12. An acoustic signal processing method comprising:
generating a signal for canceling noise according to a sound signal inputted from a corresponding one of multiple microphones, by a digital noise cancelling filter that is provided for each of the multiple microphones;
generating a control parameter for the noise canceling filter and analyzing the sound signals inputted from the microphones, by a processor; and
processing an external input signal inputted from an outside, by a digital filter, wherein
the external input signal includes an audio object and meta information corresponding to the audio object, and
the processor further changes a reproduction position of the audio object in accordance with the meta information and noise arrival direction information which is generated according to the sound signals inputted from the microphones, and generates a control parameter for the digital filter.
