In software, a codec is a computer program that compresses/decompresses digital audio data according to a given audio file format or streaming audio format. The object of a codec algorithm is to represent the high-fidelity audio signal with minimum number of bits while retaining the quality. This can effectively reduce the storage space and the bandwidth required for transmission of the stored audio file.
