Abstract:
(EN) In the present invention, when generating adjustment information (TUI), a generation unit (133A) generates reference octave band information (ROCBE,k) by averaging the octave band information (OCBE,k#r) (r = 1, …) for European music. The generation unit (133A) also performs cluster analysis on octave band information (OCBj,k#q) (q = 1, …) for a plurality of music pieces created in an area (ARj) to generate group octave band information (GOCBj,k#cl)(cl = 1, …, CL). Next, a selection unit (134A) calculates the similarities between the reference octave band information (ROCBE,k) and each of the group octave band information (GOCBj,k#cl), and selects group octave band information that has the least similarity to the reference octave band information (ROCBE,k). The selection unit (134A) creates the octave band information (OCBj,k) on the basis of the selected group octave band information.
(FR) Dans la présente invention, lors de la génération d'informations de réglage (TUI), une unité de génération (133A) génère des informations de bande d'octave de référence (ROCBE,k) en faisant la moyenne des informations de bande d'octave (OCBE,k#r) (r = 1, …) pour la musique européenne. L'unité de génération (133A) réalise également une analyse de groupement sur des informations de bande d'octave (OCBj,k#q) (q = 1, …) pour une pluralité de morceaux de musique créés dans une zone (ARj) pour générer des informations de bande d'octave en groupe (GOCBj,k#cl)(cl = 1, …, CL). Ensuite, une unité de sélection (134A) calcule les similitudes entre les informations de bande d'octave de référence (ROCBE,k) et chacune des informations de bande d'octave en groupe (GOCBj,k#cl), et sélectionne des informations de bande d'octave en groupe qui sont similaires aux informations de bande d'octave de référence (ROCBE,k). L'unité de sélection (134A) crée les informations de bande d'octave (OCBj,k) sur la base des informations de bande d'octave en groupe sélectionnées.
(JA) 調整情報(TUI)の生成に際して、生成部(133A)は、ヨーロッパの楽曲のオクターブバンド情報(OCBE,k#r)(r=1,…)を平均して、参照オクターブバンド情報(ROCBE,k)を生成する。また、生成部(133A)は、地域(ARj)において作製された複数の楽曲のオクターブバンド情報(OCBj,k#q)(q=1,…)をクラスタ分析して、グループオクターブバンド情報(GOCBj,k#cl)(cl=1,…,CL)を生成する。次いで、選択部(134A)が、参照オクターブバンド情報(ROCBE,k)と、グループオクターブバンド情報(GOCBj,k#cl)のそれぞれとの類似度を算出し、参照オクターブバンド情報(ROCBE,k)との類似度が最も小さいグループオクターブバンド情報を選択する。そして、選択部(134A)は、選択されたグループオクターブバンド情報に基づいて、オクターブバンド情報(OCBj,k)を生成する。
