Verfahren zur automatischen Lautstärkesteuerung in einer Audiosignal-Wiedergabevorrichtung und Anordnung dazu

摘要

The present invention relates to a device and a method for automatic volume control in an audio-signal reproduction facility, whereby an audio-signal processing circuit (1), which is anyway provided for modulating the audio signal on its path, is used when the output amplifier (4) is oversaturated as indicated by an oversaturation signal (ÜS) occurring in said output amplifier, to reduce the volume at which audio signals are reproduced. Volume reduction and volume increase are achieved with various time constants, and interfering periodic oscillations are neutralized by inserting a counter which must be decremented before increasing the volume.
