       xmcd - CD digital audio player utility for X11/Motif

       xmcd  [toolkitoption ...] [-dev device] [-instcmap] [-remote] [-rmthost
       hostname] [-help] [-debug level#] [-c device] [-X] [-o]	[command  [arg

       Xmcd is a program that allows the use of	the CD-ROM, CD-R, CD-RW	or DVD
       drive as	a full-featured	stereo compact-disc player  and	 "ripper"  for
       the  X window system.  See cda(1) for the command-line CD player.  xmcd
       and cda uses the	same configuration and support files.

       Most of the features found on "real" CD players are available in	 xmcd,
       such  as	 shuffle  and  repeat,	track programming functions, a numeric
       keypad and track	warp  slider  for  direct  track  access.   Additional
       functions  include  sample  play,  A to B segment play, volume control,
       balance control,	etc.  Several automation options are also available on
       CD  load,  eject,  play completion and program exit.  A Channel Routing
       feature allow you  to  select  from  several  stereo  or	 mono  routing
       options.	  The  volume control slider taper characteristics can also be

       CDDA (CD	digital	audio) data extraction,	 playback,  save-to-file,  and
       pipe-to-program	are  supported on many platforms.  For data extraction
       to file or pipe,	xmcd can generate the data in MP3  (MPEG-1  layer  3),
       MPEG-2/MPEG-4 AAC, MP4, Ogg Vorbis, FLAC, WAV, AU, AIFF,	AIFF-C and raw
       headerless formats.  Simultaneous extraction to file/pipe and real-time
       playback	is possible on high performance	computers.

       Multi-disc changers are also supported.	There are buttons to switch to
       the next	or previous disc in the	changer, as well as a way to switch to
       a  specific  disc via the keypad.  You can select to play only a	single
       disc or auto-play all discs in normal or	reverse	order.

       The Gracenote CDDB(R) Music Recognition	Service(sm)  is	 supported  by
       xmcd,  which  allows  the  CD  artist/title and track titles, and other
       information associated with the loaded CD to  be	 displayed.   You  may
       also  add/modify	 and submit information	to the CDDB service.  For CDDA
       extraction to MP3, MP4, Ogg Vorbis and FLAC formats, xmcd can auto-fill
       the CD information tags embedded	in these files.

       This  release  of xmcd supports the enhanced Gracenote CDDB2(R) service
       on a number of platforms, and offers much richer	features  and  content
       than  the "classic" CDDB	service.  Moreover, CDDB2-supplied information
       is now in UTF-8 data format, providing international language  support.
       See "LOCALIZATION" below.

       Xmcd  provides  the  ability  to	drive a	web browser and	search for web
       sites related to	the currently playing CD artist	 or  track.   You  may
       also  access  online  music  reviews  and  go  to the official xmcd and
       Gracenote web sites, invoke the CDDB  Music  Browser(tm),  as  well  as
       CDDB-provided   links   to  related  content.   Moreover,  the  browser
       integration  gives  users  the  ability	to  manage  Local  Discography
       information pertaining to their CD collections.

       In addition to CDDB, this release of xmcd supports reading CD-TEXT data
       from the	disc for the disc/track	artist and title information.

       Full feature-specific  pop-up  help  is	available  for	all  controls,
       indicators, text	input fields, and lists.

       On  systems  with  more than one	CD drive, multiple invocations of xmcd
       can be used to operate each drive independently.

       Xmcd is designed	to be easy to use, as the  main	 window	 is  purposely
       made  to	 resemble  a  real  CD	player	front panel.  All other	pop-up
       windows are also	designed to be as intuitive  as	 possible.   Moreover,
       while  the  use	of a mouse is natural with xmcd, all functionality can
       also be operated	via the	keyboard.   This  is  in  conformance  to  the
       guidelines  published  in  the  OSF/Motif  Style	 Guide	from  the Open
       Software	Foundation.

       Many functions on a running xmcd	session	 can  be  "remote  controlled"
       from  the  command  line	 via  the  -remote  option.  See the "OPTIONS"
       section below.

       The internal architecture of xmcd is designed to	be easily portable  to
       many  UNIX operating system variants, and adaptable to the myriad of CD
       drives available.

       All standard Xt Intrinsics  toolkit  options  are  supported  (such  as
       -display,  -geometry.  -iconic,	etc.).	In addition, xmcd supports the
       following options:

       -dev device
	      Specifies	the path name to the raw CD device.  If	this option is
	      not  used,  the default device to	be used	is the first drive set
	      up with the xmcd configuration program (See below).

       -help  Causes command line usage	information to be displayed on stderr.

       -debug level#
	      Causes verbose debugging diagnostics to be displayed on  stderr.
	      The level	specifies the type of debugging	messages desired:

	      1	   General debugging
	      2	   Device I/O debugging
	      4	   CD information debugging
	      8	   User	interface debugging
	      16   Remote control debugging
	      32   Sound DSP and output	file/pipe debugging
	      64   Message of the day debugging

	      You  may	add  the  values together to enable multiple debugging
	      types (i.e., A value of 3	turns on both General and  Device  I/O

	      Causes  xmcd to install its own colormap.	 This may be desirable
	      if xmcd is to be used at the same	time as	other  color-intensive
	      applications,  which  would otherwise cause xmcd to be unable to
	      allocate all its needed colors.  Note that when running on an  X
	      display  that  does  not support many concurrent colormaps, this
	      may cause	other windows to change	colors when xmcd has the input

	      Causes  a	 command  to  be sent to another running xmcd process.
	      The command and  appropriate  arguments  are  specified  at  the
	      invoking	shell  (or  shell  script)  as command-line arguments,
	      After the	command	is delivered, the "sender" xmcd	process	exits,
	      and  the	"receiver"  process responds by	executing the command.
	      In effect, the sender becomes a remote  control  for  a  running
	      xmcd  session.   See  "COMMANDS"	below  for a list of supported

	      The sender xmcd process can be invoked on	the same host or on  a
	      different	 host than the receiver	xmcd process.  By default, the
	      sender will attempt to locate an xmcd  process  running  on  the
	      same  X  display (determined by the DISPLAY environment variable
	      or the -display option), and controlling	the  same  default  CD
	      device.	You  may  specify  the	device	via the	-dev option to
	      override the default.  Use of the	-dev and -rmthost  options  on
	      the sender's command line	can resolve ambiguities	when there are
	      multiple xmcd clients displaying on the same X server.

       -rmthost	hostname
	      This may be used with the	-remote	option to specify the host  on
	      which the	receiver xmcd client must be running.

       -c device (Solaris only)
	      Same as the -dev option.

       -X (Solaris only)
	      Causes the exitOnEject parameter to be set to True.

       -o (Solaris only)
	      This option has no effect.

       The -c, -X and -o options are provided only on the Solaris platform for
       compatibility with the	auto-startup program,  running
       under  the Solaris Volume Manager (vold).  See the PLATFORM file	in the
       xmcd  distribution  about  configuring  xmcd  for  the  Solaris	Volume

       Xmcd has	many adjustable	X resources to customize its look and feel, as
       well as its behavior.  Notably, the colors of virtually	every  feature
       on  xmcd's windows can be changed, as well as the text fonts.  All text
       labels can also be changed (for example,	to another language).

       There are too many resources to list here, but the resource  names  and
       their  defaults	(plus  descriptive  comments)  can  be	found  in  the
       XMCDLIB/app-defaults/XMcd file  (where  XMCDLIB	is  the	 xmcd  library
       directory  specified during installation, typically /usr/lib/X11/xmcd).
       It is not recommended  that  you	 change	 values	 in  the  XMCDLIB/app-
       defaults/XMcd  file,  unless you	want the changes to be forced upon all
       users of	xmcd on	the system.  Instead, make a copy of this file,	change
       the  copy  as  you  see	fit,  then  place  it  in  your	$HOME/.xmcdcfg
       directory.  Your	 custom	 resource  settings  will  then	 override  the
       defaults	when xmcd is subsequently started.

       You  may	 specify  a  command as	an xmcd	command	line argument, to make
       xmcd execute the	command	 after	initial	 startup.   For	 example,  the
       following command starts	xmcd and then begins playing at	track 4:

	   xmcd	play 4 &

       If  the	-remote	 option	 is  used, then	the command is sent to another
       running xmcd process for	execution (See "OPTIONS" above).

       The supported commands are:

       stop   Stop playback.

       play [track# | min:sec |	track#:min:sec]
	      Start playback.  You may also specify the	starting track number,
	      and/or the starting minute and second offset.

       pause  Pause the	playback.  You may resume the playback by using	either
	      the pause	command	again, or the play command.

       sample Start sample playback.  This will	play the first 10  seconds  of
	      each track.

       disc _load | eject | prev | next	| disc#_
	      Perform  a  disc	operation:  Load or eject the CD, or change to
	      another disc on a	multi-disc changer.

       track _prev | next | track#_
	      Perform a	track operation: Change	to the previous	or next	track,
	      or a specified track number.

       index _prev | next_
	      Perform  an  index  operation:  Change  to  the previous or next

       lock _on	| off_
	      Enable or	disable	the caddy (or disc tray) lock.	When  enabled,
	      pressing	the  eject  button on the drive	will not eject the CD.
	      You can only change the lock state when a	CD is  loaded  and  is
	      not playing.

       shuffle _on | off_
	      Enable  or  disable  shuffle (random play) mode.	Shuffle	can be
	      enabled in this manner only when playback	is  not	 in  progress.
	      When  shuffle  is	 enabled,  any program sequence	is cleared and
	      segment play is canceled.

       repeat _on | off_
	      Enable or	disable	repeat mode.

       program _clear |	save | track# ..._
	      Clear, save or set a track program sequence.  Track numbers  may
	      be  space	 or  comma-separated.	When  a	program	is set in this
	      manner, shuffle mode will	be disengaged and segment play will be

       volume _value# |	linear | square	| invsqr_
	      Volume  control  operation.   You	can specify a numeric value to
	      set the volume level (The	range is 0  to	100),  or  change  the
	      volume   control's  taper	 characteristic:  linear,  square,  or
	      inverse-square.	This  control  operates	 the  hardware	volume
	      control  on  the	CD  drive  in  Standard	 playback mode,	or the
	      computer's audio hardware	in CDDA	 playback  mode.   It  has  no
	      effect  on  the  data  of	 the CDDA save to file or CDDA pipe to
	      program outputs.

       balance value#
	      Balance control.	The value should be between 0 and 100.	 50 is
	      center,  0  is  full-left,  and 100 is full-right.  This control
	      operates the hardware volume control on the CD drive in Standard
	      playback mode, or	the computer's audio hardware in CDDA playback
	      mode.  It	has no effect on the data of the CDDA save to file  or
	      CDDA pipe	to program outputs.

       route _stereo | reverse | mono-l	| mono-r | mono	| value#_
	      Channel  routing	control.  Use one of the appropriate keywords,
	      or a value as follows:

	      0	   Normal stereo
	      1	   Reverse stereo
	      2	   Mono-L
	      3	   Mono-R
	      4	   Mono-L+R

       outport _speaker	| headphone | line-out | value#_
	      CDDA playback output port	selection.  The	speaker, headphone and
	      line-out keywords	are toggles.  Alternatively, you may specify a
	      numeric value, as	follows:

	      1	   Speaker
	      2	   Headphone
	      4	   Line-out

	      You may add the values together to enable	multiple output	 ports
	      (i.e., A value of	3 turns	on both	Speaker	and Headphones).  When
	      the value	is set to 0, the port  setting	is  unmodified.	  Note
	      that  this command may be	meaningful only	on some	platforms, and
	      only  certain  ports  may	  be   available   on	a   particular
	      architecture.  See the PLATFORM file for details.

       cdda-att	_value#_
	      CDDA  attenuator level.  The valid range is 0 to 100.  Note that
	      in contrast to the volume	command, this setting does not operate
	      any  hardware.   It works	by scaling the CDDA audio samples, and
	      thus has no effect in Standard playback mode,  but  affects  all
	      CDDA  modes  (CDDA  playback, CDDA save to file and CDDA pipe to

       time _elapse | e-seg | e-disc | r-trac |	r-seg |	r-disc_
	      Change the time display mode.  Select from elapsed  track	 time,
	      elapsed  segment	time, elapsed disc time, remaining track time,
	      remaining	segment	time or	remaining disc time.

       on-load _none | spindown	| autoplay | autolock |	noautolock_
	      Enable or	disable	options	when a CD  is  loaded.	 The  spindown
	      option  will  cause the CD to stop after loading to conserve the
	      laser and	motor.	The autoplay  option  will  cause  the	CD  to
	      automatically  start playing after loading.  The autolock	option
	      causes the caddy or disc tray to be automatically	 locked.   The
	      none, spindown and autoplay options are mutually-exclusive.

       on-exit _none | autostop	| autoeject_
	      Enable  or disable options when xmcd exits.  The autostop	option
	      will cause xmcd to stop playback,	and the	autoeject option  will
	      cause xmcd to eject the CD.  Use none to cancel these options.

       on-done _autoeject | noautoeject	| autoexit | noautoexit_
	      Enable  or disable options when xmcd is done with	playback.  The
	      autoeject	option causes xmcd to  eject  the  CD.	 The  autoexit
	      option will cause	xmcd to	exit.

       on-eject	_autoexit | noautoexit_
	      Enable  or  disable options when xmcd ejects a CD.  The autoexit
	      option will cause	xmcd to	exit after ejecting the	CD.

       changer _multiplay | nomultiplay	| reverse | noreverse_
	      Enable or	disable	multi-disc  changer  options.	The  multiplay
	      option  specifies	 that  xmcd  plays all discs in	sequence.  The
	      nomultiplay option will cause xmcd to  stop  after  the  current
	      disc is done.  The reverse option	implies	multiplay, except that
	      the disc order is	reversed.

       mode _standard |	cdda-play | cdda-save |	cdda-pipe_
	      Selects the playback  mode.   See	 "PLAYBACK  MODES"  below  for
	      details about the	modes.

       jittercorr _on |	off_
	      Enable or	disable	CDDA jitter correction.

       trackfile _on | off_
	      For  CDDA	 save  to file mode, specifies whether a separate file
	      should be	created	for each CD track.

       subst _on | off_
	      For CDDA save to file mode,  specifies  whether  space  and  tab
	      characters  in  the  output file path name should	be substituted
	      with  underscores	 ('_').	  This	makes  the  files  easier   to
	      manipulate while using the UNIX command shell.

       filefmt _format_
	      Specifies	 the  output audio file	format if running in CDDA save
	      to file or CDDA pipe to program modes.  The format is one	of the
	      following:  raw,	au,  wav, aiff,	aiff-c,	mp3, ogg, flac,	aac or

       outfile _template_
	      Specifies	the output audio file path name	template if running in
	      CDDA  save  to file mode.	 See the help file for the CDDA	output
	      file path	template text box for a	 description  on  the  special
	      tokens that could	be used	in the template.

       pipeprog	_path [arg ...]_
	      Specifies	the external program to	which the audio	stream will be
	      piped to when running in CDDA pipe to program mode.

       compress	__0 | 3_ [bitrate#] | _1 | 2_ [qual#]_
	      Selects the compression mode for	compressed  file  formats,  as

	      For MP3, the modes are as	follows:
	      0	   Constant bitrate (CBR)
	      1	   Variable bitrate (VBR, old algorithm)
	      2	   Variable bitrate (VBR, new algorithm, faster)
	      3	   Average bit rate (ABR)

	      For Ogg Vorbis and MP4, all modes	are VBR, as follows:
	      0, 3 Use an average bit rate
	      1, 2 Use a quality factor

	      For FLAC,	the modes are as follows:
	      0	   None
	      1	   Enable exhaustive LP	coefficient quant. search
	      2	   Enable encoding correctness verification
	      3	   Enable both

	      For AAC, all modes are VBR, as follows:
	      0	   Use an average bit rate, MPEG-2
	      1	   Use a quality factor, MPEG-2
	      2	   Use a quality factor, MPEG-4
	      3	   Use an average bit rate, MPEG-4

	      For  modes  0  and 3, an optional	bitrate	(in kb/s) sub-argument
	      can be specified.	 The supported bitrates	are a discrete set  of
	      numbers  from  32	 to  320.   A  value  of 0 can also be used to
	      indicate the use of an internal default.	For modes 1 and	2,  an
	      optional quality factor (from 1 to 10) sub-argument can be used.
	      Lower bitrates and quality factor	 values	 yield	smaller	 files
	      whereas  higher  numbers	produce	higher audio quality.  For AAC
	      and MP4 formats, the bitrate you	specify	 will  be  double  the
	      actual bitrate (e.g., if you specify 128kbps, the	actual bitrate
	      used will	 be  64kbps).	The  bitrate  or  quality  values,  if
	      specified, are ignored for the FLAC format.

       min-brate _bitrate#_
	      In  average  bitrate  and	 variable bitrate modes, this commands
	      lets you specify a low bitrate limit.  The encoder will not drop
	      below  this  limit  while	 dynamically  changing the bitrate.  A
	      value of 0 can be	specified to indicate the use of  an  internal
	      default.	 This  parameter has no	effect on the FLAC, AAC	or MP4

       max-brate _bitrate#_
	      In average bitrate and variable  bitrate	modes,	this  commands
	      lets  you	specify	a high bitrate limit.  The encoder will	not go
	      above this limit while  dynamically  changing  the  bitrate.   A
	      value  of	 0 can be specified to indicate	the use	of an internal
	      default.	This parameter has no effect on	the FLAC, AAC  or  MP4

       coding _stereo |	j-stereo | force-ms | mono | algo#_
	      This  command  selects  the  stereo  mode	 and  encoding	noise-
	      shaping/psychoacoustics algorithm.

	      For MP3, the algorithm is	a number from 1	to 10.	Lower  numbers
	      gives  faster  encoding  whereas	higher	numbers	produce	higher
	      audio quality.

	      For AAC and MP4, stereo disables the mid/side  coding,  j-stereo
	      and  force-ms  are  synonymous,  and  mono is not	supported.  An
	      algorithm	value of 10 enables temporal noise shaping (TNS).

	      For FLAC,	the stereo modes have no  effect,  but	the  algorithm
	      value  selects  between  faster  encoding	versus slightly	better

	      For Ogg Vorbis, this parameter has no effect.

       lowpass _off | auto | freq# [width#]_
	      This allows a lowpass filter to be added.	 The off setting means
	      no  filter,  the	auto  setting  causes the encoder to determine
	      whether a	filter should be added and its parameters.  Specifying
	      a	 frequency (and	optionally, a width) will enable the filter in
	      manual mode.  The	frequency and width are	both in	Hz.  The valid
	      frequency	 range	is  from  16 to	50000 Hz.  For MP3, the	filter
	      functions	fully as described.  For AAC and MP4, the freq can  be
	      used  to	limit  the  bandwidth, but the width value is ignored.
	      For Ogg Vorbis and FLAC, these parameters	have no	effect.

       highpass	_off | auto | freq# [width#]_
	      For encoding to MP3 files, this allows a highpass	filter	to  be
	      added.  The off setting means no filter, the auto	setting	causes
	      the encoder to determine whether a filter	should	be  added  and
	      its  parameters.	 Specifying  a	frequency  (and	 optionally, a
	      width) will enable the filter in manual mode.  The frequency and
	      width  are both in Hz.  The valid	frequency range	is from	500 to
	      50000 Hz.	 The lower limit is imposed by	the  polyphase	filter
	      implementation  in  the MP3 encoder.  For	non-MP3	formats, these
	      parameters have no effect.

       flags _[C|c][O|o][P|p][E|e][I|i]_
	      This allows you to specify some MP3 header and frame flags.  The
	      letter  c	denotes	the "copyright"	flag, the letter o denotes the
	      "original" flag, the letter n denotes the	"no res" (disable  bit
	      reservoir)  flag,	 the letter e denotes the addition of a	2-byte
	      checksum to each frame for error correction, and	the  letter  i
	      indicates	 strict	 ISO  compatibility.   The use of a upper-case
	      letter turns on the flag,	and lower-case	turns  off  the	 flag.
	      Multiple flags may be specified together.

       tag _off	| v1 | v2 | both_
	      This command specifies whether CD	information (such as album and
	      track artists and	titles,	genre type, etc.) should be  added  to
	      the  CDDA	 output	 file.	 For  MP3, the information is added to
	      either the version 1, version 2 or both versions of the ID3  tag
	      areas.   For  Ogg	Vorbis,	FLAC and MP4, the information is added
	      to the metadata area.  to
	      Note: An ID3v2 tag will not be added to the CDDA pipe to program
	      MP3 stream regardless of the setting of this command.

       lameopts	__disable | insert | append | replace_ [options]_
	      This  command allows you to query	or set command line options to
	      be passed	directly to the	LAME  MP3  encoder,  and  control  how
	      those  options  will  be	passed.	  This	facilitates the	use of
	      advanced or experimental LAME features that cannot otherwise  be
	      invoked  via  the	 xmcd  graphical  user	interface  for setting
	      encoding parameters.  The	following  keywords  control  how  the
	      command line options are to be passed:

	      disable: No additional command line options are to be passed.
	      insert:  The  specified  options	are  to	be inserted before the
	      standard options.
	      append: The specified options  are  to  be  appended  after  the
	      standard options.
	      replace:	The  specified	options	 are to	be used	instead	of the
	      standard options.

	      Standard options refers to the command line  options  that  xmcd
	      generates,  based	on the current settings	of the controls	in the
	      "Encoding	Parameters" options window.

       motd   Retrieve and display messages from the xmcd MOTD server, if any.

       window _modechg | iconify | deiconify | raise | lower_
	      Xmcd window control.  The	modechg	command	causes the main	window
	      to  toggle  between  the	normal mode and	basic mode.  In	normal
	      mode, all	controls and indicators	are available.	In basic mode,
	      xmcd  shrinks  to	 a  smaller  size  and only basic controls are
	      shown.  The iconify, deiconify, raise and	lower  commands	 cause
	      the xmcd window to change	as specified.

       quit   Causes xmcd to exit.

       debug _level#_
	      Set  the	debug  level.	When  debug  level  is	non-zero, xmcd
	      generates	verbose	 debugging  diagnostics	 to  be	 displayed  on
	      stderr.	See  the  description  for the -debug option above for
	      supported	level values.

       Some of these commands, when used in start-up mode, do  not  perform  a
       meaningful  function.   For  example,  the  "track prev"	command	is not
       useful just after xmcd startup.	It is more  appropriate	 to  use  this
       command in the remote control mode.

       The  X  resources  described in the previous section affect the general
       appearance  and	behavior  of   xmcd.	There	are   two   additional
       configuration  files  which  are	 used  to  adapt  xmcd	to  your  site
       requirements.  The first	of these contain common	 parameters,  and  the
       second  contain	configurable  parameters that must vary	on a per-drive
       basis.  For  example,  in  some	cases  xmcd  must  operate  the	 drive
       differently  depending  upon  the  brand	and model of the drive.	 Thus,
       there must be a separate	configuration file for these  parameters  per-
       device.	 The  common  parameters file is XMCDLIB/config/common.cfg and
       the device-specific parameters  file  is	 XMCDLIB/config/DEVICE	(where
       XMCDLIB	is  typically /usr/lib/X11/xmcd	and DEVICE is the base name of
       the   raw   device   special   file   for   the	 CD    drive;	 e.g.,
       /usr/lib/X11/xmcd/config/rcd0).	     A	    configuration      program
       XMCDLIB/config/	 is  provided  to   make   maintaining	 these
       configuration  file  easy  (Note:  on SCO UNIX/Open Desktop/Open	Server
       systems the configuration program can also be invoked as	"mkdev xmcd").

       You  should  always  use	 the  configuration   program	to   set   the
       configuration  parameters  when	installing xmcd	for the	first time, or
       when the	CD hardware configuration has changed.	If this	 is  not  done
       then xmcd will probably not operate correctly with your CD drive.

       WARNING:	 If  xmcd  is  not correctly configured, you may cause xmcd to
       deliver commands	that are not supported by your CD drive.   Under  some
       environments this may lead to system hang or crash.

       You  can	 override some of the device-specific configuration parameters
       by adding your own configuration	files.	Xmcd will  also	 look  in  the
       $HOME/.xmcdcfg/common.cfg  and  $HOME/.xmcdcfg/DEVICE  files for	common
       and device-specific parameters (where $HOME is your home	directory  and
       DEVICE  is  as  specified  above).   Parameters found in	this file will
       override	the system defaults (except those parameters  that  cannot  be
       overridden;  see	 the  comments	in  the	 XMCDLIB/config/device.cfg for

       The basic functions of xmcd are designed	to operate the same way	as  on
       a real stereo CD	player.	 The pictorial symbols used on the main	window
       buttons are intended to illustrate  the	function  in  a	 non-language-
       specific	 manner.   If  enabled,	 a small "tooltip" will	appear after a
       short delay, when you position the mouse	 cursor	 over  any  xmcd  main
       window  feature.	  The  tooltip	contains  textual  description	of the

       The CD information and track programming	functions are operated via the
       CD  Information	subwindow.   You open the subwindow by clicking	the CD
       Information button (file	cabinet	symbol)	on the main  window  (See  "CD
       DATABASE" below).

       There  is  not a	per-item description of	all the	features here, because
       full on-line help is available (See "ONLINE HELP" below).

       For general information about xmcd, click the  wwwWarp  (world  symbol)
       button  on  the xmcd main window	and select 'Xmcd help...' in the menu.
       You can also get	specific help information about	each button,  control,
       indicator,  text	 entry	area,  selection list by positioning the mouse
       cursor over the desired item, then clicking the third mouse button.   A
       pop-up window will appear, containing the relevant help text.

       You can program xmcd to play only certain tracks, in a custom sequence.
       To do so,  invoke  the  CD  Information	window	(by  clicking  the  CD
       Information  button  on	the main window).  Select the desired track by
       clicking	on the entry in	the Track list,	and click the  Add  button  to
       add  to the play	sequence.  Notice that the track number	appears	in the
       Program sequence	text field.  You can  also  type  the  track  numbers,
       separated  with	commas	or  spaces,  directly  in the Program sequence
       field.  Repeat until all	desired	tracks have been entered,  then	 click
       the Play/Pause button (on the main window) to start the program play.

       When  a	program	 sequence  is  defined,	the prog indicator in the main
       window display area "illuminates".   To	erase  the  program  sequence,
       click the Clear button on the CD	Information window.  You may also Save
       a program sequence, so that the next time you  load  the	 same  CD  the
       program	will  automatically  be	 applied.   The	Clear button will also
       delete the saved	program.

       Unless explicitly disabled, xmcd	will automatically query the Gracenote
       CDDB  Music  Recognition	 Service  for information about	the loaded CD.
       This information	includes the artist/title, track  titles,  genre,  and
       much more, and is displayed on the CD Information window	and several of
       its sub-windows.

       You may also add, modify	or enhance the displayed information,  in  the
       rare  circumstance  that	CDDB does not have data	pertaining to your CD,
       or if the CDDB-supplied data is incomplete or in	error.	You  can  then
       submit the changes back to CDDB.

       You should perform a "submit" operation (click the Submit button) after
       typing in the changed information before	ejecting the CD	or exiting, or
       the information will be lost.

       The CD Information window should	prove to be intuitive to use.  You may
       use the on-line help system to obtain specific help  information	 about
       the various buttons and items.

       The  CD information, once queried from CDDB, is stored in a local cache
       and managed by the CDDB library.	  This	reduces	 unnecessary  Internet
       connections to the CDDB servers.

       This  release  of  xmcd also supports reading the CD-TEXT data from the
       disc for	CD information.	 Only some recent CDs are  produced  with  CD-
       TEXT  data  and	this  data  can	only be	read on	CD drives with CD-TEXT

       For backward compatibility, this	release	of xmcd	 will  also  read  the
       old-style local CD database files previously generated by xmcd versions
       1.x and 2.x.  No	capability is retained in this release to write/update
       the old-style CD	database files.

       The  priority  of the CD	information schemes (CDDB, CD-TEXT or local CD
       database	files) is controlled  via  the	cdinfoPath  parameter  in  the
       common.cfg file.

       For  more information about Gracenote CDDB, read	the CDDB file included
       with this release, and  visit  the	web  site  for

       While  xmcd is running, the file	/tmp/.cdaudio/curr.nnnn	(where nnnn is
       the  hexadecimal	 representation	 of  the  CD  drive's  device  number)
       contains	the device node	path, the music	genre, and disc	identification
       information pertaining to the currently loaded CD.  Other  applications
       may read	this file to identify the currently loaded disc.

       This release supports the following user-selectable playback modes (via
       the Options pop-up window):

       Standard	playback
	      When playing an audio CD,	the audio output is the	 analog	 "line
	      out"  connection	on the back of your CD drive.  There should be
	      an audio cable connecting	this output  to	 your  computer	 audio
	      hardware	CD  input  (or	to  an	externally amplfied speaker or
	      stereo system).  The audio output	is also	available  at  the  CD
	      drive's  front  panel headphone connection, if so	equipped.  The
	      volume control slider bar	on xmcd	affect the CD drive's built-in
	      volume  control,	if  the	 drive has such	controls.  This	is the
	      mode that	previous  releases  (xmcd  version  1.x	 through  3.0)

       CDDA playback
	      When  playing  a	CD  in this mode, xmcd extracts	the CD digital
	      audio data off the CD drive over the data	cable (e.g.,  SCSI  or
	      ATAPI/IDE).   Then, it sends the data to the DSP (digital	signal
	      processor) device	in your	computer's audio  hardware  for	 real-
	      time  playback.	The  audio  is	typically  heard  through  the
	      computer's built-in speakers.  No	 signal	 is  produced  at  the
	      line-out	or  headphone  connections  of the CD drive.  The xmcd
	      volume control slider bar	affects	the computer's DSP device.

       CDDA save to file
	      When playing a CD	in this	mode, xmcd  extracts  the  CD  digital
	      audio  data  off the CD drive over the data cable	(e.g., SCSI or
	      ATAPI/IDE).  Then, it writes  the	 data  into  a	file  of  your
	      choosing.	  The  xmcd  volume control slider does	not affect the
	      data written to the output file.	The output file	format can  be
	      selected to be one of the	following:

	      Format Ext   Description
	      ------ ----- ---------------------------------------
	      RAW    .raw  Little-endian, 16 bit, 44.1 kHz, stereo
	      AU     .au   Big-endian, 16 bit, 44.1 kHz, stereo
	      WAV    .wav  Little-endian, 16 bit, 44.1 kHz, stereo
	      AIFF   .aiff Big-endian, 16 bit, 44.1 kHz, stereo
	      AIFF-C .aifc Big-endian, 16 bit, 44.1 kHz, stereo
	      MP3    .mp3  MPEG	1.0 Layer III compressed
	      Ogg    .ogg  Ogg Vorbis compressed
	      FLAC   .flac Free	Lossless Audio CODEC compressed
	      AAC    .aac  AAC (MPEG-2 or MPEG-4) compressed
	      MP4    .mp4  MP4 (MPEG-4)	compressed

	      The  file	 can  be  played  later	 using an appropriate playback
	      utility,	or  converted  to  another  format.   This  mode  will
	      typically	 run  faster  than  real-time  with the	non-compressed
	      formats.	With the compressed formats, it	 depends  on  the  CPU
	      performance of your system.

       CDDA pipe to program
	      When  playing  a	CD  in this mode, xmcd extracts	the CD digital
	      audio data off the CD drive over the data	cable (e.g.,  SCSI  or
	      ATAPI/IDE).   Then,  it  pipes  the  data	 stream	to an external
	      program that you specify.	 The output format is selected	as  in
	      the  CDDA	 save  to  file	 mode.	 This mode can be used with an
	      external	audio  player,	encoder,  or   other   digital	 audio
	      manipulation  program.   The external program must be capable of
	      accepting	audio data on  its  standard  input,  in  one  of  the
	      formats listed above.

       More than one of	the three CDDA modes can be selected at	the same time.
       For example, if both the	CDDA  playback	and  the  CDDA	save  to  file
       buttons	 are   selected,   the	 two   functions   will	 be  performed
       simultaneously.	Note that on most systems, only	one program can	access
       the  system's  DSP  at a	time, therefore	you will likely	not be able to
       select CDDA playback and	CDDA pipe to program at	the same  time,	 where
       the external program is itself an audio player.

       NOTE: The CDDA (CD digital audio) modes will function only on CD	drives
       that provides this  capability,	and  only  on  some  OS	 and  hardware
       platforms.   See	 the  RELNOTES file for	details	about platform support
       and other CDDA related notes.

       There is	full localization support in xmcd if it	is compiled with X11R5
       or later	header files and libraries.

       The  "classic"  CDDB  service  supplies	data in	the ISO	Latin-1	format
       only, multi-byte	characters are not supported.

       The CDDB2  service  supplies  data  in  UTF-8  data  format,  which  is
       identical  to  US-ASCII	for  single-byte characters.  Multi-byte UTF-8
       characters are also supported when xmcd is linked with X11R5 or	later.
       By  default,  xmcd  will	 translate  the	characters to ISO Latin-1 (ISO
       8859-1, for English and many European character sets).  By changing the
       setting	of  the	 charsetConvMode parameter in the common.cfg file, you
       can have	xmcd display the UTF-8 data without conversion (good  for  US-
       ASCII  or  if  you  are using UTF-8 fonts), or attempt to convert UTF-8
       strings	to  the	 default  character  set  as  specified	 by  the  LANG
       environment  variable.  This conversion will occur only if the system's
       list of locales also support UTF-8.  As distributed, xmcd is configured
       to  display  in	a  generic  family  of	X fonts	denotes	similar	to the


       This will normally work correctly with  English	and  any  ISO  Latin-1
       European	 character  set, as long as your X display server supports all
       the required fonts.  To display in other	languages, you must  set  your
       LANG  environment  accordingly,	and change xmcd	to use the appropriate
       fonts.	That  can   be	 accomplished	by   modifying	 the   various
       XMcd*classname.fontList	parameters  in	the  XMCDLIB/app-defaults/XMcd
       file (system wide) or your  $HOME/.xmcdcfg/XMcd	file  (per-user).   Be
       sure that the fonts you specify is actually supported by	your X display
       server.	See xlsfonts(1)	and your X window system  documentation	 about
       font configuration.

       Moreover,  all  titles and descriptions in xmcd are configurable	in the
       XMcd X resource file.  US-English is distributed	by  default,  but  the
       file  may  be  modified	to  use	any other language as desired.	See "X
       RESOURCES" above.

       Not all platforms and CD	drives support all the features	of xmcd.   For
       example,	 some  drives do not support a software-driven volume control.
       On these	drives the xmcd	volume control slider may have no  effect,  or
       in  some	 cases it is made to function as a mute	control	(i.e., it will
       snap to the full-off or full-on positions only).	 Similarly, the	 caddy
       lock,  eject  and  index	 search	buttons	found on xmcd may not have any
       effect on drives	that do	not support the	appropriate functionality.

       The remote control feature (using the -remote option)  is  governed  by
       the standard display server security mechanisms of the X	window system.
       In order	for an xmcd sender client to communicate with a	 running  xmcd
       receiver	  client,   the	  sender  must	have  the  appropriate	access
       permissions to the receiver client's X display.	See xhost(1), xauth(1)
       and  Xsecurity(1)  for more information.	 If logging is enabled,	remote
       control	activity  is  logged  by  the  xmcd  receiver  client  in  the
       $HOME/.xmcdcfg/remote.log file for each xmcd user.

       The  lame(1)  MP3  encoder  program must	be installed on	your system in
       order for xmcd to perform CD ripping to MP3 format  files.   Similarly,
       the  faac(1)  encoder  program must be installed	on your	system for the
       AAC and MP4 formats.

       Your copy of the	xmcd executable	must be	compiled and linked  with  the
       Ogg Vorbis and FLAC encoder libraries in	order to perform CD ripping to
       these formats.  See the INSTALL file for	details.

       The LANG	environment variable sets  the	default	 character  set.   See
       "LOCALIZATION" above.

       For  the	wwwWarp	feature, xmcd invokes the Netscape, Mozilla, Galeon or
       Opera web browser to display the	contents.  Xmcd	searches a  number  of
       "standard"  locations  for  the	web  browser  executable.  If you have
       multiple	browsers installed and would like to  direct  xmcd  to	use  a
       particular  executable, or if your browser executable is	installed in a
       non-standard location, then you may set	the  BROWSER_PATH  environment
       variable	 on  the  shell	command	line to	the web	browser	executable you

       An example:

	   (For	Bourne Shell and Korn Shell users):
	   BROWSER_PATH=/usr/local/bin/mozilla;	export BROWSER_PATH

	   (For	C Shell	users):
	   setenv BROWSER_PATH /usr/local/bin/mozilla

       you may put the	above  command	in  your  $HOME/.profile  (sh/ksh)  or
       $HOME/.cshrc (csh) to set this automatically each time you log in.

       The  LAME_PATH  environment variable may	be used	to specify the path to
       the lame(1) MP3 encoder program.

       The FAAC_PATH environment variable may be used to specify the  path  to
       the faac(1) AAC and MP4 encoder program.

       The  AUDIODEV  environment variable may be used to specify an alternate
       audio device when running xmcd in the CDDA playback mode.  The  default
       audio device is write method dependent as follows:

	   AIX write method:   /dev/paud0/1   (PCI audio)
	   AIX write method:   /dev/baud0/1   (MCA audio)
	   ALSA	write method:  plughw:0,0
	   HP-UX write method: /dev/audio
	   Linux/OSS write method:  /dev/dsp
	   OSF1	write method:  0
	   Solaris write method:    /dev/audio

       In  addition,  with  the	 OSS  and  ALSA	 write	methods,  the MIXERDEV
       environment variable may	be used	 to  specify  the  PCM	mixer  channel
       device.	The default is /dev/mixer for OSS, and default for ALSA.

       On FreeBSD with ATAPI CD	drives,	xmcd will automatically	use either the
       CDIOCREADAUDIO ioctl or the pread(2) system call	for CDDA reads,	 based
       on the running kernel version.  You may override	the default by setting
       the environment	variable  CDDA_USE_PREAD  to  0	 or  1,	 respectively.
       Normally	this is	not necessary.
