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.

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.  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.
