<p>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 n nonlinear oscillators, each oscillator having a different natural frequency of oscillation and obeying a dynamical equation of the form r . = r ( alpha + beta 1 z 2 + epsilon beta 2 z 4 1 - epsilon z 2 ) + c x ( t ) cos φ- r epsilon epsilon r 2 - 2 epsilon r cos φ+ 1φ. = omega + delta 1 r 2 + epsilon delta 2 r 4 1 - epsilon r 2 - c x ( t ) sin (φ) epsilon r 2 - 2 epsilon r cos (φ) + 1 omega . = - k x ( t ) sin φepsilon r 2 - 2 epsilon r cos φ+ 1 wherein omega represents the response frequency, r is the amplitude of the oscillator and phi is the phase of the oscillator. Generating at least one frequency output from said network useful for describing said varying structure.</p> |
