Audible's ACX has eight technical checkpoints, and a file that misses one comes straight back. chapterpass takes the guesswork out of that loop.
Drop your chapter files in and chapterpass masters each one to spec: RMS loudness between -23 and -18 dBFS, peaks held below -3 dBFS, a noise floor under -60 dBFS RMS, room tone at the head and tail, and a 192 kbps CBR MP3 on the way out. Every output is verified against the full spec before you download it, and you see the measured value next to the requirement for each checkpoint, so you know exactly what changed and why.
The processing runs in your browser through WebAssembly. Your audio never leaves your device, never touches a server, and never sits in someone else's queue. That removes the rights and privacy questions that come with uploading an unpublished manuscript to a cloud service, and it means results arrive in minutes rather than days.
There is no account to create. Your first file is free. After that it is $36 per finished hour, $27 from 5 hours, $18 from 10 hours, billed by the second, with the price shown before you pay. A typical ten-hour title costs $180.
If you only want the numbers, the free measurement page at /free-acx-check reads your loudness, peak, noise floor and silence padding against the spec without mastering anything.
chapterpass masters the measurable technical specs. It does not edit your recording, remove noise, or fix narration. Built by Giovanni Cordova.
