Scene and State Augmented Signal Shaping and Separation

摘要

Scene and/or state information may be used to facilitate processing an input to separate one or more signals within the input, to shape the signal within the input, and/or for other processing of the input or signal(s) within the input. A scene determination may be made based upon location data, time data, data describing the received input, or other basis. A state determination may be made based upon the scene determination, properties of a signal itself, or other information such as location, time, etc. By determining an appropriate scene and/or state, processing of an input and/or a signal within an input may proceed in a fashion determined to provide the most valuable information for output. Systems and methods in accordance with the invention may be implemented in a wide variety of baseband processing systems, such as hearing aids and energy consumption monitoring systems.

主权项

1. A method for processing a signal, the method comprising:
receiving an input, the input comprising noise and at least one signal during at least some of the time the input is received, the relative magnitude of the noise and the signal varying during the time the input is received; determining a scene corresponding to the received input, the scene dependent upon at least one condition external to the signal anticipated in the received input; identifying at least one signal in the received input; analyzing the at least one signal to determine a state dependent upon at least one characteristic of the signal; processing the received input and the at least one signal within the received input based upon both the determined scene corresponding to the received input and the determined state of the signal; and outputting a processed signal derived from the at least one received signal.
