cdparanoia - an audio CD reading utility which includes extra data
verification features
cdparanoia [options] span [outfile]
|-B
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.
- -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.

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.
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.
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.
