Apparatus and method for removing vocal signal

PURPOSE: An apparatus and method for removing a vocal signal are provided to maintain a three-dimensional effect applied to a stereo signal in an output signal from which a vocal signal is removed by correcting a difference signal between a right signal and a left signal. CONSTITUTION: A vocal signal removing device(100) comprises an extracting unit(110), an information acquisition unit(120), and an output unit(130). The extracting unit, the information acquisition unit, and the output unit are formed with a microprocessor. The output unit includes a speaker which outputs an audio signal. The extracting unit extracts the difference signal between an input right signal and an input left signal. The information acquisition unit obtains left panning information from the input left signal. The information acquisition unit obtains right panning information from the input right signal. The output unit generates the output left signal by applying the left panning information to the input left signal. The output unit generates the input right signal by applying the right panning information to the output right signal.
