Abstract:
1. A method of operating an audio processing device for processing an electric input signal representing a first sound signal or sound component and providing a processed electric output signal, the method comprising: a) receiving the electric input signal representing the first sound signal or the sound component; b) providing an event-control parameter indicative of changes related to the electric input signal and for controlling the processing of the electric input signal; c) storing a representation of the electric input signal or a part thereof; d) providing the processed electric output signal with a configurable delay based on the stored representation of the electric input signal or a part thereof and controlled by the event-control parameter, wherein the time-delay of the first sound signal or the sound component is minimized by combination with a frequency transposition of the signal, wherein the frequency transposition is based on a model of the human auditory system, wherein the first sound signal or the sound component is transposed in frequency to utilize a faster release from masking, wherein the model of the human auditory system, including the masking threshold vs. frequency, is customized to a hearing impairment of a particular user, wherein the user's own voice is separated from other acoustic sources, and wherein the electric input signal is separable into a first electric input signal representing an acoustic source other than the user's own voice and a second electric input signal representing the user's own voice.
