SYNOPSIS

cdda2wav [-c chans] [-s] [-m] [-b bits] [-r rate] [-a divider] [-t track[+endtrack]] [-i index] [-o offset] [-d duration] [-x] [-q] [-w] [-v optlist] [-V] [-Q] [-J] [-L cddbmode] [-R] [-P sectors] [-F] [-G] [-T] [-e] [-p percentage] [-n sectors] [-l buffers] [-N] [-J] [-H] [-g] [-B] [-D device] [-A auxdevice] [-I interface] [-O audiotype] [-C input-endianess] [-E output-endianess] [-M count] [-S speed] [-paranoia] [cddbp-server=servername] [cddbp-port=portnumber] [filename(s) or directories]  

DESCRIPTION

cdda2wav can retrieve audio tracks from CDROM drives (see README for a list of drives) that are capable of reading audio data digitally to the host (CDDA).  

OPTIONS

-D device --dev --device

uses device as the source for CDDA reading. For example /dev/cdrom for the cooked_ioctl interface and Bus,ID,Lun for the generic_scsi interface. The device has to correspond with the interface setting (see below). The setting of the environment variable CDDA_DEVICE is overridden by this option.

-A auxdevice --auxdevice

uses auxdevice as CDROM drive for ioctl usage.

-I interface --interface

specifies the interface for CDROM access: generic_scsi or (on Linux, and FreeBSD systems) cooked_ioctl.

-c channels --channels

uses 1 for mono, or 2 for stereo recording, or s for stereo recording with both channels swapped.

-s --stereo

sets to stereo recording.

-m --mono

sets to mono recording.

-x --max

sets maximum (CD) quality.

-b bits --bits-per-sample

sets bits per sample per channel: 8, 12 or 16.

-r rate --rate

sets rate in samples per second. Possible values are listed with the -R option.

-a divider --divider

sets rate to 44100Hz / divider. Possible values are listed with the -R option.

-R --dump-rates

shows a list of all sample rates and their dividers.

-P sectors --set-overlap

sets the initial number of overlap sectors for jitter correction.

-n sectors --sectors-per-request

reads sectors per request.

-l buffers --buffers-in-ring

uses a ring buffer with buffers total.

-t track+endtrack --track

selects the start track and optionally the end track.

-i index --index

selects the start index.

-o offset --offset

starts offset sectors behind start track (one sector equivalents 1/75 seconds).

-O audiotype --output-format

can be wav (for wav files) or aiff (for apple/sgi aiff files) or aifc (for apple/sgi aifc files) or au or sun (for sun .au PCM files) or cdr or raw (for headerless files to be used for cd writers).

-C endianess --cdrom-endianess

sets endianess of the input samples to 'little', 'big' or 'guess' to override defaults.

-E endianess --output-endianess

sets endianess of the output samples to 'little' or 'big' to override defaults.

-d duration --duration

sets recording time in seconds or frames. Frames (sectors) are indicated by a 'f' suffix (like 75f for 75 sectors). 0 sets the time for whole track.

-B --bulk --alltracks

copies each track into a seperate file.

-w --wait

waits for signal, then start recording.

-F --find-extremes

finds extrem amplitudes in samples.

-G --find-mono

finds if input samples are in mono.

-T --deemphasize

undo the effect of pre-emphasis in the input samples.

-e --echo

copies audio data to sound device e.g. /dev/dsp.

-p percentage --set-pitch

changes pitch of audio data copied to sound device.

-v itemlist --verbose-level

prints verbose information about the CD. Level is a list of comma seperated suboptions. Each suboption controls the type of information to be reported.

Suboption Description disable no information is given, warnings appear however all all information is given toc show table of contents summary show a summary of the recording parameters indices determine and display index offsets catalog retrieve and display the media catalog number MCN trackid retrieve and display all Intern. Standard Recording Codes ISRC sectors show the table of contents in start sector notation titles show the table of contents with track titles (when available)

-N --no-write

does not write to a file, it just reads (for debugging purposes).

-J --info-only

does not write to a file, it just gives information about the disc.

-L cddb mode --cddb

does a cddbp album- and track title lookup based on the cddb id. The parameter cddb mode defines how multiple entries shall be handled.

cddbp-server=servername

sets the server to be contacted for title lookups.

cddbp-port=portnumber

sets the port number to be used for title lookups.

-H --no-infofile

does not write an info file and a cddb file.

-g --gui

formats the output to be better parsable by gui frontends.

-M count --md5

enables calculation of MD-5 checksum for 'count' bytes from a beginning of a track.

-S speed --speed

sets the cdrom device to one of the selectable speeds for reading.

-q --quiet

quiet operation, no screen output.

-V --verbose-SCSI

enable SCSI command logging to the console. This is mainly used for debugging.

-Q --silent-SCSI

suppress SCSI command error reports to the console. This is mainly used for guis.

-paranoia

use the paranoia library instead of cdda2wav's routines for reading.

-h --help

display version of cdda2wav on standard output.

Defaults depend on the

Makefile and environment variable settings (currently CDDA_DEVICE ).
