:
==Lossless, lossy, and uncompressed audio coding formats==
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, as well as sounds which are believed to be inaudible to humans according to a psychoacoustic model, 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. Lossless audio coding formats such as [[FLAC]] and [[Apple Lossless]] are sometimes available, though at the cost of larger files.
