Embodiment Construction

[0031] Referring to the accompanying drawings, a sound effect correction device according to an embodiment of the present invention will be described below.

[0032] As shown in FIG. 1 , the sound effect correction device 1 according to the embodiment of the present invention corrects the sound effects of a plurality of speakers 12 to 16 based on the measurement data calculated from the first and second collected signals and performs virtual sound image localization processing, by The first and second collecting portions 7a and 7b, which are separated from each other by a predetermined distance, that is, close to any one of the listening positions, collect the output in response to supplying measurement signals for measurement to a plurality of speakers 12 to 16 placed at arbitrary positions of the sound effect listening environment 11. The first and second collected signals are obtained by sound.

[0033] A plurality of speakers 12 to 16 are arbitrarily placed at predetermine...

Description

[0001] Cross-References to Related Applications [0002] The present invention contains subject matter related to Japanese Patent Application JP2005-334711 filed in the Japan Patent Office on Nov. 18, 2005, the entire content of which is hereby incorporated by reference. technical field [0003] The present invention relates to an acoustic correction device for correcting the acoustics of an audio system including a plurality of speakers to desired characteristics. Background technique [0004] In order to obtain high-quality sound effects in sound effects in a surround sound device including a plurality of speakers (for example, it can increase the sense of reality similar to the sound in a concert hall or a theater), an appropriate number of Place multiple speakers in one location. [0005] However, an indoor environment having such a surround sound device usually has various factors, and the arrangement of speakers is limited. [0006] An acoustic correction device for ...
