Abstract:
1. A reproduction device comprising: a decoding unit configured to sequentially decode compressed musical data to be reproduced; a threshold calculating unit configured to calculate an average amplitude level in a predetermined section of an end portion of first musical data generated by decoding first compressed musical data by the decoding unit, and calculate a threshold for detecting a silent portion in the end portion of the first musical data on the basis of the calculated average amplitude level; a reproduction ending position detector detecting a position of the first musical data as a reproduction ending position used at a time of reproduction of the first musical data, wherein the position is nearest to an end position of the first musical data at an amplitude level which is the threshold calculated by the threshold calculating unit or more; a reproduction starting position detector detecting a position of second musical data, which is generated by decoding second compressed musical data to be reproduced next to the first compressed musical data by the decoding unit, as a reproduction starting position used at a time of reproduction of the second musical data, wherein the position is near a leading position of the second musical data at an amplitude level which is the threshold or more; and a reproducing unit configured to reproduce the first musical data until the reproduction ending position and then reproduce the second musical data from the reproduction starting position.
