# Footnote 4: Producing an Audiobook

A practical look at Eddie's audiobook production pipeline, including recording, cleanup, mastering, ACX standards, chapter exports, and final proof-listening.




## Page Content

I have published a new segment to the [NosillaCast podcast](https://www.podfeet.com/blog/category/nosillacast/), hosted by Allison Sheridan over at [podfeet.com](https://podfeet.com/).

Producing a genuinely professional audiobook is less “hit record” and more a small-scale engineering project: you’re managing hours of narration, a pile of WAVs, and a set of unforgiving standards (I use Amazon’s ACX specs as the baseline because everyone else seems to fit inside them). In this segment I walk through my end-to-end pipeline as narrator, editor, producer and publisher—how I record and archive a pristine original, do a first “cleaning” pass in iZotope RX to tame breaths, fluffs and mouth noise without changing file lengths, then a separate enhancement pass (de-click, de-noise, de-ess, loudness control) before moving into Logic Pro for structural work like trimming silences, chapter handling, and adding consistent room tone so nothing drops to dead silence. I also cover the final polish stage—EQ, loudness mastering, and the slightly tedious export/bounce routine—plus the last, non-negotiable step: listening to the whole finished book again before uploading, because a single missed line or skipped scene can undo weeks of work.

Happy reading,

—Eddie.
