Abstract: A sound leveling system for maintaining an output signal below a slope of predetermined maximum output levels includes a signal adjusting circuit, an integrator, and a peak rate limiter circuit. The signal adjusting circuit receives input signals and a control signal to produce the output signal that are output by the system. The signal adjusting circuit uses the control signal from the integrator circuit with the input signal to produce a gain that adjusts the output signal in accordance with the control signal such that output signal is maintained below the slope of predetermined maximum output levels. The integrator circuit is coupled to the signal adjusting circuit to receive and sample the produced output signal. The integrator circuit then determines a maximum amplitude of the output signal and uses the maximum amplitude to produce the control signal. The control signal determines a rate of response of the system, a control threshold, and a level of output slope control applied to the output signal.
