Description
AudioBo turns audio files into real M4B audiobooks — with proper chapters, clean metadata, and reliable long-form playback.
MP3 files work well for music, but fall apart for audiobooks: no true chapter support, unreliable bookmarks, and inconsistent resume behavior. AudioBo builds real M4B audiobooks instead — the format designed specifically for long-form listening.
M4B supports chapters, bookmarks, and clean navigation in Apple Books, Music, CarPlay, and even classic iPods. AudioBo produces correctly structured M4B files — not repackaged audio that only looks like an audiobook.

TECHNICAL DETAILS (FOR THE CURIOUS)
AudioBo works with the formats people actually have. You can bring in MP3, AAC (M4A), OGG, WAV, WMA, WV, APE, FLAC, Opus, or AIFF.
Audio encoding options:

- Mono or stereo, based on your source
- Bitrates from 16 to 320 kbps

- Works smoothly with Plex, BookPlayer, VLC, Audiobookshelf, and most audiobook apps
- Fully supported on Android and Windows through any modern audio player
