Sound Familiar?
These are the problems narrators and publishers send us every day.
Audible rejected your files for noise floor or RMS out of spec
Chapters recorded weeks apart don't match
Your retakes sound different from the take around them
The narration is great but the room tone drifts through the book
You have no idea what -23 to -18 dB RMS actually means
You're spending as long editing as you spent narrating
We fix all of these — and get you through Audible QA the first time.
What We Do for Your Audiobook
Every step between a good narration and an accepted, retail-ready audiobook.
Mastering to ACX / Audible Spec
RMS between -23 and -18 dB, peaks under -3 dB, noise floor below -60 dB. We hit the spec so Audible accepts it first time.
Noise Floor & Room Tone
Remove hiss, hum and drift, and lay in matched room tone so every chapter sounds like the same room on the same day.
Chapter-to-Chapter Consistency
Level, tone and presence matched across sessions recorded days or weeks apart — no jarring jumps between chapters.
Retake & Punch-In Matching
Blend pickups and retakes into the original take invisibly — no obvious edit seams, no tonal mismatch.
Chapter QC & Metadata
Correct file lengths, opening/closing credits, retail sample, and per-file metadata to Audible's structure.
Proof-Listening & Error Report
A full listen-through flagging misreads, clicks, breaths and drop-outs — the report ACX rejections come from.
Priced Per Finished Hour
The industry standard — you pay for the finished runtime of the book, not studio hours. Publishers and prolific narrators: ask about catalog rates.
