codec(1) (enCOder/DECoder) A hardware circuit that performs analog-to-digital conversion (ADC) and digital-to-analog (DAC) conversion. When analog signals are entered into a computer, cellphone or other device via a microphone or video source such as VHS tape or analog TV, an ADC creates the raw digital audio or video samples. Quite often, the results are then further compressed to save bandwidth (see definition #2). codec [′kō‚dek] (electronics) A device that converts analog signals to digital form for transmission and converts signals traveling in the opposite direction from digital to analog form. Derived from coder-decoder.
