This is an inAudible lossless TrueDecrypt, ripped directly from the Audible AAX to create one .m4b file. No transcoding or re-encoding (and therefore a loss of quality) was done in this process. The .m4b audiobook is chapterised by hand. I have used my copy of the book for the exact chapter titles. It looks fantastic when using a playback device that supports .m4b chapters.
