Audacity is an open-source audio recording and editing package that is used to record both music and voice, as well as to edit recordings of songs in mp3 and other commonly used digital audio formats. Since Audacity has features that enable you to split the voice and music tracks of a stereo audio file, you can use the program to save only the vocals from a stereo recording of a song. You simply use the program to separate the stereo track into two mono tracks and you save only the track that contains the vocals.
Launch Audacity and use the "Open" command in the "File" menu to import the file you wish to edit into Audacity.
