Description: 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.
