    I'm trying to convernt Audible books (.aa format) into several small mp3's. The Audible book section is large - about 87 megs. I then convert it to mp3 format and the file size increases to about 200 megs.

    I then split the mp3's into 20 meg sections, and Winamp plays the smaller files without problems.

    However, when I try to burn the files onto a CD, my CD burning software makes me chose between "music" and "data". When I chose "music", a 20 meg file becomes about a 250 meg file on the cd. It plays fine on my portable CD player. When I chose "data", the file stays at 20 megs, but I now can't play the CD on anything other than my computer.

    Of course, I want the smaller file size to fit more of the audio book onto the CD.
    Anyone know why the mp3 size increases when I burn the file onto the CD?

    I just tried to burn the same files using Windows Media Player - same problem. I can only fit one 20-meg file onto an entire CD, since the size expands on the CD. Weird.

    I have never encountered such a problem, but my guess is that when you chose "music", the MP3 is converted into a .wav-file. Wav is the standard format for music on CDs, it is about 10 times larger than the same music in MP3 (fits your case). If you burn it as MP3, you have a smaller file size, but you can only listen to it if your CD player can handle MP3 which is not necessarily the case.

    If you use Windows Media Player 10.0 you may be able to rip the audio book right to mp3.

    Thats what I reckon is happening too. MP3 is a compressed format, .wav isnt so it is allways bigger..
    Pretty amazing that the .aa file is so small though! prob. because it is spoken word only they can compress it more..

    Do files get embarrassed when they get unzipped?

    Thanks for everyone's input. It sounds like I don't have a solution to listen to the smaller files directly on the CD with the equipment I have.

    My problem arose because I recently sold my 600 to fund my upcoming GMS 650 purchase. (If I had to do it all over again, I would wait - I can't stand being Treo-less).

    Without the 600, I couldn't listen to my audiobooks without burning at about 20 CD's for a single book - not a workable solution. However, I spent a couple of hours digging through boxes and found my old mp3 player with 64 megs of memory. I'm using it to listen to my audible files until my 650 is available.

    Do you have a DVD burner?
    It might be possible to burn it on a DVD and listen it from that..

    You are actually decompressing from one format to another at each stage. This is usually a very bad method and causes large loss of sound fidelity, but if it's only audio books, it might be ok. Wav file on CDs are completely uncompressed files. CD must be burned as wavs if you want them to be usable on any audio CD player. If you want to save as mp3 or whatever, you need to use a player that supports mp3. I don't the difference in the compression codec between mp3 and .aa but I assume mp3 has worse codec and as result gets larger...
