The sampling de-noising method is a method for professional audio processing software to effectively remove the continuous stable background noise. The principle of de-noising is to sample the waveform samples of the noise, and then analyze the waveform and sampling noise samples of the entire material to automatically remove the waveform noise. The advantage of this noise removal is that the noise can be completely removed. The disadvantage is that it has a destructive effect on the original human voice quality, and the signal-to-noise ratio is more destructive. After this de-noising, the sound of the metal is very strong. Therefore, this method is generally not recommended to de-noise the singing voice.
