NAME
       cd-paranoia - 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
       -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 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.


       -h --help
	      Print a brief synopsis of cd-paranoia usage and options.


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


       -L --log-debug file
	      Save detailed device autosense and debugging output to a 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 Microsoft 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.


       -E--force-overread
	      Force overreading into the lead-out portion of the disc. This
	      option is only applicable when using the +.B -O +option with a
	      positive sample offset value. Many drives are not capable of
	      reading into this portion of the disc and attempting to do so on
	      those drives will produce read errors and possibly hard lockups.


       -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.

	    0x10  - Simulate under-run reading

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

	      No corrections needed

	  -   Jitter correction required

	  +   Unreported loss of streaming/other error in read

	  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 separate 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.
