Abobi

MP3 to M4B with chapters

Only for Mac

Free · In‑App Purchases

Mac

Drop in your MP3s or one long recording. Abobi suggests the chapters, adds the cover and metadata, and exports one M4B for Apple Books — all on your Mac. Abobi turns your audio files into one proper audiobook: a single M4B file with chapters, cover art and complete metadata, ready for Apple Books and other audiobook players. CHAPTERS — THE PART THAT USUALLY TAKES HOURS • Find Chapters suggests the chapter layout for you — even for one long recording with no chapter information. Choose Fast, Balanced or Max. • Every chapter is marked as confirmed, not confirmed or worth a look, so you know where to check. When the narrator announces chapter numbers, a question mark shows where one seems to be missing. • Chapter editor: the whole book at a glance, listen around every boundary, drag markers, add, remove and rename chapters in bulk. Every change can be undone. • Published audiobooks: chapter names from the catalog, applied only when your recording matches the edition. METADATA AND COVER • Look up title, author, narrator, year, description and cover online — then edit any field by hand. • Drag a cover in, paste it from your browser, or find one in a click. Restore the original tags at any time. SOUND THE WAY YOU WANT • Presets from a small voice file to high-quality stereo, with the file size shown before you export. • Lossless ALAC for lossless sources, or no re-encoding at all when your files are already AAC or ALAC. • Even out loudness between files and add a pause between chapters. • Accepts MP3, M4A, M4B, AAC, FLAC, WAV, AIFF, CAF and the sound from MP4, MOV and M4V videos. MADE FOR THE MAC • Export queue: prepare the next book while the previous one is exporting. • File names built from the metadata; projects you can save and reopen. • Interface in 13 languages. • Private by design: your recordings never leave your Mac. Only the title and author are used to look up book details. No account, no analytics, no tracking. FREE TO TRY Export audiobooks up to 90 minutes long for free, with every feature. To remove the limit, buy the full version once and keep it, or get a 7-day pass for a few books. Nothing renews, no account needed. Requires a Mac with Apple silicon. Abobi works with your own DRM-free files. It does not remove copy protection.
