Abstract
(EN)
An audio signal mixer can be applied to a DJ device and the like, for example. The audio signal mixer acquires a plurality of audio signals and acquires mixing rate information being information on a mixing rate of a plurality of the audio signals. The audio signal mixer decides an adjusting amount of balance between levels at every band when a plurality of the audio signals are mixed based on the mixing rate. A plurality of the audio signals are mixed at every band, adjusts the levels of the mixed signals of the respective bands based on the adjusting amount, adds the adjusted signals of the respective bands and outputs it as a mixed audio signal.

L'invention porte sur un mixeur de signaux audio qui peut être appliqué à un dispositif de DJ et analogue, par exemple. Le mixeur de signaux audio acquiert une pluralité de signaux audio et acquiert des informations de proportion de mixage, qui sont des informations sur une proportion de mixage d'une pluralité des signaux audio. Le mixeur de signaux audio décide d'une quantité d'ajustement d'équilibre entre des niveaux, au niveau de chaque bande, lorsqu'une pluralité des signaux audio sont mixés sur la base de la proportion de mixage. Une pluralité des signaux audio sont mixés au niveau de chaque bande, le dispositif ajuste les niveaux des signaux mixés des bandes respectives sur la base de la quantité d'ajustement, additionne les signaux ajustés des bandes respectives, et délivre la somme en tant que signal audio mixé.

 オーディオ信号混合装置は、例えば、DJ機器等に適用することができる。当該オーディオ信号混合装置は、複数のオーディオ信号を取得するとともに、当該複数のオーディオ信号の混合割合に関する情報である混合割合情報を取得する。オーディオ信号混合装置は、複数のオーディオ信号をその混合割合に基づいて混合したときにおける帯域毎のレベル間のバランスの調整量を決定する。そして、複数のオーディオ信号を帯域毎に混合し、混合した各帯域の信号のレベルを調整量に基づいて調整し、調整語の各帯域の信号を加算して混合オーディオ信号として出力する。
