Note 8: The technique of versioning or "dubbing" e.g. a cartoon, is nowadays in itself an advanced and complicated process, which, however, especially thanks to electromagnetic audio tapes makes it possible to record or record dialogue, song, sound effects and music separately. Yes, in fact, one often also records the voices of the participating actors or singers separately, which are then later mixed together on a so-called master band. The recording or recording takes place in a sound studio, where the actor or actors 'voices' via headphones hear the original sound of each scene separately, while watching the film scene in question, either on a screen or a monitor (TV screen). After several rehearsals and when the 'voice' appears ready for recording, the sound engineer initially mutes the sound, after which the actor in question concentrates on getting the spoken words to best fit the figure on the screen or screen. When recording a song, the actor continues to hear the music from the audio tape via the headphone.
