Audio music decision device, audio music decision manner and program for audio music decision

摘要

Topic This invention makes that proportion of the aural signal and the music signal which are included in the audio signal which it should regenerate is distinguished quantitatively with high reliability possible, designates that robust Characteristic of distinction is raised especially, vis-a-vis the aural signal where the background sound which is easy to cause identification error is superimposed as purpose. SolutionsIt calculates various feature parameters in order to distinguish with sound and music from the entry audio signal, it grants the significance coefficient which is based on the parameter value of the access data for audio music which, studied beforehand it calculates as the score S1 which displays the precision of the music aural signal. In the same way, it calculates various feature parameters in order to distinguish with music and the aural signal where background sound is superimposed from the entry audio signal, it grants the significance coefficient which is based on the parameter value of the access data for music background sound, it calculates as the score S2 which displays the precision of the music background sound being superimposed aural signal.
