Description: 采用滤波器组，将盲分离与声源定位结合在一起。滤波器组中分别进行子带处理，并且在每个子带中进行声源定位，最后综合所有子带估计的方向得到多个声源的方位信息，同时将声源信息作为ICA分析的约束条件，可以在色噪声及多得到更好的盲分离效果。其优势在于用滤波器组进行多次的估计声源方向，再加以合适的权值均衡后即可得到更优的估计。-The use of filters will be blind source separation and sound localization together. Filter group were sub-band treatment, and in each sub-band in Sound Source Localization, and finally all the sub-band is estimated to be more than the direction of sound source location information, as well as sound source information as ICA analysis of the binding conditions, colored noise can be better and many of the blind source separation effect. Its advantage lies in a number of filter banks with estimated sound source direction, coupled with an appropriate balance weights can be obtained after the better estimate. Platform: |

Description: ac3标准文档，杜比数字AC-3（Dolby Digital AC-3）是杜比公司开发的新一代家庭影院多声道数字音频系统。杜比定向逻辑系统是一个模拟系统。它的四个声道是从编码后的两个声道分解出来的，因此难免有分离度不佳、信噪比不高，对环绕声缺乏立体感，并且环绕声的频带窄等缺点。-ac3 standard documents, Dolby Digital AC-3 (Dolby Digital AC-3) is Dolby has developed a new generation of home theater multi-channel digital audio system. Dolby Pro Logic system is a simulation system. It is from the four-channel encoded by the two-channel decomposition, have poor separation, signal to noise ratio is not high, on three-dimensional sense of a lack of surround sound and surround sound, such as the shortcomings of a narrow band.
