NAME
       mp3blaster - An interactive text-console	based mp3 player.

SYNOPSIS
       mp3blaster [options]

       mp3blaster [options]  [file ...]
	      Play one or more audio files from	the command-line

       mp3blaster [options] --list|-l playlist.lst
	      Load a playlist at startup but don't start playing.

       mp3blaster [options] --autolist|-a playlist.lst
	      Load a playlist at startup and start playing.

DESCRIPTION
       Mp3blaster  is  an  interactive	audio player for the text-console with
       unique playlist abilities no other programs offer. Its interface	is  at
       least  equally  powerful	 as those featured in GUI players, without re-
       quiring bulky graphical environments.

       The most	important feature of mp3blaster	however	is the playlist, which
       structure  is  comparable to that of a filesystem: Songs	(files)	can be
       grouped together	in `groups' (directories). With	one function, you  can
       load  all your albums as	groups into mp3blaster's playlist, so that you
       can shuffle your	albums instead of your songs. Of course, you can  also
       load  all  files	 into the playlist and shuffle them, just like regular
       players.

       The interface is	described in the INTERFACE ELEMENTS section.

       The configuration file is described in the MP3BLASTERRC section.

       The different program modes are described in the	PROGRAM	MODES section.

       The playlist playback modes are described in the	PLAYMODES section.

       Who coded this program? How to report bugs? It's	 in  the  AUTHORS  and
       BUGS section at the end of this manual.

COMMAND-LINE PARAMETERS
       --downsample,-2
	      Downsample audio to 22Khz	(necessary on some ancient soundcards,
	      but it can also be used to use less CPU time)

       --8bits,-8
	      Convert audio to 8bits (necessary	on 8bit	soundcards, but	it can
	      also be used to use less CPU time)

       --chroot=rootdir, -o=rootdir
	      Set  <rootdir>  as  mp3blaster's root dir. This affects ALL file
	      operations in mp3blaster!! (including  reading  and  writing  of
	      playlists).  Note	that only users	with uid 0 (i.e. root) can use
	      this option (yet). This feature should be	changed	 so  it	 won't
	      require  root privileges.	Only install it	suid root if you trust
	      all local	users!!!!.

       --config-file,-c=<file>
	      Use <file> as config-file	instead	of ~/.mp3blasterrc

       --debug,	-d
	      Log debug-info in	$HOME/.mp3blaster (use this when  sending  bu-
	      greports!)

       --status-file, -f
	      Write info on the	mp3's being played to the specified file.

       --help,-h
	      Gets you this nice list of command-line parameters.

       --mixer-device/-m=<devicename>
	      Set  the mixer device to use (default = /dev/mixer). For NAS au-
	      dio mixing, use 'NAS'.  (NOTE: NAS support doesn't work in  ver-
	      sion 3.0 or above	yet)

       --no-mixer, -n
	      Don't start the built-in mixer.

       --playmode/-p=(onegroup,allgroups,allrandom}
	      Default  playing	mode  is resp. Play first group	only, Play all
	      groups, Play all songs in	random order.

       --dont-quit,-q
	      Don't quit after playing all command-line	supplied  mp3's	 (only
	      makes  sense  in	combination with --autolist or files from com-
	      mand-line)

       --repeat/-R
	      Repeat the playlist indefinitely.

       --runframes/-r=<number>
	      Number or	frames to decode in one	loop.  Range:  1  to  10  (de-
	      fault=5).	  On slow machines, a lower number might improve reac-
	      tion time	of the interface, but it's quite  unlikely  this  will
	      have any effect from version 3.0 on)

       --sound-device/-s=<devicename>
	      Select  the audio	device you wish	to use for sound playback (de-
	      fault /dev/dsp or	/dev/audio for OpenBSD). If you	want  to  play
	      over  NAS	(Network Audio System),	give the audioserver's address
	      here (usually $DISPLAY, e.g. a host name followed	by a colon and
	      a	server number, like bla.foo.com:0). (NOTE: NAS support doesn't
	      work in version 3.0 or above yet)

       --threads/-t=<amount>
	      Numbers of threads to use	for buffering. Range is	0..500 in  in-
	      crements	of  50.	  0 threads means no buffering (thus no	hiccup
	      prevention).

       --version,-v
	      Displays mp3blaster's version number.

INTERFACE ELEMENTS
       Since version 3.0, mp3blaster's interface has  changed  drastically  to
       make it easier to use, without losing functionality. Press '?' to get a
       description of all the commands within mp3blaster. You  can  scroll  up
       and  down  this	helpfile using the cursor keys and pageup/pagedown. To
       leave the help, press '?' again.

       All keybindings mentioned from here on  are  the	 default  keybindings.
       Most  of	 them  can be altered in mp3blaster's config file (see section
       MP3BLASTERRC)

       Keybindings window
	      In the top of the	screen is the keybindings window.  In  it  you
	      will  find  all  keybindings  that  you  can  use	 in  the  mode
	      mp3blaster is in at that time.  If you change  modes,  the  key-
	      bindings are dynamically updated.	To scroll through this window,
	      use '-' and '+'.

       Info window
	      This window is located directly beneath the keybindings  window.
	      It displays the global playmode (see section PLAYMODES), and the
	      next song	to be played (if appropriate). Next to it is  a	 small
	      window  which  displays  technical information about the current
	      song.

       Main window
	      This window is located directly underneath the info window.  Its
	      content  is usually determined by	the mode mp3blaster is in (see
	      section PROGRAM MODES).  If you're  editing  the	playlist,  the
	      playlist is shown. In file manager mode, you will	see the	direc-
	      tory you're currently in.	In help	mode, the help text  is	 being
	      displayed.

       CD-style	window
	      This  is	the window next	to the main window. Here you will find
	      the cd-style controls, as	well as	checkboxes for	shuffle/repeat
	      mode. When a song	is being played, you can see the elapsed/total
	      time here	as well.

       Status window
	      It's underneath the main window, and displays status information
	      like  song title,	hints, etc. In the top-left, a CD-player style
	      symbol is	shown to indicate  what	 mp3blaster  is	 doing	during
	      playback.

       Mixer window
	      The mixer	is right next to the status window. Although very com-
	      pact, it's a full	sound mixer. Press 't' to toggle  between  all
	      available	mixer devices.	Press '<' and '>' to decrease/increase
	      the volume of the	currently selected mixer device.

PROGRAM	MODES
       Playlist	Editor
	      By default, mp3blaster starts with the playlist editor. All key-
	      bindings specific	to playlist editing are	listed in the keybind-
	      ings window.  The	playlist consists of one or more groups.  Each
	      group can	have its own groupname and can contain supported audio
	      files. You can toggle shuffle mode for each group	independently.
	      Many  users  will	 simply	 use  the  single  (root)  group  that
	      mp3blaster starts	with. In that case,  shuffling	all  songs  is
	      simply  a	 question  of  toggling	the GroupShuffle mode (default
	      keybinding: F7).

	      If you have multiple groups, and you want	to shuffle  all	 songs
	      from  all	 groups, you will have to set the global playback mode
	      (see section PLAYMODES). Without shuffling, the  songs  will  be
	      played in	the order you added them from the file manager.	Groups
	      can be nested inside other groups. For example, you could	make a
	      group  for  each	music genre you	are interested in. Within each
	      genre, you can add subgenres, and	in the subgenres you  can  add
	      albums  as  groups. Starting and stopping	a playlist can be done
	      with '5' (default	keybinding for the Play	button). If  you  stop
	      playback using the Stop button, all information about which song
	      has already been played is lost. If you want to stop playback to
	      continue later, pause the	current	song.
	      In the main window, the contents of the currently	selected group
	      is shown.	 By default, this is the 'root'	 group.	 Other	groups
	      are  denoted by square brackets and a purple colour. You can en-
	      ter other	groups simply by highlighting them and pressing	enter.
	      If  you enter the	file manager, files will be added in the group
	      that was selected	in  the	 main  window.	This  even  works  for
	      playlists;  if  you load a playlist from the file	manager	(which
	      you always do), it will be added in  the	current	 group!	 Using
	      this feature, you	can merge multiple playlists into one.
	      If  you're  listening  to	your current playlist, but you want to
	      hear another song	in between, you	can simply do so by highlight-
	      ing this song (either in playlist	mode or	file manager mode) and
	      pressing enter. When the song is finished, the playlist  contin-
	      ues with the next	song in	the list.

       File Manager
	      You  can enter the file manager by pressing F1 from the playlist
	      editor. The  interface  is  almost  identical  to	 that  of  the
	      playlist	editor,	but you	can tell the mode you're in by looking
	      at the keybindings in the	keybindings window which is  automati-
	      cally  updated.	In  the	file manager, you can add files	to the
	      group you	had currently selected in the playlist editor. You can
	      also  listen  to a file by selecting it with the highlighted bar
	      and pressing enter over it.  Adding files	can be done in 2 ways:
	      Selecting	 a  file  by  moving  the bar over it and pressing the
	      spacebar,	or by recursively selecting all	files in  the  current
	      directory	 and  all directories in it. If	you select some	files,
	      change to	another	directory (by pressing	enter  over  one)  and
	      then select some more files, the old selection will not be lost,
	      even though you can't see	it on your screen at the time. As soon
	      as  you  return to the playlist editor by	using F1, you will see
	      they have	been added to the group	in the order in	which you  se-
	      lected them.  However, you can't deselect	selected files as soon
	      as you change into another directory: you'll have	to remove them
	      from  the	playlist editor.  A quick way of selecting *all* files
	      in the current directory is to invert the	selection  (using  F2)
	      when none	are selected. If you want to select all	files but one,
	      select the one you don't want and	then invert the	selection.
	      The recursive selection can be done in two ways: By pressing F3,
	      you  add	all audiofiles that are	found in the current directory
	      and all directories in it.  By using F5 (add  dirs  as  groups),
	      mp3's  are added in groups that are named	like the directory the
	      mp3's were in. This is  an  ultimately  fast  way	 of  making  a
	      playlist grouped by albums!
	      Help  for	 other	keybindings  can be found inside mp3blaster by
	      pressing '?'  (note that this leaves file	manager	mode!)

       Help mode
	      You can get in this mode by pressing '?'.	Leave it  by  pressing
	      '?' again.  It will always return	you to playlist	mode.

       Playing Mode
	      Mp3blaster  versions  prior to version 3.0 featured another dis-
	      tinctly different	mode: the playing mode.	The  reason  for  this
	      was that it wasn't possible to edit a playlist and play mp3's at
	      the same time. Since this	is now possible, playing songs is pos-
	      sible in all program modes. Keybindings specific to playback are
	      always listed in the keybindings window.

PLAYMODES
       The order in which files	are played in the playlist  is	determined  by
       two  settings: The global playback mode (displayed in the info window),
       and each	group's	independent shuffle setting. The  'current  group'  in
       the  global  playback  modes means: The group that is shown in the main
       window at the time the playlist was started. This is  important,	 since
       it enables you to play a	subsection of your playlist instead of playing
       the entire list.
       These are the global playback modes:

       Play current group, including subgroups
	      Plays all	songs shown in the current group, as well as all songs
	      in  all subgroups. First,	all groups will	be played in the order
	      you have added them (unless the current group's shuffle  is  en-
	      abled,  then  the	order is randomly determined). Then, the songs
	      in the group itself will be played.  You can determine for  each
	      individual  group	 whether you want to shuffle the songs in them
	      or not, by enabling the group's shuffle setting.

       Play current group, but not its subgroups
	      This is essentially the same as the previous mode,  except  that
	      subgroups	in this	group will be skipped.

       Shuffle all songs from all groups
	      This  is	comparable to the 'shuffle' mode that all players sup-
	      port: It ignores the group structure totally, and	 simply	 shuf-
	      fles all songs in	a completely random order.

MP3BLASTERRC
       You  can	 store	many settings and keybindings in a config file.	By de-
       fault, mp3blaster will look for ~/.mp3blasterrc,	unless you specify an-
       other file on the command-line (using -c/--config-file).

       The  structure  of  the	config file is pretty straightforward. Look at
       sample.mp3blasterrc in your share or share/doc directory	 for  a	 quick
       example.	  Lines	 starting  with	a '#' are ignored. You can use them to
       put comments on.	 All other lines consist of a keyword/value pair  like
       this:

       Keyword = Value

       Some keywords can have multiple values, in that case it's:

       Keyword = Value1, Value2

       Escape  comma's	in  a value with a backslash (). If you	want a literal
       backslash, escape it with another backslash (\).	Keywords are case-sen-
       sitive.

       There  are  a  few  types  of  values:  numbers,	booleans, keybindings,
       colours,	and everything else is a string. The  syntax  of  these	 types
       are:

       numbers
	      Numerical	values,	in decimal notation.

       booleans
	      yes/no, 1/0, or true/false (case-insensitive)

       keybindings
	      Single-character	keybindings  represent themselves. If you want
	      to specify a scancode, the syntax	is  's<hex-digit><hex-digit>'.
	      All  others  are	special	 canonical names: 'spc'	(space), 'ent'
	      (enter),	'kp0'..'kp9'  (keypad  0..9),  'ins'  (insert),	 'hom'
	      (home),  'del'  (delete),	 'end'	(end),	'pup'  (pageup), 'pdn'
	      (pagedown), 'f1'..'f12', 'up'/'dwn'/'lft'/'rig'  (cursor	keys),
	      'bsp' (backspace).

       colours
	      One of: black, red, green, yellow, blue, magenta,	cyan, white

       These keywords are currently supported:

       AudioDriver (string)
	      Which audiodriver	to use for playback. Currently,	you can	choose
	      between the following drivers: oss, esd, nas and sdl. If SDL  is
	      available,  it will be used by default. OSS is the next alterna-
	      tive. ESD	should only be used if everything  else	 fails.	  Note
	      that,  if	 you use SDL as	audio driver, you can select from many
	      output devices by	setting	the  environment  variable  SDL_AUDIO-
	      DRIVER.  This is an SDL feature, please refer to the FAQ on lib-
	      sdl.org for more information.

       AudiofileMatching (list of strings)
	      List of file patterns (in	regexp format) that  determines	 which
	      files  will  be considered audiofiles (default: all files	ending
	      on .mp3, .wav,  and  files  starting  with  'http://'  for  http
	      streaming). Check	sample.mp3blasterrc for	a good example.

       CharsetTable (string)
	      Specify  a  character  recoding table which maps ID3 songinfo to
	      your local charset. For more info	about how to create  one,  see
	      the  README  in  the installed mp3blaster	documentation (usually
	      /usr/local/share/mp3blaster) for more  information.  An  example
	      which  recodes the Russian win1251 charset to the	koi8-r charset
	      is included.

       DownFrequency (boolean)
	      If true, downsample audio	output to 22Khz	instead	of 44Khz (nec-
	      essary  on  some	ancient	 soundcards, like genuine Soundblaster
	      Pro's)

       File.ID3Names (boolean)
	      If enabled, the display mode in the file manager will show mp3's
	      by  their	 ID3-tag  by  default, instead of their	filename. (de-
	      fault: disabled)	(TODO:	Make  this  directive  a  string  with
	      printf-like format for the id3tag	fields).

       File.SortMode (string)
	      Determines  the  default file sorting mode for the file manager.
	      Valid modes are: alpha (default),	alpha-case,  modify-new,  mod-
	      ify-old, size-small, size-big, none.

       HideOtherFiles (boolean)
	      If  enabled,  non-audio/playlist	files will not be shown	in the
	      file manager.

       MixerDevice (string)
	      Mixer device to use for mixing (default: /dev/mixer).

       PlaylistDir (string)
	      Directory	  path	 where	 playlists   are   stored    (default:
	      ~/.mp3blaster_playlists)

       PlaylistMatching	(list of strings)
	      List  of	file  patterns (in regexp format) that determine which
	      files are	considered playlists (default:	all  files  ending  on
	      .lst/.m3u). Syntax identical to that of AudiofileMatching.

       ScanMP3 (boolean)
	      If  set, it will read each mp3 file before playing, to calculate
	      VBR total	time. This might be impractical	if mp3's are  streamed
	      over  a slow network connection, because the entire file will be
	      read. Scanning is	unnecessary if the mp3 has  a  so-called  XING
	      header  (which  most  VBR	 mp3's have, nowadays).	 Default: dis-
	      abled.

       SelectItems.UnselectFirst (boolean)
	      When selecting files from	the filemanager	or playlist using 'Se-
	      lect  some  items',  unselect previously selected	items prior to
	      selecting	matching new ones if this  option  is  set.  (default:
	      disabled)

       SelectItems.SearchRegex (boolean)
	      If  set,	use extended regular expression	to match files instead
	      of using the global (fnmatch-style) matching. This  is  for  the
	      'Select some items' feature.  (default: disabled)

       SelectItems.SearchCaseInsensitive (boolean)
	      If  set,	search case-insensitive	when using 'Select some	items'
	      feature. (default: enabled)

       SkipLength (number)
	      How many seconds to skip when forwarding or  rewinding  a	 song.
	      Default is 10.  Change to	your liking.

       PanSize (number)
	      Number  of  characters  to  pan  content to the left or right in
	      scrollable window.  Default = 5. Range is	1..40.

       WrapAround (boolean)
	      If disabled, the scrollable window will not wrap around when you
	      use attempt to go	past the upper or lower	boundary using the ar-
	      row keys.	(default: enabled)

       SoundDevice (string)
	      Sound device to use for audio output (default /dev/dsp (/dev/au-
	      dio on OpenBSD)).

       Threads (number,	range 50..500)
	      Amount  of threads to use	for buffering. More threads means more
	      buffering	(thus better hiccup prevention)

       WarnDelay (number, obsolete)
	      Time before a warning popup will	disappear.  Currently  not  in
	      use.
