\section{\label{ref:PlaybackOptions}Playback}
The \setting{Playback} sub menu allows you to configure settings
related to audio playback.
\begin{description}
\item[Shuffle. ]Alters how Rockbox will select which song to play next.\\
Options: \setting{Yes}/\setting{No}.
%
\item[Repeat. ]Configures settings related to repeating of directories or
playlists.\\
Options: \setting{Off} / \setting{All} / \setting{One} / \setting{Shuffle}
\nopt{ondiosp,ondiofm}{\setting{/A-B}}:
\begin{description}
%
\item[Off. ]The current playlist will not repeat when it is finished.
\note{If you have the \setting{Auto change directory} option set to
\setting{Yes}, Rockbox will move on to the next directory on your
hard drive. If the \setting{Auto Change Directory} option is set to
\setting{No}, playback will stop when the current directory or
playlist is finished.}
%
\item[All. ]The current playlist will repeat when it is finished.
\note{This option does \emph{not} shuffle all files on your \dap.
Rockbox is playlist oriented. When you play a song, a directory, or
an album, Rockbox creates a playlist and plays it. Thus, to shuffle
all songs on the \dap, you need to create a playlist of all songs on
the player, and play that playlist with shuffle mode set to
\setting{All}.}
%
\item[One. ]Repeat one track over and over.
%
\item[Shuffle. ]When the current playlist has finished playing, it will
be shuffled and then repeated.
%
\nopt{ondiosp,ondiofm}{
\item[A-B. ]Repeats between two user defined points within a track,
typically used by musicians when attempting to learn a piece of music.
This option is more complicated to use than the others as the \dap\
must first be placed into A-B repeat mode and then the start and end
points defined.\\

\item[Play Selected First. ]This setting controls what happens when you
select a file for playback while shuffle mode is on. If the
\setting{Play Selected First} setting is \setting{Yes}, the file you
selected will be played first. If this setting is \setting{No}, a random
file in the directory will be played first.
\item[Fast-Forward/Rewind. ]How fast you want search (fast forward or rewind)
to accelerate when you hold down the button. \setting{Off} means no
acceleration. \setting{2x/1s} means double the search speed once every
second the button is held. \setting{2x/5s} means double the search speed
once every 5 seconds the button is held.
\item[Anti-Skip Buffer. ]This setting allows you to control how much music is
stored in the \daps{} memory whilst playing a song, acting as a buffer
against shock or playback problems. The \dap{} transfers the selected
amount of the forthcoming song into its memory at high speed whilst you are
playing the song. It keeps a ``rolling'' buffer, which keeps feeding more
of the forthcoming song into memory as it goes along.
If the \dap{} is knocked, shaken or jogged heavily while Rockbox is trying
to read the hard drive, Rockbox might not be able to read the drive.
Rockbox will retry over and over again until it succeeds, but may
eventually reach the end of the memory buffer. When that happens, Rockbox
must stop playing and wait for more data from the disk, which causes your
music to skip. The anti-skip setting tells Rockbox how much extra buffer
memory to spare to handle this situation. This setting therefore allows you
to reduce the chances of there being a gap or pause during playback of
songs.
\nopt{ondio}{
\opt{MASCODEC}{The anti-skip buffer can be set to a value between 0 and 7
seconds.}
}%
\opt{ondio}{
The anti-skip buffer can safely be kept at zero. It will eventually be
eliminated.
}%
\opt{SWCODEC}{The anti-skip buffer can be set to various values between
5 seconds and 10 minutes.}%
\note{Having a large anti-skip buffer tends to use more power, and may
reduce your battery life. It is recommended to always use the lowest
possible setting that allows correct and continuous playback.}
\item[Fade on Stop/Pause. ]Enables and disables a fade effect when you
pause or stop playing a song. If the Fade on Stop/Pause option is
set to \setting{Yes}, your music will fade out when you stop or pause
playback, and fade in when you resume playback.
\item[Party Mode. ]Enables unstoppable music playback. When new songs are
selected, they are queued at the end of the current dynamic playlist
instead of being played immediately. Pausing and stopping playback is
disabled as well as skipping songs and launching plugins.
\opt{SWCODEC}{
\item[Crossfade. ]
This setting enables a cross-fader. At the end of a song, the song will
fade out as the next song fades in, creating a smooth transition between
songs.\\
Options:
\begin{description}
\item[Enable Crossfade. ]If set to \setting{Off}, crossfade is disabled.
If set to \setting{Always}, songs will always crossfade into one
another. If set to \setting{Shuffle}, crossfade is enabled when the
shuffle feature is set to \setting{Yes}, but disabled otherwise. If set
to track skip only, tracks will only crossfade when you manually change
tracks.
%
\item[Fade In Delay. ]The ``fade in delay'' is the length of time between
when the crossfade process begins and when the new track begins to fade
in.
%
\item[Fade In Duration. ]The length of time, in seconds, that it takes
your music to fade in.
%
\item[Fade Out Delay. ]The ``fade out delay'' is the length of time
between when the crossfade process begins and when the old track begins
to fade out.
%
\item[Fade Out Duration. ]The length of time, in seconds, that it takes
your music to fade out.
%
\item[Fade Out Mode. ]If set to \setting{Crossfade}, one song will fade
out and the next song will simultaneously fade in. If set to
\setting{Mix}, the ending song will continue to play as normal until
its end, while the starting song will fade in from under it.
\setting{Mix} mode is not
used for manual track skips, even if it is selected here.
\end{description}
\note{The crossfade setting is particularly effective when the player is
set on shuffle.}

\opt{SWCODEC}{
\item[Replaygain. ]This allows you to control the replaygain function.
The purpose of replaygain is to adjust the volume of the music played
so that all songs (or albums, depending on your settings) have the
same apparent volume. This prevents sudden changes in volume when
changing between songs recorded at different volume levels.
For replaygain to work, the songs must have been processed by a program
that adds replaygain information to the ID3 tags (or Vorbis tags).
\note{APEv2 tags are not currently supported.}
Options for replaygain are:
\begin{description}
\item[Enable Replaygain. ]This turns on/off the replaygain function.
%
\item[Prevent Clipping. ]Avoid clipping of a song's waveform.
If a song would clip during playback, the volume is lowered for
that song. Replaygain information is needed for this to work.
%
\item[Replaygain type. ]Choose the type of replaygain to apply:
\begin{description}
\item[Album Gain. ]Maintain a constant volume level between
albums, but keep any intentional volume variations between
songs in an album. (If album gain value is not available,
uses track gain information).
%
\item[Track Gain. ]Maintain a constant volume level between
tracks. If track gain value is not available, no replaygain
is applied.
%
\item[Track Gain if Shuffling. ]Maintains a constant volume
between tracks if \setting{Shuffle} is set to \setting{Yes}.
Reverts to album mode if \setting{Shuffle} is set to \setting{No}.
\end{description}
%
\item[Pre-amp. ]This allows you to adjust the volume when replaygain
is applied. Replaygain often lowers the volume, sometimes quite
much, so here you can compensate for that. Please note that a
(large) positive pre-amp setting can cause clipping, unless
prevent clipping is enabled. The pre-amp can be set to any
decibel (dB) value between -12dB and +12dB, in increments of 0.1{}dB.
\end{description}
}
\opt{SWCODEC}{
\item[Beep Volume. ]Controls the volume of the beep that is heard when
skipping forward or backward between tracks. The beep is disabled when
set to \setting{Off}.
}
\item[Auto-Change Directory. ]Control what Rockbox does when it reaches the end
of a directory. If \setting{Auto-Change Directory} is set to \setting{Yes},
Rockbox will continue to the next directory. If
\setting{Auto-Change Directory} is set to \setting{No}, playback will stop at
the end of the current playlist.
\note{You must have the \setting{Repeat} option set to \setting{No} for
\setting{Auto-Change Directory} to function properly.}
%
\opt{ipodnano,ipodvideo,ipodmini,ipod4g,ipod3g,ipodcolor,gigabeatf}{
\item[Pause on headphone unplug.] Enables and disables automatic pausing of
playback when the headphones are disconnected from the \daps{} headphone
socket.
%
\begin{description}
\item[Pause on headphone unplug. ]Options for automatic pause:
\begin{description}
\item[Off.] Disables automatic pause.
%
\item[Pause.] Pauses the \dap{} when the headphones are removed.
%
\item[Pause and Resume.] Pauses when the headphones are removed, and
resumes playback when they are reconnected.
\end{description}
\item[Duration to rewind.] Number of seconds (between 0 and 15) to rewind
playback when the headphones are removed.
%
\item[Disable auto-resume if phones not present.] This option will disable
the automatic resumption of playback at startup if the headphones are not
connected to the \dap{}.
\note{This requires \setting{Resume on Startup} to be enabled.}
\end{description}

\item[Last.fm Log.]\index{Last.fm Log}\index{Audioscrobbler|see{Last.fm Log}}
Enables logging of your played tracks for submittal to
\url{http://www.last.fm}. This service was formely known as
\emph{Audioscrobbler}. When you enable this option, you'll have to reboot to
start the logging. The log-file is called
\opt{CONFIG_RTC}{\fname{.scrobbler.log},}%
\nopt{CONFIG_RTC}{\fname{.scrobbler-timeless.log},}%
and is to be found in the root directory of your \dap{}.
\note{See \wikilink{LastFMLog} for a further description, and for tools you
can use to submit your Last.fm log.}
\item[Cuesheet Support.]\index{Cuesheet Support}
Enables reading of cuesheet files for played tracks. If a cuesheet is found
for a track, track markers are displayed on the progressbar and it is
possible to skip between the tracks within the cuesheet. Also the information
found in the cuesheet file will replace the information from the ID3 tags.
When you enable this option, you'll have to reboot for it to come into
effect.
