This results in recordings that contain +extra snippets of sound and the beginning and end. Unfortunately these +snippets can not be deleted easily because they are stored in the same +file as the desired recording. The purpose of the split editor is to +split a mp3 file (the input file) at a point in time (split point). Two +new files can be generated from the input file. The first file contains +the part before the split point and the second file contains the part +after the split point. Once this process has been successful the +original file can be deleted or kept as a backup. + +The whole process of splitting a mp3 file consists of three steps: + +\begin{enumerate} +\item defining the split point +\item generating the result files. +\item if desired delete the input file (with the browser, not the split +editor) +\end{enumerate} + +\subsubsection{How to use the Split Editor} + +\begin{itemize} +\item \textbf{Pause near the split point} +When the device plays the song just hit the PAUSE button, when playback +has roughly reached the split point. This need not be very precise as +the split point can be fine tuned later. +\item \textbf{Open the split editor} + +Open the plugin. A screen similar to the one below will appear. + +{\centering\itshape + [Warning: Image ignored] % Unhandled or unsupported graphics: +%\includegraphics[width=3.701cm,height=2.11cm]{images/rockbox-manual-img67.gif} + \newline +The Split Editor +\par} + +{\centering\upshape +Here is an explanation of the areas marked in red on the screenshot. +\par} + +\begin{enumerate} +\item The waveform \newline +\newline +The waveform displays the volume of the song over time. It will appear +as the song plays and help to visually identify the point in time where +the split is desired +\item The split point indicator\newline +\newline +The split point indicator is a vertical line with a small triangle at +the top end. It is the most important control element of the split +editor. It can be moved with the LEFT and RIGHT buttons. Later, when +you have fine tuned the split point, the song will be split at this +position. +\item The split time\newline +\newline +At the top of the window a time value is displayed. This is the point in +time within the song at which the split point indicator is positioned. +\item The locator\newline +\newline +Another vertical bar represents the position locator. It moves along as +the song plays. In contrast to the split point indicator it has no +triangles at the ends. +\item The time bar\newline +\newline +The time bar displays the current position within the song relative to +the whole song. The entire length of the time bar represents the song +length. The length of the solid part of the time bar represents the position and length +of the displayed part of the song. +\item The scale mode\newline +\newline +Directly above the F3 button the scale mode is displayed. The waveform +can be scaled either logarithmically or linearly. In logarithmic scale +mode the letters ``dB'' are displayed, in linear mode ``\%''. Use F3 to +switch between these modes. Linear mode usually gives better optical +hints with commercially recorded music. For quiet recordings, +especially of human speech, the logarithmic scale often is preferable. +\item The loop mode \newline +\newline +Directly above the F2 button the loop mode icon is displayed. There are +4 different loop modes. Pressing F2 changes to the next loop mode. + +\begin{itemize} +\item [Warning: Image ignored] % Unhandled or unsupported graphics: +%\includegraphics[width=0.794cm,height=0.476cm]{images/rockbox-manual-img68.gif} + Playback loops around the split point indicator. This mode is best +used when searching and zooming for the desired point at which to split +the recording. +\item [Warning: Image ignored] % Unhandled or unsupported graphics: +%\includegraphics[width=0.794cm,height=0.476cm]{images/rockbox-manual-img69.gif} + Playback loops from the split point indicator to the end of the +visible area.

This mode is +best used when playing the song outside of the borders of the displayed +region. +\end{itemize} + +\item Perform the split \newline +\newline +The icon directly above the F1 button indicates its function to execute +the split. When split positioning is complete open the save dialogue with F1. +\end{enumerate} + +{\bfseries +Controls in the split editor } +\end{itemize} + +\begin{tabular}[c]{|p{2.975cm}|p{3.047cm}|p{6.649cm}|} +\hline +{\centering\bfseries\itshape +Recorder +\par} +& +{\centering\bfseries\itshape +Ondio +\par} +& +{\centering\bfseries\itshape +Function +\par} +\\\hline +{\centering +Off +\par} +& +{\centering +On/Off +\par} +& +Quit plugin +\\\hline +{\centering +Left/Right +\par} +& +{\centering +Left/Right +\par} +& +Move the split point indicator +\\\hline +{\centering +Up/Down +\par} +& +{\centering +Up/Down +\par} +& +Zoom in / out +\\\hline +{\centering +Play +\par} +& +{\centering +Mode +\par} +& +Play from the split position +\\\hline +{\centering +F1 +\par} +& +{\centering +Mode+Left +\par} +& +Enter the save dialogue +\\\hline +{\centering +F2 +\par} +& +{\centering +Mode+Up +\par} +& +Toggle loop modes +\\\hline +{\centering +F3 +\par} +& +{\centering +Mode+Right +\par} +& +Toggle logarithmic / linear scaling +\\\hline +{\centering +On+Left +\par} +& +{\centering +~ +\par} +& +Play half speed +\\\hline +{\centering +On+Right +\par} +& +{\centering +~ +\par} +& +Play 150\% speed +\\\hline +{\centering +On+Play +\par} +& +{\centering +~ +\par} +& +Play normal speed +\\\hline +\end{tabular} + +\subsubsection{Save the files} +In the save dialogue it is possible to specify which of the files you +want to save and their names.

These can be altered in the menu +\textbf{General Settings {}-{\textgreater} Display{}-{\textgreater} Peak Meter}. If extreme minimum / +maximum values are set the waveform might be cut off. A minimum +setting of {}-60 dB and a maximum setting of 0 dB are recommended. +These settings should be capable of producing useful waveforms for very +soft sounds in logarithmic mode (dB). When the editor is used on loud +sounds (such as commercial rock or pop music) switching to the linear +scale may prove more effective since the logarithmic scale compresses +loud noises and makes it more difficult to identify characteristic +shapes. Note that it is always possible to toggle the scale with F3. + + |
