Abstract:
1. A method comprising: using a component analyzer to decompose input signals into input signal components representing different frequency components at each of a series of times; using a prototype generator to determine a characterization of one or more prototype signals from the input signals, the characterization of the one or more prototype signals comprising a plurality of prototype components representing different frequency components at each of the series of times; and using an estimator, executed by a sound processing device, to process a prototype signal of the one or more prototype signals to form an output signal as an estimate of the prototype signal, the estimate being based on, and varying in accordance with, the input signals used to determine a characterization of the prototype signal, the output signal corresponding to a combination of the input signals used to determine the characterization of the prototype signal; wherein forming the output signal as an estimate of the prototype signal comprises determining a minimum error estimate of the prototype signal.
