These parts can be +written to a file, a pipe, or to a sound device. +.PP +.B icedax +stands for +.B CDDA +to +.B WAV +(where +.B CDDA +stands for compact disc digital audio and +.B WAV +is a sound sample format introduced by MS Windows). It +allows copying +.B CDDA +audio data from the CDROM drive into a file in +.B WAV +or other formats. +.PP +The latest versions try to get higher real-time scheduling priorities to ensure +smooth (uninterrupted) operation. These priorities are available for super users +and are higher than those of 'normal' processes. Thus delays are minimized. +.PP +If your CDROM is on device +.B DEV +and it is loaded with an audio CD, you may simply invoke +.B icedax dev=DEV +and it will create the sound file +.B 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 +.B README +and +.B README.INSTALL +. +.SH "HINTS ON OPTIONS" +.IP "Options" +Most of the options are used to control the format of the WAV file. In +the following text all of them are described. +.IP "Select Device" +.BI \-D " device" +selects the CDROM drive device to be used. +The specifier given should correspond to the selected interface (see below). +.B CHANGE! +For the cooked_ioctl interface this is the cdrom device descriptor as before. +.B The SCSI devices used with the generic SCSI interface however are now +.B addressed with their SCSI-Bus, SCSI-Id, and SCSI-Lun instead of the generic +.B SCSI device descriptor!!! +One example for a SCSI CDROM drive on bus 0 with SCSI ID 3 and lun 0 is -D0,3,0. +.IP "Select Auxiliary device" +.BI \-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. +.B /dev/sr0 +) corresponding to the SCSI device (i.e. +.B 0,3,0 +). It has to match the device used for sampling. +.IP "Select Interface" +.BI \-I " interface" +selects the CDROM drive interface. For SCSI drives use generic_scsi +(cooked_ioctl may not yet be available for all devices): +.B generic_scsi +and +.BR 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 +.B CDDA +reading. This entry has to match the selected CDROM device (see above). +.IP "Enable echo to soundcard" +.B \-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 +.B \-q +option. To use +.B icedax +as a pseudo CD player without recording in a file you could use +.B "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 recordings than your sound card +can play (since the same data is used). +.IP "Change pitch of echoed audio" +.B "\-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 +.B pitchplay +as an example. This option was contributed by Raul Sobon. +.IP "Select mono or stereo recording" +.B \-m +or +.B "\-c 1" +selects mono recording (both stereo channels are mixed), +.B \-s +or +.B "\-c 2" +or +.B "\-c s" +selects stereo recording. Parameter s +will swap both sound channels. +.IP "Select maximum quality" +.B \-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. +.IP "Select sample quality" +.B "\-b 8" +specifies 8 bit (1 Byte) for each sample in each channel; +.B "\-b 12" +specifies 12 bit (2 Byte) for each sample in each channel; +.B "\-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 doubles file size. 12-bit samples are +aligned to 16-bit samples, so they waste some disk space. +.IP "Select sample rate" +.BI \-r " samplerate" +selects a sample rate. +.I samplerate +can be in a range between 44100 and 900. Option +.B \-R +lists all available rates. +.IP "Select sample rate divider" +.BI \-a " divider" +selects a sample rate divider. +.I divider +can be minimally 1 and maximally 50.5 and everything between in steps of 0.5. +Option +.B \-R +lists all available rates. +.IP +To make the sound smoother at lower sampling rates, +.B icedax +sums over +.I n +samples (where +.I 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 information) 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 programming. +.IP "List a table of all sampling rates" +.BI \-R +shows a list of all sample rates and their dividers. Dividers can range +from 1 to 50.5 in steps of 0.5. +.IP "Select start track and optionally end track" +.BI \-t " n+m" +selects +.B n +as the start track and optionally +.B 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 (limited by the optional end track or otherwise +depending on recording time). Whether one file or different files are +then created depends on the +.B \-B +option (see below). +.IP "Select start index" +.BI \-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 additionally (see below). +.IP "Set recording time" +.B \-d " n" +sets recording time to +.I n +seconds or set recording time for whole track if +.I 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 +.BR \-d " option" +specified times. +.IP +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 +.B \-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 (signal SIGQUIT). + .IP "Record all tracks of a complete audio CD in separate files" +.B \-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). +.IP "Set start sector offset" +.BI \-o " sectors" +increments start sector of the track by +.IR sectors . +By this option you are able to skip a certain amount at the beginning 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 passages automagically, use the +.B \-w +option see below.) +.IP "Wait for signal option" +.B \-w +Turning on this option will suppress all silent output at startup, +reducing possibly file size. +.B icedax +will watch for any signal in the output signal and switches on writing +to file. +.IP "Find extreme samples" +.B \-F +Turning on this option will display the most negative and the most positive +sample value found during recording for both channels. 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). +.IP "Find if input samples are in mono" +.B \-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. +.IP "Undo the pre-emphasis in the input samples" +.B \-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 setting 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. +.IP "Set audio format" +.B \-O " audiotype" +can be +.I wav +(for wav files) or +.I au +or +.I sun +(for sun PCM files) or +.I cdr +or +.I raw +(for headerless files to be used for cd writers). +All file samples are coded in linear pulse code modulation (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 writers. 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'. +.IP "Select cdrom drive reading speed" +.B \-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. +.IP "Enable MD5 checksums" +.B \-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. +.IP "Use Monty's libparanoia for reading of sectors" +.B \-paranoia +selects an alternate way of extracting audio sectors. Monty's library is used +with the following default options: +.sp +PARANOIA_MODE_FULL, but without PARANOIA_MODE_NEVERSKIP +.sp +for details see Monty's libparanoia documentation. +In this case the option +.B \-P +has no effect. +.IP "Do linear or overlapping reading of sectors" +(This applies unless option +.B \-paranoia +is used.) +.B \-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 +.I -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 perfect (not scratched) audio cds. +.IP "Set the transfer size" +.B \-n " sectors" +will set the transfer size to the specified sectors per request. +.IP "Set number of ring buffer elements" +.B \-l " buffers" +will allocate the specified number of ring buffer elements. +.IP "Set endianess of input samples" +.B \-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". +.IP "Set endianess of output samples" +.B \-E " endianess" +(endianess can be "little" or "big") will override the default settings +of the output format. +.IP "Verbose option" +.B \-v " itemlist" +prints more information. A list allows selection of different +information items. +.sp +.B "disable" +keeps quiet +.sp +.B "toc" +displays the table of contents +.sp +.B "summary" +displays a summary of recording parameters +.sp +.B "indices" +invokes the index scanner and displays start positions of indices +.sp +.B "catalog" +retrieves and displays a media catalog number +.sp +.B "trackid" +retrieves and displays international standard recording codes +.sp +.B "sectors" +displays track start positions in absolute sector notation +.sp +To combine several requests just list the suboptions separated with commas. +.IP "The table of contents" +The display will show the table of contents with number of tracks and +total time (displayed in +.IR mm : ss . hh +format, +.IR mm =minutes, +.IR ss =seconds, +.IR hh "=rounded 1/100 seconds)." +The following list displays track number and track time for each entry. +The summary gives a line per track describing the type of the track. +.sp +.ce 1 +.B "track preemphasis copypermitted tracktype chans" +.sp +The +.B track +column holds the track number. +.B preemphasis +shows if that track has been given a non linear frequency response. +NOTE: You can undo this effect with the +.B \-T +option. +.B "copy-permitted" +indicates if this track is allowed to copy. +.B "tracktype" +can be data or audio. On multimedia CDs (except hidden track CDs) +both of them should be present. +.B "channels" +is defined for audio tracks only. There can be two or four channels. +.IP "No file output" +.B \-N +this debugging option switches off writing to a file. +.IP "No infofile generation" +.B \-H +this option switches off creation of an info file and a cddb file. +.IP "Generation of simple output for gui frontends" +.B \-g +this option switches on simple line formatting, which is needed to support +gui frontends (like xcd-roast). +.IP "Verbose SCSI logging" +.B \-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 J\*org Schilling or +the wodim tool. See there for details. +.IP "Quiet option" +.B \-q +suppresses all screen output except error messages. +That reduces cpu time resources. +.IP "Just show information option" +.B \-J +does not write a file, it only prints information about the disc (depending +on the +.B \-v +option). This is just for information purposes. +.SH "CDDBP support" +.IP "Lookup album and track titles option" +.B \-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: +.PP +0 interactive mode, the user chooses one of the entries. +.PP +1 take the first entry without asking. +.IP "Set server for title lookups" +.B cddbp-server " servername" +When using \-L or --cddb, the server being contacted can be set with +this option. +.IP "Set portnumber for title lookups" +.B cddbp-port " portnumber" +When using \-L or --cddb, the server port being contacted can be set with +this option. +.SH "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 +.B WAV +format). Most CD-Writers insist on audio samples in a bigendian format. +Now icedax supports the +.B \-E " endianess" +option to control the endianess of the written samples. +.PP +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 +.B \-P " 0" +option. Further fine tuning can be done with the +.B \-n " sectors" +option. You can specify how much sectors should be requested in one go. +.PP +Icedax supports +.B pipes +now. Use a filename of +.B \- +to let icedax output its samples to standard output. +.PP +Conversion to other sound formats can be done using the +.B sox +program package (although the use of +.B sox -x +to change the byte order of samples should be no more necessary; see option +.B \-E +to change the output byteorder). +.PP +If you want to sample more than one track into +different files in one run, this is currently possible with the +.B \-B +option. When recording time exceeds the track limit a new file will +be opened for the next track. +.SH FILES +Icedax can generate a lot of files for various purposes. +.sp +Audio files: +.sp +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. +.sp +Cddb and Cdindex files: +.sp +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. +.sp +Inf files: +.sp +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-emphasis set as the original does. +.SH WARNING +.B IMPORTANT: +it is prohibited to sell copies of copyrighted material by noncopyright +holders. This program may not be used to circumvent copyrights. +The user acknowledges this constraint when using the software. +.SH BUGS +Generation of md5 checksums is currently broken. +.sp +Performance may not be optimal on slower systems. +.sp +The index scanner may give timeouts. +.sp +The resampling (rate conversion code) uses polynomial interpolation, which +is not optimal. +.sp +Icedax should use threads. +.sp +Icedax currently cannot sample hidden audio tracks (track 1 index 0). +.SH ACKNOWLEDGEMENTS +Thanks goto Project MODE (http://www.mode.net/) and Fraunhofer Institut f\*ur +integrierte Schaltungen (FhG-IIS) (http://www.iis.fhg.de/) for financial +support. +Plextor Europe and Ricoh Japan provided cdrom disk drives and cd burners +which helped a lot to develop this software. +Rammi has helped a lot with the debugging and showed a lot of stamina when +hearing 100 times the first 16 seconds of the first track of the Krupps CD. +Libparanoia contributed by Monty (Christopher Montgomery) xiphmont@mit.edu. +.SH AUTHOR +Heiko Eissfeldt heiko@colossus.escape.de +.PP +This manpage describes the program implementation of +.B +icedax +as shipped by the cdrkit distribution.
