|
|
|
|
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.

|
|
\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.

\\\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}
|
|
|
|
\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.
|
