摘要： Storage section (20) has stored therein music piece data sets of a plurality of music pieces, each of the music piece data sets including respective tone data of a plurality of fragments of the music piece and respective character values indicative of musical characters of the fragments. Each of the fragments of a selected main music piece is selected as a main fragment, and each one, other than the selected main fragment, of a plurality of fragments of two or more music pieces is selected as a sub fragment. A similarity index value indicative of a degree of similarity between the character value of the main fragment and the character value of the specified sub fragment is calculated. For each of the main fragments, a sub fragment presenting a similarity index value that satisfies a predetermined selection condition is selected. The tone data of each of the main fragments of the main music piece is processed on the basis of the tone data of the sub fragment selected for the main fragment.

摘要： The invention provides an audio encoder for encoding an audio signal (AS) so as to produce therefrom an encoded signal (ES), the audio encoder (1) comprising: a framing device (2) configured to extract frames (F) from the audio signal (AS); a quantizer (3) configured to map spectral lines (SL
1-32 ) of a spectrum signal (SPS) derived from the frame (F) of the audio signal (AS) to quantization indices (I
0 , I
1 ), wherein the quantizer (3) has a dead-zone (DZ), in which the input spectral lines (SL) are mapped to quantization index zero (I
0 ); and a control device (4) configured to modify the dead-zone (DZ); wherein the control device (4) comprises a tonality calculating device (5) configured to calculate at least one tonality indicating value (TI
5.32 ) for at least one spectrum line (SL
1-32 ) or for at least one group of spectral lines (SL
1-32 ), wherein the control device (4) is configured to modify the dead-zone (DZ) for the at least one spectrum line (SL
1-32 ) or the at least one group of spectrum lines (SL
1-32 ) depending on the respective tonality indicating value (TI
5-32 ).

摘要： Storage section (20) has stored therein music piece data sets of a plurality of music pieces, each of the music piece data sets including respective tone data of a plurality of fragments of the music piece and respective character values indicative of musical characters of the fragments. Each of the fragments of a selected main music piece is selected as a main fragment, and each one, other than the selected main fragment, of a plurality of fragments of two or more music pieces is selected as a sub fragment. A similarity index value indicative of a degree of similarity between the character value of the main fragment and the character value of the specified sub fragment is calculated. For each of the main fragments, a sub fragment presenting a similarity index value that satisfies a predetermined selection condition is selected. The tone data of each of the main fragments of the main music piece is processed on the basis of the tone data of the sub fragment selected for the main fragment.
