Editing Traditional animation (section)

===Voice recording===
Before animation begins, a preliminary [[soundtrack]] or [[scratch track (studio recording)|scratch track]] is recorded so that the animation may be more precisely [[synchronization|synchronize]]d to the soundtrack. Given the slow manner in which traditional animation is produced, it is almost always easier to synchronize animation to a preexisting soundtrack than it is to synchronize a soundtrack to pre-existing animation. A completed cartoon soundtrack will feature [[music]], [[sound effects]], and dialogue performed by [[voice actor]]s. The scratch track used during animation typically contains only the voices, any songs to which characters must sing-along, and temporary musical score tracks; the final score and sound effects are added during [[post-production]].

In the case of Japanese [[animation]] and most pre-1930 sound animated cartoons, the sound was ''post-synched''; the soundtrack was recorded after the film elements were finished by watching the film and performing the dialogue, music, and sound effects required. Some studios, most notably [[Fleischer Studios]], continued to post-synch their cartoons through most of the 1930s, which allowed for the presence of the "muttered ad-libs" present in many ''[[Popeye the Sailor]]'' and ''[[Betty Boop]]'' cartoons.<ref>{{cite book |last1=Sfetcu |first1=Nicolae |title=Animation & Cartoons |date=7 May 2014 |publisher=MultiMedia Publishing}}</ref>
