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.
2. The method of claim 1 , further comprising obtaining the composite audible signal data.
