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. All options in Rockbox can be controlled via this menu.
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 \dap\ is shut down safely (see page \pageref{ref:Safeshutdown}).
The two settings menus are covered in detail starting on page \pageref{ref:configure_rockbox}. 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. \opt{MASCODEC}{The frequency, channels and quality}\opt{SWCODEC}{The frequency and channels} settings are shown on the last line.
\ButtonFTwo& Quick menu for recording settings. A quick press will leave the screen up (press {\ButtonFTwo} again to exit),while holding it will close the screen when you release it. \\
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.
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. \opt{MASCODEC}{The frequency setting also determines which version of the MPEG standard sound is recorded using.}
Choose the source of the recording. This can be microphone, line in, or SPDIF (digital). \opt{CONFIG_TUNER}{For recording from the radio on the FM recorder, see page \pageref{ref:FMradio}.}
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.
The independent frames option tells the \dap 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.
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\\
\item\textbf{Directory}
Allows changing the location where the recorded files are saved.\\
Enter the name (maximum number of characters is 32).
\opt{IRIVER_H100_PAD,IRIVER_H300_PAD}{Press \ButtonOn\ to save.}
\opt{IAUDIO_X5_PAD}{Press FixMe to save.}
\item\textbf{Selecting a preset}\\
\opt{ONDIO_PAD,RECORDER_PAD}
{
Press \opt{RECORDER_PAD}{\ButtonFTwo}\opt{ONDIO_PAD}{(FixMe)} to go to the preset list. Use \ButtonUp\ and \ButtonDown\ to move the cursor and then press \opt{RECORDER_PAD}{\ButtonPlay}\opt{ONDIO_PAD}{(Insert Correct Key)} to select. Use \ButtonLeft\ to leave the preset without selecting anything.
Press \ButtonSelect\ to go to the preset list. Use \ButtonUp\ and \ButtonDown\ to move the cursor and then press \ButtonSelect\ to select. Use \ButtonLeft\ to leave the preset without selecting anything.
}
\item\textbf{Removing a preset}\\
\opt{ONDIO_PAD,RECORDER_PAD}{
Press \opt{RECORDER_PAD}{\ButtonFOne}\opt{ONDIO_PAD}{(Insert Correct Key)} to go to the menu, then select ``Remove preset''.
Press \ButtonSelect\ to go to the preset list. Use \ButtonUp\ and \ButtonDown\ to move the cursor and then Hold \ButtonSelect\ on the preset to that you wish to remove, then select "Remove preset."
}
\opt{RECORDER_PAD}{
\item\textbf{Recording}\\
Press \ButtonFThree\ to start recording the currently playing station. Press \ButtonOff\ to stop recording. Press \ButtonPlay\ again to seamlessly start recording to a new file. The settings for the recording can be changed in the \ButtonFOne\ menu before starting the recording. See page \pageref{ref:Recordingsettings} for details of recording settings.
}
Note: The radio will turn off when playing an MP3.
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.
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.
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.
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.
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.
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}).
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.
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.
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.
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.
