Split audiobooks your way: use automatic chapter detection, split at silence, fine-tune custom segment lengths, or choose an exact count with Even Split.
**ChapterSplit — Split Audiobooks into Chapters**
Turn long audiobook recordings into individual chapter files with ChapterSplit. Import MP3, M4A, AAC, FLAC, WAV, or OGG audio and split it into manageable chapters—quickly, privately, and with control over how your files are divided.
**Choose How to Split**
• **Auto (Recommended):** Automatically checks for embedded chapter markers, then uses silence detection when needed.
• **Chapters (Metadata):** Uses embedded chapter markers to preserve the original chapter boundaries and titles. Optionally divide longer chapters into smaller segments.
• **Silence Detection:** Finds natural pauses between chapters, with adaptive detection to accommodate different recordings.
• **Even Split:** Divide audio into a chosen number of approximately equal-length parts.
**Smarter Silence Detection**
Not every audiobook has clear pauses. ChapterSplit's Auto and Sensitive detection presets automatically explore suitable silence settings to find better chapter boundaries.
Want more control? Choose Custom to fine-tune silence sensitivity, pause duration, and segment lengths.
**Designed for Real-World Audiobooks**
• Preserve embedded chapter markers and titles when available.
• Choose to export a single file or use silence detection when no chapter markers are found.
• Preserve cover artwork in your output files.
• Customise chapter numbering, including 2-digit or 3-digit numbering and track numbers.
• Continue chapter numbering across multiple input files.
• Use optional Safer Encoding for broader playback compatibility.
• Re-run previous jobs with their saved settings.
**Supported Audio Formats**
Import common audio formats including MP3, M4A, AAC, FLAC, WAV, and OGG.
**Private by Design**
Your audio files are processed locally on your Mac. ChapterSplit doesn't require uploading your audiobooks to a cloud service.
**Free & Pro**
Try ChapterSplit for free with up to 2 output chapters per file, subject to Free mode limits. Upgrade to ChapterSplit Pro to unlock unlimited chapter splitting and additional features.
