Quick Summary — The 8 Steps
Finalize and Prepare Your Manuscript
Your manuscript becomes your recording script — and the two are not the same document. Written prose frequently doesn't translate to smooth spoken narration. Sentences that look clean on paper can feel clunky when read aloud. Before you record a single word, read every chapter out loud at home and mark the trouble spots.
Things to fix before your session: overly long compound sentences, parenthetical asides that interrupt the flow, visual content like tables or charts (which need audio descriptions), jargon or technical terms that need pronunciation guidance, and proper nouns with non-obvious pronunciations.
Pro Tip
Mark a pronunciation guide directly in your script for every word you're unsure about — place names, brand names, scientific terms, foreign words. Your engineer can't read your mind, but they can read your notes.
Decide Who Will Narrate
This is the most consequential creative decision in the process, and authors often rush it. Self-narration works exceptionally well for personal development, memoir, business books, and any content where the author's direct voice adds meaning and credibility. Your audience bought the book to hear from you — giving that narration to someone else can dilute the impact.
Professional voice talent makes sense for fiction, children's books, highly technical content with complex pronunciation demands, or situations where the author's voice genuinely isn't the right fit for the material. There is no universal right answer. If you're unsure, book a short test read before committing.
Pro Tip
If you're deciding between self-narration and a voice actor, book a 20–30 minute test session first. You'll know within 15 minutes how it feels.
Book a Professional Recording Studio
Home recording is the single most common audiobook mistake. It is also the most expensive mistake, because authors typically discover the problem only after ACX rejects their submission weeks later.
The problems with home recording are structural: untreated rooms create early reflections that leave a "bedroom sound" on the voice; HVAC systems create a noise floor that cannot be removed without destroying the voice; inconsistent microphone technique between sessions creates audible inconsistency. None of these problems are fixable in post-production after the fact.
A professional studio provides acoustic isolation, broadcast-grade microphones, a controlled signal chain, and an engineer who monitors quality in real time. For most authors, one studio session produces cleaner audio than months of DIY experimentation.
Pro Tip
Don't just look for a room — look for a studio with ACX-specific mastering experience. A room without an engineer who knows ACX specs helps you halfway and no further.
Prepare Your Voice
Your voice is the instrument. Pre-session vocal care is not optional if you want consistent quality across multiple sessions.
The week before recording: read your manuscript aloud for 20–30 minutes per day. This trains your voice for the stamina and pace of narration. The day before: avoid alcohol (dries the vocal cords), dairy (creates mucus), and excessive caffeine. Get 8 hours of sleep. The morning of: do 10 minutes of vocal warm-ups before you walk in. Lip trills, gentle humming, tongue twisters on the consonants that give you trouble.
During the session: room-temperature water only. Cold water constricts. Herbal tea with honey is acceptable. Hard candy between sessions can help lubricate, but avoid anything with sugar that causes mouth noise.
Pro Tip
Bring a printed copy of your manuscript — not just a tablet. Tablets require more eye movement and cause subtle pacing changes. A printed script with your markup stays put.
Record Chapter by Chapter
Most audiobooks are recorded chapter by chapter in a single isolation booth with the engineer in an adjacent control room, following along on their own copy of the manuscript.
When you stumble — and you will, everyone does — you don't stop the recording. You pause, take a breath, and re-read from the last natural phrase break. Your engineer marks the retake point. This keeps the session flowing without interruption and gives the editor clean splice points to work with.
Most narrators find their natural pace within the first 20–30 minutes. If you feel yourself rushing, slow down deliberately — speaking slower than feels natural in conversation is almost always the right instinct for audiobook narration. Listeners are following along, not in conversation with you.
Pro Tip
Don't try to be perfect on the first take of every line. Retakes are budgeted into your session time. Your engineer is not keeping score — they're building a finished product from whatever you give them.
Post-Production: Editing
After your final recording session, the editing process begins. This is where your engineer takes raw session audio — including all the retakes, stumbles, coughs, and awkward pauses — and builds a clean, continuous performance from the best material.
Editing involves: selecting the best take for each line or phrase, removing distracting breath sounds, cleaning up mouth noise (clicks, lip smacks, dry-mouth sounds), correcting timing and pacing, and assembling chapters into seamless reads that flow naturally.
Editing typically takes 2–3x the length of the raw recording time. A 5-hour recording session generates approximately 10–15 hours of editing work. This is why professional turnaround windows are 10–14 business days — it's not delay, it's thoroughness.
Pro Tip
Good editing is invisible. If you can hear the edits, the editing is bad. A properly edited chapter should sound like a single uninterrupted performance.
Mastering to ACX Standards
Mastering is the final technical step — and the one most authors know the least about. It brings every chapter to a consistent loudness level, eliminates clipping, ensures the noise floor meets ACX's requirement, and prepares files for distribution.
ACX requires: RMS loudness between -23 and -18 dB, peak levels no higher than -3 dB, noise floor below -60 dB, 44.1 kHz sample rate, and 192 kbps constant bit rate MP3 format. Every single chapter must meet every single spec. One chapter out of range means a rejected submission.
Professional mastering is what separates audiobooks that pass on first submission from the ones that spend weeks in technical review limbo.
Pro Tip
ACX spec: RMS -23 to -18 dB, peak -3 dB, noise floor -60 dB, 44.1 kHz, 192 kbps CBR MP3. Know these numbers or work with someone who does.
Quality Check and File Delivery
Before delivery, every chapter undergoes a final QC review — checking that specs are met, files are correctly named, room tone is present at the head and tail of each file, and the assembled audiobook flows correctly from chapter to chapter.
You receive organized chapter files, labeled per ACX's naming convention, ready to upload directly to your distribution platform. Most platforms — ACX, Findaway Voices, Spotify for Authors — walk you through the upload with a step-by-step interface.
Pro Tip
ACX has a specific file-naming requirement. Ask your studio to follow it before delivery — it saves a round of renaming at the worst possible moment.
6 Mistakes Authors Make When Recording Audiobooks
Most audiobook production problems are preventable. These are the most costly and most common.
✗ Recording at home in an untreated room
Room reflections and noise floor issues that cannot be fixed in post-production. ACX rejection is almost certain.
✗ Not reading the manuscript aloud before recording
Written prose sounds unnatural when spoken. Discovering this in the booth costs expensive studio time.
✗ Trying to record the whole book in one marathon session
Vocal fatigue in later sessions produces audibly different audio from earlier sessions, creating an inconsistent listening experience.
✗ Treating editing as optional
Raw recordings contain retakes, breath issues, mouth noise, and timing problems that are distracting to listeners and often fail ACX review.
✗ Skipping professional mastering
RMS levels, noise floor, and peak control require specific tools and knowledge. DIY mastering causes most ACX technical rejections.
✗ Submitting to ACX without checking specs
ACX's technical requirements are strict. Even one out-of-spec file in a 20-chapter book causes a rejection of the entire submission.
Self-Narrate or Hire a Voice Actor?
Use this to self-identify which path fits your book and situation.
You're a good fit for self-narrating in a studio if...
- ✓ Your book is nonfiction, business, memoir, or personal development
- ✓ Your audience would find your authentic voice valuable
- ✓ You don't mind some coaching and coaching through it
- ✓ You want to own the full creative connection to your content
You may want to consider a professional narrator if...
- → Your book is fiction with multiple distinct characters
- → You have a strong accent that doesn't match your audience's expectations
- → Technical content requires specialist pronunciation
- → You genuinely dislike the sound of your own voice and can't get past it

What Most Authors Underestimate
These are the most common production surprises — not to alarm you, just to help you plan better.
"I didn't realize how much How long editing takes matters."
Editing typically requires 2–3x the raw recording time. A 5-hour recording session produces roughly 10–15 hours of editing work. In a professional studio this is handled for you, but it's why turnaround is measured in weeks, not days.
"I didn't realize how much How different spoken prose feels vs written prose matters."
Sentences that look great on the page can feel clunky or unnatural when spoken aloud. Long clauses, em-dashes, and parenthetical asides are the most common offenders. A pre-session read-through at home reveals these quickly.
"I didn't realize how much How strict ACX technical requirements are matters."
Authors who self-record and submit to ACX often spend more time on re-recording and resubmissions than they would have spent recording professionally in the first place. The specs are strict, and platforms have automated rejection systems.
"I didn't realize how much How many retakes are completely normal matters."
Experienced narrators average 1–2 retakes per page. First-timers typically need more. This is completely normal, built into session time estimates, and cleaned up in editing. Aiming for "perfect on every take" is counterproductive.
