NAME

       cd-paranoia  9.8  (Paranoia  release  III  via  libcdio)  - an audio CD
       reading utility which includes extra data verification features

SYNOPSIS

       cd-paranoia [options] span [outfile]

DESCRIPTION

       cd-paranoia retrieves audio tracks from  CDDA  capable  CD-ROM  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
       CD-ROM  drive  makes  are  supported;  cd-paranoia can determine if the
       target drive is CDDA capable.

       In addition to  simple  reading,  cd-paranoia  adds  extra-robust  data
       verification,    synchronization,    error    handling    and   scratch
       reconstruction capability.

       This version uses the libcdio library for  interaction  with  a  CD-ROM
       drive.  The jitter and error correction however are the same as used in
       Xiph’s cdparanoia.

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 CD-ROM drive autosense, query and print the CD-ROM 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 cd-paranoia usage and options.

       -l --log-summary file
              Save result summary to file.

       -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;  cd-paranoia  will  split  the
              output  into  multiple  files  at track boundaries.  Output file
              names are prepended with ’track#.’

       -c --force-cdrom-little-endian
              Some CD-ROM drives misreport their endianness (or do not  report
              it  at  all);  it’s  possible that cd-paranoia will guess wrong.
              Use -c to force cd-paranoia to  treat  the  drive  as  a  little
              endian device.

       -C --force-cdrom-big-endian
              As  above  but  force  cd-paranoia  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 CD-ROM drive it finds containing  a  CD-DA  disc.
              This  can be used to specify devices of any valid interface type
              (ATAPI, SCSI or proprietary).

       -g --force-generic-device device
              This  option  is  an  alias  for  -d   and   is   retained   for
              compatibility.

       -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
              cd-paranoia  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
              Some CD-ROM/CD-R drives will add an offset to  the  position  on
              reading audio data. This is usually around 500-700 audio samples
              (ca. 1/75 second) on reading.  So  when  cd-paranoia  queries  a
              specific  sector,  it might not receive exactly that sector, but
              shifted by some amount.

       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 if you are
       ripping  something  including  the  ending  of  the CD (e.g. the entire
       disk), this option will cause cd-paranoia to attempt  to  read  partial
       sectors  before or past the known user data area, 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, cd-paranoia 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.

       -x --test-flags mask
              Simulate CD-reading errors. This is used in regression  testing,
              but  other uses might be to see how well a CD-ROM performs under
              (simulated) CD degradation. mask specifies the artificial  kinds
              of  errors  to  introduced;  "or"-ing  values from the selection
              below will simulate the kind of specified failure.

          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:

              cd-paranoia -vsQ

       Extract an entire disc, putting each track in a seperate file:

              cd-paranoia -B

       Extract from track 1, time 0:30.12 to 1:10.00:

              cd-paranoia "1[:30.12]-1[1:10]"

       Extract from the beginning of the disc up to track 3:

              cd-paranoia -- "-3"

       The "--" above is to distinguish "-3" from an option flag.

OUTPUT

       The  output  file  argument  is  optional;  if it is not specified, cd-
       paranoia 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

       cd-paranoia  sprang  from  and  once drew heavily from the interface of
       Heiko Eissfeldt’s (heiko@colossus.escape.de)  ’cdda2wav’  package.  cd-
       paranoia would not have happened without it.

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