The "vocal cut" function is used to eliminate all sounds (including voice and partial accompaniment) in the center of the sound field ). Therefore, the main use of this function depends on the source of accompaniment. Whether there is an instrument and voice in the center of the sound field before mixing. If so, this function will eliminate it, this results in sound attenuation. For example, the general sound field is placed in the center with "Master voice", bass ...... And so on. If you need to use the audio source that is the source of these principles, I suggest you do not use this function. In this way, the voice is not lost and the accompaniment music is completely eliminated. This is really depressing.
Adobe Audition
Lead: Now many DVD players and software can eliminate the original singing of two-channel songs with songs, but you will find that after the elimination, the accompaniment will become a single-channel, and only play a small echo on the song. The latest version of Adobe audition solves this problem. It eliminates the possibility that the original singing not only maintains dual-channel sound, but also reduces the number of songs with a large echo and delivers better results, you can even convert the original VCD audio from the left-side accompaniment to the dual-channel accompaniment!
Netizens, in the wonderful time full of music, have indeed brought us a lot of joy. The beautiful songs have touched the hearts of each of us. The beautiful melody has opened our hearts, enrich our spare time. Yes! The music we listen to is sung by the stars. However, if you want to sing your favorite song, you need the accompaniment of the original song. In fact, you can also go to the audio and video store to purchase the artist's mtv vcd/DVD or kalaok VCD/DVD, or go online to find MP3 and Midi accompaniment, except for a few of the songs that can be found in the audio-visual store or online, some of them are single-channel accompaniment, but some have no accompaniment at all, what should I do if I cannot buy or find a accompaniment to my beloved song? It doesn't matter. This article can help you solve the problem! In addition, some have completed the accompaniment of the Guide music, some friends singing a very high level, do not need to guide the music, if you can not find the two-way accompaniment without the guide music, you can also use the original singing songs in the following introduction to eliminate the original singing and maintain dual-channel accompaniment. Of course, different accompaniment production methods have different effects, which should be determined based on your individual circumstances. In this article, we will introduce how to create two-way accompaniment for an existing single-channel accompaniment, remove a song from the original one, and create a two-way accompaniment for a personalized accompaniment.
The production software we use is Adobe audition 2.0. The work platform is applicable to Win98/ME/NT/2000/XP, this software can directly eliminate the original songs in the formats of Cd, Avi, mpg, MP2, m2t, WMV, ASF, mov, WAV, MP3, WMA, and Ogg, the software also comes with a sound track recording software, considering that the user needs to engrave the completed song accompaniment into a CD.
First, let's figure out what single and dual channels are. A single channel means that the sound of the left and right channels is the same. The music we listen to is in the middle. Note that some sound cards have sound loops. Please turn off the sound so that you can hear it; dual-channel means that the sound of the left and right channels is different, and the music we sound is scattered. In Adobe audition 2.0, how does one differentiate the Left and Right audio channels? The left channel is above the waveform, And the right channel is below 1.
For example, to listen to the left sound, move the mouse to the top of the left sound waveform, click the left button, then you will find that the right sound waveform is gray, you can only hear the left sound when playing the video. If it is the right sound, the method is the same, just move the mouse to the bottom of the right sound waveform.
Some may ask, "single-channel accompaniment is acceptable. Why do we need to create dual-channel accompaniment? Because dual-channel accompaniment has a three-dimensional effect, it sounds more professional. You can watch the singer's song Accompaniment in dual-channel mode and there is no single-channel. Some friends may ask, Midi accompaniment is also dual-channel, isn't it necessary to use the original song to create accompaniment? This depends on the individual's situation. After all, the sequence and effect of the Midi accompaniment are a little different from those of the original accompaniment. The sound card is not of high grade, the MIDI effect is only common.
Now, we can create our own kalaok! Some songs include single-channel accompaniment files, left-channel accompaniment, right-channel original-singing VCD files, and add the original-singing files of the songs. You can try the following methods to create accompaniment, the effects produced by the following methods are different, and the effects produced by different songs are different. For example, some songs are suitable for this method, and some songs are suitable for that method, it depends on the individual's situation and the Song situation.
1. Create an existing single-channel accompaniment into a dual-channel Accompaniment
Open Adobe audition 2.0 and click Edit, 2.
To open the audio file on the hard disk, click File in the menu, and click open in the drop-down menu to open the single-channel accompaniment file; to open the audio file on CD, click File in the menu, and then click extract audio from Cd in the drop-down menu) select the CD drive in the bar, and select the required single-channel accompaniment file (rare single-channel accompaniment files in CD, but still tell you how to open it, this will be useful in later sections). Click OK. If you want to open video files such as VCD, DVD, Avi, and mpg, convert the VCD video file To MPG first. The method is as follows: use Windows Media Player to open the DAT file in the VCD directory and try to find the one you need, when you open the DAT file in the VCD directory, select all files in the file type to display the DAT file. After opening the file, click the file on the menu, click Save as in the drop-down menu to save the media. change dat. MPG (Note: menu in my computer window In the folder option on the drop-down menu of the tool, you need to tick "Hide extensions of known file types" in the View window), save, you can also use professional software to convert dat to mpg, and also use professional software to convert DVD Audio To MPG (there are very few single-channel accompaniment files in the DVD). Here we will not discuss them one by one. Return to Adobe audition 2.0, click File in the menu, and click open audio from video (open the audio file in the video) in the drop-down menu. Then, you will find that the left audio is accompaniment, if the source song is on the right, What should I do if I only need accompaniment and do not need it? Don't worry, it's easy. Click effects on the menu, click ampler (amplitude) in the drop-down menu, and then click Channel Mixer (Channel Mixer ), in the Channel Mixer window, click the audio key in the lower left corner to listen to the music, and then select both = left or both = right in the effect preset column (if the accompaniment is the right audio ), click OK to convert to accompaniment.
Now let's start converting the operation into a dual-channel. Click effects in the menu, click delay effects in the drop-down menu, and then click delay ), in the delay window, click the pause key to listen to the music, and then adjust the delay time and mix until you are satisfied, you can also select the preset Latency Effect of the software in the effect preset column to change the single-channel to the dual-channel. Let's see if it has changed to the dual-channel! 3.
Click OK to convert the image into a dual-channel, click File in the menu, and then click Save As in the drop-down menu to save the file.
Finally, I will give you a reminder that this method is only for accompaniment. If you want to eliminate the original or guide music, do not use this method to convert to dual channels. Otherwise, it cannot be eliminated. Please find another way to obtain accompaniment.
2. Eliminate singing songs and create dual-channel Accompaniment
A song with a song must be a dual-channel to eliminate the original singing; if your existing dual-channel accompaniment has a guide music, you do not want to guide the music, you can also try this method to eliminate the Singing melody, which is equivalent to the lead singer.
Open a song with a song in the edit interface, click effects in the menu, click filters in the drop-down menu, and then click center channel Extractor (extract the middle channel ), select vocal remove in the effect preset column in the window of the center channel extractor, and click the audio key to listen to the music. Then you will find that it is accompaniment.
However, it has not been completed yet. Some songs have a small echo and can be changed. However, some songs have a large echo and will still hear a large echo, so we need to adjust it, adjust crossover (crossover), and put it to the left, side to test the effect, 4.
Careful friends, you will find that when crossover reaches 0, some songs still have a song sound. We can also operate the center channel level (center channel level), also to the left, at this time, you will find that there is almost no echo of the song, 5.
When a few songs arrive at this stage, if there are still some reasons for singing: first, because the lead singer is not completely symmetrical, the accompaniment is scattered in the left and right channels, but the lead singer is in the middle, the principle of eliminating singing is to remove the same sound (the middle part) on the left and right. The second reason is that the lead singer uses too many echo reverb effects. If the song is cleared and no sound is found, it means that the original song is a single channel.
In fact, there is no need to eliminate the lead singer so cleanly. It is irrelevant to have a slight song, because the more songs are eliminated, the more music instruments will be eliminated together, so we need to make different adjustments based on different songs, and you will also cover the slight song during singing.
Click OK to convert to accompaniment. After some songs are converted to accompaniment, the volume becomes smaller. Now we can increase the volume, click effects on the menu, and then click ampl, in the drop-down menu, click normalize (process), and set normalize to (standardized to) in the normalize window to a slightly higher percentage, which is generally 100%, and then click OK, 6.
If the volume is not satisfactory, you can undo the standardization you just made, redo it, undo the edit button on the menu, and click undo normalize (process) in the drop-down menu) (cancel the standardization process ).
If you feel a bit distorted during the playing process, that is, the volume is too high, and the color will be red in the upper and lower grids of the level line, we must cancel the redo standardization, until the upper and lower grids of the level line during Playing do not show red, 7.
After the accompaniment is completed, you can save the file.
In addition, we will introduce two methods to convert the original VCD audio from the left-side accompaniment to the dual-channel accompaniment.
First, if there is a music guide, it will also be eliminated. Of course, different songs have different effects, and some may have slight songs and music guides. Open the VCD audio file, open the center channel extractor window, select lift vocals 10db in the effect preset column, click the audio key to listen to the music, adjust crossover, and place it to the top left, adjust the center channel level and place it to the top right. You can also adjust the level based on different songs. Then, you will find that it is accompaniment, 8.
Second, if there is a music guide, it cannot be eliminated. Open the VCD audio file, open the Channel Mixer window, select Pan center left or pan center right in the effect preset column (if the song is left), click OK, then open the center channel extractor window, and create a accompaniment based on the previously introduced method of eliminating the original singing into a two-way accompaniment.
3. Create a personalized Accompaniment
Based on our individual needs, we can change the tone and speed of a song and make it a personalized accompaniment.
First, we will introduce how to change the tone of a song. Open the accompaniment of a song on the edit interface, click effects on the menu, and then click Time/pitch in the drop-down menu ), click pitch shifter. In the pitch shifter window, click the pause key to listen to the music, then adjust the semi-tones (half interval). The left direction is the bass, and the right direction is the high tone, you can choose high precision (High Precision) in the same way as precision, so that the sound quality is better, until you are satisfied with the click OK, and finally save the file, 9.
Next, we will introduce how to change the speed of a song, click the effects on the menu, and then click Time/pitch (Time/tone) in the drop-down menu, and then click stretch (process) (stretch Processing). In the stretch window, click Preview (PreView) to listen to the music, and then adjust stretch % (stretch %), Faster Tempo (acceleration), or slower tempo (slowdown), ratio (ratio), length (length), transpose (transformation), until the satisfaction of the click OK, and finally save the file, 10.
Well, after the personalized accompaniment is created, let's briefly introduce how to use Adobe audition 2.0 to cut the accompaniment into a CD, click the CD icon, and then click Insert on the menu ), after inserting the accompaniment file, you can move the order of the songs up and down on the right, remove the songs, set the parameters of the songs, and click write cd in the lower right corner... (CD ...), After setting the parameters, you can burn them! In this way, a personalized accompaniment album is released!
Of course, more friends want to add their singing songs to their personal albums. Here, I will also briefly introduce them. For detailed methods, see relevant articles. In terms of hardware, the performance of the computer is good, and the recording is not stuck. Choose a better microphone, and select the microphone input on the audio recording control; the software is still Adobe audition 2.0, you also need to insert some performance enhancement plug-ins, such as bbe sonic maximizer2.0.full, wave5.0, and TC. native. bundle. v3.1, ultrafunk3, etc., switch the interface to multitrack (multi-track), insert the accompaniment on the first track, and set the second track to the recording status. Note that the distance between the microphone and the mouth should not be too close during recording, it is best to avoid gas. After recording, we should first reduce noise, then use the Effect Enhancement plug-in to process human voice, and finally synthesize a complete song of our own. Are you very happy?
Now let's try out our results! Please listen carefully. You will find that the accompaniment is different from that of the original vocal cords. The original singing sound in the accompaniment band has become very "virtual", but the sound of the original singing can still be vaguely heard. In fact, this is the so-called effect after the silence (it is impossible to eliminate the original singing ). This accompaniment effect can basically be used as the background music of karaoke. When you sing, you can sound like a cow to hide the original singing sound. If you are not a friend who asks for an original accompaniment, you can leave it alone. (I haven't finished it yet !)
In addition, the audio quality in the whole playing band has declined. what we hear is a lack of three-dimensional accompaniment sound (similar to single-channel audio). There may also be some "Audio-seek" sounds, the low frequency is also much weaker. In short, it sounds really bad ".
Maybe you are not satisfied with this effect now, are you? Don't worry. Let's take a look at some advanced processing skills. Here, pay attention to the "anti-noise principle" I mentioned earlier.
Ii. Cool Edit Pro
Summarize the unsatisfactory results. First, the original singing sound seems to be not clean enough. Second, there are "audio and audio". Third, the stereo effect is reduced. Fourth, the low-frequency effect is weakened.
The following four problems are fixed one by one. First open the "destiny. MP3" source in Cool Edit Pro.
1. Eliminate the original singing sound to a cleaner level.
Select "effects"> "ampler"> "Channel Mixer ....." (The Chinese version is "effect"> "waveform amplitude"> "audio channel multiplexing"), and select "vocal cut" in "preset ". Previously we used the default value for processing. Now we try to adjust the parameters on the left side as shown in figure 2 ). During the adjustment process, you can click the "bypassa (pass through)" check box at any time to compare the original audio. There are two "Invert (reverse)" check boxes on the left. One of the check boxes is "√" by default. Now we cancel "√" and the sound becomes "dry ", however, the sound field needs to be more open and enhance the stereoscopic effect, but the low frequency is reduced more. Maybe this effect is suitable for some songs, but it is not very good for some songs. You have to debug it slowly and carefully, if the method is not good for the song you want to process, keep the default settings.
By default, this dialog box is in the State where the original sound is eliminated to the maximum extent. Therefore, there is basically no way to delete the original sound. I personally found that different people sing different songs with different effects. Some will be better, some will be less ideal. However, we can use the four slide on the left of the "audio channel multiplexing" dialog box to optimize the processing, as shown in figure 2 ). Because the final effect is greatly influenced by the original vocal cords, there is no fixed "fixed" adjustment here. You can only move the slider slightly to the center point, and the stereo effect will be obvious, however, voice will become more obvious. In terms of the effect of eliminating stereo sound and voice, we have to compromise with one party. Here we save the processed results as "destined for (accompaniment). MP3 ".
This processing also helps further eliminate voice. For example, if the frequency response of the Average Voice is dominated by the intermediate frequency, we can perform proper attenuation on the intermediate frequency part. However, the gas and tooth sounds are mostly between 6000Hz and Hz. The attenuation can also be performed based on the actual situation, but the definition of the accompaniment may be lost. The balancer is generally used for repair and optimization. The elimination of voice must rely on "effect", "waveform amplitude", and "audio channel multiplexing. After processing, do not forget to save the disk!
3. Enhanced stereo Effect
Stereo effect enhancement is a professional processing method. Because it cannot be completely written at the moment, here I will simply describe the method of stereo enhancement. You can use the stereo Effect Enhancement plug-in (for example: waves plug-in effect equipment is a good processing plug-in, I will not introduce it here) or use professional stereo enhancement software for proper adjustment, you can also add some reverb effects as appropriate.
4. Low Frequency Compensation
"Fate (accompaniment). MP3" is the result of our elimination of the original singing and the elimination of the "audio" sound, but its audio is much degraded. To compensate for the low frequency, you can use the Cool Edit Pro "balancer" here, but do not use this file that has been "eliminated" because its low frequency effect has been degraded, if the gain processing is performed, the effect will not be good, so we use the original vocal cords for processing. Remove the low-frequency portion of the vocal cords as compensation for accompaniment.
Now, we need to call "destiny. MP3 audio cords, select "effects" → "filters" → "parametric epualizer" (Chinese: "effect" → "filter" → "parameter balancer "), after entering the "parameter balancer", adjust the parameters to 4. Click "OK" and then process it immediately. In this way, you can get the low-frequency part of the "Destined" vocal cords. Here, a file is saved as "Destiny (bass). MP3 ". (Remind everyone that it is best to save the data in Lossless WAV format from the very beginning, so that the final result 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 we will first say "destined for accompaniment ). MP3 "is inserted into the first track;" It's a destiny (bass ). MP3 "is inserted to the second rail, and mixed condensation is done. If you think the volume of two audio tracks is not very balanced, you can adjust the volume of the next two audio tracks in the multi-track mode until you listen to the accompaniment very full, very suitable for mixing and saving.
The focus of voice elimination is to strike a balance between the degree of elimination of voice and the playback effect. If the playback effect is not taken into account, the voice can be cleared, but this is not necessary, as long as your voice can cover the original singing. In this way, the effect in the accompaniment band can be guaranteed, and the original singing sound will not be too obvious.
I personally recommend that you only use this method for reference and study. Do not expect any good results. In addition, the use of the secondary method mainly depends on the source of your silent songs. Not any songs can be eliminated. It must first meet the principles and conditions I mentioned earlier, do not blame yourself or others for poor performance, or blame your creation or sound card equipment. Because these methods are completely unrelated to the device, the effect is definitely not caused by poor equipment, here, the most effective sound card is used to output sound to give you good or bad results. In the end, you have to be careful with your experience.
Finally, I hope you can have a good time at Fufu (www.ifufu.com) and learn more, there can be great breakthroughs in hardware, software operations, recording, and effect production.

Silly:
Method 1: effect-stereo audio/video-audio multiplexing-select vocal cut
Create a left audio channel (left 100; right-100) create a right audio channel (left-100; right 100; reverse phase)
Method 2: effect-stereo audio/video-extraction center channel-Karaoke (preset effect)-male voice.
(After testing, this method works best in dummies)
Method 3: Edit-convert the sampling type,
In the displayed dialog box, select "Single Channel" in the "channel" option ".
Then, set the ratio of the left and right channels to 100% and-100% respectively.
The optimization formula is as follows:
Step 1 (same as method 2 ):Eliminate voice. Import the song to Adobe audition 3.0 audio track 1 in the multi-track view. Double-click the audio block to enter the editing mode. If the girl opposite the song has seen it, in the single track editing view mode, effect-stereo audio-video extraction center channel-Karaoke (preset effect)-male .com for the opposite picture (companion picture)
Here, we can also use the same silly method to eliminate human voices at the beginning of the frequency. Different singing methods have different effects.
Step 2: further eliminate noise
Effect-filtering and balancing-parameter balancer, adjust, confirm, and save.
Step 3: infrequent access
After the noise is eliminated, its audio is greatly reduced. Make up the low frequency.
Open the original audio file and import it to track 2. Go to the inter-Track 2 editing mode, and enable effect-filtering and balancing-parameter balancer. Perform the following adjustments:
Let's look at it for the opposite picture (bass?##### bass= ***************************************************
Step 4: multi-track Synthesis
Merge audio track 1 and audio track 2, select audio track 1 and 2, right-click audio track 3, and merge to new audio track-selected audio clip (stereo)
Save the synthesized audio as OK.
By the way, the WAV format provides better sound quality.
The latest version of audition is 3.0. The company that produced cooledit sold it to Adobe two years ago (the famous Photoshop is from Adobe). The famous audio editing software cooledit Pro 2.1 was renamed Adobe audition V1.0. Audition is much more professional than cooledit. In terms of operation and processing, it is better than cooledit. In addition, cooledit often has many vulnerabilities and such errors always occur, but audition won't. Of course, it is the first choice for recording songs and audio editing! Download is provided in many places, and I will not switch it If I search everywhere! If you are interested, try it ~~
This is the most convenient way to eliminate the original singing. If there is better, I will update it in time ~ I hope it will be useful ~
Silly:
1. Effect-stereo audio and video-audio-channel multiplexing-select vocal cut
Create a left audio channel (left 100; right-100) create a right audio channel (left-100; right 100; reverse phase)
2. effect-stereo audio-video-extract middle channel-Karaoke (preset effect)-male voice.
3. Edit-convert the sampling type,
In the displayed dialog box, select/in the/"channel/" option /".
Then, set the ratio of the left and right channels to 100% and-100% respectively.
Optimized:
Step 1: Eliminate voice. Import a song to Adobe audition 3.0 in the multi-track view. Double-click the audio block to enter the editing mode. For example, the song "Love" is displayed. In the single-track editing view mode, select "effect"-"Amplitude"-"Channel Mixer", and select "vocal cut" in the default parameter on the right.
Step 2: Repeat the edits to repair the sound of the instrument. Step 1: Listen to the concert and feel a bit distorted when the voice is eliminated. That is, the instrument is eliminated to varying degrees. Click multi-track view, insert the file to the second track again, and edit audio Block 2. Select "effect"-"filter"-"Graph balancer ".
Step 3: Adjust the gain range. In the "Graph balancer", the gain range is positive and negative 45 dB, and the 10-grid gain control in the middle is basically the frequency range of voice. The frequency band of voice coverage is reduced to a minimum, and one side is tuned and monitored until the voice is basically unavailable. To put it simply, it is to keep it close to 0 cells as much as possible.
Step 4: merge two audio tracks. After completing step 3, return to the multi-track mode, right-click the third audio track, and choose "Hybrid recording to track"-"All audio blocks. At this time, listening to the mixed audio is much better than completing step 1.
