Question for Audacity Users

Post by James Sission »

I was looking over the forum and FAQ's on this site. It looks like a really cool program. I was wondering, if you have a commercial CD and you load it to your computer, then convert it to a wave file, can you split the tracks at that time and delete something off it, like a vocal or a lead instrument?....It seems like from what they are saying, that can be done, but since I have not actually downloaded to software to try it, I am not sure. I cant download anything on this computer to try it, but I will when I can get back home...Any users tried this ?.....James

James, this is what Goldwave, which is an excellent audio editor, says about "reduce vocals" - a function that Goldwave has. It probably applies to most programs that remove vocals (except the high $$ commerical studio programs).

There's nothing that I know of except possibly some expensive commercial software that will remove an instrument from a mixed down song.

Use this effect to reduce vocals in music. In some stereo recordings it is possible to remove vocals by subtracting the left and right channels. In order for this to work perfectly, vocals must be identical (recorded equally) on both the left and right channels. If there is any stereo echo or reverb applied to the recording, vocals cannot be removed completely.

Note that any instruments recorded equally on both channels will be removed along with the vocals. This is unavoidable.

Usually subtracting the left and right channels destroys the stereo sound, giving mono output. However, by integrating a bandstop filter, GoldWave is able to restore some of the stereo, enhancing the output. Try the Reduced vocals with more stereo preset. Bring the From and To filter values closer together for increased stereo (increases the vocals) or farther apart for reduced stereo (decreases the vocals).
