NAME cdparanoia 10.2 (Paranoia release III) - an audio CD reading utility which includes extra data verification features
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 veri- fication, 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 mod- elling a sprcific drives 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 read- ing 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).
Cdda2wav-style batch output flag; cdparanoia will split the out- put 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); its 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 pro- prietary).
-k --force-cooked-device device This option forces use of the old cooked ioctl kernel inter- face with the specified cdrom device. The cooked ioctl inter- face is obsolete in Linux 2.6 if it is present at all. -k can- not 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 seperately. This option is only useful 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 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 posi- tion 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 cor- rect
:-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, its 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 speci- fication. The syntax of an offset/span takes the rough form:
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.], etc, would be interpreted as twenty seconds, [10:] would be ten minutes, [.30] would be thirty sec- tors (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 off- set 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:
Extract an entire disc, putting each track in a seperate file:
Extract from track 1, time 0:30.12 to 1:10.00:
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, cdpara- noia 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 Eissfeldts (email@example.com) cdda2wav package. Cdparanoia would not have happened without it.
Joerg Schilling has also contributed SCSI expertise through his generic SCSI transport library.
