Audio CD Preservation
A large collection of, predominantly audio, CDs needs preserving. The CD's initially need stabilising onto magnetic storage medium to prevent preservation issues relating to disc-rot. The content of these disc images then needs to be extracted and catalogued. The following discusses a number of tools to tackle the first part - disc stabilisation.
The following two tools provided the ability to create a disc image (.bin/.iso with .cue track listings file) of an audio CD with mechanisms to extract tracks to WAV files.
One solution on Linux/Ubuntu was to read a binary from the CD using cdrdao using the following command from the mounted cdrom device (here /dev/cdrom):
- GUI based tool (although I believe it can be used as a command line tool also)
- Successfully creates .iso/.cue combination of audio CD
- ISOBuster can open the .cue file, display track listing and extract .wav files for each audio tracks
- Commercial product
- There are 3 versions with different levels of functionality (free; personal - US$40 and professional - US$60)
- From what I can gather from the above link, the free version can be used anywhere, even for commercial purposes.
.cue file - metadata
ISOBuster generates a .iso/.cue file pair as a audio CD disc image. Here is the contents of the .cue file generated for a 4-track audio CD (note there is no descriptive metadata about the tracks or the disc itself):
Other tools that were considered and/or tested
- Installed self-booting image onto USB drive
- Rebooted laptop and booted from USB drive
- OSFClone tool cannot "see" CD drive (on laptop)
- It could see USB drives and hard drives, just not the CD drive
- Could try a USB CD drive?
aimage (Ubuntu linux - live disk via bootable USB)
- Install via afflib-tools package (sudo apt-get)
- Tool can create AFF files
- Used this tool to create an AFF image from a Data CD; the image is mountable (and accessible) via OSFMount
- No successful creation of an audio CD AFF image
- I suspect the linux device (/dev/loop) I thought was the CD device was actually pointing to something else
- Installed on a Ubuntu live disk via bootable USB
- Creates AFF, EWF and DD image files
- A scan of drives would show the CD drive, however when trying to capture an image, the tool reports errors (bad sectors, I think).
- Tool not tried
- Mentions guymager, hence testing of that tool
Whilst it is possible to use the laptop's CD drive with a data CD in a Linux VM image (Ubuntu 12.04), it seems that VirtualBox cannot "passthrough" audio CD's from the host CD drive to the VM guest. This essentially prevents any use/testing of linux disk imaging tools via a VM image using VirtualBox (for audio CDs).
