mp3DirectCut is a frame based editor for <b>MPEG audio</b> (Layers 2 and 3).
You can cut, copy, paste or change the volume <b>without re-encoding</b> anything of the file.
This makes mp3DirectCut very fast and prevents loss of audio quality. The program enables
<b>easiest navigation</b> even on large files and gives you a <b>visualisation</b> of the MP3
audio data. It can handle <b>Cue sheets</b> allowing to split a file at cue positions. And you can
also directly <b>record and encode</b> an MP3 from your audio input device.
</p>

<font size="4"><b><u>Basic settings</u></b></font>
</p><ul><ul><p>
At first to be able to playback files the program needs an MP2/3 decoder.
This can be either a system installed <b>MP3 ACM Codec</b> (XP should contain it by default)
or the <b>mpglib.dll</b> which needs to be in the program's or in Windows' folder.
The mpglib.dll (available at the homepage) makes mp3DirectCut more independent
(if you don't have an ACM) and supports Layer 2. But it takes more cpu than ACM.
</p><p>
Switch to your prefered decoder in the Devices settings (Settings => Configure => Devices).
In the Output device section you can select a Wave device and adjust the amount of
frames being decoded to each play buffer between 'fast' (1 frame) and 'reliable' (8 frames).
On slower machines set a higher value. For a fast response of the graphics select a lower value.
The default is 4.
</p><p>
The program <b>language</b> can be adjusted at the Operation Tab (Settings => Configure => Operation).
In the list select your language if present. The language files must be in a sub directory "Languages"
of the mp3DirectCut folder. If no language is selected or found, the program looks also into its own
folder for one (!) language file. So you can also enable your language without keeping the subfolder
(but then it does not appear in the list).
</p>
</ul></ul>
<a name="nav">
<br>
<p>
<font size="4"><b><u>Navigation</u></b></font>
</p><ul><ul><p>
As mp3DirectCut is designed to handle large files,
there are many ways to reach a position:
</p><p>
<b>Scrollbar</b><br>
With the slider you can move along a file.
The arrow buttons (or <b>keys:</b> Shift+Left/Right)
move a single MPEG frame backwards or forward.
</p><p>
<b>[<<<] [<<] [>>] [>>>]</b>
(or <b>keys:</b> Left/Right and Page up/down)<br>
These buttons are user definable.
You can set the amount of frames to skip back/forward
in the configuration window between 10 and 10.000 for
[<<<] and [>>>] and between 1 and 1.000 for [<<] [>>].
</p><p>
<b>Mouse</b><br>
You can directly jump to any file position by left clicking
into the map area below the audio graph.
</p><p>
<b>CTRL+Mouse</b><br>
If you hold down the CTRL key while clicking into the
audio graph the cursor jumps to the shown audio position.
</p><p>
<b>[I...<<] [>>...I]</b><br>
These buttons set the play cursor to the beginning or the end of the selection if present.
</p><p>
<b>List Menu and [I<] [>I]</b><br>
Let you choose the active edit point and set the play cursor to it's beginning.
</p><p>
<b>Position field</b><br>
You can enter a position by time or percentage into
the edit field and apply the value by pressing Enter or Tab.

<font size="4"><b><u>Audio editing</u></b></font>
</p><ul><ul><p>
Editing a file or compilation of file fragments means to create different <b>parts</b>
of audio content. Each time you cut, paste or set a cue one or more new parts will be
created.
</p><p>
Like in other editors, editing begins by making a <b>selection</b>.
A selection can be an audio <b>range</b> or only a single <b>position</b>.
Ranges can be used to cut, copy or paste. A position selection is for creating cues
or points of volume change.
</p><p>
</ul>
<b>Making a selection</b>
<ul>
</p><p>
You have one of these ways:
</p><p>
<b>Buttons [Set begin] and [Set end]</b><br>
These buttons set the beginning or the end of the selection to the current position.
</p><p>
<b>Mouse</b><br>
You can point/drag a selection by using the left and the right mouse button.
How the buttons behave can be set in the preferences:
<br>Method 1: Left button sets the beginning of the
selection (by clicking or dragging), the right button sets the end.
<br>Method 2: Left button makes a new selection and enlarges it.
The right button moves beginning or end (depending on which is nearer).
</p><p>
Note: to make a large selection you should at first point to one end of the selection
and then jump to where the other end should be and set it there.
It is not possible to drag a long selection by moving the mouse over the windows boarders.
</p><p>
<b>Selection field</b><br>
You can enter beginning, end or length of the selection
by numbers. Take care not to delete the symbols, otherwise
the values cannot be read from the field correctly.
</p><p>
</ul><b>Part structure</b><ul>
</p><p>
At each edit point begins an independent audio part. Parts can even be
from <b>different audio files</b>. Each part can have information about a <b>volume
change</b> or whether it is a <b>cue</b>.
</p><p>
If you <b>cut</b> a selection the range disappears and is not longer known by
the program. But an edit point remains at the cut position and you can <b>restore</b>
the cut range every time by using the edit button.
</p><p>
</ul><b>Buttons [Cut] and [Edit]</b><ul>
</p><p>
The <b>Cut</b> button splits the current audio part into two parts.
If there was a selection range it will be cut. If the selection
had a length of zero the Cut function only splits the part. The split point
can be used to create a volume change or a cue.
</p><p>
If a split point should work as a cue (needed e.g. for creating Cue sheets),
its <b>cue flag</b> must be set. The program sets it automatically on creating split points
or loading Cue sheets. Edit points with cue flag are shown as <b>dotted line</b>. To set
or remove a cue flag manually, press CTRL+Q or check/uncheck 'Cue' in the part
properties dialog (Edit menu).
</p><p>
With the <b>Edit</b> button you can remove existing edit points. This
means that two parts will be joined. If the edit point was a cut, the removed
audio range will be restored. <b>Note:</b> editing a point is not possible
if it was created by paste. In this case the audio data between two parts
is not continouus and there is nothing to restore. To remove such insertions
select them and use the function 'Remove selected elements' in the Edit menu.
</p><p>
</ul><b>Edit menu: Cut, Copy, Paste</b><ul>
</p><p>
While the Cut button does <b>not</b> copy the cut range to the clipboard
Cut and Copy from the Edit menu do. The copied information can be pasted
to any new position (current or selection). Copy and Paste can handle multiple files
and parts and work completely non-destructive. This means that no audio data
is copied but only access informations.
</p><p>
</ul><b>Volume changes</b><ul>
</p><p>
To change the volume simply create one or more edit points (from zero length selections).
Then you can directly change the gain by dragging the <b>gray grips</b>.
Alternatively the gain of the highlighted edit point can be changed by the keys <b>CTRL+Up/Down</b>
</p><p>
Audio ranges with a modified volume are shown in the color of edit points.
The gain sign of the edit point shows the volume change in dB.
Note: Volume change works only with Layer 3.
As the data remains encoded volume changes can only
be made in a resolution of 1.5 dB steps.
</p><p>
To create a fade or a silence for a selection you can use the <b>gain dialog</b> in the
Edit menu. A gain area can also be created by the <b>Normalize</b>
function in the Edit menu.
</p><p>
</ul><b>Change or remove existing edit points</b><ul>
</p><p>
First highlight a point by moving to its position (see 'Navigation' section).
After pressing <b>[Edit]</b> the cut range or the split point will become the
selection and will be deleted (!). So after changing positions you must hit <b>[Cut]</b> again.
More in the Edit button section above.
</p>
</ul></ul>
<a name="pre">
<br>
<p>
<font size="4"><b><u>Prelisten and output</u></b></font>
<ul><ul>
</p><p>
Normal play ist already a prelisten mode because every cut
and every gain modification is played as it will be saved.
In addition there are some buttons to prelisten the selection
boundaries <b>before</b> cutting:
</p><p>
<b>[=>I..]</b> / F5 - play 2 seconds <b>to</b> the selection <b>beginning</b><br>
<b>[I=>..]</b> / F6 - play 2 seconds <b>from</b> the selection <b>beginning</b><br>
<b>[..=>I]</b> / F7 - play 2 seconds <b>to</b> the selection <b>end</b><br>
<b>[..I=>]</b> / F8 - play 2 seconds <b>from</b> the selection <b>end</b><br>
<b>[=>I...I=>]</b> / F9 - play the selection <b>as cut</b> (2 secs before and after)
</p><p>
After finishing prelisten the cursor returns to the previous position.
</p><p>
While normal play two of the prelisten buttons change their function to provide <b>Fast Play</b>.
The buttons show the symbols <b>[>> -]</b> and <b>[>> +]</b> and can be used to adjust the
speed of Fast Play in small steps. For faster operation it's recommended to use the keys F7 and F8.
</p><p>
<b>A created audio file</b> can either be the whole shown data
(<b>'Save all...'</b>) or only the range of the selection (<b>'Save selection...'</b>).
You can also save multiple pieces at once with the <b>'Save split...'</b> function.
It creates seperate files for every range <b>between two cues</b>.
