cdparanoia (Paranoia release III) - an audio CD reading utility which includes extra data
version III release alpha 9.8 (02 Mar 2001)
cdparanoia [options] span [outfile]
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 verification, synchro-
nization, error handling and scratch reconstruction capability.
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 CDROM drive autosense, query and print the CDROM table of contents, then
Forces a complete search for a cdrom drive, even if the /dev/cdrom link exists.
Print a brief synopsis of cdparanoia usage and options.
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; cdparanoia will split the output into multiple
files at track boundaries. Output file names are prepended with 'track#.'
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.
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 proprietary).
-g --force-generic-device device
This option is used along with -d when one wants explicit control in setting both
the SCSI cdrom and generic devices seperately. This option is only useful on non-
standard SCSI setups.
-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 val-
ues 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 boundaries for the whole disc manu-
ally 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 caus-
ing read errors on most drives and possibly even hard lockups on some buggy hard-
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.
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 recom-
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.

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 syn-
tax 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, respec-
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:
cdparanoia -- "-3"
The "--" above is to distinguish "-3" from an option flag.
The output file argument is optional; if it is not specified, cdparanoia will output sam-
ples 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 out-
put; all data formats may be piped.
