SIGNAL PROCESSING DEVICE FOR PROVIDING STEREOSCOPIC SOUND EFFECT AND A METHOD THEREOF FOR DIVIDING AN INPUT SIGNAL INTO A PRIMARY SIGNAL AND AN AMBIENCE SIGNAL

摘要

PURPOSE: A signal processing device for providing stereoscopic sound effect and a method thereof are provided to add an ambience signal and a primary signal by removing the correlation of the ambience signal, thereby generating an output signal which sound effect is applied.;CONSTITUTION: A signal processing device(100) includes a mask determining unit(101), a signal dividing unit(102), a correlation removing unit(103), and a signal generating unit(104). The mask determining unit determines a mask related to ambience of an input signal. The signal dividing unit divides the input signal into a primary signal and an ambience signal by using the mask. The correlation removing unit removes the correlation of the ambience signal. The signal generating unit generates an output signal which sound effect is applied by adding the ambience signal and the primary signal.;COPYRIGHT KIPO 2013;[Reference numerals] (101) Mask determining unit; (102) Signal dividing unit; (103) Correlation removing unit; (104) Signal generating unit; (AA) Input signal(stereo signal); (BB) Ambience signal; (CC) Primary signal; (DD) Output signal
