what is so far the best software which extracts the vocals from the instrumntals?

I want to get rid of the vocals from an mp3 file and its really hard to find a karaoke file of a not-so-famous song. so can you help me? ty.

Whether as a function of an application or a standalone app they all work the same way. Any audio information exactly in the center of the mix is removed.
How well it works depends on the way the track or tracks were mixed in the studio. Some tracks turn out better than others.
You can try it with Audacity.

Method:

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 in the center of the mix and could be removed or reduced also. A computer reads the vocal as data, likewise with bass and drums. Unlike our ears it can’t tell the difference.

To do this in Audacity 1.2.6:

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 1.3.7 beta.
Open the song in the program
Click, hold and drag to highlight the whole song or “Edit/Select/All” then select “vocal remover” from the effects menu.
Export and save from the file menu.
