mp3blaster - An interactive text-console based mp3 player.
- 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.
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 requiring bulky
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.
Downsample audio to 22Khz (necessary on some ancient soundcards, but it can
also be used to use less CPU time)
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
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
feeature should be changed so it won't require root privileges. Only install it suid root if you trust all local users!!!!.
Use <file> as config-file instead of ~/.mp3blasterrc
- --debug, -d
Log debug-info in $HOME/.mp3blaster (use this when sending bugreports!)
- --status-file, -f
Write info on the mp3's being played to the specified file.
Gets you this nice list of command-line parameters.
Set the mixer device to use (default = /dev/mixer). For NAS audio mixing,
use 'NAS'. (NOTE: NAS support doesn't work in version 3.0 or above yet)
- --no-mixer, -n
Don't start the built-in mixer.
Default playing mode is resp. Play first group only, Play all groups, Play
all songs in random order.
Dont't quit after playing all command-line supplied mp3's (only makes sense
in combination with --autolist or files from command-line)
Number or frames to decode in one loop. Range: 1 to 10 (default=5).
On slow machines, a lower number might improve reaction time of the interface,
but it's quite unlikely this will have any effect from version 3.0 on)
Select the audio device you wish to use for sound playback (default /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)
Numbers of threads to use for buffering. Range is 0..500 in increments of 50.
0 threads means no buffering (thus no hickup prevention).
Displays mp3blaster's version number.
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
- 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 keybindings 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 mp3blater is in (see section PROGRAM MODES).
If you're editing the playlist, the playlist is shown. In file manager mode,
you will see the directory 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 compact, 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
- Playlist Editor
By default, mp3blaster starts with the playlist editor. All keybindings
specific to playlist editing are listed in the keybindings 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 independantly. To shuffle all songs
in 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 'F9'. If you start and stop playing songs using F9, all information
about which song has already been played is lost. If you want to stop playback
to continue later, pause the current song or use the start and stop buttons.
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 enter 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 highlighting this song (either in
playlist mode or file manager mode) and pressing enter. When the song is
finished, the playlist continues 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 automatically 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 selected 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 distinctly 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 possible in all program modes. Keybindings specific to
playback are always listed in the keybindins window.
The order in which files are played in the playlist is determined by 2
settings: The global playback mode (displayed in the info window), and
each group's independant 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 enabled, 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 support: It
ignores the group structure totally, and simply shuffles all songs in a
completely random order.
You can store many settings and keybindings in a config file. By default,
mp3blaster will look for ~/.mp3blasterrc, unless you specify another 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 litteral
backslash, escape it with another backslash (\). Keywords are case-sensitive.
There are a few types of values: numbers, booleans, keybindings, colours,
and everything else is a string. The syntax of these types are:
Numerical values, in decimal notation.
yes/no, 1/0, or true/false (case-insensitive)
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).
One of: black, red, green, yellow, blue, magenta, cyan, white
These keywords are currently supported:
- 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 (necessary 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. (default: disabled)
(TODO: Make this directive a string with printf-like format for the id3tag
- File.SortMode (string)
Determines the default file sorting mode for the file manager. Valid modes
are: alpha (default), alpha-case, modify-new,
modify-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).
- SelectItems.UnselectFirst (boolean)
When selecting files from the filemanager or playlist using 'Select 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.
- 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 arrow keys. (default: enabled)
- SoundDevice (string)
Sound device to use for audio output (default /dev/dsp (/dev/audio on OpenBSD)).
- Threads (number, range 50..500)
Amount of threads to use for buffering. More threads means more buffering
(thus better hickup prevention)
- WarnDelay (number, obsolete)
Time before a warning popup will disappear. Currently not in use.
