  • Automatic volume leveler
    Patent number: 5363147
    Abstract: A circuit for controlling a reproduced volume level of an audio signal to a desired level includes a peak detector for detecting a peak amplitude level in the audio signal, a user operable control for generating a signal indicative of a desired amplitude level, a comparator for comparing the detected peak amplitude level in the audio signal with the desired amplitude level and for generating a comparison signal as a result of the comparison, and a voltage controlled amplifier coupled to the comparator for adjusting the peak amplitude level in the audio signal in dependence on the comparison signal. The output from the voltage controlled amplifier then has the desired level.
