I am afraid that I may be one of the resident Audio Books (or Audio eBook) experts around here...

I am very short time now... sorry... But, if you need to reduce the size of Audio eBooks, please click on the CDex1.51 link in my sig below...

It's FREE...

Download and install the software -To A Folder You Have FIRST Created in Program Files - and then run it.... you can convert almost any file type to any other and, most important, you will be able to reduce the 'size' of Audio eBook files - .mp3s normally -

For speech-type audio you do not need a very high bandwidth...

Try converting your existing Audio eBooks to 32k files...

Loads more later regarding eBooks of all types...
