What is read

1. Sun Tzŭ said: The art of war is of vital importance to the State. 2. It is a matter of life and death, a road either to safety or to ruin. Hence it is a subject of inquiry which can on no account be neglected. 3. The art of war, then, is governed by five constant factors, to be taken into account in one’s deliberations, when seeking to determine the conditions obtaining in the field. 4. These are: (1) The Moral Law; (2) Heaven; (3) Earth; (4) The Commander; (5) Method and discipline. 5, 6. The Moral Law causes the people to be in complete accord with their ruler, so that they will follow him regardless of their lives, undismayed by any danger.

[The commentators, I think, make an unnecessary mystery of two words

here. Meng Shih refers to "the hard and the soft, waxing and waning" of

Heaven. Wang Hsi, however, may be right in saying that what is meant is

"the general economy of Heaven," including the five elements, the four

seasons, wind and clouds, and other phenomena.]

Words split with a hyphen at the end of a line are joined again, and a paragraph that runs over a page break is read as one, the way you would read it yourself.

Turn bookmarks into chapters

PDF bookmarks become chapters with their own titles. Without bookmarks, chapter headings in the text are found, so a 300 page PDF arrives as tidy tracks.

Which PDFs convert best

If you can highlight a sentence in your PDF reader, the converter can read it. PDFs saved from Word, Google Docs, Pages, LaTeX, InDesign and ebook tools all carry their text, chapter titles and often bookmarks.

Reports, theses, manuals, course packs and ebooks published as PDF all make good listening, from a ten page paper to a long textbook.

What the cleanup removes

A printed page carries things nobody reads aloud: the running header with the book title, the page number, footnote markers, and the list of references at the end of a paper. The converter spots text that repeats on every page and leaves it out of the narration.

Figure captions are kept in the word count but left out of the reading, so a description of a chart never interrupts a sentence.

Turn a PDF into an audiobook for study

Students use PDF to audiobook conversion to get through reading lists on the bus, at the gym or while cooking. Each chapter is its own track, so it is easy to replay the one you need before a seminar.

Listening while following the text helps many readers remember more, and it gives tired eyes a break during exam season.

PDF to MP3 or M4B

Choose MP3 when you want a file per chapter that plays everywhere: phones, car stereos, smart speakers and any media player. Choose M4B when you want one audiobook file with chapter marks and a cover, which Apple Books and audiobook apps show as a chapter list.

You can make both from the same narration, so there is no need to decide before you start.

  • 3 chapter marks

Listen faster, finish sooner

Most audio players let you listen at 1.25x or 1.5x, and narration stays clear at those speeds. The audiobook calculator shows how long your document takes at each speed, and the day you will finish at an hour a day.

Chapter files make speed listening easy to manage: skip back one track to hear a section again without hunting for the place.

What a PDF costs to narrate

One credit narrates 1,000 characters, which is about half a page of a typical book, so a page costs about 2 credits. A 30 page report takes around 60 credits and a 300 page book around 600.

The converter counts the exact characters before you start, after the page numbers and headers are taken out, and you only spend credits on the chapters you get.
