発明の名称 (英語) ACOUSTIC PROGRAM, ACOUSTIC DEVICE, AND ACOUSTIC SYSTEM NEW
発明の概要(英語) The present invention easily reproduces a sound field model from 2D image data. Further, the present invention can easily obtain a acoustic filter of unknown image data, the parameters of which are not clear. This acoustic device 100 constituting a control unit of an acoustic system is configured by connecting an imaging device 2, a sound collecting device 3, and a storage device 4 to a calculation unit 101 mainly configured by a computer. The calculation unit 101 functions as an encoder which associates, with an unknown image, a space acoustic filter coefficient for three-dimensionally reproducing a sound field. Further, a decoder formed by connecting a reproduction device to the calculation unit 101 can be configured as a separate body from the acoustic device 100. Therefore, a sound, to which a residual sound obtained from space acoustic filter characteristics corresponding to the unknown image is added, and which corresponds to the 2D image, can be output from the reproduction device.
従来技術、競合技術の概要(英語) BACKGROUND ART
Conventional, in the field of acoustic technology, such as in situ the actual natural heard differently (hereinafter, also referred to as a sense of realism) to, by performing filter processing unique to the recording of a reverberant sound field (hereinafter, also referred to as reverberation) such as three-dimensionally reproduce the acoustic characteristics of the audio system has been studied (for example, see Patent Document 1-4).
