Using energy from sound effects in animation

The energy produced by the synchronous sound effects in animation is used as a source of kinetic energy. In most of the cartoon films the sound tracks are mainly constructed from pings or kerthuds etc for energizing a scene. This is a good example of kinetic energy usage. Sometimes such sounds are recorded beforehand and then logged on to the scene like a voice track. This is called a pre-synchronous process.

While there are various types of animation sounds, we will discuss here mainly the three such types.—pre, post and non-synchronous sounds.

  • Pre-synchronous sounds

The pre-synch creation of sound is done when music and sound effects in animation is required before the images are produced. Thus, the animation produced is said to be “shot to the track”.

Whenever the requirement of a precise synchronization between the picture and sound is there, the pre-synch process gives the best results. While the voices are recorded in a pre-synch mode, the result is a highly entertaining animation for the audience. The most difficult phase in the animation film is for the animator to decide on pacing the events and action. It is difficult to determine the extent of every incremental movement. Pre-synchronization helps for solving such difficult problems while shooting. In this process as the voice is recorded, filtered and finally logged, then the voice log determines pace events, as same have to follow in relation to these logs only. Therefore, all dramatic and surprising sound effects in animation are recorded before the actual shooting. Every instrument counts are logged to accompany a particular movement in the visual animated event, thus matching the movement of a particular pace or action with the sound of a particular instrument.

  • Post synchronous sounds

Here it is the reverse of the above as the images are shot before the sound effects are recorded. The visuals are the determinants for the sound tracks and effects, as they are done to finish the outer orientation of the animation film, established by the visual shots. In this case, the primary source being the visuals that determine the pacing of events, sound tracks can be added during post-production phase as well. Actions like a door closing or a gunshot or a telephone ring can be recorded in this manner, as they will require a particular sound effect to be added to that action frame.

SOUND EFFECTS IN ANIMATION should match visuals

For all those who are starters in the animation film shooting, the picture is the first thing that they will like to shoot. Once the visual jobs are completed and the picture is finished, the sound effects, music elements etc are then added.
