cdparanoia (1)
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
-
Cdda2wav-style batch output flag; cdparanoia will split the output into multiple files at track boundaries. Output file names are prepended with 'track#.'
- -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.
Again, don't forget to protect square brackets from
the shell.
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.
