SOUND PROCESSING APPARATUS AND METHOD FOR SOUND ENHANCEMENT

The invention relates to a sound processing apparatus (100) configured to process a current noisy sound signal comprising a target signal and a current noise signal into an enhanced sound signal. The apparatus (100) comprises processing circuitry configured to provide an adjustable neural network (103, 107), wherein the adjustable neural network (103, 107) is configured: in a training phase, to be trained using as a first input a training noise signal, as a second input a training sound signal comprising a training target signal and the training noise signal and as a third input the training target signal; and, in an application phase, to adjust on the basis of the current noise signal and to generate an estimated noise signal on the basis of the sound signal comprising the target signal and the current noise signal. In the application phase, the processing circuitry is further configured to process the sound signal into the enhanced sound signal on the basis of the estimated noise signal. Moreover, the invention relates to a corresponding sound processing method.
