The present invention provides a sound collecting device capable of, even when using a freely-movable microphone, generating multichannel signals realizing sound image localization without processing using information about the current position of the microphone. The sound collecting device includes: reference microphones fixedly placed so as to correspond to the respective channels, the reference microphones collecting an arriving sound from the speaker, and outputting reference signals representing signals of the respective channels; at least one actual recording microphone placed so as to be movable, the at least one actual recording microphone collecting the arriving sound from the speaker, and outputting the collected sound as an actual recording signal; and signal generation means for generating signals of the respective channels by performing, based on the reference signals outputted by the reference microphones, predetermined calculation processing for the actual recording signal outputted by the at least one actual recording microphone.
