NAME
cdparanoia - an audio CD reading utility which includes extra data verification features
SYNOPSIS
cdparanoia [options] span [outfile] |-B
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.
OUTPUT SMILIES
:-) Normal operation, low/no jitter
:-| Normal operation, considerable jitter
:-/ Read drift
:-P Unreported loss of streaming in atomic read operation
8-| Finding read problems at same point during reread; hard to
correct
:-0 SCSI/ATAPI transport error
:-( Scratch detected
;-( Gave up trying to perform a correction
8-X Aborted read due to known, uncorrectable error
:^D Finished extracting
PROGRESS BAR SYMBOLS
<space>
No corrections needed
- Jitter correction required
+ Unreported loss of streaming/other error in read
! Errors found after stage 1 correction; the drive is making the
same error through multiple re-reads, and cdparanoia is having
trouble detecting them.
e SCSI/ATAPI transport error (corrected)
V Uncorrected error/skip
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.
EXAMPLES
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.
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.
