Application ID: 14169613

Base Claim:
1. A method of directionally filtering portions of an audible signal, the method comprising: determining one or more directional indicator values from composite audible signal data, the composite audible signal data including a respective audible signal data component from each of a plurality of audio sensors; determining a gain function from the one or more directional indicator values, the gain function targeting one or more portions of the composite audible signal data, wherein generating the gain function from the one or more directional indicator values includes determining, for each directional indicator value, a respective component-gain function based on the directional indicator value and a corresponding target value associated with the directional indicator value, and the respective component-gain function includes a distance function of the directional indicator value and the corresponding target value; and filtering the composite audible signal data using the gain function in order to produce directionally filtered audible signal data, the directionally filtered audible signal data including one or more portions of the composite audible signal data that have been changed by filtering with the gain function.

Claim 11:
11. The method of claim 1 , wherein determining the one or more directional indicator values from the composite audible signal data includes determining one or more first directional indicator values from at least two of the respective audible signal data components, the one or more first directional indicator values are representative of a degree of similarity between the respective audible signal data components.
