DESCRIPTION
icedax stands for InCrEdible Digital Audio eXtractor. It can retrieve
audio tracks (CDDA) from CDROM drives that are capable of reading audio
data digitally to the host (see README for a list of drives).
OPTIONS
dev=device
-D device
-device device
uses device as the source for CDDA reading. For example
/dev/cdrom or Bus,ID,Lun. The device specification can also
have influence on the selection of the driver interface (eg. on
Linux). See the -I option for details.
The setting of the environment variable CDDA_DEVICE is overrid-
den by this option.
-A auxdevice
-auxdevice auxdevice
uses auxdevice as CDROM drive for ioctl usage.
-I interface
-interface interface
specifies the interface for CDROM access: generic_scsi or (on
Linux, and FreeBSD systems) cooked_ioctl.
Using the cooked_ioctl is not recommended as this makes icedax
mainly depend on the audio extraction quality of the operating
system which is usually extremely bad.
-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 correc-
tion.
-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 separate file.
-w --wait
waits for signal, then start recording.
-F --find-extremes
finds extreme 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 separated suboptions. Each suboption controls the type of
information to be reported.

poses).
-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.
+----------+------------------------------------------+
|Parameter | Description |
+----------+------------------------------------------+
| 0 | interactive mode. The user selects the |
| | entry to use. |
+----------+------------------------------------------+
| 1 | first fit mode. The first entry is taken |
| | unconditionally. |
+----------+------------------------------------------+
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 read-
ing.
-q --quiet

for debugging.
-Q --silent-SCSI
suppress SCSI command error reports to the console. This is
mainly used for guis.
-scanbus
Scan all SCSI devices on all SCSI busses and print the inquiry
strings. This option may be used to find SCSI address of the
CD/DVD-Recorder on a system. The numbers printed out as labels
are computed by: bus * 100 + target
--devices
Like -scanbus but works in a more native way, respecting the
device name specification on the current operating system. See
wodim(1) for details.
-paranoia
use the paranoia library instead of icedax's routines for read-
ing.
-h --help
display version of icedax on standard output.
Defaults depend on the
Makefile and environment variable settings (currently
CDDA_DEVICE ).
ENVIRONMENT VARIABLES
CDDA_DEVICE is used to set the device name. The device naming is com-
patible with the one used by the wodim tool.
CDDBP_SERVER
is used for cddbp title lookups when supplied.
CDDBP_PORT
is used for cddbp title lookups when supplied.
RSH If the RSH environment variable is present, the remote connec-
tion will not be created via rcmd(3) but by calling the program
pointed to by RSH. Use e.g. RSH=/usr/bin/ssh to create a
secure shell connection.
Note that this forces icedax to create a pipe to the rsh(1) pro-
gram and disallows icedax to directly access the network socket
to the remote server. This makes it impossible to set up per-
formance parameters and slows down the connection compared to a
root initiated rcmd(3) connection.
RSCSI If the RSCSI environment variable is present, the remote SCSI
server will not be the program /opt/schily/sbin/rscsi but the
program pointed to by RSCSI. Note that the remote SCSI server
program name will be ignored if you log in using an account that
has been created with a remote SCSI server program as login
shell.
RETURN VALUES
icedax uses the following exit codes to indicate various degrees of
success:
+---------+-----------------------------------------------------------+
|Exitcode | Description |
+---------+-----------------------------------------------------------+
| 0 | no errors encountered, successful operation. |
+---------+-----------------------------------------------------------+

DISCUSSION
icedax is able to read parts of an audio CD or multimedia CDROM (con-
taining audio parts) directly digitally. These parts can be written to
a file, a pipe, or to a sound device.
icedax stands for CDDA to WAV (where CDDA stands for compact disc digi-
tal audio and WAV is a sound sample format introduced by MS Windows).
It allows copying CDDA audio data from the CDROM drive into a file in
WAV or other formats.
The latest versions try to get higher real-time scheduling priorities
to ensure smooth (uninterrupted) operation. These priorities are avail-
able for super users and are higher than those of 'normal' processes.
Thus delays are minimized.
If your CDROM is on device DEV and it is loaded with an audio CD, you
may simply invoke icedax dev=DEV and it will create the sound file
audio.wav recording the whole track beginning with track 1 in stereo at
16 bit at 44100 Hz sample rate, if your file system has enough space
free. Otherwise recording time will be limited. For details see files
README and README.INSTALL
HINTS ON OPTIONS
Options
Most of the options are used to control the format of the WAV
file. In the following text all of them are described.
Select Device
-D device selects the CDROM drive device to be used. The speci-
fier given should correspond to the selected interface (see
below). CHANGE! For the cooked_ioctl interface this is the
cdrom device descriptor as before. The SCSI devices used with
the generic SCSI interface however are now addressed with their
SCSI-Bus, SCSI-Id, and SCSI-Lun instead of the generic SCSI
device descriptor!!! One example for a SCSI CDROM drive on bus
0 with SCSI ID 3 and lun 0 is -D0,3,0.
Select Auxiliary device
-A auxdevice is necessary for CD-Extra handling. For Non-SCSI-
CDROM drives this is the same device as given by -D (see above).
For SCSI-CDROM drives it is the CDROM drive (SCSI) device (i.e.
/dev/sr0 ) corresponding to the SCSI device (i.e. 0,3,0 ). It
has to match the device used for sampling.
Select Interface
-I interface selects the CDROM drive interface. For SCSI drives
use generic_scsi (cooked_ioctl may not yet be available for all
devices): generic_scsi and cooked_ioctl. The first uses the
generic SCSI interface, the latter uses the ioctl of the CDROM
driver. The latter variant works only when the kernel driver
supports CDDA reading. This entry has to match the selected
CDROM device (see above).
Enable echo to soundcard
-e copies audio data to the sound card while recording, so you
hear it nearly simultaneously. The soundcard gets the same data
that is recorded. This is time critical, so it works best with
the -q option. To use icedax as a pseudo CD player without
recording in a file you could use icedax -q -e -t2 -d0 -N to
play the whole second track. This feature reduces the recording
speed to at most onefold speed. You cannot make better record-
ings than your sound card can play (since the same data is
used).
Change pitch of echoed audio
-p percentage changes the pitch of all audio echoed to a sound
card. Only the copy to the soundcard is affected, the recorded
audio samples in a file remain the same. Normal pitch, which is
the default, is given by 100%. Lower percentages correspond to
lower pitches, i.e. -p 50 transposes the audio output one
octave lower. See also the script pitchplay as an example. This
option was contributed by Raul Sobon.
Select mono or stereo recording
-m or -c 1 selects mono recording (both stereo channels are
mixed), -s or -c 2 or -c s selects stereo recording. Parameter s
will swap both sound channels.
Select maximum quality
-x will set stereo, 16 bits per sample at 44.1 KHz (full CD
quality). Note that other format options given later can change
this setting.
Select sample quality
-b 8 specifies 8 bit (1 Byte) for each sample in each channel;
-b 12 specifies 12 bit (2 Byte) for each sample in each channel;
-b 16 specifies 16 bit (2 Byte) for each sample in each channel
(Ensure that your sample player or sound card is capable of
playing 12-bit or 16-bit samples). Selecting 12 or 16 bits dou-
bles file size. 12-bit samples are aligned to 16-bit samples,
so they waste some disk space.
Select sample rate
-r samplerate selects a sample rate. samplerate can be in a
range between 44100 and 900. Option -R lists all available
rates.
Select sample rate divider
-a divider selects a sample rate divider. divider can be mini-
mally 1 and maximally 50.5 and everything between in steps of
0.5. Option -R lists all available rates.
To make the sound smoother at lower sampling rates, icedax sums
over n samples (where n is the specific dividend). So for 22050
Hertz output we have to sum over 2 samples, for 900 Hertz we
have to sum over 49 samples. This cancels higher frequencies.
Standard sector size of an audio CD (ignoring additional infor-
mation) is 2352 Bytes. In order to finish summing for an output
sample at sector boundaries the rates above have to be chosen.
Arbitrary sampling rates in high quality would require some
interpolation scheme, which needs much more sophisticated pro-
gramming.
List a table of all sampling rates
-R shows a list of all sample rates and their dividers. Dividers
can range from 1 to 50.5 in steps of 0.5.
Select start track and optionally end track
-t n+m selects n as the start track and optionally m as the last
track of a range to be recorded. These tracks must be from the
table of contents. This sets the track where recording begins.
Recording can advance through the following tracks as well (lim-
ited by the optional end track or otherwise depending on record-
ing time). Whether one file or different files are then created
depends on the -B option (see below).
Select start index
-i n selects the index to start recording with. Indices other
than 1 will invoke the index scanner, which will take some time
to find the correct start position. An offset may be given addi-
tionally (see below).
Set recording time
-d n sets recording time to n seconds or set recording time for
whole track if n is zero. In order to specify the duration in
frames (sectors) also, the argument can have an appended 'f'.
Then the numerical argument is to be taken as frames (sectors)
rather than seconds. Please note that if track ranges are being
used they define the recording time as well thus overriding any
-d option specified times.
Recording time is defined as the time the generated sample will
play (at the defined sample rate). Since it's related to the
amount of generated samples, it's not the time of the sampling
process itself (which can be less or more). It's neither
strictly coupled with the time information on the audio CD
(shown by your hifi CD player). Differences can occur by the
usage of the -o option (see below). Notice that recording time
will be shortened, unless enough disk space exists. Recording
can be aborted at anytime by pressing the break character (sig-
nal SIGQUIT).
.IP "Record all tracks of a complete audio CD in separate
files" -B copies each track into a separate file. A base name
can be given. File names have an appended track number and an
extension corresponding to the audio format. To record all audio
tracks of a CD, use a sufficient high duration (i.e. -d99999).
Set start sector offset
-o sectors increments start sector of the track by sectors. By
this option you are able to skip a certain amount at the begin-
ning of a track so you can pick exactly the part you want. Each
sector runs for 1/75 seconds, so you have very fine control. If
your offset is so high that it would not fit into the current
track, a warning message is issued and the offset is ignored.
Recording time is not reduced. (To skip introductory quiet pas-
sages automagically, use the -w option see below.)
Wait for signal option
-w Turning on this option will suppress all silent output at
startup, reducing possibly file size. icedax will watch for any
signal in the output signal and switches on writing to file.
Find extreme samples
-F Turning on this option will display the most negative and the
most positive sample value found during recording for both chan-
nels. This can be useful for readjusting the volume. The values
shown are not reset at track boundaries, they cover the complete
sampling process. They are taken from the original samples and
have the same format (i.e. they are independent of the selected
output format).
Find if input samples are in mono
-G If this option is given, input samples for both channels will
be compared. At the end of the program the result is printed.
Differences in the channels indicate stereo, otherwise when both
channels are equal it will indicate mono.
Undo the pre-emphasis in the input samples
-T Some older audio CDs are recorded with a modified frequency
response called pre-emphasis. This is found mostly in classical
recordings. The correction can be seen in the flags of the Table
Of Contents often. But there are recordings, that show this set-
ting only in the subchannels. If this option is given, the index
scanner will be started, which reads the q-subchannel of each
track. If pre-emphasis is indicated in the q-subchannel of a
track, but not in the TOC, pre-emphasis will be assumed to be
present, and subsequently a reverse filtering is done for this
track before the samples are written into the audio file.
Set audio format
-O audiotype can be wav (for wav files) or au or sun (for sun
PCM files) or cdr or raw (for headerless files to be used for cd
writers). All file samples are coded in linear pulse code modu-
lation (as done in the audio compact disc format). This holds
for all audio formats. Wav files are compatible to Wind*ws
sound files, they have lsb,msb byte order as being used on the
audio cd. The default filename extension is '.wav'. Sun type
files are not like the older common logarithmically coded .au
files, but instead as mentioned above linear PCM is used. The
byte order is msb,lsb to be compatible. The default filename
extension is '.au'. The AIFF and the newer variant AIFC from
the Apple/SGI world store their samples in bigendian format
(msb,lsb). In AIFC no compression is used. Finally the easiest
'format', the cdr aka raw format. It is done per default in
msb,lsb byte order to satisfy the order wanted by most cd writ-
ers. Since there is no header information in this format, the
sample parameters can only be identified by playing the samples
on a soundcard or similar. The default filename extension is
'.cdr' or '.raw'.
Select cdrom drive reading speed
-S speed allows to switch the cdrom drive to a certain level of
speed in order to reduce read errors. The argument is transfered
verbatim to the drive. Details depend very much on the cdrom
drives. An argument of 0 for example is often the default speed
of the drive, a value of 1 often selects single speed.
Enable MD5 checksums
-M count enables calculation of MD-5 checksum for 'count' bytes
from the beginning of a track. This was introduced for quick
comparisons of tracks.
Use Monty's libparanoia for reading of sectors
-paranoia selects an alternate way of extracting audio sectors.
Monty's library is used with the following default options:
PARANOIA_MODE_FULL, but without PARANOIA_MODE_NEVERSKIP
for details see Monty's libparanoia documentation. In this case
the option -P has no effect.
Do linear or overlapping reading of sectors
(This applies unless option -paranoia is used.) -P sectors
sets the given number of sectors for initial overlap sampling
for jitter correction. Two cases are to be distinguished. For
nonzero values, some sectors are read twice to enable icedax's
jitter correction. If an argument of zero is given, no overlap
sampling will be used. For nonzero overlap sectors icedax
dynamically adjusts the setting during sampling (like cdparanoia
does). If no match can be found, icedax retries the read with
an increased overlap. If the amount of jitter is lower than the
current overlapped samples, icedax reduces the overlap setting,
resulting in a higher reading speed. The argument given has to
be lower than the total number of sectors per request (see
option -n below). Icedax will check this setting and issues a
error message otherwise. The case of zero sectors is nice on
low load situations or errorfree (perfect) cdrom drives and per-
fect (not scratched) audio cds.
Set the transfer size
-n sectors will set the transfer size to the specified sectors
per request.
Set number of ring buffer elements
-l buffers will allocate the specified number of ring buffer
elements.
Set endianess of input samples
-C endianess will override the default settings of the input
format. Endianess can be set explicitly to "little" or "big" or
to the automatic endianess detection based on voting with
"guess".
Set endianess of output samples
-E endianess (endianess can be "little" or "big") will override
the default settings of the output format.
Verbose option
-v itemlist prints more information. A list allows selection of
different information items.
disable keeps quiet
toc displays the table of contents
summary displays a summary of recording parameters
indices invokes the index scanner and displays start positions
of indices
catalog retrieves and displays a media catalog number
trackid retrieves and displays international standard recording
codes
sectors displays track start positions in absolute sector nota-
tion
To combine several requests just list the suboptions separated
with commas.
The table of contents
The display will show the table of contents with number of
tracks and total time (displayed in mm:ss.hh format, mm=minutes,
ss=seconds, hh=rounded 1/100 seconds). The following list dis-
plays track number and track time for each entry. The summary
gives a line per track describing the type of the track.
track preemphasis copypermitted tracktype chans
The track column holds the track number. preemphasis shows if
that track has been given a non linear frequency response.
NOTE: You can undo this effect with the -T option. copy-permit-
ted indicates if this track is allowed to copy. tracktype can
be data or audio. On multimedia CDs (except hidden track CDs)
both of them should be present. channels is defined for audio
tracks only. There can be two or four channels.
No file output
-N this debugging option switches off writing to a file.
No infofile generation
-H this option switches off creation of an info file and a cddb
file.
Generation of simple output for gui frontends
-g this option switches on simple line formatting, which is
needed to support gui frontends (like xcd-roast).
Verbose SCSI logging
-V this option switches on logging of SCSI commands. This will
produce a lot of output (when SCSI devices are being used).
This is needed for debugging purposes. The format is the same as
being used with the cdrecord program from Joerg Schilling or the
wodim tool. See there for details.
Quiet option
-q suppresses all screen output except error messages. That
reduces cpu time resources.
Just show information option
-J does not write a file, it only prints information about the
disc (depending on the -v option). This is just for information
purposes.
CDDBP support
Lookup album and track titles option
-L cddbp mode Icedax tries to retrieve performer, album-, and
track titles from a cddbp server. The default server right now
is 'freedb.freedb.org'. It is planned to have more control over
the server handling later. The parameter defines how multiple
entries are handled:
0 interactive mode, the user chooses one of the entries.
1 take the first entry without asking.
Set server for title lookups
cddbp-server servername When using -L or --cddb, the server
being contacted can be set with this option.
Set portnumber for title lookups
cddbp-port portnumber When using -L or --cddb, the server port
being contacted can be set with this option.
HINTS ON USAGE
Don't create samples you cannot read. First check your sample player
software and sound card hardware. I experienced problems with very low
sample rates (stereo <= 1575 Hz, mono <= 3675 Hz) when trying to play
them with standard WAV players for sound blaster (maybe they are not
legal in WAV format). Most CD-Writers insist on audio samples in a
bigendian format. Now icedax supports the -E endianess option to con-
trol the endianess of the written samples.
If your hardware is fast enough to run icedax uninterrupted and your CD
drive is one of the 'perfect' ones, you will gain speed when switching
all overlap sampling off with the -P 0 option. Further fine tuning can
be done with the -n sectors option. You can specify how much sectors
should be requested in one go.
Icedax supports pipes now. Use a filename of - to let icedax output its
samples to standard output.
Conversion to other sound formats can be done using the sox program
package (although the use of sox -x to change the byte order of samples
should be no more necessary; see option -E to change the output byte-
order).
If you want to sample more than one track into different files in one
run, this is currently possible with the -B option. When recording time
exceeds the track limit a new file will be opened for the next track.
FILES
Icedax can generate a lot of files for various purposes.
Audio files:
There are audio files containing samples with default extensions .wav,
.au, .aifc, .aiff, and .cdr according to the selected sound format.
These files are not generated when option (-N) is given. Multiple files
may be written when the bulk copy option (-B) is used. Individual file
names can be given as arguments. If the number of file names given is
sufficient to cover all included audio tracks, the file names will be
used verbatim. Otherwise, if there are less file names than files
needed to write the included tracks, the part of the file name before
the extension is extended with '_dd' where dd represents the current
track number.
Cddb and Cdindex files:
If icedax detects cd-extra or cd-text (album/track) title information,
then .cddb and .cdindex files are generated unless suppressed by the
option -H. They contain suitable formatted entries for submission to
audio cd track title databases in the internet. The CDINDEX and
CDDB(tm) systems are currently supported. For more information please
visit www.musicbrainz.org and www.freedb.com.
Inf files:
The inf files are describing the sample files and the part from the
audio cd, it was taken from. They are a means to transfer information
to a cd burning program like wodim. For example, if the original audio
cd had pre-emphasis enabled, and icedax -T did remove the pre-emphasis,
then the inf file has pre-emphasis not set (since the audio file does
not have it anymore), while the .cddb and the .cdindex have pre-empha-
sis set as the original does.
WARNING
IMPORTANT: it is prohibited to sell copies of copyrighted material by
noncopyright holders. This program may not be used to circumvent copy-
rights. The user acknowledges this constraint when using the software.
BUGS
Generation of md5 checksums is currently broken.
Performance may not be optimal on slower systems.
The index scanner may give timeouts.
The resampling (rate conversion code) uses polynomial interpolation,
which is not optimal.
Icedax should use threads.
Icedax currently cannot sample hidden audio tracks (track 1 index 0).
