How do I create a instrumental of the song using those two and audacity?How to create a instrumental using the acapella and original using Audacity.?
The only way to create an instrumental is to remove the vocal from the original..

Unfortunately once the track has been mixed down to stereo in the studio the vocal removal method is very hit and miss.

The only way to fully remove a vocal track is with the original multi-track studio recording.

The Audacity method is set out below.

As the success or not of the removal depends on how the track was mixed in the studio and as all vocal removal programs use the same method there is little you can do if not successful other than try a search for an instrumental version.



Vocal removal 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 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.
