A surround signal generating device generates surround signals of plural channels from input sound signals of two channels, and is preferably applied to an audio device, for example. A setting unit sets a correlation value between channels in the plural channels and/or a level difference of the plural channels, in accordance with a genre of a content. A surround signal generating unit generates the surround signals of the plural channels based on the correlation value and/or the level difference which are set by the setting unit. Therefore, it becomes possible to appropriately generate the surround signals having the correlation value and/or the level difference between the channels which are appropriate for the genre of the content, from a stereo sound source. |
