无法消除原声中人声的道理（Can not eliminate the original voice of the truth） Can not eliminate the original voice of the truth Many friends have tried to get rid of the voices of a song or a piece of film, but in any case can not get satisfactory results, but not reconciled, always try to eliminate the voice. Here, I advise you not to waste energy, will want to completely eliminate the vocals from the original songs or films, the remaining sound is not possible, at least to the current level of science and technology is very difficult to achieve. Here, a brief explanation of the principle of the elimination of human voices, we are most familiar with the elimination of human voices, presumably the Cool Edit inside the Vocal Cut? Lets talk about it here, whether its Vocal, Cut, or any other human voice software or plug-in that uses one principle: the left and right channel stacking of two channel stereo. It involves a bit of knowledge: Phase, phase, a friend who doesnt know much about it, search the Internet for sound phase, and see its concept. When a double track stereo left and right channel sound exactly the same, but the waveform phase difference of 180 degrees, left and right channel phase will be completely offset, so when we use Vocal Cut in a single channel audio, the result is the volume of 0 wave, because single channel about the sound is the same, flip one side and the other side phase superposition, the nature is completely offset the results. This simple principle is the elimination of the human voice, in a song, because people are often in the middle, so very close to the single channel, and after the phase reversal of superposition, the vocals can be eliminated, but this is eliminated, you will meet two questions: First, the voices are not clean, and there are some remnants. Listen carefully to what remains of the rest of these sounds. Yes, thats the reverb of the human voice in the original music! Why is the voice itself cancelled, and the reverberation of the hum
