Using Cool Edit Pro to eliminate the original singer can be said to be very simple, but it takes a little bit of work to make it perfect. The “single sing” is just a separate function in the Cool Edit Pro menu. When you select and use it, the result will be immediate. But to get the best results, just use Cool Edit Pro's "Destroy the sing" menu function is not enough! ! You have to do more detailed audio processing and setup. First, let us try the simplest method of eliminating the original singer. First enter the "single track editing mode" interface. Load an audio file with “File”→“Open”. I have already exemplified Cheng Qing's "Fighting Destiny" as an example. The file name is "Destined. MP3". After the transfer, select “Effects”→“Amplitude” →“Channel Mixer…..”(Chinese version is <quo;effect”→“waveform amplitude”→“channel weight Mix & rdquo;), in the "Presets" select "Vocal Cut" see (Figure 1), keep the default settings on the dialog box, click the "OK" button. After processing, I got the accompaniment music of the song "Fighting Destiny". The principle of the “Vocal Cut” function is to eliminate all sounds (including vocals and partial accompaniment) in the center of the sound image. Therefore, the main reason for using this function is to look at the source of the accompaniment. Whether there are instruments and vocals in the center of the sound field before mixing, if any, this function will eliminate it, resulting in the attenuation of sound quality. For example, the general sound field is placed in the center with "master voice", BASS & hellip; … and so on. If you need to silence the audio source is the source of these principles, I still recommend not to use this function, so the vocal did not disappear to eliminate the accompaniment music, it is really depressed, oh, let's listen to yourself. The result! Listen very carefully and you will find that the accompaniment is different from the sound of the original soundtrack. The original singing voice in the accompaniment band has become very "virtual", but the singer can still hear the original singing voice. In fact, this is the so-called anechoic effect (absolute drop to eliminate the original sing is impossible to drop). This kind of accompaniment effect can basically be taken as the background music of karaoke. When you sing, your cow-like screaming sound can cover the sound of the original singer. If it is not a friend who asks for the original accompaniment, this should be OK. Hehe. (I haven't finished it yet!) In addition, the audio quality in the entire accompaniment band has dropped. What we hear is a lack of stereoscopic accompaniment sound (similar to mono audio), and there may be some & ldquo The sound of 咝咝啦啦, rdquo;, the low frequency part has also been weakened a lot. In short, it sounds very unsufficient. Maybe 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 “rubbing principle” in front of me. 2. Cool Edit Pro eliminates the original sings. First, summarize the results we are not satisfied with. First, the sound of the original sing seems to be not clean enough; second, there is a murmur of “咝咝啦啦”; third, the stereo effect is reduced; fourth, the low frequency effect is weakened. The following four issues are corrected for the above four issues. First open in Cool Edit Pro “ hit destined. MP3 & rdquo; original soundtrack. 1. Eliminate the original vocals more cleanly Select “Effects”→“Amplitude” →“Channel Mixer…..”(Chinese version is <;effect”→“waveform amplitude”→ “Channel remixing""), "Vocal Cut" in “Preset”. Previously we were dealing with the 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” checkbox to compare the original sound. On the left, there are two “Invert” checkboxes. By default, one of them has “√”, now we cancel “√” cancel, the sound becomes more "dry&rdquo ;, but the sound field has to be wider, the stereoscopic effect is enhanced, but the low frequency is reduced more. Perhaps this effect is suitable for some songs, but it is not very good for some songs. It is still necessary to rely on everyone to slowly and carefully debug. If the method is not good for the song you are dealing with, it will remain the default. Settings.
this dialog box default settings in order to maximize the elimination of acoustic state, so in order to eliminate the acoustic cleaner is basically where there is no way. I personally found that the songs sung by different people are not the same. Some will be better, some will be less than ideal. However, we can optimize this process by using the four sliders on the left side of the “Channel Remix” dialog (Figure 2). Since the final effect is greatly affected by the original soundtrack, there is no fixed “fixed” setting. The stereo effect will be more obvious when the slider is slightly moved to the center point, but the vocals will become more obvious. . In stereo and vocal elimination, you have to compromise to one side. Here, the processed result is first saved as “ hit destined (accompaniment).MP3”. This treatment also helps to further eliminate vocals. For example, the frequency response of the general human voice is mainly based on the intermediate frequency, and we can appropriately attenuate the intermediate frequency part. The air sound and the tooth sound are mainly at 6000Hz — 18000Hz or above, and the attenuation processing can be performed according to the actual situation, but the clarity of the accompaniment will be lost. Equalizers are generally used for patching and optimization. The elimination of vocals relies on "effects"→“waveform amplitude”→“channel remixing” Don't forget to save it after processing it here!
