A music extracting apparatus has a receiving unit which receives a broadcast signal having a plurality of channels of audio signals, a detecting unit which detects a variation of voice power from the audio signal, a computing unit which computes a difference of amplitude or power between the audio signals of each channel, and a specifying unit which specifies the starting or the ending position of a music section based on the variation detected by the detecting unit and the difference computed by the computing unit.
