MOC – Music On Console , е конзолен аудио плеър за Linux/UNIX ,създаден ,за да бъде мощен и в същото време лесен за употреба. Интерфейсът му наподобява много на Midnight Commander.Възпроизвежда много формати,като се почне от mp3,Ogg Vorbis,FLAC и се стигне до Musepack,Speex,WAVE, AIFF, AU и редица други по-малко известни.Последната стабилна версия е 2.4.4.Официална страница на проекта – http://moc.daper.net.

.При новите версии на Дебиан базираните дистрибуции MOC е наличен в пакетният мениджър.Ако пакетът отсъства по някаква причина ,то той може да бъде добавен през хранилищата на Debian Sid ,като в /etc/apt/sources.list се добавят следните редове:

deb http://www.lxtec.de/debarchiv unstable main
deb-src http://www.lxtec.de/debarchiv unstable main

След това инсталацията протича по обичайния ред:

# apt-get update && apt-get install moc

Инсталацията също може да се извърши и от сорс ,като се свали желаната версия от секция Download на официалния сайт.
След като инсталацията приключи,плеърът се стратира от конзола с команда $ mocp.
Изгледът на програмата с настройки по дефолт е нещо приблизително такова:

Навигирането се осъществява чрез стрелките на клавиетурата.

Основни клавишни комбинации при работа с MOC

Тук се спирам само на най-основните клавишни комбинации,необходими при работата с плеъра

• Tab – прехвърля фокуса от лявия панел (директориите) в деснията панел (плейпистът)
• Enter – когато фокусът е в левия панел – влиза в маркирана директория
• Enter – когато фокусът е в десния панел – възпроизвежда маркирания аудио файл
• Q – спира възпрозвеждането и прекратява работата на плеъра(Изключва го)
• q – извежда конзола без да прекратява възпроизвеждането на плейлиста
• s – спира изпълнението на плейлиста ,без да извежда конзола
• < / > – усилва  / намаля звука ( с по 1%)
• Space – Пауза
• а – добавя маркираната в ляво папка като плейлист в дясно
• C – изчиства плейлиста ( без да прекратява възпроизвеждането на започнат вече файл)

Пълният списък с клавишните комбинации и команди на плеъра може да видите с H

Настройки

Настройките на MOC се осъществяват и са съхранени в конфигурационен файл config ,който се намира в директория .moc ,която от своя страна се намира в домашната директория , т.е  ~/.moc/config.Един примерен,но доста подробен и функционален файл за MOC изглежда така:

# This is a configuration file for the MOC player. It should be named 'config'
# and placed in directory ~/.moc/
# Comments begins with '#'.
# You can use quotes and escape ('\') in parameters

# Show file titles (title, author, album) instead of file names.

# SincMediumQuality - much faster
# SincFastest - the fastest bandlimited interpolation

#ForceSampleRate    = 48000

# By default even if the sound card reports that it can output 24bit samples
# MOC converts 24bit PCM to 16bit. This option set to yes allows MOC to use
# 24bit output (for example MP3 decoder uses this format). This is disabled
# in the default configuration because there were reports that it prevents
# from playing MP3 files on some soundcards.
#Allow24bitOutput    = no

# Use realtime priority for output buffer thread. This will prevent gaps while
# playing even with heavy load. The user which runs MOC must have permissions
# to set such a priority. This could be dangerous, because it is possible that
# a bug in MOC will freeze your computer.

# Main window layoutis can be configured. You can change the position and the
# size of the menus (directory and playlist). You have 3 layouts ant switch
# between then using the 'l' key (standard mapping). By default only 2 layouts
# are configured.
#
# The format is as folows:
# Each menu is described in format NAME:POSITION_X,POSITION_Y,WIDTH,HEIGHT
# NAME is directory or playlist
# Other parameters define position and size of the menu. They can be absolute
# numbers (like 10) or a percent value of the screen size (like 45%).
# WIDTH and HEIGHT can have value of FILL which means fill the screen from
# the menu's position to the border.
# Separate menu descriptions using a space.
# Menus may overlap.
# You must describe at least one menu (default is to fill the whole window).
# There must be at least one layout (Layout1) defined. Other can be empty ("").
#
# Examples:
#
# Just one layout, the directory will occupy the whole screen, the playlist
# will have 1/4 of the screen size and be positioned at lower right corner.
# Layout1 = "playlist:50%,50%,50%,50%"
# Layout2 = ""

# menu at the bottom. Playlist will occupy 10 lines and the directory menu
# the rest.

# %f - file path
# %i - title made from tags
#
# Data from tags:
# %t - title
# %a - album
# %r - artist
# %n - track
# %m - time of the file (in seconds)
#
# Parameters above applys to the currently selected file. If you change them to
# capital letters, they are taken from the currently played file.
#
# Programms are run using execv(), not a shell, so you can't do things like
# redirecting the output to a file. The command string is split using blank
# characters as separators, the first element is the command to be executed
# and the rest are parameters, so if you use "echo Playing: %i" we run program
# echo (from $PATH) with 2 parameters: 'Playing:' string and the title. Even
# if the title contains spaces it's still one parameter and it's safe if it
# contains `rm -rf /`.
#
# Examples:
# ExecCommand1        = "cp %f /mnt/usb_drive"
ExecCommand3 = "/home/frankie/now_playing %i"
ExecCommand2 = "/home/frankie/lyrics --artist %r --title %t"

Инсталация на теми

Инсталацията на теми в MOC е елементарна и се състои в набавянето на теми от интернет,и поставянето им в работната директория на програмата , в папка с име themes - ~/.moc/themes.За да може избраната тема да се зарежда по дефолт при всяко стартиране на прохрамата ,темата се описва в config файла,чрез името й.Само ще спомена ,че непосредствено след инсталацията на програмата на разположение на потребителя има налични няколко теми,които могат да се видят и пробват чрез T.С една „custom“ тема визията на MOC изглежда например така:

Интересни неща като скриптове , пачове и теми за програмата може да се намери на този адрес .
Естествено за допълнителна информация и помощ ,приложението си има и Форум .
