Hi back to you, Wu, from Frank Fitzpatrick,
In answer to your question . . . it depends on a few things.

In hours and minutes, how long is the audio when read at the speed you 
Or,to calculate the total time needed, how many total pages are there 
and how long does it take to read an average length page?

Secondly, would  the mp3 file format be of high enough quality? 
Personally, I would say yes, because spoken words do not have the wide 
frequency range needed for  music.

So, if you use a good quality setting for mp3 files and burn them to a 
CD-R, you can get 10-15 times as much audio on the disk than you do 
with a standard 16 bit AUDIO FILE Redbook format. I recently used a 
quite high quality setting of 16 bit and 192 for mp3 files and put 2 
and a half hours of flute with piano music on a CD-R, only using 135 
megabytes of the 650 available on the CD. And this was in stereo with a 
higher rate than you would likely need. I could get 5 hours on one 650 
MB CD. I use the 650s for the highest compatibility with older CD 
players. With a lesser but still good quality mp3 setting, you should 
be able to burn 7 hours. But (disclaimer, disclaimer) try this first 
before committing to it, I advise.

To burn the CD I used Toast 6 by Roxio - for my Mac. If you use a PC, 
I'm sure that Roxio's Easy CD Creator burns mp3s also.

To convert AIFF or WAVE files to mp3 format, I use cheap shareware 
called Audio Hijack on my Mac. There are many mp3 encoders available 
for PCs. Try a search on http://www.google.com for them; just type in - 
mp3 encoder - in the search field. Likely you will find a FREE encoder 
and some very cheap ones, too.

Before Toast could burn mp3s, I believe you could trick it into doing 
so. I used to use this trick to burn AIFF files to CD as AIFF backups 
without the software automatically changing the files to Audio Redbook 
format. I chose Data Format, next put a tiny data file such as a 4 KB 
empty word processing file FIRST in the window, and then added my AIFF 
files. This fooled Toast into creating a Data Format CD instead an 
Audio one. I wonder if this might even work with DVD burners! If that 
is so (Try before you commit to this) your problems are over if a DVD 
player will then read it.  . . . Sorry, this part was just 

Does any of this help you?
