Introduction
mp3DirectCut is a frame-based editor for MPEG audio (Layers 2 and 3) and AAC. It can cut, copy,
to change the volume without re-encoding. This makes mp3DirectCut very fast and avoids loss
audio quality. The program offers easier navigation, even in large files (up to 4 GB), and
it provides a quick visualization of compressed audio data. It can handle Cue sheets and allows splitting.
a file in the reference positions. In addition, it can directly record and encode to MP3 from your
audio input device.

Basic settings
To play the files, the program uses a decoding library. For MP3 this is generally
the planned system ACM Codec (Windows since XP contains by default). The mpglib.dll can be used
for the game MP2 and, alternatively, for MP3. It must be in the program folder or system path
For example, the Windows folder. To play, you need the librelibfaad2.dll (also working: a
new name ff_libfaad2.dll of ffdshow) in the program or system folder path. The libfaad2.dll
it requires the MSVC 9.0 runtime.
Change to your preferred MP3 decoder in the device settings (Settings > Configure >
Devices). In the output devices section, you can select a waveform device and adjust the
number of frames that are decoded for each buffer ranges between 'fast' (1 frame) and 'reliable' (8)
frames). On slower machines, set a higher value. For a quick response from the
graphics, select a lower value. The default value is 4.
The language program can be adjusted in the Operation tab (Settings > Configure > Operation). In the list,
select your language if present. Language files must be in a subdirectory 'Languages' of the
mp3DirectCut folder. If no language is selected or found, the program will also search in its
Your own folder for a language file. So you can also activate your language without having to maintain it

Since mp3DirectCut is designed to handle large files, there are many ways to reach a

to cut, copy or paste. A selection of points is for the creation of keys or change points of

The value of 'After a jump detection pause' can be used to speed up the process of

For example, if you know that all the tracks on your CD image are 3 minutes or longer, you could set
this value in 150 seconds.
Recording
For direct MP3 recording, you need either a codec with ACM encoding capability or
the Lame Encoder DLL (available through the Lame project homepage). It is important to choose a
base file name. Your recordings will be saved under this name. Please note that there will be no
query to overwrite existing files! If you select Add date and time of each recorded file
it will have a date and time in its file name.
To start the recording, press [Rec]. You can then see the audio input level at the
VU meter. After pressing [Play], the file begins to be written. With selected Append data.
