Recorder main menu  Player main menu  
\par}

This is the screen from which the rest of the
Rockbox functions can be accessed.  It is used for a variety of
functions, which are detailed below. You can access the Rockbox main
menu by pressing MENU (player/studio version) or F1 (recorder version)
key. All options in Rockbox can be controlled via this menu. Some of
them can also be found in the Quick Menus (recorder version only).

All settings are persistently stored on the unit. However, Rockbox does
not spin up the disk solely for the purpose of saving settings, but
instead will save them when it spins up the disk the next time, for
example when refilling the MP3 buffer or navigating through the file
browser. Changes to settings may therefore not be saved unless the
Jukebox is shut down safely (see page \pageref{ref:Safeshutdown}).

The two settings menus are covered in detail starting on page \pageref{ref:Part4}.
 All the other options on the main menu are explained here.

Entering the ``Recording'' option in the Main menu launches the
recording application. The screen shows the time elapsed and the size
of the file being recorded. A peak meter is present to allow you set
Gain correctly.  The frequency, channels and quality settings are shown
on the last line.

\end{tabular}


\subsubsection{\label{ref:Recordingsettings}Recording Settings}
\begin{itemize}
\item \textbf{Quality}
Choose the quality here (0 to 7). Default is 5, best quality is 7,
smallest file size is 0.  This setting effects how much your sound
sample will be compressed.  Higher quality settings result in larger
MP3 files.

The quality setting is just a way of selecting an average bit rate, or
number of  bits per second, for a recording.  When  this setting is
lowered, recordings are compressed more (meaning worse sound quality),
and the average bitrate changes as follows.
\end{itemize}

\\\hline
\end{tabular}\end{center}

\begin{itemize}
\item \textbf{Frequency} 
Choose the recording frequency (sample rate) {}- 48kHz, 44.1kHz,
32kHz (MPEG version 1), and 24kHz, 22.05kHz, 16kHz (MPEG version 2) are
available.  Higher sample rates use up more disk space, but give better
sound quality.  This setting determines which frequency range can
accurately be reproduced during playback. Lower frequencies produce
smaller files, for two reasons.  The amount of data to be compressed is
smaller and the data is easier to compress, since higher frequencies
are not present.  The frequency setting also determines which version
of the MPEG standard sound is recorded using.

\item \textbf{Source}
Choose the source of the recording.  This can be microphone, line in, 
or SPDIF (digital). For recording from the radio on the FM recorder,
see page \pageref{ref:FMradio} below.

Note: you cannot change the sample rate for digital recordings.

\item \textbf{Channels}
This allows you to select mono or stereo recording.  Please note that
for mono recording, only the left channel is recorded.  Mono recordings
are usually somewhat smaller than stereo.

\item \textbf{Independent Frames}
The independent frames option tells the Jukebox to encode with the bit
reservoir disabled, so the frames are independent of each other. This
makes a file easier to edit.

\item \textbf{Time Split}
This option is useful when timing recordings. If set to active it stops
a recording at a given interval and then starts recording again with a
new file., which is useful for long term recordings.

The splits are seamless (frame accurate), no audio is lost at the split
point. The break between recordings is only the time required to stop
and restart the recording, on the order of 2{}-4 seconds.

Options (hours:minutes between splits): off, 24:00, 18:00, 12:00, 10:00,
8:00, 6:00, 4:00, 2:00, 1:20 (80 minute CD), 1:14 (74 minute  CD),
1:00, 00:30, 00:15, 00:10, 00:05.
\item \textbf{Prerecord Time}
This setting buffers a small amount of audio so that when the
record button is pressed, the recording will begin from that number of
seconds earlier.  This is useful for ensuring that a recording begins
before a cue that is being waited for.\\

Options: Off, 1{}-30 seconds
\end{itemize}

\end{itemize}

\section{\label{ref:Bookmarkconfig}\label{ref:Bookmarkmenu}Bookmarks}
The bookmarks menu allows you to create and manage bookmark files.

\begin{itemize}

\item \textbf{Create Bookmark}
While playing a track, use this option to save your current position
within the track so that you can return to it at a later time. 
Bookmarks are saved on a per folder basis i.e. all of the files in the
same folder have their bookmarks stored together. You can store
multiple bookmarks for the same track.

\item \textbf{List Bookmarks}

% Unhandled or unsupported graphics:
%\includegraphics[width=4.098cm,height=2.341cm]{images/rockbox-manual-img30.png}% Unhandled or unsupported graphics:
%\includegraphics[width=4.669cm,height=2.006cm]{images/rockbox-manual-img31.png} 
Recorder bookmark browser  Player bookmark browser  

While playing a track, use this option to return to any bookmark in the current folder.  The bookmark browser
screen (shown above) is now displayed.  Use the UP and DOWN keys
(recorder) or MINUS and PLUS keys (player) to navigate between
bookmarks.  Press PLAY to jump to a bookmark, ON+PLAY to delete a
bookmark or STOP/OFF to exit the browser.

\item \textbf {Recent bookmarks}
If the ``save a list of recently created bookmarks'' option is enabled
then you can view a list of several recent bookmarks here and select
one to jump straight to that track.  This option is off by default. 
See page \pageref{ref:Bookmarkconfigactual} for more details on
configuring bookmarking in Rockbox. 

\end{itemize}

\section{\label{ref:playlistoptions}Playlist Options}
This menu allows you to work with playlists. 
Playlists can either be created automatically by playing a file in
a directory directly, which will cause all of the files in that
directory to be placed in the playlist, or they can be created by hand
using the File Menu (see page \pageref{ref:Filemenu})
or using the Playlist Options menu.  Both  automatic and manually
created playlists can be edited using this menu.

\begin{itemize}
\item \textbf{Create Playlist}
Rockbox will create a playlist with all tracks in the current directory and all subdirectories. The playlist will be created one folder level ``up'' from
where you currently are. 

\item \textbf{View Current Playlist}
Displays the contents of the playlist currently stored in memory.

\item \textbf{Save Current Playlist}
Saves the current dynamic playlist, excluding queued tracks, to the
specified file. If no path is provided then playlist is saved to
current directory (see page \pageref{ref:Playlistsubmenu}).

\item \textbf{Recursively Insert Directories}
If set to ON then when you insert/queue a directory in Dynamic Playlist,
all subdirectories will also be inserted. If set to ASK then you are
prompted about recursive insertion when inserting a directory. 
\end{itemize}

\section{Browse Plugins}
With this option you can load and run various plugins that have been
written for Rockbox.\\

A detailed description of the different plugins begins on page \pageref{ref:Part5}.

\section{\label{ref:Info}Info}
This option shows MP3 ram buffer size, battery voltage level and
estimated time remaining, disk total space and disk free space.

On players use the MINUS and PLUS keys to step through several pages of
information.

\begin{itemize}

\item \textbf{Show ID3 info}
This is an alternative way to access the ID3 viewer.  See page
\pageref{ref:ID3viewer} for details on the ID3 viewer.

\item \textbf{Rockbox Info}
Displays some basic system information.  This is, from top to bottom,
the amount of memory Rockbox has available for storing music (the
buffer), battery status, hard disk size and the amount of free space on
the disk.

\item \textbf{Version}
Software version and credits display.

\item \textbf{Debug (Keep Out!)}
This submenu is intended to be used only by Rockbox developers. It shows
hardware, disk, battery status and a lot of other information.  It is
not recommended that users access this menu unless instructed to do so
in the course of fixing a problem with Rockbox.  In particular the
``Dump ROM Contents'', ``View/clear RTC RAM'' and
``Screenshot'' and ``Sound test'' functions
should be treated with care. 
\end{itemize}

\section{Shutdown (Player)}
This menu option saves the Rockbox configuration and turns off the hard
drive before shutting down the machine.  For maximum safety this
procedure is recommended when turning off the Jukebox.  (There is a
very small risk of hard disk corruption otherwise.) See page
\pageref{ref:Safeshutdown} for more details.
