Sony Acid - Isolating Vocals from comlete music tracks

This is very very difficult to do. There are only a couple of ways I know how to obtain the vocals from any track. The easiest is to see if you can download the acapella version of the song from the web and I can tell where to look if you're interested. If you got to this page from my main page, it should've instructed you on how to download what you need. The other option that I know of is to use Software with vocal isolation algorithms and one that I've used before is quite a popular one, Sony Sound Forge. I don't use it much, only because it is a very complicated an technical program to use. It is used for mainly for sound editing, so if you're an audio engineer, you're probably fly at it. Even though you manage to isolate most of the vocals with it, you will not be able to eliminate all the music from the background. They are just not as noticeabe but low enough to be drowned out by your new Music Overlay. An easy way to mix vocals from a track with beats from another one is to simply Enable the mid and low frequency filters to reduce the mid and low sounds. Now you mainly have vocals and whatever is left - usually but not always.

Sony Acid - Coyping beats from songs

Its a very simple thing, to copy the beats from most your favorite songs. This is how you do it. You move your audio file from your file management window onto your ACID workspace and the software will render it's Graphical depiction of the song. All you need to do then is to find a short segment of the track where it lacks vocals, but you need atleast 1 full Measure or one complete loop of the background music. As you all may know, most background beats are just 8 or 16 beats relooped over and over again with some variations to form a track's background beats. Once you've found the segment, copy it and create a new line of audio file on the workspace just by right clicking and inserting a new audio file then paste it onto the new track. Copy it and repaste over and over for the desired duration. Listen to it and make sure that your relooping of the segment is one continious flow without any noticeable interruption. Once you've got that perfected, delete the original track from the workspace you copied the loop from leaving just your newly formed non vocal background music track. Render it as an mp3 file and there you go. you can now go and use it for whatever mixing you choose to.
