How do you remove some vocals on audacity?

Hi i want to remove some vocals on the audacity program, but i want to keep the beat %26amp; the chorus voice, just not the starting voice of the song. So the song should not be reduced in time, but just has specific voices removed. Does anybody know how to do it in audacity?How do you remove some vocals on audacity?
The method used to remove vocals removes any content as data in the center of a mix..

The lead vocal is usually central so is removed or at least (hopefully) reduced.

Drums and bass are also usually central in the mix and can be removed or reduced also.

It is not possible to select what you want to remove once the original multi-track studio recording has been mixed down to a stereo track.



All vocal removers use the same method so Audacity will not do any better than any other app.



Here's the method using Audacity:



This is possible only for certain stereo tracks. When the vocals are exactly the same on both stereo channels, you can remove them by “subtracting” one channel from the other. This works for many studio recordings, where the vocal track is mixed exactly in the center. Be aware that bass and drums are usually panned to the center and can be removed or reduced also. Depending on how the track was mixed the vocal may only be reduced, not fully removed.



To do this in Audacity 1.2:



1. Import your stereo file into Audacity.

2. Open the track menu (click the arrow next to the track title), and choose “Split Stereo Track.”

3. Select the lower track (the right channel) by clicking it in the area around the mute/solo buttons.

4. Choose “Invert” from the Effects menu.

5. Using the track menus, change each track to “Mono.”



Press the Play button to hear the results. If you are lucky, the voice will be gone but most of the other instruments will be unaffected, just like a karaoke track. You can use the Export commands in the File menu to save the results.



Audacity 1.3.12:

Has a vocal remover built in. Just select the whole track then vocal remover from the effect menu.
