Claim One:
1. A method for mimicking the auditory system's response to rhythm of an input signal having a time varying structure comprising the steps of: receiving a time varying input signal x(t) to a network of m nonlinear oscillators, each oscillator having a different natural frequency of oscillation and obeying a dynamical equation of the form: r. = r ( α + β 1  z  2 + ε β 2  z  4 1 - ε  z  2 ) + c x ( t ) cos φ - r ε ε r 2 - 2 ε r cos φ + 1 φ. = ω + δ 1 r 2 + ε δ 2 r 4 1 - ε r 2 - c x ( t ) sin ( φ ) ε r 2 - 2 ε r cos ( φ ) + 1 ω. = - k x ( t ) sin φ ε r 2 - 2 ε r cos φ + 1 wherein ω represents the response frequency, r is the amplitude of the oscillator and φ is the phase of the oscillator; and generating at least one frequency output from said network useful for describing said varying structure.
