  • Auditory signal processor using spiking neural network and stimulus reconstruction with top-down attention control
    Patent number: 10536775
    Abstract: An auditory signal processor includes a filter bank generating frequency components of a source audio signal; a spatial localization network operative in response to the frequency components to generate spike trains for respective spatially separated components of the source audio signal; a cortical network operative in response to the spike trains to generate a resultant spike train for selected spatially separated components of the source audio signal; and a stimulus reconstruction circuit that processes the resultant spike train to generate a reconstructed audio output signal for a target component of the source audio signal. The cortical network incorporates top-down attentional inhibitory modulation of respective spatial channels to produce the resultant spike train for the selected spatially separate components of the source audio signal, and the stimulus reconstruction circuit employs convolution of a reconstruction kernel with the resultant spike train to generate the reconstructed audio output.
