"give a name to," originally "make a knight," from late Old English dubbian "knight by striking with a sword" (11c.), a late word, perhaps borrowed from Old French aduber "equip with arms, adorn" (11c.) of uncertain origin, but there are phonetic difficulties. Meaning "provided with a name" is from 1590s. Related: Dubbed; dubbing.
"add or alter sound on film," 1929, shortening of double; so called because it involves re-recording voices onto a soundtrack. The type of re-mixed reggae music was so called from 1974, probably for the same reason. Related: Dubbed; dubbing.

in filmmaking, the process of adding new dialogue or other sounds to the sound track of a motion picture that has already been shot. Dubbing is most familiar to audiences as a means of translating foreign-language films into the audience's language. When a foreign language is dubbed, the translation of the original dialogue is carefully matched to the lip movements of the actors in the film. Dubbed sound tracks rarely equal the artistic quality of original foreign-language sound tracks, however, and hence subtitles may be preferred by viewers as a means of understanding the dialogue in foreign films
