The following text will introduce 5 vocal removers (even free vocal isolation software) that can help you get rid of lyrics or singings from a song completely. But you don't have to be that professional if only you make use of some good audio editing software applications. Things will be much easier if you know the knowledge about common ranges of audio frequency or say, spectrum, especially in music.

But the truth is each sound has a signal wave.

Yet unlike our own ears that can distinguish different sounds easily, tools cannot hear and would not be that smart. Unlike a video, audios and music cannot be seen (although technically you can, if you use a music visualizer). There are times when you need to remove vocals from a song for example, when you cannot find a suitable original accompany but want to make a Karaoke version of a song when you need to split one or more audio tracks/parts for re-mix, mashup or further editing when you want to isolate some instruments like bass, drums and piano to create minus one or a cappella.
