I need a program that I could use to remove vocals from a song so that I will only be left with the instrumental of the song. Is there a program that will allow me to do this?

If so, then what's the name of it and is there a possible way that I can download it for FREE?

Also, is there a way that I can do this process vice-versa? If I can remove the vocals from a song, then is there a way that I can remove the "instrumental" from the song and just be left with the vocals (acapella) version?

Unfortunately, there is no simple answer because it depends on many factors including what instruments and sound elements make up the non-vocal part of the audio signal and how these and the vocals have been processed and mixed into the final recording. In most cases, you can not expect to get results that are acceptable for professional use. However, in some cases, it is possible to render reasonable output useful in many, non-professional, scenarios. And, once in awhile, it is even possible to get excellent results.

You can find some software here which may help you:

While the automatic approach is easier, the manual approach can be accomplished in most audio editing software. It also provides insight into how the automatic vocal removal feature in most software works.

This method of removing vocals can be accomplished fairly easily, but depends greatly on how the entire mix was recorded. This method works when all or most of the non-vocal audio is mixed in stereo (some more to the left and some to the right) and the vocals are mixed in the center. Fortunately, this is common practice in popular music, making it a fairly reasonable method for many songs.

1. Open the stereo audio file in an audio editor.

2. Select and reverse the phase of the left channel (also called Invert or Flip). This option is usually presented in the Edit menu.

3. Mix the both the left and right channels of the stereo file into a single-channel (mono) audio file. This option is also usually found in the Edit menu, but is sometimes accomplished by editing the file's format properties from the File menu (ie. Sound Forge).

4. Split the single-channel audio file back into a stereo file that has the newly mixed single-channel on both the left and right channels. This procedure is usually close to the one used to mix the channels.

5. Now reverse the phase of the left channel back again, the same way it was accomplished earlier.

The resulting stereo audio file should now contain the same mix with all center-mixed audio cancelled from the mix. Hopefully, the entire instrumental contents will still exist, while the vocals will be canceled, or at least much more quite.

Thanks! I will give this a shot. I've been looking into getting Sound Forge anyway. It seems like a great audio editor.
