NAME

       cdparanoia - an audio CD reading utility which includes extra data verification 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 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

       -A --analyze-drive
	      Run and log a complete analysis of drive caching, timing and reading behavior; verifies that cdparanoia  is  correctly  modelling  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 reading 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 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 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  specify
	      devices of any valid interface type (ATAPI, SCSI, or proprietary).

       -k --force-cooked-device device
	      This  option  forces  use of the old 'cooked ioctl' kernel interface with the specified cdrom device.  The cooked ioctl interface is
	      obsolete in Linux 2.6 if it is present at all.  -k cannot 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 use-
	      ful 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  some-
	      thing 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 bound-
	      aries 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 par-
	      tially 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  trou-
	      ble 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 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 sin-
       gle 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, 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.
