  \subsection{\label{ref:peak_meter}Peak Meter}
  The peak meter can be displayed on the While Playing Screen and consists of
  several indicators.  For a picture of the peak meter, please see the  While
  Recording Screen on page \pageref{ref:Whilerecordingscreen}.
  
  \begin{description}
  \item [The bar:]
    This is the wide horizontal bar. It represents the current volume value.
  \item [The peak indicator:]
    This is a little vertical line at the rightend of the bar. It indicates the
    peak volume value that occurred recently.
  \item [The clip indicator:]
    This is a little black block that is displayed at the very right of the
    scale when an overflow occurs. It usually doesn't show up during normal
    playback unless you play an audio file that is distorted heavily. If you
    encounter clipping while recording your recording will sound distorted. You
    should lower the gain. Note that the clip detection is not very precise.
    Clipping might occur without being indicated.
  \item [The scale:]
    Between the indicators of the right and left channel there are little dots.
    These dots represent important volume values. In linear mode each dot is a
    10\% mark. In dbfs mode the dots represent the following values (from right
    to left): 0db, {}-3db, {}-6db, {}-9db, {}-12db, {}-18db, {}-24db, {}-30db,
    {}-40db, {}-50db, {}-60db.

These include the ID3 Viewer and the pitch screen.}

This screen is accessible from the WPS screen, and provides a detailed view of
all the identity information about the current track. This info is known as
meta data and is stored in audio file formats to keep information on artist,
album etc. To access this screen, \opt{h1xx,h300}{hold \ButtonSelect\ to

  Rockbox handles function buttons in a different way to the Archos software.
  \ButtonFOne\ is always bound to the menu function, while \ButtonFTwo\ and
  \ButtonFThree\ enable two quick menus.
  
  \ButtonFTwo\ displays some browse and play settings which are likely to be
  changed frequently. This settings are Shuffle mode, Repeat mode and the Show
  files options
  
  Shuffle mode plays each track in the currently playing list in a random order
  rather than in the order shown in the browser.

  Repeat mode repeats either a single track (One) or the entire playlist (All).

  Show files determines what type files can be seen in the browser.  This can be
  just MP3 files and directories (Music), Playlists, MP3 files and directories
  (Playlists), any files that Rockbox supports (Supported) or all files on the
  disk (All).

  See page \pageref{ref:PlaybackOptions} for more information about these
  settings.

  \begin{table}
      \begin{btnmap}{}{}
        \ButtonLeft & Controls Shuffle mode setting \\
        \ButtonRight & Controls Repeat mode setting \\
        \ButtonDown & Controls Show file setting \\
      \end{btnmap}
  \end{table}
  
  \ButtonFThree\ controls frequently used display options.
  
  Scroll bar turns the display of the Scroll bar on the left of the screen on
  or off.
  
  Status bar turns the status display at the top of the screen on or off. Upside
  down inverts the screen so that the top of the display appears nearest to the
  buttons.  This is sometimes useful when storing the \dap\ in a pocket.  Key
  assignments swap over with the display orientation where it is logical for
  them to do so.

  See page \pageref{ref:Displayoptions} for more information about these
  settings.
