20110202348 | RHYTHM PROCESSING AND FREQUENCY TRACKING IN GRADIENT FREQUENCY NONLINEAR OSCILLATOR NETWORKS - 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 | 08-18-2011 |

20110191113 | METHOD AND APPARATUS FOR CANONICAL NONLINEAR ANALYSIS OF AUDIO SIGNALS - The present invention is directed to systems and methods designed to ascertain the structure of acoustic signals. The approach involves an alternative transform of an acoustic input signal, utilizing a network of nonlinear oscillators in which each oscillator is tuned to a distinct frequency. Each oscillator receives input and interacts with the other oscillators in the network, yielding nonlinear resonances that are used to identify structure in an acoustic input signal. The output of the nonlinear frequency transform can be used as input to a system that will provide further analysis of the signal. According to one embodiment, the nonlinear responses are defined as a network of n expanded canonical oscillators z | 08-04-2011 |
