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.
description
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.
acknowledgements
cdparanoia sprang from and once drew heavily from the
interface of Heiko Eissfeldt’s
(heiko[:at:]colossus.escape[:dot:]de) ’cdda2wav’ package.
cdparanoia would not have happened without it.
Joerg Schilling has also contributed SCSI expertise through his
generic SCSI transport library.
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.

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.
