Abstract
A system and method of operating a codec in an operational mode are disclosed. The codec is operated in a digital centric mode. The digital centric mode involves the following: An analog mixer of the codec first mixes analog signals, if any, to produce a mixed analog signal. An analog-to-digital converter converts the mixed analog signal into a converted digital signal. A digital mixer mixes the converted digital signal with digital signals that are otherwise generally unavailable as analog signals to the codec without additional conversions to produce a mixed digital signal. A digital-to-analog converter converts the mixed digital signal into a mixed analog signal. A digital processor may perform digital effects processing on the mixed digital signal to add digital effects to the mixed digital signal. The codec is still able to alternatively operate in an analog centric mode, a host processing mode, or a multi-channel mode.
