audio codec

(1) A hardware circuit that converts analog voice into PCM or ADPCM digital code and vice versa. The term may refer to only the A/D and D/A conversion, or it may include the compression technique for further reducing the signal (definition #2 below). See sampling and codec.

(2) Hardware and/or software that compresses and decompresses a PCM or ADPCM digital audio signal. If the codec is specialized for human voice, it is known as a "speech codec," "voice codec" or "vocoder" (see speech codec). See audio compression, perceptual audio coding, codec examples and G. standards.
