I have been sent from America a couple of CD's containing about 3 EBooks each but the problem is each book is a single MP3 in size from 35- 127 meg

As you can Imagine I cannot burn them to CD for a sight Impaired friend

Does anyone know of a cheap(free preferably) program that will allow me to make chapters without listening to the MP3

I have been told about a prog but can't remember its name that will cut the MP3 to certain lengths but if the chapters aren't say 5mins long won't it cut the word in half

Any help would be very much appreciated

I used to use Goldwave (http://www.goldwave.com/), and if I remember correctly, it has a function to scan for periods of silence, and insert markers for cutting.

Sadly Goldwave isn't free, and I don't know of any freeware software that has a similar function, but others might... ;)

Audacity (http://audacity.sourceforge.net/)

you play the mp3........you select which bit to chop out (export as a new mp3)

why cant you burn them to cd as they are???
you can fit them on a cd as audio

Maybe the smaller ones but 1 is 101meg and in Nero it is 111 mins long
To big for a CD

May I add the lady that the books are for only has a cd player( an old one but she knows how to use it)

I tried to give her a new one that plays MP3 but even tho they look and are used the same she could not get her head around the MP3 player

That is why I am trying to get them cut into Chapters so she can play on her CD player

There's no easy way to do it other than to listen through, I'm afraid, unless you go for something like Goldwave.

If you can get a program which shows the audiotracl as a visual timeline (with peaks and troughs) you can scroll through and look for periods of silence - and check they're the right points) before slicing.

A free demo of some software might be enough.

Audacity will do this mr chris - it is free as well. You can save in different file formats and is relatively easy to use (well - I can use it......:().

thats what audacity does, i load a song up, "see" the sound, find a gap, select a short portion around the gap and play to check its right, then select from the gap right back to the start, export as an mp3 to save the smaller chunk

its not a demo either...its a free FULL program

Go for that, then! :)

I've not really delved into audio software much recently. I always used Premiere when at uni, and that was just for bits and pieces.

If you have a mac get Fission from RogueAmoeba:

http://www.rogueamoeba.com/fission/

Its really easy to use, and has the advantage of NOT re-encoding when you save (so you dont end up losing audio quality). I use it to chop mp3s all the time - I can chop an mp3 into the parts I need in a few seconds, and retain 100% original quality.

Audacity re encodes your mp3 every time you save, so it takes longer and you lose some quality on the way. However it is free and if you don't need to do this often then the time it takes to reencode probably wont bother you. Same with the audio quality - with an audio book its unlikely you will notice the drop in quality.
