Abstract
Provided is a signal processing apparatus that includes a reference signal generating section that generates a reference signal corresponding to a target sound on the basis of a mixed sound signal which is recorded with multiple microphones arranged at different positions and is a mixture of the target sound and a non-target sound. The signal processing apparatus further includes a sound source extracting section that extracts, from the mixed sound signal of one frame or multiple frames, a signal of one frame which is similar to the reference signal and in which the target sound is more enhanced.
