\subsection{Split Editor}
2
-
\fixme{This chapter has to be rewritten, to fit in the multi-platform latex
3
-
source code that we currently use}
4
When recording an mp3 file, it is common practice to start the recording
5
a little bit early and stop it a little bit late to ensure all the
6
-
desired sound is recorded. This results in recordings that contains
7
extra snippets of sound in the beginning and the end. Unfortunately these
8
snippets can not be deleted easily because they are stored in the same
9
file as the desired recording. The purpose of the split editor is to
10
-
split a mp3 file (the input file) at a point in time (split point). Two
11
new files can be generated from the input file. The first file contains
12
the part before the split point and the second file contains the part
13
after the split point. Once this process has been successful the
14
-
original file can be deleted or kept as a backup.
15
-
16
-
The whole process of splitting a mp3 file consists of three steps:
17
-
18
-
\begin{enumerate}
19
-
\item defining the split point
20
-
\item generating the result files.
21
-
\item if desired delete the input file (with the browser, not the split
22
-
editor)
23
-
\end{enumerate}
24
-
25
-
\subsubsection{How to use the Split Editor}
26
-
27
-
\begin{itemize}
28
-
\item \textbf{Pause near the split point}
29
-
When the device plays the song just hit the PAUSE button, when playback
30
-
has roughly reached the split point. This need not be very precise as
31
-
the split point can be fine tuned later.
32
-
\item \textbf{Open the split editor}
33
-
34
-
Open the plugin. A screen similar to the one below will appear.

The Split Editor

-

-
{\centering\upshape
44
-
Here is an explanation of the areas marked in red on the screenshot.
45
-
\par}
46
-
47
-
\begin{enumerate}
48
-
\item The waveform \newline
49
-
\newline
50
-
The waveform displays the volume of the song over time. It will appear
51
-
as the song plays and help to visually identify the point in time where
52
-
the split is desired
53
-
\item The split point indicator\newline
54
-
\newline
55
-
The split point indicator is a vertical line with a small triangle at
56
-
the top end. It is the most important control element of the split
57
-
editor. It can be moved with the LEFT and RIGHT buttons. Later, when
58
-
you have fine tuned the split point, the song will be split at this
59
-
position.
60
-
\item The split time\newline
61
-
\newline
62
-
At the top of the window a time value is displayed. This is the point in
63
-
time within the song at which the split point indicator is positioned.
64
-
\item The locator\newline
65
-
\newline
66
-
Another vertical bar represents the position locator. It moves along as
67
-
the song plays. In contrast to the split point indicator it has no
68
-
triangles at the ends.
69
-
\item The time bar\newline
70
-
\newline
71
-
The time bar displays the current position within the song relative to
72
-
the whole song. The entire length of the time bar represents the song
73
-
length. The length of the solid part of the time bar represents the position and length
74
-
of the displayed part of the song.
75
-
\item The scale mode\newline
76
-
\newline
77
-
Directly above the F3 button the scale mode is displayed. The waveform
78
-
can be scaled either logarithmically or linearly. In logarithmic scale
79
-
mode the letters ``dB'' are displayed, in linear mode ``\%''. Use F3 to
80
-
switch between these modes. Linear mode usually gives better optical
81
-
hints with commercially recorded music. For quiet recordings,
82
-
especially of human speech, the logarithmic scale often is preferable.
83
-
\item The loop mode \newline
84
-
\newline
85
-
Directly above the F2 button the loop mode icon is displayed. There are
86
-
4 different loop modes. Pressing F2 changes to the next loop mode.

167
The values in the waveform are scaled according to the settings of the
168

peak meter. These can be altered in the menu
169
-
\textbf{General Settings {}-{\textgreater} Display{}-{\textgreater} Peak Meter}. If extreme minimum /
170
maximum values are set the waveform might be cut off. A minimum
171
setting of {}-60 dB and a maximum setting of 0 dB are recommended.
172
These settings should be capable of producing useful waveforms for very
···
174
sounds (such as commercial rock or pop music) switching to the linear
175
scale may prove more effective since the logarithmic scale compresses
176
loud noises and makes it more difficult to identify characteristic

shapes. Note that it is always possible to toggle the scale with F3.
