The \setting{\label{ref:PlaybackSettings}Playback Settings} menu allows
you to configure settings related to audio playback.
\section{Shuffle}
Turning shuffle on will cause Rockbox to randomly re-order the
playlist. Thus, to shuffle all of the audio files on the player, you first
need to create a playlist containing all of them. For more information on
creating playlists refer to \reference{ref:working_with_playlists}.\\
Options: \setting{Yes}/\setting{No}.
%
\section{Repeat}
Configures settings related to repeating of directories or playlists.\\
Options: \setting{Off} / \setting{All} / \setting{One} / \setting{Shuffle} /
\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.
%
\item[One]Repeat one track over and over.
%
\item[Shuffle]When the current playlist has finished playing, it will
be shuffled and then repeated.
%
\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.\\
\opt{RECORDER_PAD,IRIVER_H100_PAD,IRIVER_H300_PAD,IRIVER_H10_PAD,MROBE100_PAD%
,GIGABEAT_PAD,GIGABEAT_S_PAD,SANSA_E200_PAD,SANSA_C200_PAD}{%
To set the Start Point (A) press \ActionWpsAbSetAPrevDir{}.
Setting the End Point (B) is done accordingly using
\ActionWpsAbSetBNextDir{}. To reset the markers press \ActionWpsAbReset{}.
}%
\opt{ipod,IAUDIO_X5_PAD,ONDIO_PAD,PLAYER_PAD}{%
To set the Start Point (A) press \ActionWpsBrowse{}. The following
press of \ActionWpsBrowse{} will set the End Point (B), and a third
successive \ActionWpsBrowse{} will reset the markers.
}%
\end{description}
\section{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.
\section{Fast-Forward/Rewind}
These settings control the speed and acceleration during fast forward and rewind.
The setting \setting{FF/RW Min Step} controls the initial speed and \setting{FF/RW Accel} controls the acceleration.
\opt{disk_storage}{
\section{Anti-Skip Buffer}
This setting controls how early Rockbox starts refilling the music buffer
from the hard drive when playing. A longer Anti-Skip Buffer helps prevent
skips in music playback if Rockbox has trouble reading from the disk.
This can happen if the \dap{} is knocked, shaken or jogged heavily while
Rockbox is trying to read the hard drive.
\opt{MASCODEC}{
The anti-skip buffer can be set to a value between 0 and 7
seconds.
}
\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.}
}
\section{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.
\section{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}{
\section{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. The crossfade setting is particularly effective when the player is
set on shuffle.\\
Options for crossfade settings are:
\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 once the \setting{Fade In Delay} has ended.
%
\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 once the \setting{Fade Out Delay} has ended.
%
\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 rules above apply except in the instance where
\setting{Fade Out Delay} plus \setting{Fade Out Duration} is less then
\setting{Fade In Delay} (which would create a gap in the audio). In this case,
the \setting{Fade In Delay} is reduced to eliminate the gap.}
The graphic below illustrates how the different settings work in practice.

\section{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}
\section{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}.
}%\opt{swcodec}
\opt{spdif_power}{
\section{Optical Output}
Enables or disables the optical S/PDIF output to
allow a digital connection to a suitable external decoder. To enable
optical output, set to \setting{Yes}
}
\section{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. Using the \setting{Random} feature requires
you to first generate a folder list via the Random Folder Advance Configuration
plugin (see \reference{ref:random_folder_advance_config}).
\note{You must have the \setting{Repeat} option set to \setting{No} for
\setting{Auto-Change Directory} to function properly.}
\note{This feature only works when songs have been played from the file
browser. Using it with the database may cause unexpected behavior.}
%
\opt{headphone_detection}{
\section{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}
}%
\section{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{rtc}{\fname{.scrobbler.log},}%
\nopt{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.}
\section{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.
\section{Skip Length}\index{Skip Length}
Designed to speed up navigation when listening to long audio tracks,
\setting{Skip Length} changes the behavior of
the \ActionWpsSkipPrev{} and \ActionWpsSkipNext{} buttons so that they skip
by a given time instead of skipping to a new track.
\section{Prevent Track Skipping}\index{Prevent Track Skipping}
If this option is enabled, the ability to manually skip tracks is disabled
in order to avoid accidental track skips. It does not prevent changing tracks
if a track ends, which can be achieved by combining this option with
\setting{Repeat} set to \setting{One}
