What audiobook editing involves
Editing is the longest stage of post-production. A professional audiobook editing service typically spends several hours on each finished hour of audio.
Removing retakes and errors
Narrators repeat lines after a stumble. The editor keeps the best take and removes the rest so the listener hears one continuous performance.
Noise cleanup
Mouth clicks, loud breaths, page turns, chair creaks and outside sounds are reduced or removed by hand. Heavy automatic processing is avoided because it damages the voice.
Pacing
Pauses between sentences, paragraphs and sections are adjusted to a consistent rhythm, and room tone fills every gap so silence never sounds empty.
