A digital audio or video file consists of a container holding source data which has been processed through a codec. A codec (coder-decoder, compressor-decompressor, compress-decompress) transforms the analog signal (from a microphone, video camera, etc.) into the ones and zeros of a digital file. A codec also can be used to encode material already existing in digital format into another digital format.
