cd-paranoia 9.8 (Paranoia release III via libcdio) - an audio CD reading utility which
includes extra data verification features
cd-paranoia [options] span [outfile]
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.
Be absurdly verbose about the autosensing and reading process. Good for setup and
Do not print any progress or error information during the reading process.
Force output of progress information to stderr (for wrapper scripts).
Print the program version and quit.
Perform CD-ROM drive autosense, query and print the CD-ROM table of contents, then
Forces a complete search for a cdrom drive, even if the /dev/cdrom link exists.
Print a brief synopsis of cd-paranoia usage and options.
-l --log-summary file
Save result summary to file.
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.
Output headerless data as raw 16 bit PCM data with interleaved samples in LSB first
Output headerless data as raw 16 bit PCM data with interleaved samples in MSB first
Output data in Micro$oft RIFF WAV format (note that WAV data is always LSB first
Output data in Apple AIFF format (note that AIFC data is always in MSB first byte
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; cd-paranoia will split the output into multiple
files at track boundaries. Output file names are prepended with 'track#.'
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.
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...
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.
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.
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.
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
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.

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:
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 sectors (75 sectors per
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,
Specifies ripping from track 1, second 20, sector 35 to the end of track 1.
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
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.
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:
cd-paranoia -- "-3"
The "--" above is to distinguish "-3" from an option flag.
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.
