Audio processing device comprising artifact reduction

An audio processing device comprising

• a forward path comprising
• an input unit for delivering a time varying electric input signal representing an audio signal, the electric input signal comprising a target signal part and a noise signal part,
• a signal processing unit for applying a processing algorithm to said electric input signal and providing a processed signal, and
• an output unit for delivering an output signal based on said processed signal, and
• an analysis path comprising
• a model unit comprising a perceptive model of the human auditory system and providing an audibility measure,
• an artifact identification unit for identifying an artifact introduced into the processed signal by the processing algorithm and providing an artifact identification measure, and
• a gain control unit for controlling a gain applied to a signal of the forward path by the processing algorithm based on inputs from said model unit and said artifact identification unit.
