\section{\label{ref:PlaybackOptions}Playback Options}
The \setting{Playback Options} submenu allows you to configure settings
related to audio playback.
\begin{description}
\item[Shuffle: ]Alters how Rockbox will select which next song to play.\\
Options: \setting{On}/\setting{Off}.
%
\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 directory or 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 directory or 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 directory or playlist has finished
playing, it will be shuffled and then repeated.
%
\nopt{ondiosp,ondiofm}{
\item[A--B: ]Repeats between two user defined point within a track,
typically used by musicians when attempting to learn a piece of music.
This option is more complicated to use that the others as the \dap\
must first be placed into A--B repeat mode and then the start and end
points defined.\\
\fixme{
Hold Play and press Left --- Sets Start Point (A)\\
Hold Play and press Right --- Sets End Point (B)\\
}
}
\end{description}
\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[Resume: ]Rockbox can be configured to start playing automatically
when you turn on the \dap. If the resume function is set to start
automatically playing, Rockbox will start at the point where you last
turned off the \dap. The options for the \setting{Resume} function are:
\begin{description}
\item[Yes: ]Rockbox will unconditionally try to resume.
\item[No: ]Rockbox will not resume.
\emph{If resume is set to \setting{No}, Rockbox will start in the
\setting{File Browser}.}
\end{description}
\note{Earlier versions of Rockbox had an ``Ask'' setting, which would ask whether
to resume when the jukebox was turned on. This setting has been eliminated because it
was redundant. If resume is set to ``Yes'' pressing
\opt{PLAYER_PAD,RECORDER_PAD,IAUDIO_X5_PAD,IPOD_4G_PAD}{\fixme{FixMe}}
\opt{ONDIO_PAD}{\fixme{FixMe}}
\opt{IRIVER_H100_PAD,IRIVER_H300_PAD}{\ButtonOn}
on the \dap\ will resume from the point where the \dap\ was stopped before shutdown.
\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 \dap's 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.
\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.}
\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 added to the end of the current dynamic playlist
instead of being played immediately.
The \fixme{PLAY} and \fixme{STOP} buttons are disabled.
\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 (vorbis tags
respectively).
\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 shuffle mode is selected. Reverts to album
mode if shuffle is off.
\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}
}
}
\item[Auto Change Directory: ]Control what Rockbox does when it reaches the end
of a directory. If 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 directory.
\note{You must have the \setting{Repeat} option set to \setting{No} for \setting{Auto Change Directory}
to function properly.}
