Audio CD from mp3 File


I want to burn an audio disk (playable on CD player) from a single mp3 file using cdrecord. I can write an error-free disk with
cdrecord -v -pad -dao -audio Lessons_Carols_2013.mp3 but it plays only hash.

Conversion of the mp3 to a .wav file gives a file >700 Mb; too big for the disk.

Am I stuck? The more I read the less I know.

And that is most likely your problem. Audio-CDs store the audio data uncompressed, similar to the WAV format. So most likely your file is simply to large for a CD. You will get a better view of this if you use CD burning applications like K3B, they usually have a visual indicator about the size of the disk and your files.

Hi
Check the duration of that mp3 file.
Usually needs to be <= 80 minutes for an audio CD.

If it's > 80 minutes, trim it with a command like this... (-t hh:mm:ss)
Code:
ffmpeg -i Lessons_Carols_2013.mp3 -f wav -t 01:20:00 Lessons_Carols_2013.wav
Then burn the wav file to CD using cdrecord or whatever.

With my system the command is:-
Code:
cdrecord -v dev='/dev/sg0' -audio Lessons_Carols_2013.wav

there's also something called "overburning" which allows you to go over the limit of 650/700MB, up to 740 iirc (or 80min).
nowadays i think it's pretty safe to use that.

At one time the only OS I knew of that could create a real audio cd was BeOS. Not sure any can still replicate a real audio cd format.

Thanks to all for insights into my problem. It's true, size matters. The mp3 file has a play time of 77 min and is 71 Mb in size. The converted wav file is well over 700 Mb. I hate to trim off the beginning or end of the performance to make a CD. Looks like I'm out of luck on this one.

Thanks again
