The music obtained after eliminating the vocal part in the original music and audio files through noise cancellation software is called the silenced version of music.

The silenced version of music is generally used as accompaniment. Before the accompaniment of the original song was released, some singers and music lovers muted the original music in order to sing the song, and obtained a silenced version of the accompaniment, which was used as a temporary singing accompaniment.
