    Abstract: 본발명은보컬을포함하여여러악기음원이혼합된음악신호에서, 패닝기법을통해방향성을가지고있는음원위치의검출방법및 장치에관한것으로, 본발명에따른가중평균을이용한음원위치검출방법은입력된스테레오신호를 PCA(Principle Component Analysis) 기법으로주성분과주변성분으로분리하여상기스테레오신호의주성분에대한고유벡터를추출하는단계; 상기추출된고유벡터를이용하여상기스테레오신호의대역별음원위치를추출하는단계; 및상기스테레오신호의대역별에너지를이용하여상기추출된음원위치의정확도에따른가중평균을산출하는단계를포함한다. 본발명에따르면음원객체의위치추정정확도를향상할수 있기때문에다음원음악신호에서음원객체별위치를보다정확하게구현하여주며, 종래기술에사용하는균일평균방식을사용하지않고추정 SNR과밴드별에너지를이용하여효과적으로음원객체위치추정정확도를향상할수 있다. 또한, 다양한종류의음악에대하여음원객체의위치를추정함에따라음원객체별재 배치가가능하다.

    Abstract translation: 本发明涉及一种通过使用平移技术来定位具有方向性的声源的方法和装置,该声源从包括乐器的声乐和声音在内的各种声源混合的音乐声音信号。 根据本发明的使用加权平均定位声源的方法包括通过使用主成分分析将输入立体声信号分离成主要分量和环境分量,并且相对于主分量提取特征向量; 通过使用提取的特征向量来确定每个频带的立体声信号中的声源的位置; 以及通过使用立体声信号中的每个频带的能级,根据所确定的位置的精度来计算加权平均值。 根据本发明,由于可以通过使用每个频带的估计SNR和能级而不是常规方法中使用的均匀平均方案来提高声源对象的位置估计精度,音源中的声源对象的位置 可以更精确地确定具有各种声源的声音信号。 此外,由于声源对象相对于各种音乐被定位,因此可以执行每个声源对象的重排。

    Abstract: PURPOSE: A humming based audio searching system and method thereof are provided to enable a user to search desired sound by comparing user humming with sound stored in a data base. CONSTITUTION: A feature extraction apparatus(120) extracts feature information by inputting humming. A matching apparatus(130) respectively calculates matching values between the humming and a sound source stored in a database by using a pitch based LS(Linear Scaling), a pitch base DTW(Dynamic Time Warping), and a QB(Quantized Binary) code based LS method. A combination apparatus(140) calculates integrated values by applying multiplication to the matching values. A searching apparatus(150) searches the sound source similar with the humming by using the integrated values.
