Making an A Capella

• 1). Open your audio editing software and load the original MP3 and instrumental tracks one below the other. The order is unimportant.
  
  
• 2). Line up the two tracks as closely as possible, using the visual peaks as guidelines. Playing both tracks at once can help you align them properly.
  
  
• 3). Select the instrumental track (depending on your program, this could mean simply clicking a button next to it or highlighting it) and look in the effects menu for the "Invert" option. Invert the instrumental track, then go back to display both tracks; notice how the peaks and valleys of the instrumental track are now directly opposite the corresponding peaks and valleys of the original MP3.
  
  
• 4). Zoom in as close as possible on either track to fine-tune the alignments. Make sure the files are exactly aligned; again, playing both tracks will help you determine if you need to make alterations and let you hear when the music has been canceled out to leave the a capella as clear as possible.
  
  
• 5). Save your file when you're satisfied with the a capella. In most programs, you can do this by selecting "File" and "Save As..." The resulting MP3 will be vocals only, leaving you with a custom a capella to use with your project.
