Abstract:
(EN) The present invention provides a filter determination system, a filter determination device, a filter determination method, and a program, with which a filter can be appropriately determined. A processing device (200) according to this embodiment is provided with: a frequency characteristic acquisition unit (211) that acquires a frequency characteristic of a filter for an audio signal; a smoothing processing unit (212) that finds a smoothed characteristic by smoothing the frequency characteristic; a candidate point determination unit (213) that determines division candidate points on the basis of a bottom position of the smoothed characteristic; and a division point determination unit (214) that determines one or more band division points from among the division candidate points.
(FR) L'invention concerne un système de détermination de filtre, un dispositif de détermination de filtre, un procédé de détermination de filtre et un programme, au moyen desquels un filtre peut être déterminé de manière appropriée. Un dispositif de traitement (200), selon ce mode de réalisation, comporte : une unité d'acquisition de caractéristiques de fréquence (211) qui acquiert une caractéristique de fréquence d'un filtre pour un signal audio; une unité de traitement de lissage (212) qui trouve une caractéristique lissée par lissage de la caractéristique de fréquence; une unité de détermination de points candidats (213) qui détermine des points candidats de division sur la base d'une position inférieure de la caractéristique lissée; et une unité de détermination de points de division (214) qui détermine un ou plusieurs points de division de bande parmi les points candidats de division.
(JA) 適切にフィルタを決定することができるフィルタ決定システム、フィルタ決定装置、フィルタ決定方法、及びプログラムを提供する。 本実施の形態にかかる処理装置(200)は、オーディオ信号用のフィルタの周波数特性を取得する周波数特性取得部(211)と、周波数特性を平滑化して、平滑化特性を求める平滑化処理部(212)と、平滑化特性のボトム位置に基づいて、分割候補点を決定する候補点決定部(213)と、分割候補点から1つ以上の帯域分割点を決定する分割点決定部(214)と、を備えたものである。
