Do not create large files. Max for satisfactory homemade file playback and performance (skipping out of book and loosing bookmark) is somewhere between 5 and 13.5 hours at 32 kbps if sample rate of iTunes is set to automatic - which results in a 22,050 hz sampling rate. Shorter times required at higher kbps rates.

Utilize free MP3 Book Resizer to split files: Code Monkey's Hosting of MP3 Resizer
If no longer available, $10 Cool MP3 Splitter. Be sure to remove the $7 Extended Download Service (one year download privilege), and back up. There are several sites offering Cool MP3 Splitter at $19.95, so keep looking.

General Notes:

High speed digital dubbing is on when circle under it glows.

1. Drag and Drop or add file(s) to Tunebites,
2. Begin Playing file before starting Tunebites, resetting to start position, and then
3. Click Go in Tunebites.
Beginning the play and resetting before clicking Go avoids a hiccup at the beginning of the resulting file.
Do not run other applications while Tunebite converts. Allow Tunebite full use of computer to prevent distortion of recording. Exit any applications that create voice, bells, or other sounds ("You've Got Mail," for example).

Begin conversion at bedtime or when you will be away for length of original audio divided by the high speed dubbing rate you chose (1X, 2X, 3X, or 4X). I find 4X does not result in a high-quality mp3 recording on my not-so-new computer.
