摘要： A system and/or media network for rendering a media stream from one or more media rendering devices is disclosed. The media network may include one or more configurable peers, each configurable peer configurable as a rendering device, an observer, a processing device, a combination thereof, or the like. The system may be particularly suitable for use in remote locations, to generate a controlled and/or shared meeting topology within an uncontrolled media environment, and/or to generate an intense sound field amongst a group of participants from a collection of associated peers.

摘要： A nonlinear control system and a loudspeaker protection system. In particular, a nonlinear control system including a controller, an audio system, and a model is disclosed. The controller is configured to accept one or more input signals, and one or more estimated states produced by the model to produce one or more control signals. The audio system includes one or more transducers configured to accept the control signals to produce a rendered audio stream therefrom. An active loudspeaker with an integrated amplifier is disclosed. A loudspeaker protection system and a quality control system are disclosed. More particularly, a system for clamping the input to a loudspeaker dependent upon a bank of representative models is disclosed.
