  • Patent number: 7203325
    Abstract: An audio processing device for processing an audio input signal comprises one or more noise reducing means, noise level measuring means and control means connected to the noise level measuring means for controlling the noise reducing means. The audio processing device further comprises an auto signal leveling circuit to which the audio input signal is supplied, while the output signal of the auto signal leveling circuit is supplied to the noise reducing means. The auto signal leveling circuit is controlled by said control means, such that, when the noise measuring means do not detect an audio signal above a certain audio level, the auto signal leveling circuit and at least one of the noise reducing means are switched on, and, when the noise measuring means detect an audio signal above said certain audio level, the auto signal leveling circuit and the noise reducing means are switched off.
