20 icedax stands for InCrEdible Digital Audio eXtractor. It can retrieve
21 audio tracks (CDDA) from CDROM drives that are capable of reading audio
22 data digitally to the host (see README for a list of drives).
23
26 dev=device
27 -D device
29 -device device
31 uses device as the source for CDDA reading. For example
32 /dev/cdrom or Bus,ID,Lun. The device specification can also
33 have influence on the selection of the driver interface (eg. on
34 Linux). See the -I option for details.
35 The setting of the environment variable CDDA_DEVICE is overrid‐
37 den by this option.
38 -A auxdevice
40 -auxdevice auxdevice
42 uses auxdevice as CDROM drive for ioctl usage.
43 -I interface
45 -interface interface
47 specifies the interface for CDROM access: generic_scsi or (on
48 Linux, and FreeBSD systems) cooked_ioctl.
49 Using the cooked_ioctl is not recommended as this makes icedax
51 mainly depend on the audio extraction quality of the operating
52 system which is usually extremely bad.
53 -c channels --channels
55 uses 1 for mono, or 2 for stereo recording, or s for stereo
56 recording with both channels swapped.
57 -s --stereo
59 sets to stereo recording.
60 -m --mono
62 sets to mono recording.
63 -x --max
65 sets maximum (CD) quality.
66 -b bits --bits-per-sample
68 sets bits per sample per channel: 8, 12 or 16.
69 -r rate --rate
71 sets rate in samples per second. Possible values are listed
72 with the -R option.
73 -a divider --divider
75 sets rate to 44100Hz / divider. Possible values are listed with
76 the -R option.
77 -R --dump-rates
79 shows a list of all sample rates and their dividers.
80 -P sectors --set-overlap
82 sets the initial number of overlap sectors for jitter correc‐
83 tion.
84 -n sectors --sectors-per-request
86 reads sectors per request.
87 -l buffers --buffers-in-ring
89 uses a ring buffer with buffers total.
90 -t track+endtrack --track
92 selects the start track and optionally the end track.
93 -i index --index
95 selects the start index.
96 -o offset --offset
98 starts offset sectors behind start track (one sector equivalents
99 1/75 seconds).
100 -O audiotype --output-format
102 can be wav (for wav files) or aiff (for apple/sgi aiff files) or
103 aifc (for apple/sgi aifc files) or au or sun (for sun .au PCM
104 files) or cdr or raw (for headerless files to be used for cd
105 writers).
106 -C endianess --cdrom-endianess
108 sets endianess of the input samples to 'little', 'big' or
109 'guess' to override defaults.
110 -E endianess --output-endianess
112 sets endianess of the output samples to 'little' or 'big' to
113 override defaults.
114 -d duration --duration
116 sets recording time in seconds or frames. Frames (sectors) are
117 indicated by a 'f' suffix (like 75f for 75 sectors). 0 sets the
118 time for whole track.
119 -B --bulk --alltracks
121 copies each track into a separate file.
122 -w --wait
124 waits for signal, then start recording.
125 -F --find-extremes
127 finds extreme amplitudes in samples.
128 -G --find-mono
130 finds if input samples are in mono.
131 -T --deemphasize
133 undo the effect of pre-emphasis in the input samples.
134 -e --echo
136 copies audio data to sound device e.g. /dev/dsp.
137 -p percentage --set-pitch
139 changes pitch of audio data copied to sound device.
140 -v itemlist --verbose-level
142 prints verbose information about the CD. Level is a list of
143 comma separated suboptions. Each suboption controls the type of
144 information to be reported.

200 -g --gui
202 formats the output to be better parsable by gui frontends.
203 -M count --md5
205 enables calculation of MD-5 checksum for 'count' bytes from a
206 beginning of a track.
207 -S speed --speed
209 sets the cdrom device to one of the selectable speeds for read‐
210 ing.
211 -q --quiet
213 quiet operation, no screen output.
214 -V --verbose-SCSI
216 enable SCSI command logging to the console. This is mainly used
217 for debugging.
218 -Q --silent-SCSI
220 suppress SCSI command error reports to the console. This is
221 mainly used for guis.
222 -scanbus
224 Scan all SCSI devices on all SCSI busses and print the inquiry
225 strings. This option may be used to find SCSI address of the
226 CD/DVD-Recorder on a system. The numbers printed out as labels
227 are computed by: bus * 100 + target
228 --devices
230 Like -scanbus but works in a more native way, respecting the
231 device name specification on the current operating system. See
232 wodim(1) for details.
233 -paranoia
235 use the paranoia library instead of icedax's routines for read‐
236 ing.
237 -h --help
239 display version of icedax on standard output.
240 Defaults depend on the
242 Makefile and environment variable settings (currently
243 CDDA_DEVICE ).
244
246 CDDA_DEVICE is used to set the device name. The device naming is com‐
247 patible with the one used by the wodim tool.
248 CDDBP_SERVER
250 is used for cddbp title lookups when supplied.
251 CDDBP_PORT
253 is used for cddbp title lookups when supplied.
254 RSH If the RSH environment variable is present, the remote connec‐
256 tion will not be created via rcmd(3) but by calling the program
257 pointed to by RSH. Use e.g. RSH=/usr/bin/ssh to create a
258 secure shell connection.
259 Note that this forces icedax to create a pipe to the rsh(1) pro‐
261 gram and disallows icedax to directly access the network socket
262 to the remote server. This makes it impossible to set up per‐
263 formance parameters and slows down the connection compared to a
264 root initiated rcmd(3) connection.
265 RSCSI If the RSCSI environment variable is present, the remote SCSI
267 server will not be the program /opt/schily/sbin/rscsi but the
268 program pointed to by RSCSI. Note that the remote SCSI server
269 program name will be ignored if you log in using an account that
270 has been created with a remote SCSI server program as login
271 shell.

323 icedax is able to read parts of an audio CD or multimedia CDROM (con‐
324 taining audio parts) directly digitally. These parts can be written to
325 a file, a pipe, or to a sound device.
326 icedax stands for CDDA to WAV (where CDDA stands for compact disc digi‐
328 tal audio and WAV is a sound sample format introduced by MS Windows).
329 It allows copying CDDA audio data from the CDROM drive into a file in
330 WAV or other formats.
331 The latest versions try to get higher real-time scheduling priorities
333 to ensure smooth (uninterrupted) operation. These priorities are avail‐
334 able for super users and are higher than those of 'normal' processes.
335 Thus delays are minimized.
336 If your CDROM is on device DEV and it is loaded with an audio CD, you
338 may simply invoke icedax dev=DEV and it will create the sound file
339 audio.wav recording the whole track beginning with track 1 in stereo at
340 16 bit at 44100 Hz sample rate, if your file system has enough space
341 free. Otherwise recording time will be limited. For details see files
342 README and README.INSTALL
343
345 Options
346 Most of the options are used to control the format of the WAV
347 file. In the following text all of them are described.
348 Select Device
350 -D device selects the CDROM drive device to be used. The speci‐
351 fier given should correspond to the selected interface (see
352 below). CHANGE! For the cooked_ioctl interface this is the
353 cdrom device descriptor as before. The SCSI devices used with
354 the generic SCSI interface however are now addressed with their
355 SCSI-Bus, SCSI-Id, and SCSI-Lun instead of the generic SCSI
356 device descriptor!!! One example for a SCSI CDROM drive on bus
357 0 with SCSI ID 3 and lun 0 is -D0,3,0.
358 Select Auxiliary device
360 -A auxdevice is necessary for CD-Extra handling. For Non-SCSI-
361 CDROM drives this is the same device as given by -D (see above).
362 For SCSI-CDROM drives it is the CDROM drive (SCSI) device (i.e.
363 /dev/sr0 ) corresponding to the SCSI device (i.e. 0,3,0 ). It
364 has to match the device used for sampling.
365 Select Interface
367 -I interface selects the CDROM drive interface. For SCSI drives
368 use generic_scsi (cooked_ioctl may not yet be available for all
369 devices): generic_scsi and cooked_ioctl. The first uses the
370 generic SCSI interface, the latter uses the ioctl of the CDROM
371 driver. The latter variant works only when the kernel driver
372 supports CDDA reading. This entry has to match the selected
373 CDROM device (see above).
374 Enable echo to soundcard
376 -e copies audio data to the sound card while recording, so you
377 hear it nearly simultaneously. The soundcard gets the same data
378 that is recorded. This is time critical, so it works best with
379 the -q option. To use icedax as a pseudo CD player without
380 recording in a file you could use icedax -q -e -t2 -d0 -N to
381 play the whole second track. This feature reduces the recording
382 speed to at most onefold speed. You cannot make better record‐
383 ings than your sound card can play (since the same data is
384 used).
385 Change pitch of echoed audio
387 -p percentage changes the pitch of all audio echoed to a sound
388 card. Only the copy to the soundcard is affected, the recorded
389 audio samples in a file remain the same. Normal pitch, which is
390 the default, is given by 100%. Lower percentages correspond to
391 lower pitches, i.e. -p 50 transposes the audio output one
392 octave lower. See also the script pitchplay as an example. This
393 option was contributed by Raul Sobon.
394 Select mono or stereo recording
396 -m or -c 1 selects mono recording (both stereo channels are
397 mixed), -s or -c 2 or -c s selects stereo recording. Parameter s
398 will swap both sound channels.
399 Select maximum quality
401 -x will set stereo, 16 bits per sample at 44.1 KHz (full CD
402 quality). Note that other format options given later can change
403 this setting.
404 Select sample quality
406 -b 8 specifies 8 bit (1 Byte) for each sample in each channel;
407 -b 12 specifies 12 bit (2 Byte) for each sample in each channel;
408 -b 16 specifies 16 bit (2 Byte) for each sample in each channel
409 (Ensure that your sample player or sound card is capable of
410 playing 12-bit or 16-bit samples). Selecting 12 or 16 bits dou‐
411 bles file size. 12-bit samples are aligned to 16-bit samples,
412 so they waste some disk space.
413 Select sample rate
415 -r samplerate selects a sample rate. samplerate can be in a
416 range between 44100 and 900. Option -R lists all available
417 rates.
418 Select sample rate divider
420 -a divider selects a sample rate divider. divider can be mini‐
421 mally 1 and maximally 50.5 and everything between in steps of
422 0.5. Option -R lists all available rates.
423 To make the sound smoother at lower sampling rates, icedax sums
425 over n samples (where n is the specific dividend). So for 22050
426 Hertz output we have to sum over 2 samples, for 900 Hertz we
427 have to sum over 49 samples. This cancels higher frequencies.
428 Standard sector size of an audio CD (ignoring additional infor‐
429 mation) is 2352 Bytes. In order to finish summing for an output
430 sample at sector boundaries the rates above have to be chosen.
431 Arbitrary sampling rates in high quality would require some
432 interpolation scheme, which needs much more sophisticated pro‐
433 gramming.
434 List a table of all sampling rates
436 -R shows a list of all sample rates and their dividers. Dividers
437 can range from 1 to 50.5 in steps of 0.5.
438 Select start track and optionally end track
440 -t n+m selects n as the start track and optionally m as the last
441 track of a range to be recorded. These tracks must be from the
442 table of contents. This sets the track where recording begins.
443 Recording can advance through the following tracks as well (lim‐
444 ited by the optional end track or otherwise depending on record‐
445 ing time). Whether one file or different files are then created
446 depends on the -B option (see below).
447 Select start index
449 -i n selects the index to start recording with. Indices other
450 than 1 will invoke the index scanner, which will take some time
451 to find the correct start position. An offset may be given addi‐
452 tionally (see below).
453 Set recording time
455 -d n sets recording time to n seconds or set recording time for
456 whole track if n is zero. In order to specify the duration in
457 frames (sectors) also, the argument can have an appended 'f'.
458 Then the numerical argument is to be taken as frames (sectors)
459 rather than seconds. Please note that if track ranges are being
460 used they define the recording time as well thus overriding any
461 -d option specified times.
462 Recording time is defined as the time the generated sample will
464 play (at the defined sample rate). Since it's related to the
465 amount of generated samples, it's not the time of the sampling
466 process itself (which can be less or more). It's neither
467 strictly coupled with the time information on the audio CD
468 (shown by your hifi CD player). Differences can occur by the
469 usage of the -o option (see below). Notice that recording time
470 will be shortened, unless enough disk space exists. Recording
471 can be aborted at anytime by pressing the break character (sig‐
472 nal SIGQUIT).
473 .IP "Record all tracks of a complete audio CD in separate
474 files" -B copies each track into a separate file. A base name
475 can be given. File names have an appended track number and an
476 extension corresponding to the audio format. To record all audio
477 tracks of a CD, use a sufficient high duration (i.e. -d99999).
478 Set start sector offset
480 -o sectors increments start sector of the track by sectors. By
481 this option you are able to skip a certain amount at the begin‐
482 ning of a track so you can pick exactly the part you want. Each
483 sector runs for 1/75 seconds, so you have very fine control. If
484 your offset is so high that it would not fit into the current
485 track, a warning message is issued and the offset is ignored.
486 Recording time is not reduced. (To skip introductory quiet pas‐
487 sages automagically, use the -w option see below.)
488 Wait for signal option
490 -w Turning on this option will suppress all silent output at
491 startup, reducing possibly file size. icedax will watch for any
492 signal in the output signal and switches on writing to file.
493 Find extreme samples
495 -F Turning on this option will display the most negative and the
496 most positive sample value found during recording for both chan‐
497 nels. This can be useful for readjusting the volume. The values
498 shown are not reset at track boundaries, they cover the complete
499 sampling process. They are taken from the original samples and
500 have the same format (i.e. they are independent of the selected
501 output format).
502 Find if input samples are in mono
504 -G If this option is given, input samples for both channels will
505 be compared. At the end of the program the result is printed.
506 Differences in the channels indicate stereo, otherwise when both
507 channels are equal it will indicate mono.
508 Undo the pre-emphasis in the input samples
510 -T Some older audio CDs are recorded with a modified frequency
511 response called pre-emphasis. This is found mostly in classical
512 recordings. The correction can be seen in the flags of the Table
513 Of Contents often. But there are recordings, that show this set‐
514 ting only in the subchannels. If this option is given, the index
515 scanner will be started, which reads the q-subchannel of each
516 track. If pre-emphasis is indicated in the q-subchannel of a
517 track, but not in the TOC, pre-emphasis will be assumed to be
518 present, and subsequently a reverse filtering is done for this
519 track before the samples are written into the audio file.
520 Set audio format
522 -O audiotype can be wav (for wav files) or au or sun (for sun
523 PCM files) or cdr or raw (for headerless files to be used for cd
524 writers). All file samples are coded in linear pulse code modu‐
525 lation (as done in the audio compact disc format). This holds
526 for all audio formats. Wav files are compatible to Wind*ws
527 sound files, they have lsb,msb byte order as being used on the
528 audio cd. The default filename extension is '.wav'. Sun type
529 files are not like the older common logarithmically coded .au
530 files, but instead as mentioned above linear PCM is used. The
531 byte order is msb,lsb to be compatible. The default filename
532 extension is '.au'. The AIFF and the newer variant AIFC from
533 the Apple/SGI world store their samples in bigendian format
534 (msb,lsb). In AIFC no compression is used. Finally the easiest
535 'format', the cdr aka raw format. It is done per default in
536 msb,lsb byte order to satisfy the order wanted by most cd writ‐
537 ers. Since there is no header information in this format, the
538 sample parameters can only be identified by playing the samples
539 on a soundcard or similar. The default filename extension is
540 '.cdr' or '.raw'.
541 Select cdrom drive reading speed
543 -S speed allows to switch the cdrom drive to a certain level of
544 speed in order to reduce read errors. The argument is transfered
545 verbatim to the drive. Details depend very much on the cdrom
546 drives. An argument of 0 for example is often the default speed
547 of the drive, a value of 1 often selects single speed.
548 Enable MD5 checksums
550 -M count enables calculation of MD-5 checksum for 'count' bytes
551 from the beginning of a track. This was introduced for quick
552 comparisons of tracks.
553 Use Monty's libparanoia for reading of sectors
555 -paranoia selects an alternate way of extracting audio sectors.
556 Monty's library is used with the following default options:
557 PARANOIA_MODE_FULL, but without PARANOIA_MODE_NEVERSKIP
559 for details see Monty's libparanoia documentation. In this case
561 the option -P has no effect.
562 Do linear or overlapping reading of sectors
564 (This applies unless option -paranoia is used.) -P sectors
565 sets the given number of sectors for initial overlap sampling
566 for jitter correction. Two cases are to be distinguished. For
567 nonzero values, some sectors are read twice to enable icedax's
568 jitter correction. If an argument of zero is given, no overlap
569 sampling will be used. For nonzero overlap sectors icedax
570 dynamically adjusts the setting during sampling (like cdparanoia
571 does). If no match can be found, icedax retries the read with
572 an increased overlap. If the amount of jitter is lower than the
573 current overlapped samples, icedax reduces the overlap setting,
574 resulting in a higher reading speed. The argument given has to
575 be lower than the total number of sectors per request (see
576 option -n below). Icedax will check this setting and issues a
577 error message otherwise. The case of zero sectors is nice on
578 low load situations or errorfree (perfect) cdrom drives and per‐
579 fect (not scratched) audio cds.
580 Set the transfer size
582 -n sectors will set the transfer size to the specified sectors
583 per request.
584 Set number of ring buffer elements
586 -l buffers will allocate the specified number of ring buffer
587 elements.
588 Set endianess of input samples
590 -C endianess will override the default settings of the input
591 format. Endianess can be set explicitly to "little" or "big" or
592 to the automatic endianess detection based on voting with
593 "guess".
594 Set endianess of output samples
596 -E endianess (endianess can be "little" or "big") will override
597 the default settings of the output format.
598 Verbose option
600 -v itemlist prints more information. A list allows selection of
601 different information items.
602 disable keeps quiet
604 toc displays the table of contents
606 summary displays a summary of recording parameters
608 indices invokes the index scanner and displays start positions
610 of indices
611 catalog retrieves and displays a media catalog number
613 trackid retrieves and displays international standard recording
615 codes
616 sectors displays track start positions in absolute sector nota‐
618 tion
619 To combine several requests just list the suboptions separated
621 with commas.
622 The table of contents
624 The display will show the table of contents with number of
625 tracks and total time (displayed in mm:ss.hh format, mm=minutes,
626 ss=seconds, hh=rounded 1/100 seconds). The following list dis‐
627 plays track number and track time for each entry. The summary
628 gives a line per track describing the type of the track.
629 track preemphasis copypermitted tracktype chans
631 The track column holds the track number. preemphasis shows if
633 that track has been given a non linear frequency response.
634 NOTE: You can undo this effect with the -T option. copy-permit‐
635 ted indicates if this track is allowed to copy. tracktype can
636 be data or audio. On multimedia CDs (except hidden track CDs)
637 both of them should be present. channels is defined for audio
638 tracks only. There can be two or four channels.
639 No file output
641 -N this debugging option switches off writing to a file.
642 No infofile generation
644 -H this option switches off creation of an info file and a cddb
645 file.
646 Generation of simple output for gui frontends
648 -g this option switches on simple line formatting, which is
649 needed to support gui frontends (like xcd-roast).
650 Verbose SCSI logging
652 -V this option switches on logging of SCSI commands. This will
653 produce a lot of output (when SCSI devices are being used).
654 This is needed for debugging purposes. The format is the same as
655 being used with the cdrecord program from Joerg Schilling or the
656 wodim tool. See there for details.
657 Quiet option
659 -q suppresses all screen output except error messages. That
660 reduces cpu time resources.
661 Just show information option
663 -J does not write a file, it only prints information about the
664 disc (depending on the -v option). This is just for information
665 purposes.
666
668 Lookup album and track titles option
669 -L cddbp mode Icedax tries to retrieve performer, album-, and
670 track titles from a cddbp server. The default server right now
671 is 'freedb.freedb.org'. It is planned to have more control over
672 the server handling later. The parameter defines how multiple
673 entries are handled:
674 0 interactive mode, the user chooses one of the entries.
676 1 take the first entry without asking.
678 Set server for title lookups
680 cddbp-server servername When using -L or --cddb, the server
681 being contacted can be set with this option.
682 Set portnumber for title lookups
684 cddbp-port portnumber When using -L or --cddb, the server port
685 being contacted can be set with this option.
686
688 Don't create samples you cannot read. First check your sample player
689 software and sound card hardware. I experienced problems with very low
690 sample rates (stereo <= 1575 Hz, mono <= 3675 Hz) when trying to play
691 them with standard WAV players for sound blaster (maybe they are not
692 legal in WAV format). Most CD-Writers insist on audio samples in a
693 bigendian format. Now icedax supports the -E endianess option to con‐
694 trol the endianess of the written samples.
695 If your hardware is fast enough to run icedax uninterrupted and your CD
697 drive is one of the 'perfect' ones, you will gain speed when switching
698 all overlap sampling off with the -P 0 option. Further fine tuning can
699 be done with the -n sectors option. You can specify how much sectors
700 should be requested in one go.
701 Icedax supports pipes now. Use a filename of - to let icedax output its
703 samples to standard output.
704 Conversion to other sound formats can be done using the sox program
706 package (although the use of sox -x to change the byte order of samples
707 should be no more necessary; see option -E to change the output byte‐
708 order).
709 If you want to sample more than one track into different files in one
711 run, this is currently possible with the -B option. When recording time
712 exceeds the track limit a new file will be opened for the next track.
713
715 Icedax can generate a lot of files for various purposes.
716 Audio files:
718 There are audio files containing samples with default extensions These
720 files are not generated when option (-N) is given. Multiple files may
721 be written when the bulk copy option (-B) is used. Individual file
722 names can be given as arguments. If the number of file names given is
723 sufficient to cover all included audio tracks, the file names will be
724 used verbatim. Otherwise, if there are less file names than files
725 needed to write the included tracks, the part of the file name before
726 the extension is extended with '_dd' where dd represents the current
727 track number.
728 Cddb and Cdindex files:
730 If icedax detects cd-extra or cd-text (album/track) title information,
732 then .cddb and .cdindex files are generated unless suppressed by the
733 option -H. They contain suitable formatted entries for submission to
734 audio cd track title databases in the internet. The CDINDEX and
735 CDDB(tm) systems are currently supported. For more information please
736 visit www.musicbrainz.org and www.freedb.com.
737 Inf files:
739 The inf files are describing the sample files and the part from the
741 audio cd, it was taken from. They are a means to transfer information
742 to a cd burning program like wodim. For example, if the original audio
743 cd had pre-emphasis enabled, and icedax -T did remove the pre-emphasis,
744 then the inf file has pre-emphasis not set (since the audio file does
745 not have it anymore), while the .cddb and the .cdindex have pre-empha‐
746 sis set as the original does.
747
749 IMPORTANT: it is prohibited to sell copies of copyrighted material by
750 noncopyright holders. This program may not be used to circumvent copy‐
751 rights. The user acknowledges this constraint when using the software.
752
754 Generation of md5 checksums is currently broken.
755 Performance may not be optimal on slower systems.
757 The index scanner may give timeouts.
759 The resampling (rate conversion code) uses polynomial interpolation,
761 which is not optimal.
762 Icedax should use threads.
764 Icedax currently cannot sample hidden audio tracks (track 1 index 0).

769 fuer integrierte Schaltungen (FhG-IIS) (http://www.iis.fhg.de/) for
770 financial support. Plextor Europe and Ricoh Japan provided cdrom disk
771 drives and cd burners which helped a lot to develop this software.
772 Rammi has helped a lot with the debugging and showed a lot of stamina
773 when hearing 100 times the first 16 seconds of the first track of the
774 Krupps CD. Libparanoia contributed by Monty (Christopher Montgomery)

779 This manpage describes the program implementation of icedax as shipped
781 by the cdrkit distribution. See http://alioth.debian.org/projects/deb‐
782 burn/ for details. It is a spinoff from the original program cdda2wav
783 as distributed in the cdrtools package [1]. However, the cdrtools
784 developers are not involved in the development of this spinoff and
785 therefore shall not be made responsible for any problem caused by it.
786 Do not try to get support for this program by contacting the original
787 authors.
788 If you have support questions, send them to
790 debburn-devel@lists.alioth.debian.org
792 If you have definitely found a bug, send a mail to this list or to
794 submit@bugs.debian.org
