Cool edit pro How to eliminate the original singing

As long as there are songs of the original singing audio files, can be quickly made into accompaniment.

Can eliminate the original to sing a lot of software, and produced the accompaniment is also different, but are not up to the ideal effect. The elimination of the original singing after the accompaniment can not fully achieve the original accompaniment effect, the general will remain part of the original singing voice, and some audio will be damaged. So what we are introducing is to eliminate the original chorus to maximize the quality of accompaniment. But if you want to get a higher quality accompaniment, you have to rely on our own a lot of practice and groping.

Here we only on the introduction of CE. CE is not automated software, so the effect of audio processing, the most important thing is to rely on everyone to listen to. If you are interested, you can spend a lot of time exploring experience to achieve the sound quality you want.

In any case, I still hope that this method will bring a little help to everyone.

One, why can eliminate the original singing

Let's say we have an audio file on our computer, whether it's MP3, WMA or WAV, which is usually a song. We heard a song with the original singing, accompaniment. And the characteristics of the original singing is broadly divided into two: 1, the voice of the audio-acoustic position in the entire sound field of the central (balanced distribution of left and right channels); 2, the sound frequency concentration in the intermediate frequency and the high-frequency part. After reading these, we know to be "left and right channel of the equivalent sound and frequency concentration in the intermediate frequency and high-frequency part of the sound" eliminate.

The basic method of eliminating original singing with cool Edit Pro

The "Elimination of original singing" is usually the "silencing" we see.

With the CE to eliminate the original singing, the method is actually very simple, but want to improve its sound quality or to be a little bit of effort oh.

What we call "silencing" here is only an independent function in the CE menu, the choice and use will have the result immediately. But for better results, more detailed audio processing and tuning are needed. OK, below is a detailed implementation step.

1, first into the CE "monorail" editing mode interface. "File" → "open" to transfer an audio file. Here in the case of Yu-Qing's "fate", the file is named "doomed. mp3".

2, open the audio after selecting "effect" → "waveform amplitude" → "channel heavy mixing shrink", in the open window to select "Preset" inside the "vocal cut" see (Figure 1), to keep the dialog box on the default settings, click "OK" button. After the CE treatment, it was "doomed" this song accompaniment music.

3. The functional principle of "vocal cut" is to eliminate all sounds (including vocal and partial accompaniment) in the center of Sound field in the audio-acoustic position. So whether you can use this function only to eliminate the original singing voice, mainly to see the source of the original singing audio, in the mix before whether there are instruments and vocals in the center of the sound field, if any, use this function will be removed together, resulting in a great quality of attenuation. For example, the General sound field in the center of the "Master Voice", "BASS" and so on. If the original song audio source is said above, it is recommended not to use this function, so that the voice did not eliminate the accompaniment of music will be eliminated.

4, OK, try to listen to their own achievements! Listen carefully, you will find that the accompaniment is different from the original singing band. Accompaniment in the original singing voice has become very "virtual", but vaguely still can hear the original singing sound, in fact, this is called "silencing" after the effect (absolute elimination of the original singing is impossible). This accompaniment is good as a karaoke background music, when you sing enough to cover up the original voice. If it is not very demanding the original accompaniment of friends, this should be able to take the battle.

5, in addition, the entire accompaniment band in the audio quality has declined, we heard is the lack of three-dimensional accompaniment sound (similar to mono audio), there may be some "hissing" sound, low-frequency parts are also weakened a lot. Anyway, it sounds bad. Perhaps you are already very dissatisfied with this effect, then we will learn some advanced processing techniques.

Third, cool Edit Pro fade sing advanced

Let's summarize what we are not satisfied with. First, the sound of the original singing seems to have not been clean enough; second, there is a "hissing" murmur; third, the stereo effect is reduced; four, the low-frequency effect is weakened. The following one by one amendments are made to the above four questions.

1, remove the original singing sound more clean

First in the CE monorail Open "doomed. mp3" Original singing band. Select "Effect" → "waveform amplitude" → "Channel repeat", in the open window select "Preset" inside the "vocal cut". Previously we were dealing with the defaults, and now we're trying to adjust the parameters on the left. See (Figure 2).

In the adjustment process, you can point to the "passthrough" check box to compare the original sound.

The left side has two "inverse" checkbox, the default state one of the front has "√", now we Remove "√", the sound becomes more "dry", but the sound field has become more open, three-dimensional enhancement, but the low-frequency is reduced more. Perhaps this effect on some songs more appropriate, but the effect of some songs is not very good, processing time or rely on everyone to slowly, careful debugging. If this method is not good for the songs you're dealing with, keep the default settings.

This dialog box is already in the state of minimizing the original sound by default, so there is no way to eliminate the original sound even more cleanly. Different people sing songs, the effect of the original singing is not the same OH. Some would be better, some would be very unsatisfactory. However, we can optimize this process through the four sliders in the "Channel Redo" dialog box. Because the final effect by the original singing band effect is very large, so there is no fixed parameter adjustment, can only move the slider slightly to the center point, the stereo effect will be more obvious, but the human voice will become more obvious. In stereo and vocal elimination, one has to compromise on one side. Here first the result of the processing is saved as "predestined (accompaniment). mp3".

2, eliminate "hissing" sound

The murmur comes from two places, where we are referring to the noise in the accompaniment. First, your original singing band after the lossy compression processing (such as MP3 or WMA coding), after the "channel weight mixing shrink" treatment, the natural will appear, and second, not eliminate the clean air and teeth sound. So the condition allows, the CD track can be saved to the hard disk in WAV format directly and then processed.

Eliminate the "hissing" sound generally to use the CE "Equalizer" function. First transferred into the "mute" after the accompaniment of the fate (accompaniment). mp3 ", select" Effect "→" filter "→" Parameter Equalizer ". This "parameter Equalizer" for beginners is not very intuitive, here is not very understanding of the equalizer friend can also choose to use the "graphic equalizer" to adjust, its operating interface than "parameter equalizer" intuitive much easier. Here we use "parametric equalizer" to eliminate the "hissing" sound in the accompaniment.

The function of "equalizer" is to enhance or attenuate the sound intensity of a certain frequency segment or some frequency segment. The "hissing" sound is usually around 8000Hz, and we use this area's sound intensity as a attenuation process. See (Figure 3).

This process also helps to further eliminate the human voice. For example, the frequency response of the general human voice is mainly medium frequency, we can do appropriate attenuation of the if part. But the air sound and the tooth sound mainly in 6000hz-18000hz above, may also do the attenuation processing according to the actual situation, but may lose the accompaniment the clarity. Equalizer is generally used to do repair and optimization, the elimination of the human voice must rely on the "effect" → "waveform amplitude" → "channel heavy mixing shrink" to do. Don't forget to save it when you've finished with it!

3, Stereo effect enhancement

"Stereo effect Enhancement" belongs to the more professional processing technique, because covers a wider area, here we simply introduce under "Stereo enhancement" method. You can use the stereo enhancer enhancements (such as the Waves plug-in effect) to be a good processing plugin. or with professional "stereo enhancement software" for appropriate adjustment, you can also add some reverberation effect.

4. Low Frequency compensation

"Fate (Accompaniment). mp3" Is the result of eliminating the original singing and eliminating the "hissing" sound, but its audio has been attenuated a lot to compensate for the low-frequency. Here you can use the CE "equalizer", but do not use the "silencing" of this file, because its low-frequency effect has been attenuated, if the gain processing, the effect must not be the original singing with good, so we use the original sing brought to deal with. Take out the low-frequency part of the original singing band as the accompaniment compensation.

Now, let's move into the "Destiny. mp3" Original singing band, select "Effect" → "filter" → "parameter Equalizer", into the "parameter Equalizer", the parameters adjusted to (Figure 4) look. The point "OK" immediately after processing, so you can get the "doomed" soundtrack in the Low-frequency section, here temporarily save this file as "doomed (BASS). mp3". (To remind you again, save the best from the beginning of the use of lossless WAV format to save, so that the final results will be better.) )

5. Multi-orbit synthesis

This is needless to say, you must be very familiar with, here first the mute OK "predestined (accompaniment)." MP3 "inserted into the first rail;" Fate (BASS). mp3 "inserted into the second rail, mixed condensation achievement OK." If you feel that the volume of two tracks is not very balanced, you can adjust the volume of two tracks by "adjusting the audio block volume" Under Multiple rails before you mix, until you listen to the accompaniment and then make the blending.

This method only does the reference and the study, does not necessarily achieve the most ideal effect oh. The focus of the elimination of the human voice is actually in the human voice to eliminate the degree and play the effect of achieving balance, if not consider playback effect, the human voice can be eliminated more clean, but this is not necessary to do, as long as your voice in singing can cover the original singing on it. In this way the effect of the accompaniment can be guaranteed, the original singing voice is not too obvious. The use of this method, mainly to see you mute the source of the song, not any songs can be silenced. It must first have the above mentioned principle conditions, followed by the late audio processing process. Finally, we have to rely on our own to explore and experience.
