Abstract: PURPOSE: A device and a method of editing a multi-channel audio signal are provided to generate a multi-channel audio signal with 3D effects. CONSTITUTION: An output position determining unit (120) determines a position to which an object audio signal is outputted by using edit information of the object audio signal. A multi-channel object audio signal generating unit (130) generates a multi-channel object audio signal by allocating the object audio signal to a channel corresponding to the position to which the object audio signal is outputted. A multi-channel audio signal conversion unit (110) converts a first multi-channel audio signal into a second multi-channel audio signal corresponding to the multi-channel object audio signal. An audio mixing unit (140) generates a third multi-channel audio signal by mixing the multi-channel object audio signal to the second multi-channel audio signal. [Reference numerals] (100) Multi-channel audio signal editing device; (110) Multi-channel audio signal conversion unit; (120) Output position determining unit; (130) Multi-channel audio signal generating unit; (140) Audio mixing unit
