Codec is a synthetic definition of the word “Havempresses” (encryption software) and then “decompresses” (decrypts) the file so that it can be played on the computer. Some codecs contain only the encoder, some contain only the decoder, and possibly both.
Codecs are released separately for audio and video files. A file type cannot be played if your computer lacks a codec that supports it.
