.TH mpd.conf 5
.SH NAME
mpd.conf \- Music Player Daemon configuration file
.SH DESCRIPTION
\fBmpd.conf\fP is the configuration file for mpd(1).  If not specified on the
command line, MPD first searches for it at \fB~/.mpdconf\fP and then in
\fB/etc/mpd.conf\fP.

Lines beginning with a "#" character are comments.  All other non-empty lines
specify parameters and their values.  These lines contain the parameter name
and parameter value (surrounded by double quotes) separated by whitespace
(either tabs or spaces).  For example:

parameter "value"

The exception to this rule is the audio_output parameter, which is of the form:

audio_output {
.br
        parameter1 "value"
        parameter2 "value"
.br
}

Parameters that take a file or directory as an argument should use absolute
paths.

See \fBdocs/mpdconf.example\fP in the source tarball for an example
configuration file.
.SH REQUIRED PARAMETERS
.TP
.B music_directory <directory>
This specifies the directory where music is located.
.TP
.B playlist_directory <directory>
This specifies the directory where saved playlists are stored.
.TP
.B db_file <file>
This specifies where the db file will be stored.
.TP

This specifies where the error file should be located.
.TP
.B pid_file <file>
This specifies the file to save mpd's process ID in.
.SH OPTIONAL PARAMETERS
.TP
.B state_file <file>
This specifies if a state file is used and where it is located.  The state of
mpd will be saved to this file when mpd is terminated by a TERM signal or by
the "kill" command.  When mpd is restarted, it will read the state file and
restore the state of mpd (including the playlist).
.TP
.B audio_output
See \fBREQUIRED AUDIO OUTPUT PARAMETERS\fP and \fBOPTIONAL AUDIO OUTPUT
PARAMETERS\fP.
.TP
.B audio_output_format <sample_rate:bits:channels>
This specifies the sample rate, bits per sample, and number of channels of
audio that is sent to each audio output.  Note that audio outputs may specify
their own audio format which will be used for actual output to the audio
device.  An example is "44100:16:2" for 44100Hz, 16 bits, and 2 channels.  The
default is to use the audio format of the input file.
.TP
.B mixer_type <oss, alsa or software>
This specifies which mixer to use.  The default depends on what audio output
support mpd was built with.
.TP
.B mixer_device <mixer dev>
This specifies which mixer to use.  The default for oss is "/dev/mixer"; the
default for alsa is "default".
.TP
.B mixer_control <mixer ctrl>
This specifies which mixer control to use (sometimes referred to as the
"device").  Examples of mixer controls are PCM, Line1, Master, etc.  An example
for OSS is "Pcm", and an example for alsa is "PCM".
.TP
.B filesystem_charset <charset>
This specifies the character set used for the filesystem.  A list of supported
character sets can be obtained by running "iconv -l".  The default is
determined from the locale when the db was originally created.
.TP
.B replaygain <album or track>
If specified, mpd will adjust the volume of songs played using replaygain tags
(see <\fBhttp://www.replaygain.org/\fP>).  Setting this to "album" will adjust
volume using the album's replaygain tags, while setting it to "track" will
adjust it using the track replaygain tags.  Currently only FLAC, Ogg Vorbis,
Musepack, and MP3 (through ID3v2 replaygain tags, not APEv2) are supported.

This specifies the size of the buffer used for playing HTTP streams.  The
default is 128.
.TP

.TP
.B port <port>
This specifies the port that mpd listens on.  The default is 6600.
.TP
.B password <password@permissions>
This specifies a password for access to mpd.  The format is
"password@permissions" where permissions is a comma delimmitted list composed
of "read", "add", "control", and/or "admin".  "read" allows for reading of the
database, displaying the current playlist, and current status of mpd.  "add"
allows for adding songs and loading playlists.  "control" allows for all other
player and playlist manipulations.  "admin" allows the db to be updated and for
the client to kill mpd.  More than one password can be specified.  An example
value is "somePassword@read,add".
.TP
.B default_permissions <permissions>
This specifies the permissions of a client that has not been authenticated
using a password.  The format of permissions is specified in the description of

track, name, genre, date, composer, performer, comment, and disc.  Multiple
tags may be specified as a comma separated list.  An example value is
