ABSTRACT:
The magnitude of analog audio input signal to an analog to digital converter in a digital audio processing system is increased or decreased in response to the magnitude of a sample of the digitized audio signal being found below or above, respectively, an acceptable range of magnitudes of the analog audio input signal. The magnitude of an audio output signal is correspondingly decreased or increased, after a delay equal to the processing delay. Additionally the increase of the magnitude of the audio input signal is delayed by a predetermined period, e.g., five to thirty seconds, during which the magnitude of the audio input signal remains below the acceptable input magnitude range.
