On a Linux system, I am intending to convert some audio files (mp3) and write them to an audio CD. Instead of directly writing to an optical disk, I would prefer to somehow redirect the output to an image file which can be burned later.

Specifically, I attempted the following steps:

  1. create a file to be written to (700 MiB, 777 permissions)

    dd if=/dev/zero of=./cd.img bs=$((1024 * 1024)) count=700

  2. attach file to loop device (/dev/loop0, as root)

    losetup --sizelimit 700MiB /dev/loop0 ./cd.img

  3. use mp3cd software to convert, normalize ... and ultimately write audio files to audio CD (as root)

    mp3cd --verbose --driver generic-mmc-raw --device /dev/loop0 ./audio/{01..03}.mp3

mp3cd fails on its last step, "burn". The file /tmp/mp3cd-root/tool-output.txt contains a hint that an SCSI command inquiry on /dev/loop0 failed. Most likely, I am missing some options in the losetup command.

In addition to achieving the image creation in this particular case of an audio cd, I would be thankful for some pointers on how images for data CDs/DVDs could be prepared in a similar way.

Have you tried passing the option -n to mp3cd?

On the man page http://outflux.net/unix/software/mp3cd/mp3cd.html :

-n, --simulate Don't actually burn a disc but do everything else.
