Abstract
A music playing apparatus includes: a sound and silence determining unit determining whether or not each frame included in first and second output PCM data is a sound frame including a sample having an output level not lower than a predetermined threshold; a connection point extracting unit extracting a candidate connection point being a sample having a largest variation in a lean of a PCM waveform, from each of the determined sound frames; an end detecting unit detecting candidate connection points included in a last sound frame of the first output PCM data and an initial sound frame of the second output PCM data, respectively, as a first connection point and a second connection point; and a tune continuously-output unit connecting the first output PCM data to the second output PCM data at the first and the second connection points, and playing the connected data.
