Abstract

Methods and systems are provided for noise suppression in data, particularly data comprising video and/or audio data. An input adjustment, based on a corresponding input adjustment value, may be applied to received input data that comprises video and/or audio data; and an output adjustment, based on a corresponding output adjustment value, may be applied to output data corresponding to previously processed received input data. The input adjustment value may be re-calculated based on an outcome of applying the input adjustment to the received data, and when a change occurs in the input adjustment value the change in the input adjustment value may be applied to subsequent received input data, and at the same time, and based on the change in the input adjustment value, a corresponding change may be applied at least some of data corresponding to previously processed received input data.
