1. A method of signal processing, said method comprising:

  • based on a plurality of M-channel training signals, training a plurality of coefficient values of a source separation filter structure to obtain a converged source separation filter structure, where M is an integer greater than one; and

    deciding whether the converged source separation filter structure sufficiently separates each of the plurality of M-channel training signals into at least a information output signal and an interference output signal,wherein at least one of the plurality of M-channel training signals is based on signals produced by M transducers in response to at least one information source and at least one interference source while the transducers and sources are arranged in a first spatial configuration, andwherein another of the plurality of M-channel training signals is based on signals produced by M transducers in response to at least one information source and at least one interference source while the transducers and sources are arranged in a second spatial configuration different than the first spatial configuration.
