Making accompaniment - teach you to use CE to eliminate the original singers in the song

Many friends have been asking how Only then can the sound in the original song be eliminated. Here I have sorted it out and will give you a systematic and detailed introduction to how to use Cool Edit Pro to create accompaniment tapes. As long as you have the original audio file of the song, you can quickly create an accompaniment tape. Here I will only talk about eliminating the original singer and ensuring the quality of the accompaniment to the maximum extent. But first of all, what I want to explain is: methods are always dead. If you don’t experience them carefully, even if you memorize the methods thoroughly, it will not be of much use. I am only introducing it to you here, not to teach you mechanically. If you really want to make something decent, you have to practice and experience it more. Therefore, I personally do not recommend everyone to use this method.

Secondly, no matter how you do it, the method introduced here cannot fully achieve the effect of the original version. Generally, some of the original singing sounds will remain, and some may not be able to do anything. Next, I will start from the basics. If you have the patience to read it carefully, it may be of great help to you.

1. Why can the original song be deleted?

Suppose there is an audio file in our computer, whether it is MP3, WMA or WAV. Usually an audio file is a song. , when we listen to it with our ears, there are usually original singers and accompaniments in a song. The characteristics of the original singer can be roughly divided into two types: 1. The sound image position of the human voice is in the center of the entire sound field (balanced distribution of left and right channels); 2. The sound frequency is concentrated in the mid-frequency and high-frequency parts. After we understand this, we only need to tell the computer to "eliminate the equal sounds of the left and right channels with frequencies concentrated in the mid-frequency and high-frequency parts." Therefore, the computer is always dead and is completely different from the human brain. He only follows orders and executes them. So once again I warn everyone that computers or software are dead. They are always tools, things that operate according to your thinking. If you want to use it to make decent things, you still have to use your brain in the end.

2. Which software can eliminate original songs

There are many software that can eliminate original songs. I personally know of Cool Edit Pro, T-RackS, Vogone, Dart Karaoke, WinRIP, etc. I won’t introduce them one by one here. In general, although the effects produced by each software are different, they all fall short of the ideal results. Cool Edit Pro is not an automated software. The most important thing is that you listen to it yourself and then give it commands so that it can help you achieve what your brain needs. If you are interested, you can also search for the following and try them one by one, depending on your needs. Here I will only introduce to you the noise reduction production of Cool Edit Pro and T-RackS.

3. The basic method of using Cool Edit Pro to eliminate the original singing

The method of using Cool Edit Pro to eliminate the original singing can actually be said to be very simple, but if you want to make it very Perfection still requires some effort.

The "Eliminate Original Singer" I am talking about here is just an independent function in the Cool Edit Pro menu. Select and use it and the results will be available immediately. But if you want to get the best results, just using the "Eliminate Original Singer" menu function of Cool Edit Pro is not enough! ! You still have to do a lot of detailed audio processing and settings.

In any case, let us try the simplest method of "eliminating the original song" first.

First enter the "Single Track Editing Mode" interface. Use "File" → "Open" to load an audio file. I have taken "Destined" by Yu Chengqing as an example, and the file name is "Destined.MP3". After tuning in, select "Effects" → "Amplitude" → "Channel Mixer...." (the Chinese version is "Effects" → "Waveform Amplitude" → "Channel Mixer"), and select "Presets" Vocal Cut" see (Figure 1), keep the default settings on the dialog box, and click the "OK" button.

After processing, the accompaniment music of the song "Destined" was obtained. The principle of the "Vocal Cut" function is to eliminate all sounds (including vocals and part of the accompaniment) whose sound image position is in the center of the sound field. Therefore, the main thing to use this function is to look at the source of the accompaniment and whether there are musical instruments and vocals placed in the center of the sound field before mixing. If there are, using this function will eliminate them, resulting in attenuation of the sound quality. For example, generally the sound field placed in the center includes "main voice", BASS... and so on. If the audio source you need to mute is the source of the principles I mentioned, I still recommend not to use this function. In this way, the human voice will not be eliminated and the accompaniment music will be eliminated, which is really depressing

Okay, let’s try out your results! Listen very carefully and you will notice that the accompaniment sounds different from the original soundtrack. The original singer's voice in the accompaniment tape has become very "virtual", but the original singer's voice can still be vaguely heard. In fact, this is the so-called silencing effect (it is absolutely impossible to eliminate the original singer). This accompaniment effect can basically be used as karaoke background music. When you sing, your cow-like roar is enough to cover up the original singer's voice. If you are not a friend who requires very original accompaniment, this should still work, hehe. (I'm not finished here yet!)

In addition, the audio quality throughout the entire accompaniment tape has declined, and what we hear is a lack of three-dimensional accompaniment sound (similar to mono audio ), there may also be some "sizzling" sounds, and the low frequency part has also been weakened a lot. All in all, it sounds very unpleasant.

Perhaps you are very dissatisfied with this effect now, aren't you? Don’t worry, let’s learn some advanced processing techniques. Please pay attention to the idea of ????the “silencing principle” I mentioned earlier.

4. Advanced Cool Edit Pro erasure

First, let’s summarize the results that we are not satisfied with. First, the sound of the original singer seems not clean enough; second, there is a "sizzling" noise; third, the stereo effect is reduced; fourth, the low-frequency effect is weakened.

The above four problems will be corrected one by one below. Start by opening the "Destined.MP3" soundtrack in Cool Edit Pro.

1. Eliminate the original vocal sound more cleanly

Select "Effects" → "Amplitude" → "Channel Mixer...." (the Chinese version is "Effects" → "Waveform Amplitude" → "Channel Mixer..." "Shrink"), select "Vocal Cut" in "Presets". Previously we dealt with the default values, now we try to adjust the various parameters on the left (Figure 2). During the adjustment process, you can click the "Bypassa" checkbox at any time to compare the original sound.

There are two "Invert" checkboxes on the left. By default, one of them has a "√" in front of it. Now we cancel the "√" and the sound becomes "dry", but The sound field becomes wider and the three-dimensional effect is enhanced, but the low frequencies are reduced more. Maybe this effect is more suitable for some songs, but it is not very effective for some songs. When processing, you still have to debug it slowly and carefully. If this method is not good for the song you want to process, naturally keep the default set up.

Under the default settings, this dialog box is already in a state to eliminate the original sound to the greatest extent. Therefore, if you want to eliminate the original sound more cleanly, there is basically no way here. I personally find that songs sung by different people have different effects on the original singer. Some are better, some are far from ideal. But we can optimize this processing through the four sliders on the left side of the "Channel Remix" dialog box (see Figure 2). Since the final effect is greatly affected by the original soundtrack, there is no fixed "set" for the adjustment here. You can only move the slider slightly to the center point. The stereo effect will be more obvious, but the vocals will also become more obvious. When it comes to stereo and vocal cancellation effects, you have to compromise on one side. Here, the processed result is first saved as "Destined (accompaniment).MP3".

2. Eliminate the "sizzling" sound

Noise comes from two places, here I am referring to the noise in the accompaniment. First, your original soundtrack has undergone lossy compression (such as MP3 or WMA encoding), which will naturally appear after the "channel remixing" process; second, the clean breath and sibilance have not been eliminated. .

Therefore, if conditions permit, the CD audio track should be directly saved to the hard disk in WAVE format for processing.

To eliminate the "sizzling" sound, you generally need to use the "equalizer" function of Cool Edit Pro. First, load the accompaniment "Fated (Accompaniment).MP3" that has just been eliminated, and select "Effects" → "Filters" → "parametric Epualizer" (Chinese is "Effects" → "Filter" → "Parametric Equalizer") . This "parametric equalizer" is not very intuitive for beginners. Friends who don't know much about equalizers can also choose to use the "graphic equalizer" to adjust it. Its operation interface is much more intuitive and easier than the "parametric equalizer" . Here I use the "parametric equalizer" to eliminate the "sizzling" sound in the accompaniment.

The function of "equalizer" is to enhance or attenuate the sound intensity of a certain frequency range or several frequency ranges. The "sizzle" sound is usually around 8000Hz. We attenuate the sound intensity in this area (see Figure 3).

This processing also helps to further eliminate human voices. For example, the frequency response of the general human voice is dominated by the intermediate frequency, and we can appropriately attenuate the intermediate frequency part. Breathing sounds and sibilant sounds are mainly above 6000Hz - 18000Hz. They can also be attenuated according to the actual situation, but the clarity of the accompaniment will be lost. The equalizer is generally used for repair and optimization. To eliminate the human voice, you have to go to "Effect" → "Waveform Amplitude" → "Channel Remix". Don’t forget to save when you’re done here!

3． Stereo effect enhancement

Stereo effect enhancement is a relatively professional processing method. Since it cannot be fully written out at the moment, I will only briefly talk about the stereo enhancement method. You can use stereo effect enhancement plug-ins (such as: WAVES Plug-in effect equipment is a good processing plug-in, I will not introduce them one by one here) or use professional stereo enhancement software to make appropriate adjustments, and you can also add some reverberation effects appropriately.

4. Low-frequency compensation

"Destined (accompaniment).MP3" is the result after we eliminated the original vocals and the "hiss" sound, but its audio was attenuated a lot. To compensate for the low frequency, you can use Cool Edit Pro's "Equalizer" here, but do not use this file that has been "eliminated" because its low-frequency effect has been attenuated. If you perform gain processing, the effect will definitely not have the original soundtrack. Okay, so we're working with the soundtrack. Take out the low-frequency part of the original soundtrack as compensation for the accompaniment.

Now first tune in the "Destined.MP3" soundtrack, select "Effects" → "Filters" → "parametric Epualizer" (Chinese is "Effects" → "Filter" → "Parametric Equalizer") , after entering the "Parametric Equalizer", adjust the parameters to look like Figure 4. Click "OK" to process immediately, so that you can get the low-frequency part of the "Destined" soundtrack. Here, save the file as "Destined (BASS).MP3" for now. (Remind everyone again, it is best to save in lossless WAV format from the beginning, so that the final effect will be better.)

5. Multi-track synthesis

I don’t need to say more about multi-track synthesis. You must be familiar with it. Here, first insert the silenced "Destined (accompaniment).MP3" into the first track; "Destined (BASS).MP3" is inserted into the second track, and the mixing is done. If you feel that the volume of the two audio tracks is not very balanced, you can adjust the volume of the next two audio tracks in multi-track mode until you hear the accompaniment is full and suitable, then mix and save it.

The focus of human voice elimination is actually to strike a balance between the degree of human voice cancellation and the playback effect. If the playback effect is not considered, the human voice can be eliminated more cleanly, but it is not necessary to do so. As long as your voice covers the original song when you sing, it's fine. In this way, the effect of the accompaniment tape can be guaranteed, and the sound of the original singer will not be too obvious.

I would like to warn everyone here that I personally recommend this method only for reference and study, and do not expect it to bring you any good results.

Also, the use of this method mainly depends on the source of the songs you want to silence. Not all songs can be eliminated. It must first meet the principles and conditions I mentioned earlier. Don’t blame yourself for poor results. Don't blame yourself or others, or your own pretentiousness or the device's sound card or anything like that. Because the production of these methods has nothing to do with the equipment, the quality of the effect is by no means caused by the badness of your equipment. The most important role of the sound card in producing the effects here is to output the sound so that you can get good or bad results. In the end, it’s up to you to experience it carefully.

Finally, I hope everyone can have fun and learn in WO99. The most important thing is that you can learn more things, whether it is hardware, software operation, recording or effect production. A big breakthrough
