NAME
cdparanoia 9.8 (Paranoia release III libcdio) - an
audio CD reading utility which includes extra data verification
features
SYNOPSIS
cdparanoia [options] span
[outfile]
DESCRIPTION
cd-paranoia retrieves audio tracks from
CDDA capable CD-ROM drives. The data can be saved to a file or
directed to standard output in WAV, AIFF, AIFF-C or raw format.
Most ATAPI, SCSI and several proprietary CD-ROM drive makes are
supported; cd-paranoia can determine if the target drive is
CDDA capable. In addition to simple reading, cd-paranoia
adds extra-robust data verification, synchronization, error
handling and scratch reconstruction capability.
OPTIONS
- -v --verbose
- Be absurdly verbose about the autosensing 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).
- -V --version
- Print the program version and quit.
- -Q --query
- Perform CD-ROM drive autosense, query and print the CD-ROM
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 cd-paranoia 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; cd-paranoia will split the
output into multiple files at track boundaries. Output file names
are prepended with 'track#.'
- -c --force-cdrom-little-endian
- Some CD-ROM drives misreport their endianness (or do not report
it at all); it's possible that cd-paranoia will guess wrong. Use
-c to force cd-paranoia to treat the drive as a little
endian device.
- -C --force-cdrom-big-endian
- As above but force cd-paranoia 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 wihin 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 CD-ROM drive it finds containing a CD-DA
disc. This can be used to specify devices of any valid interface
type (ATAPI, SCSI or proprietary).
- -g --force-generic-device device
- This option is an alias for -d and is retained for
compatibility.
- -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 with 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 cd-paranoia 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
- Some CD-ROM/CD-R drives will add an offset to the position on
reading audio data. This is usually around 500-700 audio samples
(ca. 1/75 second) on reading. So when cd-paranoia queries a
specific sector, it might not receive exactly that sector, but
shifted by some amount. 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 if you are ripping something including the
ending of the CD (e.g. the entire disk), this option will cause
cd-paranoia to attempt to read partial sectors before or past the
known user data area, 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, cd-paranoia reads data exactly as would cdda2wav
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, whatever,
abort reading this track. If output is to a file, delete the
partially completed file.
- -x --test-flags mask
- Simulate CD-reading errors. This is used in regression testing,
but other uses might be to see how well a CD-ROM performs under
(simulated) CD degradation. mask specifies the artificial kinds of
errors to introduced; "or"-ing values from the selection below will
simulate the kind of specified failure.
0x10 - Simulate under-run reading

SPAN ARGUMENT
The span argument specifies which track, tracks or subsections
of tracks to read. This argument is required. 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 preceeded 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 and
preceeding hyphens from the shell.
EXAMPLES
A few examples, protected from the shell:
- Query only with exhaustive search for a drive and full
reporting of autosense:
-
cd-paranoia -vsQ
- Extract an entire disc, putting each track in a seperate file:
-
cd-paranoia -B
- Extract from track 1, time 0:30.12 to 1:10.00:
-
cd-paranoia "1[:30.12]-1[1:10]"
- Extract from the beginning of the disc up to track 3:
-
cd-paranoia -- "-3"
- The "--" above is to distinguish "-3" from an option
flag.
OUTPUT
The output file argument is optional; if it is not specified,
cd-paranoia 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
cd-paranoia sprang from and once drew
heavily from the interface of Heiko Eissfeldt's (heiko@colossus.escape.de)
'cdda2wav' package. cd-paranoia would not have happened without it.
Joerg Schilling has also contributed SCSI expertise through his
generic SCSI transport library.
