.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 This specifies the directory where music is located. .TP .B playlist_directory This specifies the directory where saved playlists are stored. .TP .B db_file This specifies where the db file will be stored. .TP .B log_file This specifies where the log file should be located. .TP .B error_file This specifies where the error file should be located. .SH OPTIONAL PARAMETERS .TP .B pid_file This specifies the file to save mpd's process ID in. .TP .B state_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 user This specifies the user that mpd will run as, if set. .TP .B bind_to_address 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. .TP .B port This specifies the port that mpd listens on. The default is 6600. .TP .B log_level 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". .TP .B zeroconf_enabled If yes, and MPD has been compiled with support for Avahi or Bonjour, service information will be published with Zeroconf. The default is yes. .TP .B zeroconf_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". .TP .B password 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. .TP .B default_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). .TP .B audio_output See \fBDESCRIPTION\fP and the various \fBAUDIO OUTPUT PARAMETERS\fP 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. .TP .B audio_output_format 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 samplerate_converter 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: .RS .TP Best Sinc Interpolator (0) Band limited sinc interpolation, best quality, 97dB SNR, 96% BW. .TP Medium Sinc Interpolator (1) Band limited sinc interpolation, medium quality, 97dB SNR, 90% BW. .TP Fastest Sinc Interpolator (2) Band limited sinc interpolation, fastest, 97dB SNR, 80% BW. .TP ZOH Interpolator (3) Zero order hold interpolator, very fast, very poor quality with audible distortions. .TP Linear Interpolator (4) Linear interpolator, very fast, poor quality. .RE .IP For an up-to-date list of available converters, please see the libsamplerate documentation (available online at <\fBhttp://www.mega-nerd.com/SRC/\fP>). .TP .B mixer_type This specifies which mixer to use. The default depends on what audio output support mpd was built with. .TP .B mixer_device This specifies which mixer to use. The default for oss is "/dev/mixer"; the default for alsa is "default". .TP .B mixer_control 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 replaygain 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. .TP .B replaygain_preamp <-15 to 15> This is the gain (in dB) applied to songs with ReplayGain tags. .TP .B volume_normalization If yes, mpd will normalize the volume of songs as they play. The default is no. .TP .B audio_buffer_size This specifies the size of the audio buffer in kibibytes. The default is 2048, large enough for nearly 12 seconds of CD-quality audio. .TP .B 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. .TP .B http_buffer_size This specifies the size of the buffer used for playing HTTP streams. The default is 128. .TP .B http_prebuffer_size This specifies how much of an HTTP stream should be buffered before beginning playback. The default is 32. .TP .B http_proxy_host Use to specify the proxy host used for HTTP connections. .TP .B http_proxy_port The port that the HTTP proxy host uses. .TP .B http_proxy_user If the HTTP proxy server requires authentication, this specifies the username. .TP .B http_proxy_password If the HTTP proxy server requires authentication, this specifies the password. .TP .B connection_timeout If a client does not send any new data in this time period, the connection is closed. The default is 60. .TP .B max_connections This specifies the maximum number of clients that can be connected to mpd. The default is 5. .TP .B max_playlist_length This specifies the maximum number of songs that can be in the playlist. The default is 4096. .TP .B max_command_list_size This specifies the maximum size a command list can be. The default is 2048. .TP .B max_output_buffer_size This specifies the maximum size of the output buffer to a client. The default is 8192. .TP .B filesystem_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 id3v1_encoding 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. .TP .B gapless_mp3_playback 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 ) instead of disabling gapless MP3 playback. The default is to support gapless MP3 playback. .TP .B save_absolute_paths_in_playlists This specifies whether relative or absolute paths for song filenames are used when saving playlists. The default is "no". .TP .B metadata_to_use 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. .SH REQUIRED AUDIO OUTPUT PARAMETERS .TP .B type This specifies the audio output type. See the list of supported outputs in mpd --version for possible values. .TP .B name This specifies a unique name for the audio output. .SH OPTIONAL AUDIO OUTPUT PARAMETERS .TP .B format 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 \fBaudio_output_format\fP parameter for more details. The default is to use whatever audio format is passed to the audio output. .SH OPTIONAL ALSA OUTPUT PARAMETERS .TP .B device This specifies the device to use for audio output. The default is "default". .TP .B use_mmap 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. .TP .B auto_resample 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. .TP .B auto_channels Setting this to "no" disables ALSA's channel conversion, if the hardware does not support a specific number of channels. Default: "yes". .TP .B auto_format Setting this to "no" disables ALSA's sample format conversion, if the hardware does not support a specific sample format. Default: "yes". .TP .B buffer_time
