If you want to be professional, it is recommended to use DART Karaoke Author
DART Karaoke Author (DKA for short) is a software specially designed for making karaoke accompaniment tapes, which is absolutely "stupid" in terms of interface and operation. Even friends who have no software experience and know nothing about acoustic principles can quickly get started and master its usage. DKA can not only directly silence the songs of CD tracks, but also operate files in WAV and MP3 formats. Its working platform is also very extensive, supporting WIN98, WIN ME, WIN NT and WIN2. In order to facilitate users to further process the songs, it also comes with a DART CD—RECORDER (DCR for short) audio track recording software, which can completely achieve a series of processes of collecting the original songs from the CD, then silencing them, then recording their own voices as needed, and finally recording them into AUDIO CD products, but it is very convenient! DKA's meticulous and considerate design has alleviated our operation troubles and made the most careful consideration for users!
(wizard interface)
After starting DKA, the first thing that appears is a wizard interface, where you will be prompted to complete the whole process of eliminating human voices step by step in order, which is very convenient for beginners! Of course, we can also turn off the wizard mode and set it ourselves. When we need it, we can also restart it with the RUN WIZARD under FILE. At first glance, DKA's interface is simple, generous and clear at a glance. Every toolbar command has an image icon, so you can understand it even if you don't know English! The largest blank area in the middle of the screen is used to display the waveform file of the song, and below it is the lyric display area, where you can input each lyric in turn (unfortunately, Chinese is not supported) and add it to the specific position of the song with the SET FLAG button while playing, so that you can switch to different positions of the song more quickly. On the right side of the screen is the selection of display scale, playback and playback synchronous display mode. There is no extra button in the whole interface, and friends who use it for the first time can really achieve the goal of mastering it quickly!
(vocalization setting window)
If you want to eliminate the original vocalization in a song, you must first import the WAV or MP3 file of this song with the OPEN SOUNDTRACK command in the shortcut toolbar. Of course, if you can't even find the software for capturing the CD track for a while, you can easily do it with the READ TRACK command in DCR! At this time, you will see the waveform file of the song displayed in the center of the screen. Select PLAY ALL on the right to preview the effect. Next, we set different mute settings for different areas according to the specific conditions of the original vocals, move the mouse to the progress bar above the waveform display, and press the left button to pull to form an area, which means that our processing only works for this area. At this time, press the icon of DEVOCALIZER to enter the setting window for eliminating vocals. You can see that the options here are very simple, and you don't need the professional knowledge of physical acoustics. You only need to adjust the ATTENUATION value of Attenuation, bass compensation value of BASS RETRIEVAL and OUTPUT volume, and listen to the processed results with PLAY RESULT until you are satisfied. It's as simple as that! Because DKA uses the principle of channel inversion for noise reduction, it is often necessary to set the attenuation value to the maximum to achieve satisfactory results, and then you will find that the sound quality is very thin compared with the original, and bass compensation is needed, so BASS RETRIEVAL should also be set to the maximum! After you are satisfied, determine the path of the OUTPUT FILE, and then press PROCESS, and you can hear the final result!
Of course, DKA's silencing effect for different songs is quite different. Some songs can't completely eliminate human voices, but they can reduce the proportion of human voices in music. At this time, if you superimpose your own songs, you can completely achieve the effect of accompanying music! According to the author's experience, many accompaniment bands with slight vocal original songs used in some karaoke halls are made directly with DKA, but some audio post-processing is added, and the effect is really good!
DKA is also powerful in that it provides a variety of other processing methods for accompaniment music after vocalization: you can burn the accompaniment tape after vocalization into CD audio track format; You can also record your own songs with DKA, and then synthesize new songs with accompaniment music; You can also use plug-in audio effectors to process the generated music files; You can even directly convert ready-made MIDI accompaniment music into WAV files. In short, a series of operations such as recording, processing, synthesizing and burning songs can be completed quickly with DKA software, which is very convenient!
(mixed window of accompaniment music and vocals)
Select KARAOKE PLAYER/RECORDER in DKA to set the recording, and after determining the output path of the recording file, press RUN to switch to the recording window. At this time, you will find that the lyrics you just entered are still displayed at the top of the screen during the recording process, which completely relieves your trouble of forgetting the lyrics! PLAY it with play after singing. How about it? Your voice is not bad! Finally, QUIT with quit and enter the next step-—KARAOKE PRODUCER. In the PRODUCER window, you can adjust the ratio of music to human voice. After that, press PROCESS to generate a new file, and a song you sang by yourself will be finished!
(MIDI to WAV setting)
the method of burning a CD is also very simple. Start DCR, put the WAV file just generated into the playlist, and just use WRITE TO AUDIO CD! Of course, you can also compress it into WMA format with ENCODE FILE. If you are not satisfied with the final result, use DIRECTX audio plug-in to do some more processing, and finally generate a new WAV file, depending on your requirements! One of the best tricks of DCR is that it can convert MIDI files into WAV format, and this function can play a great role! Stroll around the INTERNET and you will find many high-quality MIDI songs, which are the best accompaniment music materials. With DCR, everything is so simple. Just throw the MIDI file into the playlist, select the MIDI TO WAV button, then set the format and path of the output WAV file, and finally press the OK button. Isn't it convenient?
with DKA, you don't have to suffer from the trouble of finding a song accompaniment. You can proudly say that we do our own karaoke! Of course, DKA is not perfect, and different songs have different effects. But its powerful function and simple operation are enough to meet the needs of ordinary users. Now sing a song into the microphone, DKA, make you a singer dream!
If it's simpler, just use Kmplayer
Because Kmplayer provides commands to remove human voice and background sound under the menu of "Audio → Special Effects", you can also enable subwoofer, enhance treble, switch channels or remove left and right channels. Press Shift+F11 to slow down the playback speed, and press Shift+F12 to speed up the playback speed. And click the AB button on the far right of the play window to select some paragraphs or sentences to play repeatedly, and then click this button again to close the A→B loop, so if you want to practice karaoke with MM, this software is the best, hehe.
if you find that "Special Effects → Remove Vocal Voices" has no effect, please check whether "Audio → Ignore All Settings" is also selected, and if so, please remove this option.
if you think it is a little troublesome to remove vocals from the right-click menu layer by layer, you can press Alt+G to open the control box window and switch to the Audio panel, as shown in figure 4, where you can directly select the corresponding functions, such as removing channels, removing background sounds, removing vocals, and adjusting beats and tones, and all settings will take effect immediately.
