The Mac edition is the deep end: more formats out, more books at once, more keyboard.
Drop a whole folder of MP3s — or a video file — straight onto the window. CUE sheets dropped alongside become chapters automatically.
Every window is an independent project. Work through a whole series without losing your place in any book.
The direct-download edition bundles the LAME encoder for MP3 output with full ID3 chapter markers — for players that never learned M4B.
Hook up the open-source exhale encoder — one click builds it from source — and export books at roughly half the size of AAC with the same speech quality.
Select files and join them into one chapter — or split them back — right from the toolbar. Space previews the selection, menus carry shortcuts.
Tidy folder structures like Author/Series/1 — Title (Year) pre-fill the book's metadata before you type a thing.
Expand any chapter to see exactly which source files it contains. Join and Split reshape the book in a click, and every title edits inline.
Presets for common cases, full manual control for the rest — and a live input → output summary with an estimated file size, so there are no surprises when the export lands.
