How to eliminate human voice in poetry recitation? I've already used cool edit pro, and vocal music is useless, only useful for songs. I'm here.

This paper systematically introduces the whole process of recording self-singing songs with Cooledit pro 2. 1, hoping to help friends who like singing and want to show their voices.

Record the original sound

Recording is the basis of all post-production and processing. If something goes wrong in this link, it can't be remedied by post-processing. So, if there is a big problem with the original recording, re-record it.

1. Open CE to enter the multi-channel interface, right-click on the blank space of 1 channel, and insert the mp3/wma accompaniment file of the song you want to record (Figure 1).

(Figure 1)

2. Select to record your voice on track 2, and then press the "R" button. (Figure 2)

(Figure 2)

3. Press the red recording button at the lower left to start singing and recording with the accompaniment music. (Figure 3)

(Figure 3)

4. After the recording is completed, you can click the play button at the lower left to audition to see if there are any serious errors and whether to re-record (Figure 4).

(Figure 4)

5. Double-click track 2 to enter the waveform editing interface (Figure 5), and save the original sound file you recorded as mp3pro format (Figures 6 and 7). In the previous introduction, you were asked to save it in wav format. In fact, wma/mp3 is completely possible, and it can save a lot of space.

(Figure 5)

(Figure 6)

(Figure 7)

(Note) First of all, it is very important to turn off the speakers when recording, listen to the accompaniment through headphones, sing along with the accompaniment and record, and adjust your total volume and microphone volume before recording! It's best not to exceed the total volume of the microphone, and lower it a little, because the microphone volume is too high, the recorded waveform will become a square wave, the sound of this waveform will be distorted, and this waveform will be useless. No matter how high your level is, you can't handle satisfactory results.

In addition: if your microphone keeps recording the sound of accompaniment music from headphones, I suggest you use an ordinary big microphone and add a big connector to use it directly on the computer. You will find that the recorded effect is much cleaner.

Noise reduction is a crucial step. Doing a good job is conducive to further beautifying your voice below. If it is not done well, it will lead to sound distortion and completely destroy the original sound. This step alone is enough to create a space for special explanation, as long as everyone knows this.

1. Click the waveform horizontal amplification button at the lower left (the two with+signs are horizontal amplification and vertical amplification respectively) to amplify the waveform and find the waveform suitable for noise sampling (Figure 8).

(Figure 8)

2. Click the left mouse button and drag until the highlighted area completely covers the waveform you selected (Figure 9).

(Figure 9)

3. Right-click the highlighted area and select Copy as New to extract the waveform (Figure 10).

(Figure 10)

4. Turn on "Effect-Denoising-Noise Reducer" to prepare for noise sampling (Figure 10).

5. Conduct noise sampling.

The parameters in the noise reducer can be set to the default values or changed at will, which may lead to great noise distortion (Figure 1 1).

(Figure 1 1)

6. Save the sampling results (Figure 12)

(Figure 12)

7. Turn off the noise reducer and this waveform (no need to save).

8. Return to the vocal file in the waveform editing interface, turn on the noise reducer, and load the noise samples saved before for noise reduction. Before you decide to reduce noise, you can preview the effect of noise reduction (if the distortion is too large, it means that noise reduction sampling is not suitable, and you need to resample or adjust the parameters. One thing to note is that no matter what noise reduction method is used, the original sound will be destroyed (Figure 13 Figure 14).

(Figure 13)

(Figure 14)

(Figure 15)

Triple excitation processing

1. Click "Effect-DirectX-BBE Sonic Maximizer" to open the BBE treble exciter (Figure 16).

(Figure 16)

2. After loading various effects in the preset drop-down menu (or completely manually adjusting the three knobs), click "Preview" at the lower right of the exciter to conduct repeated audition, and click OK to perform treble excitation on the original sound until satisfactory effects are achieved. (Figure 17 Figure 18)

(Figure 17)

(Figure 18)

(Note) The purpose of this process is to adjust the high-pitched and low-pitched parts of the recorded voice to make the sound clearer, brighter or richer. The function of excitation is to produce harmonics, modify and beautify the sound, and produce pleasant auditory effects. It can enhance the frequency of sound, improve clarity, brightness, volume, warmth and heaviness, and make the sound more tense.

Pressure limiting treatment

1. Click "Effect -DirectX-Waves-C4" to open the WaveC4 pressure limiting effector (Figure 19).

(Figure 19)

2. After loading various effects in the preset drop-down menu (if you know enough about digital audio, you can also adjust it manually), click "Preview" at the lower right for repeated audition, and click OK to limit the original sound until you adjust it to a satisfactory effect (Figure 20).

(Figure 20)

(Note) The purpose of pressure limiting, in layman's terms, is to make the sound you recorded balanced as a whole, so as not to be big and small, high and low.

Reverberation treatment

1. Click "Effect -DirectX-ultra funk FX- Reverberation R3" to open the Reverberation Effector (Figure 2 1).

(Figure 2 1)

2. After loading various effects (or manually adjusting) in the preset drop-down menu, click "Preview" at the lower right for repeated audition until the reverberation effect is satisfactory, and then click OK to reverberate the original sound. Common effects are shown in the figure (Figure 22 and Figure 23).

(Figure 22)

(Figure 23)

Reverberation can make your voice look less dry, rounder and richer.

At this point, the processing of human voice is all over.

Mixed contraction synthesis

1. Click "Edit-Mix to File-All Waveforms" to mix the accompaniment with the processed parts (Figure 24).

(Figure 24)

2. Click "File-Save As" to save the mixed file in mp3/wma format (Figure 25).

Teach you CoolEidt to eliminate human voice

Recently, many friends are asking how to eliminate the sound in the original song. Here I sorted it out and gave you a systematic and detailed introduction on how to make accompaniment tapes with Cool Edit Pro. As long as you have the original audio file of the song, you can quickly make it into an accompaniment tape. I'm only talking about eliminating the original sound and ensuring the quality of accompaniment to the greatest extent. But first of all, I want to explain that the method is always dead. If you don't understand it carefully, even if you recite it, it won't have much effect. I only introduce it to you here, not mechanically copy it for you. It takes more practice and experience to really make something decent. Therefore, I personally don't recommend you to use this method.

Secondly, no matter what you do, the method introduced here can't completely achieve the original effect. Generally, some of the original songs will be retained, and some may be powerless. Next, I will start with the basics. If a patient friend reads carefully, it may be of great help to you.

First, why can I cancel the original song?

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 with our ears, we usually have an original song and accompaniment. The characteristics of original singing can be roughly divided into two types: 1, and the audio-visual position of human voice is in the center of the whole sound field (balanced distribution of left and right channels); 2. The sound frequency is concentrated in the intermediate frequency and high frequency parts. After understanding this, all we have to do is tell the computer to "eliminate the equivalent sound of the left and right channels and the sound whose frequency is concentrated in the intermediate frequency and high frequency". Therefore, the computer will always be dead, completely different from the human brain, and will only listen to orders and execute them. So I warn you again that the computer or software is dead. They are always tools, things that follow your thinking. If you want to make something decent with them, you will have to use your head eventually.

Second, those softwares can eliminate the original songs.

There are many softwares to eliminate original songs, among which I personally know Cool Edit Pro, T-RackS, Vogone, Dart Karaoke, WinRIP and so on. I won't introduce it here. Generally speaking, although each software produces different effects, it can't achieve the ideal effect. For Cool Edit Pro, it is not an automated software. The most important thing is to listen to it yourself and then give it an instruction to help you realize what your brain needs. If you are interested, you can also search one of the following to try your own needs. Here, I will only introduce you to the silencing production of two softwares, cool editing Pro and T-RackS.

Third, the basic method of eliminating the original singing with Cool Edit Pro

In fact, it can be said that it is very simple to eliminate the original song with Cool Edit Pro, but if you want to be perfect, you still have to work hard.

What I'm talking about here is just a Li Du function in the cool editing professional menu. If you choose and use it, you will get the result immediately. But in order to get the best effect, it is not enough to just use the "Cancel Original Music" menu function of Cool Pro! ! You need to do more detailed audio processing and setting.

Anyway, let's try the simplest method of "eliminating the original song" first.

First enter the "Monorail Editing Mode" interface. Call in the audio file with File → Open. I take the fate of Yu Chengqing as an example. The file name is fate. MP3。 After calling in, select Effect → Amplitude → Channel Mixer (Chinese version means Effect → Waveform Amplitude → Channel Remixing), select Vocal Cut in the preset (see figure 1), and keep the default settings in the dialog box. Click ". After processing, the accompaniment music of the song "Destiny" was obtained. The principle of "sound interception" function is to eliminate all sounds (including human voice and some accompaniment) in the center of the sound field. Therefore, the use of this function mainly depends on the source of accompaniment, whether there are instruments and parts placed in the center of the sound field before mixing, and if there are, they will be eliminated by this function, resulting in the attenuation of sound quality. For example, there are "tonic", bass and so on in the center of the general sound field. If you need a mute sound source, which is the source of these principles, I still suggest not using this function, so that the human voice will be eliminated until all the accompanying music is eliminated, which is really depressing.

Ok, let's hear your own results! Please listen carefully, you will find that the accompaniment is different from the original sound. The original songs in the accompaniment band have become "empty", but the original songs can still be faintly heard. In fact, this is the so-called effect after noise elimination (it is impossible to completely eliminate the original song). This accompaniment effect can basically be used as the background music of karaoke. When you sing, your roar like an ox is enough to cover up the original song. If you are not a friend who asks for original accompaniment, this reason should still be ok, hehe. (I'm not finished here! )

In addition, the audio quality in the whole accompaniment band has declined, and what we hear is an accompaniment sound that lacks three-dimensional sense (similar to mono audio), and there may be some "hissing" sounds, and the low-frequency part has also weakened a lot. Anyway, it doesn't sound cool.

Maybe you are not satisfied with this effect now? Don't worry, learn some advanced processing skills first. Please pay attention to the "silence principle" I mentioned earlier.

Fourth, the cool editor Pro eliminates the advanced original singing.

Let's summarize the unsatisfactory results first. First, the voice of the original singer seems to be not clean enough; Second, there is a sizzling noise; Third, the stereo effect is reduced; Fourth, the low-frequency effect is weakened.

The following four questions are corrected one by one. First, open the soundtrack of "Destiny takes a hand.mp3" in the cool editor Pro.

1. Eliminate the original sound more cleanly.

Select Effect → Amplitude → Channel Mixer (Chinese version is Effect → Waveform Amplitude → Channel Mixing), and select vocal cutting in the preset. Previously, we used default values. Now, let's try to adjust the parameters on the left (see Figure 2). During the adjustment process, you can click the "Bypassa" check box at any time to compare the original sound.

There are two "Reverse" check boxes on the left. By default, one of them is preceded by a "√". Now we cancel "√", and the sound becomes drier, but the sound field becomes wider, the three-dimensional sense is enhanced, but the low frequency is reduced more. Maybe this effect is suitable for some songs, but it is not very good for some songs. When dealing with it, it is still necessary to debug it slowly and carefully. If this method is not good for the song you want to deal with, naturally keep the default settings.

screen . width-500)this . style . width = screen . width-500； } " border = 0 & gt

By default, this dialog box has been in the state of eliminating the original sound to the greatest extent, so there is basically no way to eliminate the original sound more cleanly here. Personally, I find that different people sing different songs. Some will be better, while others are far from it. However, we can optimize this process through the four sliders on the left side of the "Mixer" dialog box (see Figure 2). Because the final effect is greatly influenced by the soundtrack, there is no fixed "formula" for adjustment here. Only by moving the slider slightly to the center point will the stereo effect become more obvious, but the human voice will also become more obvious. We have to compromise on stereo and vocal cancellation. Here, the processing result is saved as "Destiny takes a hand (accompaniment) .mp3".

Step 2 Eliminate the "hissing" sound

The noise comes from two places, and here I mean the noise in the accompaniment. First, your soundtrack has been lossy compressed (such as MP3 or WMA coding) and will naturally appear after "sound mixing". Second, the clean air and the sound of teeth have not been eliminated. Therefore, if conditions permit, CD tracks should be saved directly to the hard disk in WAVE format for processing.

In order to eliminate the "hissing" sound, the "equalizer" function of Cool Edit Pro is generally used. First tune the just-eliminated accompaniment "Destiny takes a hand (accompaniment) .mp3" and select "Effect → Filter → Parameterized Epulizer" (Chinese is "Effect → Filter → Parameterized Equalizer"). This "parameter equalizer" is not very intuitive for beginners. Friends who don't know much about the equalizer here can also choose to use the "graphic equalizer" to adjust, and its operation interface is much more intuitive and easier than the "parametric equalizer". Here I use the "parameter 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 band or several frequency bands. The sound of "hissing" is usually around 8000Hz, and we will attenuate the sound intensity in this area (see Figure 3).

screen . width-500)this . style . width = screen . width-500； } " border = 0 & gt

This processing also helps to further eliminate human voices. For example, the frequency response of human voice is mainly intermediate frequency, so we can appropriately attenuate the intermediate frequency part. However, the sound of air and teeth is mainly above 6000 Hz- 18000 Hz, which can be attenuated according to the actual situation, but the clarity of accompaniment will be lost. Equalizers are generally used for repair and optimization, and the elimination of human voices depends on * "effect" → "waveform amplitude "→" channel remix ". Don't forget to save it when you're finished here!

3. Stereo effect enhancement

Stereo effect enhancement is a professional processing technology, because it can't be written completely at one time. Here I will briefly talk about the method of stereo enhancement. You can use stereo effect enhancement plug-ins (such as WAVES plug-in effect equipment is a good processing plug-in, which is not introduced here) or use professional stereo enhancement software to make appropriate adjustments, or you can add some reverberation effects appropriately.

4. Low frequency compensation

"Destiny takes a hand (accompaniment). mp3" is the result of eliminating the original music and hiss, but its audio is much attenuated. In order to compensate the low frequency, you can use the "equalizer" of Cool Edit Pro, but don't use this file that has been "cancelled" because its low frequency effect has been attenuated. If gain processing is carried out, the effect will not be as good as the original sound, so we use the original sound for processing. Take out the low frequency part of the original sound as compensation for accompaniment.

screen . width-500)this . style . width = screen . width-500； } " border = 0 & gt

Now, please listen to destiny takes a hand. MP3 "soundtrack, and select" Effect → Filter → Parameterized Epulizer "(Chinese means" Effect → Filter → Parametric Equalizer "). After entering the Parameter Equalizer, adjust the parameters, as shown in Figure 4. Click "OK" to process it immediately, so that you can get the low-frequency part of the soundtrack of Destiny. A file is temporarily saved here as "BASS).MP3". (Again, it's best to save it in lossless WAV format from the beginning, so the final effect will be better. )

5. Multi-orbit synthesis

I don't need to say more about multi-channel synthesis. I think you must be familiar with it. Here, firstly, insert the muted "Destiny takes a hand (accompaniment) .mp3" into the first track; "BASS .). MP3" is inserted into the second track, and the mixing and condensation are completed. If you feel that the volume of the two tracks is not very balanced, you can adjust the volume of the next two tracks under the multi-track here until you hear that the accompaniment is full and suitable for mixing and saving.

In fact, the key point of eliminating human voice is to strike a balance between the degree of eliminating human voice and the playback effect. If you don't consider the playback effect, the human voice can be eliminated more cleanly, but there is no need to do so, as long as the voice can cover the original song when you sing. Only in this way can we ensure the effect in the accompaniment band, and the original singing sound will not be too obvious.

I want to warn you here. I personally suggest that this method is only for reference and study, and don't expect it to bring you any good results. Also, the use of sub-methods mainly depends on the source of your muted songs. Not all songs can be eliminated. It must first meet the principle conditions I mentioned earlier. Don't blame yourself or others for not doing well, and don't blame your affectation or sound card. Because these methods have nothing to do with the equipment in production, the effect is by no means caused by your poor equipment. The function of sound card here is to output sound and let you get good or bad results. Finally, we still have to understand it carefully.
