Voice recording and Soundtracks-
The musical score (background music) and sound effects are usually put in the production after the cartoon and voiceovers are complete.
The final cartoon soundtrack is created after animation is done. It goes way beyond just dialogue. It will have several different tracks. One track will feature music, another will have sound effects, and another will have the voice dialogue. the final musical score and most sound effects are added after the other work is done.
In some cartoons, the final voices and sound effects are post-synched or recorded after the film parts are finished. This is accomplished by watching the actual film and performing the dialogue and sound effects.
This is similar to dubbing a different language into a tv show or movie. The original tracks for music and sound effects stay in place and the original voices are redubbed in a new language with different people doing the voices.
Synching sound to action
The x-sheet is a printed guide that gives the animator a frame by frame list of the action and sound.
A synched animation is drawn based on the timing of the voice soundtrack. In order to help the animator to match the prerecorded voice track an exposure sheet (aka X-sheet) is required.
A bar sheet is also used with the X-sheetBar sheet to give a guide for on-screen action, dialogue, and the musical notes in the musical track.
