Projects / cdparanoia


cdparanoia reads audio from the CDROM directly as data, with no analog step between, and writes the data to a file or pipe in WAV, AIFC or raw 16 bit linear PCM. Cdparanoia will read correct, rock-solid audio data from inexpensive drives prone to misalignment, frame jitter and loss of streaming during atomic reads. cdparanoia will also read and repair data from CDs that have been damaged in some way.

    Release Notes: Many bugfixes were made. Several updates to match the Linux kernel were made. When using an MMC drive, cdparanoia now attempts to set the DAP bit to request that CD-ROM drives should use hardware interpolation to reconstruct over completely destroyed samples. The cdparanoia tool is now licensed under the GPLv3, the libraries under the LGPLv3.

      Release Notes: Kenwood TruX drives work faster. End-of-track read problems on a number of drives have been alleviated. There is a new -z command syntax with an option argument to allow a skip after a user-configurable number of tries. There are more possible read commands to autoprobe. Support for Linux SCSI Generic 3.x interface has been added, and support for <= 2.0 kernels has been dropped. Starting a new rip will not potentially stall in autoprobe until the previous rip finishes. A segfault that occurred when a device wasn't found has been fixed. Proper /devfs detection in 2.2-2.4 (with or w/o devfsd) has been added. Sample-granulairy offset is allowed.

            Release Notes: The 'ac-' patches to kernel series 2.2.x add a new SG driver by Douglas Gilbert. Unfortunately, the new driver breaks cdparanoia 9.4, this has been fixed in version 9.5.

            I have never had any problems with cdparanoia. It rips even the worst cds that barely played in my home cd player. Great work!

            Quality of rips
            Anyone know a good way to determine how closely a rip matches the original? I'd like to know if a track had skips, scratches, etc. and if those errors will show up in the final WAV file. I'd like to be able to store this information in an file so eventually I could determine the overall quality of my digital recording collection. The documentation on the CDParanoia website indicated that the '-I' option would log errors during the rip to a file, but that option doesn't appear to be in the 9.8 release.

            Re: Printing CD contents
            cdparanoia -eQ 2> filename

            That should do the trick.

            Maybe cdparanoia uses stderr for the output you want, instead of stdout. Using progname 2>file or progname 2>&1>&file would get the output you want to the text file, the former style is recommended. Have fun! ;)
