Abstract
Method for reproducing an audio signal comprising the following steps: a) acquiring an input audio signal, which acquisition occurs through one or more sensors arranged at an acquisition point of the space envisaged at the body of a user, b) processing said input audio signal, c) generating an output audio signal. Step b) includes creating an acoustic model of the anatomical district at the acquisition point, aimed at eliminating distortions caused by the user's body from said input audio signal, comprising step b) a first and a second processing of the input audio signal, the first processing comprising a filtering in space or beamforming aimed at attenuating the sounds not coming from the direction towards which the user is turned, the second processing comprising a filtering in space aimed at preserving the Head Related Transfer Function (HRTF) based on said acquisition point.
