<p><P>PROBLEM TO BE SOLVED: To excellently and repetitively perform reproduction in a shorter section. <P>SOLUTION: A sound reproduction device includes: an input operation part 5 for receiving an input operation to select an arbitrary time point (center time CT) during the reproduction of sound data; a repeat buffer 41 for storing sound data of a search range SRR including the center time CT selected with the input operation; a zero-cross point detection part 45 for detecting zero-cross points ZCP1, ZCP2 where amplitude of a signal SG indicated by the sound data becomes zero and also rises from the search range SRR through use of the sound data of the search range SRR; and a repeat processing part 49 for repetitively reproducing the sound data between the two zero-cross points ZCP1, ZCP2. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
