Audio CODECs for Broadcast Platforms

A codec is a device that can encode and/or decode a digital data signal. A codec encodes data for transmission and/or decodes it for playback. Essentially, a codec has one or more Digital-to-Analog data converters (DAC) and Analog-to-Digital converters (ADC) in a single package. A codec is essential for the use of Digital Signal Processors (DSPs) in audio applications, since it can convert real-world analog signals (like sound) to digital signals for the DSP, and back again from digital to analog for the human ear.
