Abstract
A device for digital aurally compensated loudness control of audio signals, comprising two fine-stepped resistor chains connected in a series connection which on one end is adapted to be acted upon by the audio signal to be attenuated and whose connection point has a correction impedence connected thereto, and comprising one coarse-stepped resistor chain which at one end receives the fine-attenuated audio signal taken off from one fine-stepped resistor chain and which has at least one feed-in terminal at a predetermined location along the coarse-stepped resistor chain into which is fed a fine-attenuated audio signal taken off from the other fine-stepped resistor chain. The output signal of the device is taken off from the coarse-stepped resistor chain.
