Method and apparatus for acquiring the multi-channel sound with a microphone array

The invention of the sound source corresponding to the sound signal from the multi-channel sound acquisition method and relates to a device, the multi-channel sound acquisition method is a plurality of mixed sound signals input via a microphone array according to the present invention using the microphone array, by estimating the position, to compensate for the sound source signal on the basis of the difference between the position of any of the virtual microphone array assumed to be based on the position and the multi-channel sound of the estimated sound source generating a plural-channel sound source signal, a microphone in portable sound acquisition device, It may be the three-dimensional obtaining channel sound from a plurality of distant sound source signal input through the array.
