Audiobook Builder2.2.9

Audiobook Builder combines audio CDs and existing audio files into audiobooks for iPhone, iPad, and other Apple devices. It condenses material that might otherwise appear as hundreds or thousands of music tracks into one or a few audiobook tracks in Books, Music, or iTunes.

When importing a CD, it automatically ejects the disc and prompts for the next one, while already-ripped tracks can be dragged directly into a project. M4A and M4B files with compatible audio formats can be joined without re-encoding, and other common formats such as MP3 are supported. Users can organize files into chapters with custom names and artwork, then choose a built-in quality preset or adjust quality settings themselves. AAC suits higher data rates and music-heavy works, while HE-AAC provides good spoken-word quality at lower data rates.

Projects copy their source audio into a document file, allowing work to pause and resume later, or be moved between Macs. Audiobooks can also be dragged from Music or iTunes into Audiobook Builder and built directly back to Books, Music, or iTunes, making it useful for personal CD collections, narrated files, and listening during commutes, exercise, or travel. The interface supports English, Deutsch, Svenska, Русский, Português, and Español.

The freeware version 2.2.9 runs on macOS, supporting OS X 10.11 El Capitan and later, with full support for macOS 15 Sequoia and a recommendation of macOS 11 Big Sur or later. It runs on Intel and Apple Silicon processors and is designed for Mac rather than Microsoft Windows or Linux.
