alsaplayer - Online in the Cloud

PROGRAM:

NAME

alsaplayer - plays various sound files

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
