I would like to read raw bytes from an Audio CD. For other optical formats like UDF or ISO 9660 I simply use:

$ cat /dev/cdrom | xxd -a | head

But with Audio CD it produces an error:

$ cat /dev/cdrom | xxd -a | head
cat: cdrom: Input/output error

I tried with various Audio CDs, using dd, cat /dev/cdrom > cd.img but it didn't work. The idea was to have a sense of the internal structure of the Compact Disc standard.

OS: Ubuntu. But I could use Windows or Mac if there works.

Another program which can dump raw bytes from a CDROM is safecopy. http://safecopy.sourceforge.net/

Example of a command to get what you want (equivalent to a .bin file of all data in raw mode, minus the TOC):

safecopy -b 2352 -L 2 /dev/cdrom rip.bin

I can't say for sure this'll work as I haven't tried it out. I found the solution on LinuxQuestions forum.

Try using this command:

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

If that doesn't work, try following the instructions here: Howto: Duplicate Audio CDs using cdrdao

You'll have to do it the hard way. Only the first step (extracting Audio CD image) is necessary. The second step is for burning the content to a blank CD.

Instructions from the page:

  • Install cdrdao
sudo apt-get install cdrdao
  • Find your CD-ROM device
  sudo cdrdao scanbus

  Cdrdao version 1.2.3 - (C) Andreas Mueller 
→ /dev/sr0 : Optiarc , DVD RW AD-7590A , 1.52
  • Create the disk image
sudo cdrdao read-cd --source-device /dev/sr0 --driver generic-mmc --paranoia-mode 3 audiocd.toc

Do you mean to create a Wav file for reading raw data for Audio CD? If so, you can get Wav files from Audio-CD by downloading WinDAC or GoldWave or can get Flac files (freerip.com) (recommended).
