CDPARANOIA(1)               General Commands Manual              CDPARANOIA(1)



NAME
       cdparanoia - an audio CD reading utility which includes extra data ver-
       ification 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  propri-
       etary  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  veri-
       fication,  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 model-
              ling a sprcific drive's cache and read behavior. Implies -vQL.


       -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 read-
              ing 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 autosense and debugging output to a file,
              default filename cdparanoia.log.


       -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 out-
              put 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 spec-
              ify devices of any valid interface type (ATAPI, SCSI, or propri-
              etary).


       -k --force-cooked-device device
              This  option  forces use of the old 'cooked ioctl' kernel inter-
              face with the specified cdrom device.  The cooked  ioctl  inter-
              face  is obsolete in Linux 2.6 if it is present at all.  -k can-
              not 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  cdrom  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  which
              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  posi-
              tion 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 cor-
              rect

         :-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
       <&lt;space>&gt;
              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 bach-mode, cdparanoia will rip all traks  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 speci-
       fication.  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 speci-
       fied: [::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
       autosense:

              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, cdpara-
       noia 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   (heikoATcolossus.de)   'cdda2wav'   package.
       cdparanoia would not have happened without it.

       Joerg Schilling has also contributed SCSI expertise through his generic
       SCSI transport library.
