Wild track, also known as wild sound and wild lines,[citation needed] is an audio recording intended to be synchronized with film or video but recorded separately. Generally, the term "wild track" refers to sound recorded on the set or location of a film, such as dialogue, sound effects, or ambient or environmental noise gathered without cameras rolling.[1][2] Wild tracks of dialogue are often recorded if dialogue could not be properly obtained during filming due to the presence of devices that produce noise, such as wind machines.[1]
