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

-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.

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.
