Creating an ISO from an audio cd with dd

glore2002 · 09-18-2008, 07:49 PM

Is it possible to create an ISO from an audio cd with the command dd? If so, please, let me know how?

Thanks,

The same way as you do with a cdrom I think (dd if=/dev/cdrom of=/tmp/file.iso)
dd copies block by block, so it should not care of the nature of the cd, could be audio cd, video cd, photo cd, video game cd... whatever

I don't know what it is you need, but with K3B you can "rip" an audio CD and create mp3 / ogg / whatever files from an audio CD.
These files can later be burned on a new disk with K3B.

I *think* that theoretically it is impossible to copy directly from an audio CD with dd, as there are no data sectors on it. The format of an audio CD is different, like a stream without checksums etc.

Thanks keefaz for your answer.

What you said is what I thought but when I do that, I get the following message:

Code:

dd: reading `/dev/cdrom': Input/output error
0+0 records in
0+0 records out
0 bytes (0 B) copied, 0.00227296 s, 0.0 kB/s

I think you're right. So I will go back to k3b.

I think you are right niels.horn

I suggest use: cdparanoia -vsQ
this will copy the CD tracks in current directory, then you can make a CD audio from those tracks. Or use k3b

Nice tip!

I've used:

Code:

cdparanoia -B -- "-12"

This outputs each track on a different file. From track 1 up to track 12.

Is there a way to convert them to mp3 directly when extracting the tracks?

Thank you!

You will need lame for that. I recommend using rubyripper instead. http://code.google.com/p/rubyripper/

Audio CDs don't contain filesystems. They actually resemble phono tracks, which spiral inward and have gaps to mark the track boundaries.

I say the best tool for this is cdrdao:

Code:

cdrdao read-cd --device /dev/cdrom --datafile image.bin

I am sure I am missing something (parameter or so) but when I execute:

Code:

cdrdao read-cd --device /dev/cdrom --datafile image.bin

It displays the following error message:

Code:

ERROR: Missing toc-file.

This happens with both, Audio and Data CDs.

Thanks,

Try leaving out the '--datafile', and this will only work for audio cds.
You can use dd, but you will NOT get an iso. Why ? Because audio CDs don't have a filesystem, and it's .iso because it has iso9660 filesystem, not the case for audio CDs.

Thanks for your reply!

Once I have the image, are this commands fine to burn that image to an empty CD?

$> cdrdao write --device /dev/cdrom image.bin

Yes, I think that would work, but instead of 'image.bin' you should use the name of the toc file.

Thanks H_TeXMeX_H for your suggestion.

Finally, as a conclusion, I will tell you what worked for me.

I've used the following commands to create and to record an image CD or DVD. This works for audio as well as for data.

a) To create image:

Code:

$> cdrdao read-cd -v 2 --device 1,0,0 --read-raw --datafile imagen.bin imagen.toc

b) To record image:

Code:

$> cdrdao write -v 2 --device 1,0,0 --speed 4 --buffers 64 imagen.toc

Thanks to all of you for helping me.
