How to Edit an Audiobook: A Step-by-Step Workflow

Editing is where a raw narration becomes a smooth, professional audiobook. It is also the most time-consuming part of production: expect 2 to 4 hours of editing for every finished hour of audio. This guide walks through the same workflow professional audiobook editors use, so you can edit your own book or know what to expect from an editor.

What you need

• A DAW (digital audio workstation): Audacity (free), Reaper, Adobe Audition or Pro Tools.
• Closed-back headphones and, ideally, a pair of speakers for a second check.
• Your final manuscript, open next to the audio.
• Optional repair tools such as iZotope RX for clicks and noise.

Step 1: Organize and back up your files

Keep a copy of every raw recording untouched. Work on copies, one project or track per chapter, named in reading order. Save your 30 seconds of room tone from each session — you will need it to fill gaps.

Step 2: Do a first clean-up pass

Apply only light, consistent processing before editing: a high-pass filter around 70–80 Hz to remove rumble, and gentle noise reduction if the room is noisy. Heavy noise reduction early makes edits harder and voices sound thin.

Step 3: Remove mistakes and retakes

Listen with the manuscript open. When the narrator stops and re-reads, keep the best take and cut the rest. Cut on a breath or in a natural pause, and add a very short crossfade (5–10 ms) so every edit is silent. If you recorded with punch-and-roll, most of this is already done.

Step 4: Clean mouth noise, breaths and plosives

• Clicks and lip smacks: remove with a de-click tool or by careful manual edits.
• Breaths: lower loud breaths rather than deleting them all — total silence between sentences sounds robotic.
• Plosives (p, b pops): reduce with a high-pass on the pop only, or a dedicated de-plosive tool.
• Background bumps: chair creaks, page turns and stomach noises get cut or replaced with room tone.

Step 5: Set natural pacing

Consistent pauses make an audiobook easy to follow. A common starting point:

Where	Typical pause
Between sentences	0.5 – 0.8 seconds
Between paragraphs	1 – 1.5 seconds
Scene breaks	2 – 3 seconds
After chapter title	1.5 – 2 seconds

Fill shortened gaps with room tone, never digital silence — silence drops the noise floor to zero and sounds like a dropout.

Step 6: Even out levels between sessions

Narrators sound different on different days. Match the tone and loudness of every chapter so a listener never notices where one session ended and the next began. Gentle EQ and compression are usually enough.

Step 7: Proof against the script

After editing, listen to the whole book again with the manuscript — ideally a different person does this. Log skipped words, misreads and leftover noises with timestamps, record pickups, and drop them in. Read more about audiobook proofing.

Step 8: Master and export

Finally, master each chapter to ACX specs: RMS between −23 and −18 dB, peaks below −3 dB, noise floor below −60 dB, room tone at the head and tail, and MP3 export at 192 kbps CBR. Our ACX requirements guide covers every spec.

Common audiobook editing mistakes

• Over-processing with noise reduction until the voice sounds underwater.
• Removing every breath, which makes narration sound unnatural.
• Using digital silence instead of room tone.
• Inconsistent pause lengths between chapters.
• Skipping the proof listen.

Editing a full book yourself takes time and practice. If you would rather spend that time writing or recording, our audiobook editing service handles it from raw files to ACX-ready masters.
