cd-paranoia(1)
NAME
cd-paranoia 9.8 (Paranoia release III via libcdio) - an audio CD reading utility which includes extra data verification features
SYNOPSIS
cd-paranoia [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. This version uses the libcdio library for interaction with a CD-ROM drive. The jitter and error correction however are the same as used in Xiph's cdparanoia.
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.
-l --log-summary file
Save result summary to file.
-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
OUTPUT SMILIES

same error through multiple re-reads, and cd-paranoia is having
trouble detecting them.

V Uncorrected error/skip
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.
