Cut ur favourite s songs

Only the split points with a Cue flag are saved to the Cue sheet file. If a split point does not
have a Cue flag, it will not be saved. A flag can be set easily by CTRL+Q or in the
Names and properties dialog. To set multiple flags, you can use the function
"Set Cue flags for all simple split points" in the Edit menu.
When loading a Cue sheet, the flags will be set automatically.
If an edit point has a Cue flag set, it is displayed as dotted line.

<b>Why can't the program record in 44.1 kHz Stereo at 128 kbit/sec or more?</b>

<td bgcolor="#fefefe" valign="top"><font face="Arial">
It can. But you seem to use a limited ACM (usually to 56 or 128 kbps). Get the free Lame encoder, copy the
"Lame_enc.dll" to your Windows or mp3DirectCut folder and switch to Lame in the encoder settings.

This problem is not mp3DirectCut related.
If the VU meter does not move on record, you should check the signal flow and the input level
by the mixer applications of the system and your sound device. In mp3DirectCut you only have
to choose the correct Wave-in device in the settings.

<b>Why are some silences shown with a constant high level (since version 2.01) ?</b>
</font>
</td>
<td bgcolor="#fefefe" valign="top"><font face="Arial">
This problem can occur on files encoded by Lame to Joint stereo but may also concern other formats.
It seems at frames with absolute silence, the main gain of an mpeg frame is irrelevant, and some encoders
set it to a mad value. If mp3DirectCut's display would try to correct this, it could occur that also the level
of some frames with normal level is not shown (happened in earlier versions). So we have to live
with those ugly silences. But they can even be cut, as they are only silences ;)

<td bgcolor="#fefefe" valign="top"><font face="Arial">
It's no longer necessarry since mp3DirectCut has virtual Cut, Copy & Paste.
Open a second instance of the program where you copy the part you want to
append. Then paste the selection the end of the other track. "Save all..."
creates the combined file. You can also paste multiple selections. Before
saving, the program does not copy real audio data but only references.
So you must keep every file until you saved the result file.

</td>
<td bgcolor="#fefefe" valign="top"><font face="Arial">
Vorbis seems much more difficult to cut than MP3.
An MP3 can be cut nearly everywhere and it's still playable. Cutting an
Ogg file without adapting anything here and there will produce broken files.
By now I could not find an understandable documentation of a structure in Vorbis files.

mp3DirectCut is tested with many different MP3/MP2

As there are many differences in the apearence of MPEG audio

Cuts in MP3 files may sound noisy or squeaky, especially at lower bitrates. This is not an error.
The MP3 format originally is not made for cutting, because some frames in a row often depend on each others.
Solution: make cuts at silent positions and the noises will be less perceptable.
<li>
If your computer is too slow for decoding in realtime and working the graphics, the player will hang.
Set the <b>"frames per buffer"</b> value to max (8). Zoom in a step.
You should also make the window smaller. If your machine is fast enough but the sound is noisy or
interrupted, try varying the <b>"Maximum wave buffer"</b>. The <b>"High priority"</b> option may
reduce sound interruptions if other cpu intense applications work in the background. But not if your
system is too slow for real time playback!
<li>
If the MP3 file is not on a local harddrive, playing and scrolling the file may be interrupted.
<li>
Large files may fill up Windows' file cache. It is (generally) recommended to prevent Windows
from using all the RAM for file caching (e.g. with the Freeware Cacheman).

Some users reported that trying to save selections from large files after a file position of about
60..80 MB caused the program or the system to crash. Others reported, saving files of seven
hours works excellent. As there isn't an extensive file corruption management unforeseen errors
may occur.

In rare cases the program crashed a whole system, especially at intense
scrolling while playing or after frequent play/stop with ACM usage.
<li>
In earlier versions, there were reports that the program did not work at all and opened with a General Protection
Fault. In these cases try to close other processes and applications which may interfere with this one.
