ChapterPass is a browser-based audiobook mastering tool created by audio engineer Giovanni Cordova to bring narrator recordings to ACX, Audible and Findaway technical standards, without manual audio engineering.
Who is Giovanni Cordova?
Giovanni Cordova is an audio engineer and AI builder with more than a decade in record production. He specialises in mixing and mastering, and has spent much of that time working in audiobook production.
The story behind ChapterPass
It started with a single project. A narrator had recorded her entire book but kept getting rejected on the technical review. She had the performance down. The files just needed corrections she did not know how to make.
Giovanni picked up the project and helped her get it across the line. Seeing her reaction when the files finally passed made something click: the corrections were the same every time. Loudness, peaks, noise floor. The barrier was never the person. It was the tools expecting her to learn audio engineering before she could publish her own work.
That is the problem ChapterPass was built to solve.
How ChapterPass works
- Provide your chapter file.
- ChapterPass masters it to ACX, Audible and Findaway technical standards, adjusting loudness, peaks and noise floor automatically.
- Download the mastered version, ready for publication.
There are no settings to configure or steps to learn. The process delivers a consistent, predictable result every time. Everything runs in your browser, so your audio files never leave your computer. This was a core design principle from the start.
Who is it for
ChapterPass is for anyone who needs audiobook files to meet ACX, Audible or Findaway technical standards:
- Narrators recording multiple books a year who want the mastering handled so they can focus on performance.
- Authors narrating their own work who have never touched audio software.
- Publishers managing chapters across several titles who need consistent results without sending each one to an engineer.
- Audio engineers who already know how to master by hand but want to skip the repetitive part.
- Anyone who has had a file rejected on technical grounds and just wants it fixed.
You focus on the recording. ChapterPass takes care of the rest.
