通过BF561双核处理系统，对输入的音乐进行实时的处理，将歌声消除并顺利的提取背景音乐。共采用了3种方法来实现歌声的消除，主要是左右声道相减、滤波消除以及两者结合在一起的综合消除。通过实际的硬件测试，证明3种方法都有消除人声的功能，但左右声道相减、滤波消除说得到的结果不是很理想，而两者结合起来的最终结果在消除歌声和背景音乐提取方面得到了很好的结果。-Through the BF561 dual-core processing system, to enter the music in real-time processing, will be singing and the smooth extraction of the elimination of background music. A total of three kinds of methods used to achieve the elimination of singing, the main channel is about subtraction, filtering, as well as the elimination of a combination of both integrated together to eliminate. Through the actual hardware tests to demonstrate that there are three kinds of methods to eliminate the function of the human voice, but the left and right channels subtraction, filtering to eliminate results that are not very satisfactory and the combination of the final results in the elimination of songs and background music extract received very good results.
