NAME

       mpd.conf - Music Player Daemon configuration file

DESCRIPTION

       mpd.conf is the configuration file for mpd(1).  If not specified on the
       command  line,  MPD  first  searches  for  it  at  ~/.mpdconf  then  at
       ~/.mpd/mpd.conf and then in /etc/mpd.conf.

       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 {
               parameter1 "value"
               parameter2 "value"
       }

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

       See  docs/mpdconf.example  in  the  source  tarball  for   an   example
       configuration file.

REQUIRED PARAMETERS

       follow_outside_symlinks <yes or no>
              Control  if  MPD will follow symbolic links pointing outside the
              music dir.  You must recreate the database after  changing  this
              option.  The default is "yes".

       follow_inside_symlinks <yes or no>
              Control  if  MPD  will follow symbolic links pointing inside the
              music dir, potentially adding duplicates to the  database.   You
              must  recreate  the  database  after  changing this option.  The
              default is "yes".

       db_file <file>
              This specifies where the db file will be stored.

       sticker_file <file>
              The location of the sticker database.  This is a database  which
              manages dynamic information attached to songs.

       log_file <file>
              This  specifies  where  the  log  file  should  be located.  The
              special value "syslog" makes MPD use the local syslog daemon.

OPTIONAL PARAMETERS

       pid_file <file>
              This specifies the file to save mpd's process ID in.

       music_directory <directory>
              This specifies the directory where music is located.  If you  do
              not configure this, you can only play streams.

       playlist_directory <directory>
              This  specifies  the directory where saved playlists are stored.
              If you do not configure this, you cannot save playlists.

       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).

       user <username>
              This specifies the user that MPD  will  run  as,  if  set.   MPD
              should  never  run  as root, and you may use this option to make
              MPD change its user id after initialization.  Do  not  use  this
              option if you start MPD as an unprivileged user.

       bind_to_address <ip address or hostname or any>
              This  specifies  which  address  mpd  binds  to  and listens on.
              Multiple  bind_to_address  parameters  may  be  specified.   The
              default is "any", which binds to all available addresses.

              To  bind to a Unix domain socket, specify an absolute path.  For
              a system-wide MPD, we suggest the path "/var/run/mpd/socket".

       port <port>
              This specifies the port that mpd listens  on.   The  default  is
              6600.

       log_level <default, secure, or verbose>
              This  specifies  how  verbose  logs  are.   "default" is minimal
              logging, "secure" reports from  what  address  a  connection  is
              opened,  and  when it is closed, and "verbose" records excessive
              amounts of information for debugging purposes.  The  default  is
              "default".

       zeroconf_enabled <yes or no>
              If  yes,  and  MPD  has  been compiled with support for Avahi or
              Bonjour, service information will be  published  with  Zeroconf.
              The default is yes.

       zeroconf_name <name>
              If  Zeroconf  is  enabled,  this is the service name to publish.
              This name should be unique  to  your  local  network,  but  name
              collisions  will  be properly dealt with.  The default is "Music
              Player".

       password <password@permissions>
              This specifies a password for access  to  mpd.   The  format  is
              "password@permissions"  where  permissions  is a comma delimited
              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.  An example value
              is "somePassword@read,add".  Multiple password parameters may be
              specified.

       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 the "password" config parameter.
              If   no   passwords    are    specified,    the    default    is
              "read,add,control,admin", otherwise it is "" (no permissions).

       audio_output
              See DESCRIPTION and the various AUDIO OUTPUT PARAMETERS sections
              for  the  format  of  this  parameter.   Multiple   audio_output
              sections  may  be  specified.   If  no  audio_output  section is
              specified, then MPD will scan for a usable audio output.

       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.

       samplerate_converter <integer or prefix>
              This specifies the libsamplerate converter to use.  The supplied
              value should either be an integer or a prefix of the name  of  a
              converter.  The default is "Fastest Sinc Interpolator".

              At  the  time  of  this  writing,  the  following converters are
              available:

              Best Sinc Interpolator (0)

                     Band limited sinc interpolation, best quality, 97dB  SNR,
                     96% BW.

              Medium Sinc Interpolator (1)

                     Band  limited  sinc  interpolation,  medium quality, 97dB
                     SNR, 90% BW.

              Fastest Sinc Interpolator (2)

                     Band limited sinc interpolation, fastest, 97dB  SNR,  80%
                     BW.

              ZOH Interpolator (3)

                     Zero  order  hold  interpolator,  very  fast,  very  poor
                     quality with audible distortions.

              Linear Interpolator (4)

                     Linear interpolator, very fast, poor quality.

              internal

                     Poor quality, no floating point operations.  This is  the
                     default  (and  only  choice)  if MPD was compiled without
                     libsamplerate.

              For an up-to-date list of available converters, please  see  the
              libsamplerate     documentation     (available     online     at
              <http://www.mega-nerd.com/SRC/>).

       mixer_type <alsa, oss, software, hardware or disabled>
              This specifies which mixer to use.  The default is hardware  and
              depends on what audio output support mpd was built with. Options
              alsa and oss are legacy and should not be used in  new  configs,
              but when set mixer_device and mixer_control will apply.

       mixer_device <mixer dev>
              This  specifies  which  mixer  to  use.   The default for oss is
              "/dev/mixer"; the default for alsa  is  "default".  This  global
              option  is  deprecated  and  should  not  be  used.  Look at the
              mixer_device option of corresponding output device instead.

       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". This global option is deprecated and should not
              be used. Look  at  the  mixer_control  option  of  corresponding
              output device instead.

       replaygain <album or track>
              If  specified,  mpd will adjust the volume of songs played using
              ReplayGain  tags  (see  <http://www.replaygain.org/>).   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.

       replaygain_preamp <-15 to 15>
              This is the gain (in dB) applied to songs with ReplayGain  tags.

       volume_normalization <yes or no>
              If  yes,  mpd  will  normalize the volume of songs as they play.
              The default is no.

       audio_buffer_size <size in KiB>
              This specifies the size of the audio buffer in  kibibytes.   The
              default  is  2048,  large  enough  for  nearly 12 seconds of CD-
              quality audio.

       buffer_before_play <0-100%>
              This specifies how much of the audio  buffer  should  be  filled
              before playing a song.  Try increasing this if you hear skipping
              when manually changing songs.  The default is 10%, a little over
              1 second of CD-quality audio with the default buffer size.

       http_proxy_host <hostname>
              This  setting  is  deprecated.   Use  the "proxy" setting in the
              "curl" input block.  See MPD user manual for details.

       connection_timeout <seconds>
              If a client does not send any new data in this time period,  the
              connection is closed.  The default is 60.

       max_connections <number>
              This  specifies  the  maximum  number  of  clients  that  can be
              connected to mpd.  The default is 5.

       max_playlist_length <number>
              This specifies the maximum number of songs that can  be  in  the
              playlist.  The default is 4096.

       max_command_list_size <size in KiB>
              This  specifies  the  maximum  size  a command list can be.  The
              default is 2048.

       max_output_buffer_size <size in KiB>
              This specifies the maximum  size  of  the  output  buffer  to  a
              client.  The default is 8192.

       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.

       id3v1_encoding <charset>
              This specifies the character set which ID3v1  tags  are  encoded
              in.   A  list  of  supported  character  sets can be obtained by
              running "iconv -l".  The default is  to  let  libid3tag  convert
              them  (from  ISO-8859-1,  as  the  standard specifies) and do no
              additional conversion.

       gapless_mp3_playback <yes or no>
              This specifies whether to support gapless playback of MP3s which
              have  the  necessary  headers.  Useful if your MP3s have headers
              with incorrect information.  If you have such MP3s, it is highly
              recommended  that  you  fix  them  using  vbrfix (available from
              <http://www.willwap.co.uk/Programs/vbrfix.php>)    instead    of
              disabling  gapless  MP3  playback.   The  default  is to support
              gapless MP3 playback.

       save_absolute_paths_in_playlists <yes or no>
              This specifies whether  relative  or  absolute  paths  for  song
              filenames  are used when saving playlists.  The default is "no".

       metadata_to_use <tags>
              This specifies the tag types that will be scanned for  and  made
              available  to clients.  Note that you must recreate (not update)
              your database for changes to  this  parameter  to  take  effect.
              Possible  values  are  artist, album, title, track, name, genre,
              date, composer, performer, comment, and disc.  Multiple tags may
              be  specified  as  a  comma separated list.  An example value is
              "artist,album,title,track".  The special  value  "none"  may  be
              used  alone  to disable all metadata.  The default is to use all
              known tag types except for comments.

REQUIRED AUDIO OUTPUT PARAMETERS

       type <type>
              This specifies the audio output type.  See the list of supported
              outputs in mpd --version for possible values.

       name <name>
              This specifies a unique name for the audio output.

OPTIONAL AUDIO OUTPUT PARAMETERS

       format <sample_rate:bits:channels>
              This  specifies  the sample rate, bits per sample, and number of
              channels of audio that is sent to the audio output device.   See
              documentation  for  the  audio_output_format  parameter for more
              details.  The default is to use whatever audio format is  passed
              to the audio output.

OPTIONAL ALSA OUTPUT PARAMETERS

       device <dev>
              This  specifies the device to use for audio output.  The default
              is "default".

       mixer_device <mixer dev>
              This specifies which mixer to use.  The  default  is  "default".
              To use the second sound card in a system, use "hw:1".

       mixer_control <mixer ctrl>
              This specifies which mixer control to use (sometimes referred to
              as the "device").  The default is "PCM".  Use "amixer scontrols"
              to see the list of possible controls.

       mixer_index <mixer index>
              A number identifying the index of the named mixer control.  This
              is probably only useful if your alsa device has  more  than  one
              identically-named  mixer  control.   The  default  is  "0".  Use
              "amixer scontrols" to  see  the  list  of  controls  with  their
              indexes.

       use_mmap <yes or no>
              Setting  this  allows  you  to  use  memory-mapped I/O.  Certain
              hardware setups may benefit from this, but most  do  not.   Most
              users  do  not  need  to  set  this.   The default is to not use
              memory-mapped I/O.

       auto_resample <yes or no>
              Setting this to "no" disables ALSA's software resampling, if the
              hardware does not support a specific sample rate.  This lets MPD
              do the resampling.  "yes" is the  default  and  allows  ALSA  to
              resample.

       auto_channels <yes or no>
              Setting  this to "no" disables ALSA's channel conversion, if the
              hardware  does  not  support  a  specific  number  of  channels.
              Default: "yes".

       auto_format <yes or no>
              Setting  this  to "no" disables ALSA's sample format conversion,
              if the hardware does  not  support  a  specific  sample  format.
              Default: "yes".

       buffer_time <time in microseconds>
              This   sets   the  length  of  the  hardware  sample  buffer  in
              microseconds.  Increasing it may help  to  reduce  or  eliminate
              skipping  on  certain  setups.  Most users do not need to change
              this.  The default is 500000 microseconds (0.5 seconds).

       period_time <time in microseconds>
              This  sets  the  time  between  hardware  sample  transfers   in
              microseconds.   Increasing  this  can  reduce  CPU  usage  while
              lowering it can  reduce  underrun  errors  on  bandwidth-limited
              devices.  Some users have reported good results with this set to
              50000, but not all devices support values this high.  Most users
              do  not  need  to  change  this.   The  default  is  256000000 /
              sample_rate(kHz), or 5804 microseconds for CD-quality audio.

OPTIONAL OSS OUTPUT PARAMETERS

       device <dev>
              This specifies the device to use for audio output.  The  default
              is "/dev/dsp".

       mixer_device <mixer dev>
              This specifies which mixer to use.  The default is "/dev/mixer".

       mixer_control <mixer ctrl>
              This specifies which mixer control to use (sometimes referred to
              as the "device").  The default is to use the main PCM mixer.  An
              example is "Pcm".

OPTIONAL PULSE OUTPUT PARAMETERS

       server <server list>
              A space separated list of servers to try  to  connect  to.   See
              <http://www.pulseaudio.org/wiki/ServerStrings> for more details.
              The default is to  let  PulseAudio  choose  a  server.   If  you
              specify  more  than one server name, MPD tries to connect to one
              after another until it successfully establishes a connection.

       sink <sink>
              The sink to output to.  The default is to let PulseAudio  choose
              a sink.

REQUIRED JACK OUTPUT PARAMETERS

       name <name>
              The  client  name  to  use  when connecting to JACK.  The output
              ports <name>:left and <name>:right will also be created for  the
              left and right channels, respectively.

OPTIONAL JACK OUTPUT PARAMETERS

       ports <left_port,right_port>
              This  specifies  the  left and right ports to connect to for the
              left and right channels, respectively.  The default  is  to  let
              JACK choose a pair of ports.

       ringbuffer_size <size in bytes>
              This specifies the size of the ringbuffer in bytes.  The default
              is 32768.

OPTIONAL AO OUTPUT PARAMETERS

       driver <driver>
              This specifies  the  libao  driver  to  use  for  audio  output.
              Possible values depend on what libao drivers are available.  See
              <http://www.xiph.org/ao/doc/drivers.html>  for  information   on
              some  commonly  used  drivers.  Typical values for Linux include
              "oss" and "alsa09".  The  default  is  "default",  which  causes
              libao to select an appropriate plugin.

       options <opts>
              This specifies the options to use for the selected libao driver.
              For oss, the only option available is "dsp".   For  alsa09,  the
              available  options  are:  "dev", "buf_size", and "periods".  See
              <http://www.xiph.org/ao/doc/drivers.html> for available  options
              for some commonly used drivers.  Options are assigned using "=",
              and ";" is used  to  separate  options.   An  example  for  oss:
              "dsp=/dev/dsp".         An       example       for       alsa09:
              "dev=hw:0,0;buf_size=4096".  The default is "".

       write_size <size in bytes>
              This specifies how many bytes to write to the  audio  device  at
              once.   This parameter is to work around a bug in older versions
              of libao on sound cards with very small buffers.  The default is
              1024.

REQUIRED FIFO OUTPUT PARAMETERS

       path <path>
              This  specifies  the  path of the FIFO to output to.  Must be an
              absolute path.  If the path does not exist it  will  be  created
              when  mpd is started, and removed when mpd is stopped.  The FIFO
              will be created with the same user and group as mpd  is  running
              as.   Default  permissions  can be modified by using the builtin
              shell  command  "umask".   If  a  FIFO  already  exists  at  the
              specified  path  it will be reused, and will not be removed when
              mpd is stopped.  You can use  the  "mkfifo"  command  to  create
              this, and then you may modify the permissions to your liking.

REQUIRED SHOUT OUTPUT PARAMETERS

       name <name>
              This  specifies  not only the unique audio output name, but also
              the stream title.

       host <hostname>
              This specifies the hostname of the icecast server to connect to.

       port <port>
              This specifies the port of the icecast server to connect to.

       mount <mountpoint>
              This specifies the icecast mountpoint to use.

       password <password>
              This  specifies  the  password  to  use  when  logging in to the
              icecast server.

       quality <quality>
              This specifies the encoding quality to use.  The value  must  be
              between   0  and  10.   Fractional  values,  such  as  2.5,  are
              permitted.  Either the quality or the bitrate parameter must  be
              specified,  but  not  both.   For  Ogg,  a higher quality number
              produces  higher  quality  output.   For  MP3,  it's  just   the
              opposite, with lower numbers producing higher quality output.

       bitrate <kbps>
              This  specifies  the  bitrate  to  use for encoding.  Either the
              quality or the bitrate parameter  must  be  specified,  but  not
              both.

       format <sample_rate:bits:channels>
              This  specifies  the sample rate, bits per sample, and number of
              channels to use for encoding.

OPTIONAL SHOUT OUTPUT PARAMETERS

       encoding <encoding>
              This specifies which output encoding to use.  Should  be  either
              "ogg"  or  "mp3",   "mp3" is needed for shoutcast streaming. The
              default is "ogg".

       protocol <protocol>
              This specifies the protocol that wil be used to connect  to  the
              icecast/shoutcast   server.   The   options   are   "shoutcast",
              "icecast1" and "icecast2". The default is "icecast2".

       user <username>
              This specifies the username  to  use  when  logging  in  to  the
              icecast server.  The default is "source".

       public <yes or no>
              This  specifies  whether to request that the stream be listed in
              all public stream directories  that  the  icecast  server  knows
              about.  The default is no.

       timeout <seconds>
              This specifies the number of seconds to wait before giving up on
              trying to connect to the  icecast  server.   The  default  is  2
              seconds.

       description <description>
              This specifies a description of the stream.

       genre <genre>
              This specifies the genre(s) of the stream.
