1. A method for neural processing, comprising:

  • receiving a signal;

    filtering the signal into a plurality of channels using a plurality of filters having different frequency passbands;

    sending the filtered signal in each of the channels to a first type of spiking neuron model;

    sending the filtered signal in each of the channels to a second type of spiking neuron model; and

    identifying one or more spectral peaks in the signal based on a first output of the first type of spiking neuron model and a second output of the second type of spiking neuron model for each of the channels, wherein each of the spectral peaks comprises a relative concentration of power in a frequency spectrum of the signal.
