ACX Painkiller app iconACX Painkiller for Narrators

Stop wrestling with ACX specs. Finish your audiobook faster.

ACX Painkiller turns chapter audio into ACX-ready MP3 deliverables in one local batch workflow, with built-in QC checks and clean output packaging.

Manually mastering chapters, checking loudness and noise floors one-by-one, fixing rejections, renaming files… every single book turns into hours of boring DAW busywork instead of narrating.

The Real Cost of ACX Spec Hell

  • •Hours wasted on repetitive QC instead of recording the next book
  • •ACX rejection emails that kill your momentum and delay royalties
  • •Inconsistent chapter files that make every upload nerve-wracking
  • •Cloud tools that force you to upload private audio and wait in queues

Sample report

“We've relied on this processing workflow for 15 audiobooks without a single ACX rejection on the technical side. It saved significant time and let our narrators focus on the content rather than tweaks.”
