PROBLEM TO BE SOLVED: To provide a signal processor for a microphone array and a microphone array system for collecting a voice whose frequency band is low by using a compact microphone array. SOLUTION: A signal processor (4) having delay units (411-1 to 411-M) for respectively adding delay to a plurality of voice signals to be output from a plurality of microphones configuring a microphone array and an adder (412) for totaling the plurality of voice signals respectively added with delay includes a harmonic structure detecting part (421) for detecting the harmonic structure of a voice included in the voice signal and a filter part (422) through which predetermined frequency components are made to selectively pass on the basis of the detected harmonic structure.
