Hi. Apologies in advance, but I don't have links for most of this software. Also, I can only comment on Windows. There are many easy ways to convert to mp3. Probably the easiest is something like TextAloud but I don't know how much it is and I don't use it. What I do is use an audio capture program. In other words, it records anything from the sound card output, whether MIDI, RA, etc. to wave or mp3. The problem is that it does this in real time so if the book is 10 hours long, it takes that long to record. This probably doesn't help, but newer OCR programs for the blind such as Kurzweil 1000 version 6 and up and newer versions of Openbook have this built-in. They will convert text to mp3 relatively quickly. If you have a specific book you want converted, I will do it for you. Write me off list. The particular capture program I use is RecAll. It is shareware but there are free alternatives. You can go here if you want a 30 day demo. http://www.sagebrush.com/
