SYNOPSIS

alsaplayer [options] [ filename ...]

DESCRIPTION

This manual page documents briefly the alsaplayer command. This manual page was written for the Debian GNU/Linux distribution because the original program does not have a manual page.

alsaplayer is a generic music player that can play back a large amount of file formats.

If files are specified on the command line, these files are played. Otherwise alsaplayer plays its playlist from its last run, if any.

FILENAME

Play the specified file(s). Can be a file or an URL.

CD.cdda

Special filename. Play a CD. /dev/cdrom will be used by default. Otherwise, AlsaPlayer will use the device specified in your config file (usually ~/.alsaplayer/config).

OPTIONS

These programs follow the usual GNU command line syntax, with long options starting with two dashes (`-'). A summary of options is included below.

-c, --config <file>

Use the given config file for this session.

-h, --help

Print this help message.

-i, --interface <interface>

Use the specified interface instead of the default one.

-I, --script <file>

Specify the script to pass to the interface plugin.

-l, --startvolume <vol>

Start with this volume [default=1.0].

-p, --path <path>

Set the path alsaplayer looks for add-ons.

-q, --quiet

Quiet operation, no output.

-s, --session-name name

Name this session "name"

-v, --version

Print version of this program.

--verbose

Be verbose about the output.

--nosave

Do not save playlist content at exit.

Player control:

-n, --session #

Select session # [default=0]

-e, --enqueue file(s)

Enqueue file(s) in a running alsaplayer.

-E, --replace file(s)

Clears and queues file(s) in a running alsaplayer.

--status

Get some information about the session.

--volume #

Set software volume [0.0-1.0].

--start

Start playing.

--stop

Stop playing.

--pause

Pause/unpause playing.

--prev

Jump to the previous track.

--next

Jump to the next track.

--seek <second>

Jump to the specified second in the current track.

--relative <second>

Jump <second> seconds from current position.

--speed <value>

Set the playback speed with -10 <= <value> <= 10. 1.0 = normal speed, -1.0 = normal speed backwards. Be aware that alsaplayer respect your LOCALE. That implies that the decimal point will vary accordingly. I.e., with french LOCALE, a valid speed value is 1,5 and not 1.5.

--jump #

Jump to the specified playlist track.

--clear

Clear the whole playlist

--quit

Quit the session.

Sound driver options:

-d, --device string

Select the specific device for the output plugin. For the ALSA plugin, the default is "default". For the JACK plugin, the default is "alsa_pcm:playback_1,alsa_pcm:playback_2".

-f, --fragsize #

Set fragment size in bytes [default=4096].

-F, --frequency #

Set the output frequency [default=44100].

-g, --fragcount #

Fragment count [default=8].

-r, --realtime

Enable realtime scheduling. To use this as a normal user, alsaplayer must be SUID root.

-o, --output [alsa|esound|jack|nas|null|oss|sgi|sparc]

Use the specified output driver.

Experimental options:

-S,--loopsong

Loop the file.

-P,--looplist

Loop the playlist.

-x,--crossfade

Crossfade playlist entries.

JACK OUTPUT PLUGIN

For use with JACK, -F <sample_rate> is mandatory for best results. The value of sample rate must be the same as the one used by jackd.

If you forget the -F parameter, the sound can be very bad. The only remedy at that time is to restart both jackd and AlsaPlayer.

DAEMON INTERFACE

With the daemon interface, it is mandatory to add the -s option. You must process in two steps to get sound with it. First launch the daemon:

alsaplayer -i daemon -s <name>

and then add some song:

alsaplayer -e <some.song>

GTK+ INTERFACE

The gtk+ interface provide some basic keyboard controls:

v

Stop

x

Play

c

Pause

b

Next Song

z

Previous Song

g

Seek Forward

a

Seek Backward

f

Forward Play

s

Reverse Play

t

Speed Up one musical semitone. (handy for changing the key the song is played back in)

q

Speed Down one musical semitone.

h

Speed Up one comma. (handy to tune the song instead of the guitar when playing at the same time as listening)

i

Speed Down one comma.

r

Volume Up

w

Volume Down

l

Loop
