NAME
cdparanoia (Paranoia release III) - an audio CD
reading utility which includes extra data verification features
DATE
version III release alpha 9.8 (02 Mar 2001)
SYNOPSIS
cdparanoia [options] span
[outfile]
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, 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
- -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 CDROM drive autosense, 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 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 CDROM drive it finds. This can be used to
specify devices of any valid interface type (ATAPI, SCSI or
proprietary).
- -g --force-generic-device device
- This option is used along with -d when one wants
explicit control in setting both the SCSI cdrom and generic devices
seperately. This option is only useful on non-standard SCSI setups.
- -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 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 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.

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:
-
cdparanoia -vsQ
- Extract an entire disc, putting each track in a seperate 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 to 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.
