Compress MP3 and convert to Audio CD

5,357 Views
Last Modified: 2013-11-13
Hi
I have 21 MP3 tracks that contain only spoken text (no music etc.) that I want to convert into an Audio CD format, however, due to the size it would need 4 CDs to fit it all on. I have managed to use Blaze Media Pro (in its 15 day trial) to change the quality of these MP3 files and reduce their size to about one quarter so that they should fit onto one Audio CD. The problem is when I try to do this it wants to expand them back to full size first - using Nero for this.

To reduce the size I reduced the frequency, bitrate and went from stereo to mono. I am aware that I will lose some quality in this conversion but as it is only talking on the tracks I am not too bothered by this. Can anyone suggest a method that would help ne acheive my goals. Also as this is a one-off and non-commercial task I hope to be able to do this with shareware or free software if at all possible.

Many thanks for any help you can provide
Martin

and data cd's, dont forget the good old data discs.
 if you burn these mp3 as data disc readable on pc and most dvd players the new mp3 players, stores a considerable amount of data on a 700 meg cd also retains the original format for easy copy back.
more than 6 hours of music on one cd disc

I also burn my MP3 files  to dvdr  as data discs, as a back up plays fine on dvd player and on pc.
 I can fit 4.7 gig of data which is a lot of mp3.  on one disc.

using Nero

try db powermusic converter to reduce the quality of the mp3s
http://www.dbpoweramp.com/dmc.htm

it will create new copies of the mp3s with reduced quality and nero shouldn't expand them back to full size
also, if you are having xp, you can try the built-in cd burning wizard to create an audio cd

Thanks for the comments so far - my problem is I didn't think about it properly as the Audio CD format it is always going to be 338 minutes long and of course I can fit that amount of MP3 files easily on the CD without compressing them at all.

Sorry
There are 21 MP3 files with a total play time of 338 minutes.

Does the MP3 cd just have the MP3 files copied onto it or is it created with some specific formatting

Thanks for that. It is actually a speaking book. My brother-in-law is the author and has created an MP3 version of his narrating the book. This was done in a studio in France and he was just given the two versions on disk by the studio so that he could run off his own copies. As you suggested I shall use the uncompressed versions of the MP3 files as they are higher quality to start with. In fact I will probably create an ISO for each of the disks to create new ones from. Looks like they will be offering a choice of 1 MP3 disk or 5 Audio CDs to their customers.

I will review all the help and comments here and share out the points accordingly

thanks
