NAME¶
cdparanoia - an audio CD reading utility which includes extra data verification featuresSYNOPSIS¶
cdparanoia [options] span [outfile] |-BDESCRIPTION¶
cdparanoia retrieves audio tracks from CDDA-capable CDROM drives. The data can be saved to a file or directed to standard output in WAV, AIFF, AIFF-C or raw format. Most ATAPI and SCSI and several proprietary CDROM drive makes are supported; cdparanoia can determine if the target drive is CDDA capable. In addition to simple reading, cdparanoia adds extra-robust data verification, synchronization, error handling and scratch reconstruction capability.OPTIONS¶
- -A --analyze-drive
- Run and log a complete analysis of drive caching, timing
and reading behavior; verifies that cdparanoia is correctly modelling a
specific drive's cache and read behavior. Implies -vQL.
- -v --verbose
- Be absurdly verbose about the auto-sensing and reading
process. Good for setup and debugging.
- -q --quiet
- Do not print any progress or error information during the
reading process.
- -e --stderr-progress
- Force output of progress information to stderr (for wrapper
scripts).
- -l --log-summary [file]
- Save result summary to file, default filename
cdparanoia.log.
- -L --log-debug [file]
- Save detailed device auto-sense and debugging output to a
file, default filename cdparanoia.log.
- -V --version
- Print the program version and quit.
- -Q --query
- Perform CDROM drive auto-sense, query and print the CDROM
table of contents, then quit.
- -s --search-for-drive
- Forces a complete search for a CDROM drive, even if the
/dev/cdrom link exists.
- -h --help
- Print a brief synopsis of cdparanoia usage and
options.
- -p --output-raw
- Output headerless data as raw 16-bit PCM data with
interleaved samples in host byte order. To force little or big endian byte
order, use -r or -R as described below.
- -r --output-raw-little-endian
- Output headerless data as raw 16-bit PCM data with
interleaved samples in LSB first byte order.
- -R --output-raw-big-endian
- Output headerless data as raw 16-bit PCM data with
interleaved samples in MSB first byte order.
- -w --output-wav
- Output data in Micro$oft RIFF WAV format (note that WAV
data is always LSB-first byte order).
- -f --output-aiff
- Output data in Apple AIFF format (note that AIFC data is
always in MSB-first byte order).
- -a --output-aifc
- Output data in uncompressed Apple AIFF-C format (note that
AIFF-C data is always in MSB-first byte order).
- -B --batch
-
- -c --force-cdrom-little-endian
- Some CDROM drives misreport their endianness (or do not
report it at all); it's possible that cdparanoia will guess wrong.
Use -c to force cdparanoia to treat the drive as a little
endian device.
- -C --force-cdrom-big-endian
- As above but force cdparanoia to treat the drive as a big
endian device.
- -n --force-default-sectors n
- Force the interface backend to do atomic reads of n
sectors per read. This number can be misleading; the kernel will often
split read requests into multiple atomic reads (the automated Paranoia
code is aware of this) or allow reads only within a restricted size range.
This option should generally not be used.
- -d --force-cdrom-device device
- Force the interface backend to read from device
rather than the first readable CDROM drive it finds. This can be used to
specify devices of any valid interface type (ATAPI, SCSI, or proprietary).
- -k --force-cooked-device device
- This option forces use of the old 'cooked ioctl' kernel
interface with the specified CDROM device. The cooked ioctl interface is
obsolete in Linux 2.6 if it is present at all. -k cannot be used
with -d or -g.
- -g --force-generic-device device
- This option forces use of the old 'generic SCSI' (sg)
kernel interface with the specified generic SCSI device. -g cannot
be used with -k. -g may be used with -d to explicitly
set both the SCSI carom and generic (sg) devices separately. This option
is only useful on obsolete SCSI setups and when using the generic SCSI
(sg) driver.
- -S --force-read-speed number
- Use this option explicitly to set the read rate of the CD
drive (where supported). This can reduce underruns on machines that have
slow disks, or which are low on memory.
- -t --toc-offset number
- Use this option to force the entire disc LBA addressing to
shift by the given amount; the value is added to the beginning offsets in
the TOC. This can be used to shift track boundaries for the whole disc
manually on sector granularity. The next option does something similar...
- -T --toc-bias
- Some drives (usually random Toshibas) report the actual
track beginning offset values in the TOC, but then treat the beginning of
track 1 index 1 as sector 0 for all read operations. This results in every
track seeming to start too late (losing a bit of the beginning and
catching a bit of the next track). -T accounts for this behavior.
Note that this option will cause cdparanoia to attempt to read
sectors before or past the known user data area of the disc, resulting in
read errors at disc edges on most drives and possibly even hard lockups on
some buggy hardware.
- -O --sample-offset number
- Use this option to force the entire disc to shift sample
position output by the given amount; this can be used to shift track
boundaries for the whole disc manually on sample granularity. Note that
this will cause cdparanoia to attempt to read partial sectors
before or past the known user data area of the disc, probably causing read
errors on most drives and possibly even hard lockups on some buggy
hardware.
- -Z --disable-paranoia
- Disable all data verification and correction
features. When using -Z, cdparanoia reads data exactly as would
cdda2wav(1) with an overlap setting of zero. This option implies
that -Y is active.
- -z --never-skip[=max_retries]
- Do not accept any skips; retry forever if needed. An
optional maximum number of retries can be specified; for comparison,
default without -z is currently 20.
- -Y --disable-extra-paranoia
- Disables intra-read data verification; only overlap
checking at read boundaries is performed. It can wedge if errors occur in
the attempted overlap area. Not recommended.
- -X --abort-on-skip
- If the read skips due to imperfect data, a scratch, or
whatever, abort reading this track. If output is to a file, delete the
partially completed file.

SPAN ARGUMENT¶
The span argument specifies which track, tracks, or subsections of tracks to read. This argument is required, unless batch-mode is used (in batch-mode, cdparanoia will rip all tracks if no span is given). NOTE: Unless the span is a simple number, it's generally a good idea to quote the span argument to protect it from the shell. The span argument may be a simple track number or an offset/span specification. The syntax of an offset/span takes the rough form: 1[ww:xx:yy.zz]-2[aa:bb:cc.dd] Here, 1 and 2 are track numbers; the numbers in brackets provide a finer-grained offset within a particular track. [aa:bb:cc.dd] is in hours/minutes/seconds/sectors format. Zero fields need not be specified: [::20], [:20], [20], [20.], etc, would be interpreted as twenty seconds, [10:] would be ten minutes, [.30] would be thirty sectors (75 sectors per second). When only a single offset is supplied, it is interpreted as a starting offset and ripping will continue to the end of the track. If a single offset is preceded or followed by a hyphen, the implicit missing offset is taken to be the start or end of the disc, respectively. Thus:- 1:[20.35]
- Specifies ripping from track 1, second 20, sector 35 to the end of track 1.
- 1:[20.35]-
- Specifies ripping from 1[20.35] to the end of the disc
- -2
- Specifies ripping from the beginning of the disc up to (and including) track 2
- -2:[30.35]
- Specifies ripping from the beginning of the disc up to 2:[30.35]
- 2-4
- Specifies ripping from the beginning of track 2 to the end of track 4.
EXAMPLES¶
A few examples, protected from the shell:- Query only with exhaustive search for a drive and full reporting of auto-sense:
cdparanoia -vsQ
- Extract an entire disc, putting each track in a separate file:
cdparanoia -B
- Extract from track 1, time 0:30.12 to 1:10.00:
cdparanoia "1[:30.12]-1[1:10]"
- Extract from the beginning of the disc up through track 3:
cdparanoia -- -3
- The "--" above is to distinguish "-3" from an option flag.
OUTPUT¶
The output file argument is optional; if it is not specified, cdparanoia will output samples to one of cdda.wav, cdda.aifc, or cdda.raw depending on whether -w, -a, -r or, -R is used (-w is the implicit default). The output file argument of - specifies standard output; all data formats may be piped.ACKNOWLEDGEMENTS¶
cdparanoia sprang from and once drew heavily from the interface of Heiko Eissfeldt's (heiko@colossus.escape.de) 'cdda2wav' package. cdparanoia would not have happened without it. Joerg Schilling has also contributed SCSI expertise through his generic SCSI transport library.AUTHOR¶
