-Contrary to popular myths, a codec is not the same thing as a format. A compression format is //a way// audio or video data are encoded, which is described in its specification (if it is standardized,​ it can be called a standard). An audio or video codec (a codec means en**co**der/​**dec**oder) is a software or hardware //tool// that encodes or decodes audio or video data. Tools used for encoding are called encoders, tools used for decoding are called decoders. Software codecs, encoders and decoders are typically implemented as libraries. ​+Contrary to popular myths, a codec is not the same thing as a format.
