Overdubbing (Layered Recordings) Layering recording over an existing audio file is called "overdubbing." Using the Overdubbing function enables you to add a recording [B] of a chorus and/or a guitar solo to an existing audio file [A] that contains only vocal and rhythm guitar performances to create a combined audio file [A+B].
