ChapterSplit

Choose Auto, Embedded Chapters, or Silence Detection. ChapterSplit can read chapter markers from metadata or detect natural breakpoints by analyzing silence patterns.

During silence detection, the app reports analysis progress (time elapsed, estimated remaining, and scan speed) so you always know what it’s doing.

Keeps cover art (when available) and writes sensible metadata for each exported chapter, including optional track numbers.

Generate consistent filenames with 2‑ or 3‑digit numbering, optional chapter prefixes, and the option to continue numbering across multiple input files.

Optional ‘safer’ encoding settings for maximum compatibility, including fixed sample rate and bitrate controls when needed.

Queue multiple split jobs, track progress, keep a history of recent jobs, and quickly re‑run a previous configuration.

All processing happens locally on your computer — no uploads. Your audiobooks stay private and under your control.
