Abstract
A method, device and system enhance an audio signal in a receiving device. The method comprises acoustically propagating a target signal from an acoustic source along an acoustic propagation path, providing a propagated acoustic signal at the receiving device; converting the received propagated acoustic signal to a propagated electric signal, the received propagated acoustic signal comprising the target signal, noise and possible other sounds from the environment as modified by the propagation path from the acoustic source to the receiving device; wirelessly transmitting a signal comprising the target audio signal to the receiving device; receiving the wirelessly transmitted signal in the receiving device; retrieving a streamed target audio signal from the wirelessly received signal comprising the target audio signal; and estimating the target signal from the propagated electric signal and the streamed target audio signal using an adaptive system.
