Voxbound / Guides

Audiobook guides for Windows

How to make, fix and convert M4B audiobooks on Windows. Where there's a free way, usually FFmpeg, the guide shows it alongside Voxbound.

Make an audiobook

• How to combine MP3 files into one M4B audiobook with chapters: turn a folder of MP3s into one M4B with chapters, tags and a cover, with Voxbound or free with FFmpeg.
• Best M4B settings for Audiobookshelf, Prologue and Apple Books: the format, bitrate, chapters, cover and tags each player needs, with sources.

Fix a problem

• M4B chapters not showing in Apple Books or Audiobookshelf: how to check a file's chapters, and how to fix the common reasons they don't show.

Convert and compare formats

• How to convert an M4B audiobook to MP3: one MP3 that keeps the chapters, or one MP3 per chapter, with tested commands.
• M4B vs M4A vs MP3 for audiobooks: what each format holds, how to check a file, and when renaming is enough.

Choose a tool

• Choosing an audiobook merger for Windows: what to compare, answered for Voxbound and for FFmpeg by hand, and when a free tool is enough.
