  • Publication number: 20180132049
    Abstract: A nonlinear control system includes a controller, a model updater, and a model. The controller is configured to accept one or more input signals, and one or more updates generated by the model updater to produce one or more control signals. The system is configured to drive one or more transducers with the control signals to produce a rendered audio stream therefrom. The model updater is configured to analysis one or more portions of the audio stream and to update one or more aspects of the controller so as to alter performance of the transducer.
    Type: Application
