Dear Wayne

Is it possible to edit solo or duet song without Music generated by Musical Instruments but will have only Human Voice ?.

Example :

Bee Gees, Staying alive Song.

Youtube Video

Example :

Bee Gees Brothers are singing this song. In the background, music
is being played which was generated by musical instruments viz guitar,drum beats etc. The Music played by musical instruments are in sync with the Bee Gees voice. The complete song is recorded on magnetic, Optical media viz CD, DVD, Tapes etc

Is it possible using sound editing software to edit the song without any music generated by musical instrument but the song will
be only with Human beings voice i.e. Bee Gees Brothers ?.

i.e. It should be like Bee Gees Brothers are singing this song but without any musical instruments.

Awaiting your reply,

Thanks & Regards,

Answer
While I've seen and used programs to remove vocals from recordings, I have never seen any programs that removes music but leaves vocals.

You may be able to if you have a Dolby Pro Logic receiver... on most stereo tracks, vocals are panned to the center, and a Pro Logic receiver would send that audio information the a center channel speaker / output. It may have some music "leakage" into it, but for the most part, it should strip the music from vocal tracks.

I hope this helps you a bit... good luck
