How it works
- Add your files. MP3, WAV or M4A. Big chapters are fine.
- Choose. One or two choices. The rest is done for you.
- Download. One file, or the whole set at once as a zip.
There is nothing to install. It works in your web browser.
What it checks
The sound checks ACX asks every chapter to pass. Clean My Audiobook measures each one and fixes what it can.
ACX also listens to every file. It checks things no app can measure, like a chapter title read out at the start. So we say a file passes ACX's sound checks. Only ACX can say it will take your book.

Questions
Will ACX take my files?
Clean My Audiobook makes sure each file passes ACX's sound checks. ACX also listens to every file for things no app can measure, such as a missing chapter title. So only ACX can say yes.
Can I have music all the way through on ACX?
No. ACX hears music under the voice as noise. For ACX, choose music at the start and the end only. Music all the way through is fine for your own website and other shops.
Whose music is used?
Yours. You add your own music track, and it is kept for you next time.
How do I get access?
Clean My Audiobook comes with a licence key. Write to us and we will set you up. When you have your key, press I have a licence key and choose your password.
