What does overdubbing mean?
Overdubbing is the process of recording additional audio over an existing performance. A musician, voice actor, or dialogue artist may use it to replace an incorrect note or phrase, add another vocal line, or build a more complex arrangement. The technique is especially important in multitrack recording, where individual parts are captured separately and combined later. Overdubbing is not quite the same as mixing: mixing combines recorded tracks into a final balance, while overdubbing is the act of making the new recording itself. Although often associated with professional studios, it is also used in home recording, animation, podcasts, and video production. The word is especially useful when describing a recording process that adds refinement or complexity to an already completed take.

"The singer returned to the studio for some final overdubbing before the track was released."
"The producer asked for more overdubbing on the chorus to strengthen the harmony."
"Because the original dialogue was unclear, the scene required several hours of careful overdubbing."
Overdubbing lets performers build a finished recording one layer at a time, correcting mistakes without starting the whole track again.

Where does overdubbing come from?
Overdubbing combines the prefix over- with dubbing, a word associated with adding sound to an existing recording. Dub itself developed in the context of sound recording and performance, while the compound form emphasizes the layering of a new recorded passage over an earlier track. The terminology reflects the practical shift in recording technology from capturing an entire performance at once to assembling and revising it in separate layers.
