If you do not have a backing track for a particular song, you can turn almost any audio file with vocals into it. The implementation of such an operation may be required both for rehearsal before casting, and simply for performing a song with karaoke.
Instructions
Step 1
Try to find a file with the song you are interested in on the Internet in a place where it is posted legally. Many artists and bands post such files on their official websites.
Step 2
Make sure the music file is stereo. It is impossible to remove the voice component from a monophonic file by simple means.
Step 3
If you don’t have the file, write it down using any dedicated software program, from a CD, CD, or radio. The recording must also be in stereo. The law allows such recordings to be made for personal use.
Step 4
Install Audacity on your computer. It is cross-platform and runs on a variety of operating systems. If you are using Linux, first check if this program is already installed on your computer, and if it is not, try to find it on the disks with the distribution kit. In case the search was unsuccessful, download it from the following site:
Step 5
Open the selected or created sound file in this program.
Step 6
Click on the down arrow to the right of the track name and a menu will appear. In it, select the "Split Stereo Track" item. Two separate waveforms will appear for each channel.
Step 7
Select the bottom track, then choose Invert from the Effects menu.
Step 8
Turn each of the tracks into monophonic using the menu that appears when you click on the downward arrow located to the right of the track name. To do this, select the "Mono" item in this menu.
Step 9
Save the result to a separate file. Try to listen to it - you should get a backing track. Remember, however, that the voice will not completely disappear. But its volume against the background of music should be significantly reduced.
Step 10
Start rehearsing or using the file to sing karaoke. Do not distribute the resulting file.
