Abstract
Disclosed is an audio signal processing device comprising an input for receiving a noisy audio signal, a variable gain component and a noise suppression component. The noisy audio signal has a desired audio component and a noise component. The variable gain component and the noise suppression component are respectively configured to apply a gain and a noise suppression procedure to the audio signal, thereby generating a gain adjusted noise reduced audio signal. The aggressiveness of the noise suppression procedure is rapidly changed responsive to a change in the applied gain. That change is a change from a current value by an amount substantially matching the change in applied gain to a new value. The aggressiveness is then gradually returned to the current value.
