1. Validating a Chapter for ACX Submission
Independent Audiobook NarratorBackground
An independent narrator has finished recording and mastering the first chapter of a new novel and wants to ensure it won't be rejected by Audible's QA team.
Problem
The narrator needs to verify that the RMS level, peak amplitude, and noise floor comply with ACX technical specifications.
How to use
Upload the chapter file chapter_1.mp3 and select 'ACX (Audible/Amazon)' as the standard.
Standard: ACXOutcome
The tool reports a pass for RMS (-20.5 dB) and peak (-3.5 dBTP), but flags a warning that the noise floor is at -58 dB, recommending a slight noise reduction pass.
