Abstract: An audio codec system which uses a memory to buffer frames of audio while signal power levels of the frames of audio buffered in the memory are detected to generate a signal power look-forward value and zero-crossing points of the frames of audio buffered in the memory are detected to obtain available calibration points for gain control due to a change of the signal power look-forward value. The gain control is divided to be performed at the available calibration points.
