Abstract:
PURPOSE: A method for matching objects between sound sources and a device thereof are provided to decode other sound sources in reproducing object based sound sources and preprocess the other sound sources when objects of the object based sound sources are matched. CONSTITUTION: A device for matching objects between object based sound sources receives a matching target sound source and an object(S210). The device adjusts the speed of other objects included in other sound sources according to a reference object of set reference sound sources(S220). The device adjusts the lengths of sound sources of the speed-controlled other objects(S230). The device matches the objects(S240).
Abstract:
PURPOSE: An up-mixing method for converting a stereo channel input signal into a multichannel output signal and an apparatus thereof are provided to apply a sound source separation technique in a stereo signal itself, thereby maintaining spatial properties including sound sources during a mixing process of a multichannel signal. CONSTITUTION: An up-mixing apparatus divides an input signal of a stereo channel into a plurality of sub-bands in a frequency range(S210). The sub-band with a highest mutual correlation is selected as a representative sub-band by measuring a mutual correlation between two channels of a stereo input signal(S220). A sound source level difference value between estimated two channels is determined as a first sound image fixing level difference value by analyzing the stereo input signal(S230). A sound image fixed sound source signal and reverberation signal are separated(S240). A sound image fixing level difference value is calculated with respect to a front channel of a multichannel speaker output system(S250). The up-mixing apparatus synthesizes the separated sound image fixed sound source signal and reverberation signal into a multichannel output signal(S260).
