[TUT] How to remove music/sfx and keep the voices.

[CodeBrain]

Hey guys, ever wanted to get a vocal from a file, but have all that music and sound effects blocking the voice itself? Don't feel like modding a game just to get that voice? Here is a tutorial on how to remove music/sound effects, while keeping the voice intact.

Programs used:

Music Morpher Gold (http://www.musicmorpher.com/free-music-editor.htm)
Audacity (http://audacity.sourceforge.net/)

Part 1:




Step 1: Open a song
Click on Morpher tab on the module bar to open AV Morpher.
To open a file, click File on the menu bar and choose Open (1). Open dialog box will come up, select an audio file you want to open. You can also use Open from library, Add Files to Playlist, Add Folder to Playlist button (2) on the toolbar to add a file to the playlist.

Step 2: Extract the voice
Press Active button under the playlist box. Open the list on the right of the button and choose Voice Extractor.

There are 3 main parts you have to concern.

Center Width (1): This is the width of the range of voice that will be analyzed. This parameter were made up from analyzing the difference between right and left channel. The more you move this slider to the right, the more sound is extracted. So move it slowly until you're satisfied with the result.

Note: This is the most powerful parameter which will strongly affect on how much sound and voice is extracted from the song.

Center filtering (2) will have 2 sliders: High Pass Filter and Low Pass Filter. The High Pass filter will decide how much vocal is extracted. The more you move this slider to the right, the less voice is extracted. That means the more sound is removed. This parameter attacks most of the sound of a song. Sometimes, you can get the voice perfectly by increasing this slider but sometimes, most of the sound including the vocal is removed. So we recommend you move it slowly.

The Low Pass Filter has the opposite working way but its main benefit is reducing the noise. Usually after you adjust these parameter, the remaining of the music (which isn't processed) causes the noise to the song. So move this slider to the right to remove more noise and to the left to keep more sound.

Vocal Pitch (3): This is the last key of voice extractor. The more accurate adjustment you make, the better sound you will get. By moving this slider, you will point out fundamental frequency of speech signal of singer's voice. After that, Music Morpher Gold will build up the library of formant frequency of that voice and keep the sound on these frequencies. The sound of other frequencies is not the vocal and will be removed. So please listen the music carefully while you move the slider and stop when you hear most of the voice is extracted.

After that, move the Notch Width to the right to extract more sound or vice versa. 7 may be the best.

Note: The vocal pitch of male singer is around 250Hz and vocal pitch of female singer is around 720Hz. You can use the left or right button on the keyboard to move the slider more accurately.

Step 3: Morph the song
Press Morph Selected Files button on the Playlist toolbar.
The Morphing dialog appears. Select an Output Folder and MP3 File Format, then click Morph button to start the morphing process.

Note: The quality of removed or extracted files depends on how songs are recorded and mixed. Sometimes vocals are placed in a stereo field in such a way that prevents removal. If songs are recorded in this way, their vocals cannot be removed at all. This is why some vocals can be removed and some cannot. Therefore, users should not expect this software to remove vocals 100% of the time. In most cases, however, it will successfully remove vocals. Sometimes it might sound as if the vocal has not been completely removed; however when the user inserts their own voice, or if the file is then used as a karaoke tune, they will only hear the new voice along with the original music.

Part 2:




Step 1: Open Audacity.

Step 5: Click on Get Noise Profile, and go back to it again (Refer to step 4 of Part 2)

Step 6: Play around with it, it's your opinion on how you want the sound to, well, "sound" like :3

Step 7: Click Remove Noise, save and your done!


And that's it.

I installed AV Morpher, when I opened it, it said my trial had already run out??

Do you know how to do the opposite? Like take the lyrics out and just have the beat? There was a method using Audacity but it made the vocals just have a decreased volume.

Pretty cool, but how about getting audio when there's music in the background?

Silly Limited, you needed a serial for it, get a free one: http://www.musicmorpher.com/free-tutorials/MMG-get-free-key-vid.htm

I believe that was the only way, I haven't tried to do that though, sorry.

My sound I used (called test.mp3 in the pics) was Cortana saying "It took two in the nose and dropped into the atmosphere" while the Mombasa_Suite mp3 was playing, ALONG with the Pelican's engines. This sound file was from the H2 e3 2003 beta.

The result? Her voice only, no pelican engines OR music. :D

Limited, you're going for a voice canceled audio file, I don't believe it's completely possible to have the voice removed.

Think of it in terms of photoshop and the studio (Though I'm not exactly sure how the studio works) You have layers available to you on PS. I guess you can say those layers are similar to each different voice and instrument you hear that are all recorded separately, but at the same time. In PS, when you're done, you usually merge layers, or flatten or whatever and it's almost impossible to retrieve an original object that already mashed in with other effects(except when you do ctrl-z, but you can't do that in life =P). Just imagine that with recording studios (that's how I thought of it).

Program crashes when I open it. Says there's an error exectuing the DXEffectTester.exe file and it has to close. Redownloading, reinstalling and restarting my computer have done nothing. Oh well... :(

E: Nvm, fixed it by downloading the .rar instead of the .exe :P

E2: Couldn't get vocal remover to work very well on the audio files I had, so I started screwing around with the effect filters. The Drunk one is pretty funny.
