Full cast audiobooks are typically not fully scripted for audiobook production when they come to us, and as part of Pre-Production we help develop a production manuscript ready for recording. For example, many character attributions (e.g., “he said angrily”) can be omitted, as long as we have been introduced in the scene to the voice playing that character. We don’t need to say “angrily” since the actor will be acting that.
Some narrative may get converted to dialogue; some narrative may be modified to fit the dialogue around it. Other narrative may be replaced by sound effects, or altered to better accommodate those effects.
