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.
