ChapterSplit
Split Large Mp3/m4a Audiobooks into Chapters on Windows

Detects chapters from embedded metadata, finds natural breaks using silence detection, or automatically chooses the best method — all powered locally by FFmpeg with progress feedback, cover‑art preservation, and clean output naming.

Features
Auto Chapter Detection
Choose Auto, Embedded Chapters, or Silence Detection. ChapterSplit can read chapter markers from metadata or detect natural breakpoints by analyzing silence patterns.
Silence Analysis with Live Feedback
During silence detection, the app reports analysis progress (time elapsed, estimated remaining, and scan speed) so you always know what it’s doing.
Preserve Cover Art & Tags
Keeps cover art (when available) and writes sensible metadata for each exported chapter, including optional track numbers.
Clean Output Naming & Numbering
Generate consistent filenames with 2‑ or 3‑digit numbering, optional chapter prefixes, and the option to continue numbering across multiple input files.
Safer Encoding Mode
Optional ‘safer’ encoding settings for maximum compatibility, including fixed sample rate and bitrate controls when needed.
Batch Jobs, Queue & History
Queue multiple split jobs, track progress, keep a history of recent jobs, and quickly re‑run a previous configuration.
Privacy First, Offline Processing
All processing happens locally on your PC — no uploads. Your audiobooks stay private and under your control.
