In this tutorial we are going to explain how to set up ncmpcpp and its amazing graphic equalizer. We currently run Arch Linux as OS, but the procedure is similar to all the others OS. First to all let’s install MPD, the music player daemon. We have already written a tutorial on how to do this on Raspberry Pi, but the procedure does not change. Just follow this article.

MPD

Now we have set up MPD, the music folder and MPC a minimal command line interface to MPD. We have now to update our MPD config file, it is located to /etc/mpd.conf, so first to all remove the current config file

$ sudo rm /etc/mpd.conf

Now you can create a new one and copy and paste this configuration file or just wget it. To create a new one type

$ sudo nano /etc/mpd.conf

and copy this code.
Note-well: this is just an example code, the parts that you should pay particular attention are highlighted in bold.
BTW You can edit it as you like.

# An example configuration file for MPD
# See the mpd.conf man page for a more detailed description of each parameter.
# Files and directories #######################################################
#
# This setting controls the top directory which MPD will search to discover the
# available audio files and add them to the daemon's online database. This
# setting defaults to the XDG directory, otherwise the music directory will be
# be disabled and audio files will only be accepted over ipc socket (using
# file:// protocol) or streaming files over an accepted protocol.
#
# Set your music directory
music_directory "/home/ingandrea/music"
#
# This setting sets the MPD internal playlist directory. The purpose of this
# directory is storage for playlists created by MPD. The server will use
# playlist files not created by the server but only if they are in the MPD
# format. This setting defaults to playlist saving being disabled.
#
playlist_directory "/var/lib/mpd/playlists"
#
# This setting sets the location of the MPD database. This file is used to
# load the database at server start up and store the database while the
# server is not up. This setting defaults to disabled which will allow
# MPD to accept files over ipc socket (using file:// protocol) or streaming
# files over an accepted protocol.
#
db_file "/var/lib/mpd/mpd.db"
#
# These settings are the locations for the daemon log files for the daemon.
# These logs are great for troubleshooting, depending on your log_level
# settings.
#
# The special value "syslog" makes MPD use the local syslog daemon. This
# setting defaults to logging to syslog, otherwise logging is disabled.
#
#log_file "~/.mpd/log"
#
# This setting sets the location of the file which stores the process ID
# for use of mpd --kill and some init scripts. This setting is disabled by
# default and the pid file will not be stored.
#
pid_file "/tmp/mpd.pid"
#
# This setting sets the location of the file which contains information about
# most variables to get MPD back into the same general shape it was in before
# it was brought down. This setting is disabled by default and the server
# state will be reset on server start up.
#
state_file "/var/lib/mpd/mpdstate"
#
# The location of the sticker database. This is a database which
# manages dynamic information attached to songs.
#
#sticker_file "~/.mpd/sticker.sql"
#
###############################################################################

# General music daemon options ################################################
#
# This setting specifies the user that MPD will run as. MPD should never run as
# root and you may use this setting to make MPD change its user ID after
# initialization. This setting is disabled by default and MPD is run as the
# current user.
#
#Set your user
user "ingandrea"
#user "mpd"
#
# This setting specifies the group that MPD will run as. If not specified
# primary group of user specified with "user" setting will be used (if set).
# This is useful if MPD needs to be a member of group such as "audio" to
# have permission to use sound card.
#
#group "users"
#
# This setting sets the address for the daemon to listen on. Careful attention
# should be paid if this is assigned to anything other then the default, any.
# This setting can deny access to control of the daemon.
#
# For network
bind_to_address "127.0.0.1"
#
# And for Unix Socket
#bind_to_address "~/.mpd/socket"
#
# This setting is the TCP port that is desired for the daemon to get assigned
# to.
#
#port "6600"
#
# This setting controls the type of information which is logged. Available
# setting arguments are "default", "secure" or "verbose". The "verbose" setting
# argument is recommended for troubleshooting, though can quickly stretch
# available resources on limited hardware storage.
#
#log_level "default"
#
# If you have a problem with your MP3s ending abruptly it is recommended that
# you set this argument to "no" to attempt to fix the problem. If this solves
# the problem, it is highly recommended to fix the MP3 files with vbrfix
# (available from <http://www.willwap.co.uk/Programs/vbrfix.php>), at which
# point gapless MP3 playback can be enabled.
#
#gapless_mp3_playback "yes"
#
# Setting "restore_paused" to "yes" puts MPD into pause mode instead
# of starting playback after startup.
#
#restore_paused "no"
#
# This setting enables MPD to create playlists in a format usable by other
# music players.
#
#save_absolute_paths_in_playlists "no"
#
# This setting defines a list of tag types that will be extracted during the
# audio file discovery process. The complete list of possible values can be
# found in the mpd.conf man page.
#metadata_to_use "artist,album,title,track,name,genre,date,composer,performer,disc"
#
# This setting enables automatic update of MPD's database when files in
# music_directory are changed.
#
#auto_update "yes"
#
# Limit the depth of the directories being watched, 0 means only watch
# the music directory itself. There is no limit by default.
#
#auto_update_depth "3"

###############################################################################
# Normalization automatic volume adjustments ##################################
#
# This setting specifies the type of ReplayGain to use. This setting can have
# the argument "off", "album", "track" or "auto". "auto" is a special mode that
# chooses between "track" and "album" depending on the current state of
# random playback. If random playback is enabled then "track" mode is used.
# See <http://www.replaygain.org> for more details about ReplayGain.
# This setting is off by default.
#
#replaygain "album"
#
# This setting sets the pre-amp used for files that have ReplayGain tags. By
# default this setting is disabled.
#
#replaygain_preamp "0"
#
# This setting sets the pre-amp used for files that do NOT have ReplayGain tags.
# By default this setting is disabled.
#
#replaygain_missing_preamp "0"
#
# This setting enables or disables ReplayGain limiting.
# MPD calculates actual amplification based on the ReplayGain tags
# and replaygain_preamp / replaygain_missing_preamp setting.
# If replaygain_limit is enabled MPD will never amplify audio signal
# above its original level. If replaygain_limit is disabled such amplification
# might occur. By default this setting is enabled.
#
#replaygain_limit "yes"
#
# This setting enables on-the-fly normalization volume adjustment. This will
# result in the volume of all playing audio to be adjusted so the output has
# equal "loudness". This setting is disabled by default.
#
#volume_normalization "no"
#
###############################################################################
# MPD Internal Buffering ######################################################
#
# This setting adjusts the size of internal decoded audio buffering. Changing
# this may have undesired effects. Don't change this if you don't know what you
# are doing.
#
#audio_buffer_size "2048"
#
# This setting controls the percentage of the buffer which is filled before
# beginning to play. Increasing this reduces the chance of audio file skipping,
# at the cost of increased time prior to audio playback.
#
#buffer_before_play "10%"
#
###############################################################################
# Resource Limitations ########################################################
#
# These settings are various limitations to prevent MPD from using too many
# resources. Generally, these settings should be minimized to prevent security
# risks, depending on the operating resources.
#
#connection_timeout "60"
#max_connections "10"
#max_playlist_length "16384"
#max_command_list_size "2048"

###############################################################################
# Client TCP keep alive #######################################################
#
# For clients connected by TCP on supported platforms.
# Allows detection of dangling connections due to clients disappearing from
# the network without closing their connections.
#
# This is not usually necessary but can be useful in cases such as wifi connectected
# clients that go in and out of network range or turn off wifi without closing their
# connections. Combined with low max_connections this can soon cause clients to not
# be able to connect.
#
#
# Enable tcp keepalive on new client connections (default is "no")
#
#tcp_keep_alive "no"
#
# Time in seconds since the last communication on the connection and before
# the keepalive probing is started. (default is 7200 seconds)
#tcp_keep_alive_idle "7200"
#
# Interval in seconds between keepalive probes, once a probe started.
# (default is 75 seconds)
#tcp_keep_alive_interval "75"
#
# Number of failed probes before the connection is pronounced dead and
# the connection is closed. (default is 9 times)
#tcp_keep_alive_count "9"

###############################################################################
# Character Encoding ##########################################################
#
# If file or directory names do not display correctly for your locale then you
# may need to modify this setting.
#
#filesystem_charset "UTF-8"
#
# This setting controls the encoding that ID3v1 tags should be converted from.

To wget it

$ cd /etc/
$ sudo wget http://www.cmprogrammers.com/script/mpd.conf

To start the MPD service run

$ sudo systemctl start mpd.service

To enable the service at boot run

$ sudo systemctl enable mpd.service

In this way MPD will start on your device start up. If you want to run MPD as user create the directory ~/.mpd/ and a new config file.

$ mkdir .mpd

then just copy the config file in /etc/

$sudo cp /etc/mpd.conf ~/.mpd/

You have then to update the database of the daemon, so run

$ mpc update

Ncmpcpp

Now we are ready to install ncmpcpp. To enable the graphic equalizer we have to install ncmpcpp-git from AUR.

$ yaourt -S ncmpcpp-git

Once completed we can find a simple configuration file here /usr/share/doc/ncmpcpp/config but we have to crete a new one to enable the equalizer. Maybe it will be created once you have installed it, but if this did not happened we have to create it. The directory is ~/.ncmpcpp/ on our home so we can run it as user.

$ cd .ncmpcpp

Create the config file

$ sudo nano config

and copy and past the following code

% egrep -v '^#' .ncmpcpp/config
mpd_music_dir = "/home/ingandrea/Musica/GTA/"
visualizer_in_stereo = "yes"
visualizer_fifo_path = "/tmp/mpd.fifo"
visualizer_output_name = "my_fifo"
visualizer_sync_interval = "10"
visualizer_type = "spectrum"
visualizer_look = "◆▋"
message_delay_time = "3"
playlist_shorten_total_times = "yes"
playlist_display_mode = "columns"
browser_display_mode = "columns"
search_engine_display_mode = "columns"
playlist_editor_display_mode = "columns"
autocenter_mode = "yes"

state_line_color = "yellow"
state_flags_color = "red"
progressbar_color = "yellow"
statusbar_color = "cyan"
visualizer_color = "red"
mpd_host = "127.0.0.1"
mpd_port = "6600"
mouse_list_scroll_whole_page = "yes"
lines_scrolled = "1"
enable_window_title = "yes"
song_columns_list_format = "(25)[cyan]{a} (40)[]{f} (30)[red]{b} (7f)[green]{l}"

Or just wget it

$ sudo wget http://www.cmprogrammers.com/script/config




Start ncmpcpp

$ ncmpcpp

You will see this simple interface that show you all your song

image

Here we are, just select a song and play it. To visualize the equalizer press “8”.

image

You can choose to visualize it as spectrum or wave. If you want to change, you have to edit the ncmpcpp config file.

Spectrum

visualizer_type= “spectrum”

image

Wave

visualizer_type= “wave”

Have fun!
