SOUND COLLECTING DEVICE, SOUND COLLECTING METHOD, SOUND COLLECTING PROGRAM, AND INTEGRATED CIRCUIT

摘要

Provided is a sound collecting device which can generate a multi-channel signal for realizing sound image localization without processing current position information when using a freely-movable microphone. The sound collecting device includes: a plurality of reference microphones which are fixedly arranged to correspond to respective channels so as to collect an incoming speaker's voice and output a reference signal expressing a signal of a corresponding channel; at least one actual recording microphone which is movably arranged to collect an incoming speaker's voice and output the voice as an actual recorded signal; and signal generation means which executes a predetermined calculation process on the actual recorded signal from the actual recording microphone according to the reference signal from each of the reference microphones so as to generate signals of the respective channels.
