发明名称 Noise reduction in multi-microphone systems
摘要 <p>An apparatus comprising: an input configured to receive at least three microphone audio signals, the at least three microphone audio signals comprising at least two near microphone audio signals generated by at least two near microphones located near to an desired audio source and at least one far microphone audio signal generated by a far microphone located further from the desired audio source than the at least two near microphones; a first interference canceller module configured to generate a first processed audio signal based on a first selection from the at least three microphone audio signals, the first selection being from the near microphone audio signals; at least one further interference canceller module configured to generate at least one further processed audio signal based on at least one further selection from the at least three microphone audio signals, the at least one further selection from the at least three microphone audio signals, the second selection being from all of the microphone signals; a comparator configured to determine from the first processed audio signal and the at least one further processed audio signal the audio signal with greater noise suppression.</p>
