    wD & DѨM

    mp3DirectCut is tested with a large amount of different MP3
    types. In some cases it can still behave strange or crash.
    As there are many differences in the apearence of MPEG files
    it is not easy to predict which errors might occur.
    

      - The main MP3 graph does not show the correct audio level.
        But this is not an error! The graph contains only higher
        frequencies. It can also be too high or too low over the
        whole file.

      - Visualisation of Layer 2 is much worse than Layer 3. What
        you see on MP2 has next to nothing to do with an audio level.
        Please, don't complain if MP2 silence is shown as mountains.

      - VBR files are editable but are not visualized correctly.
        Its recommended to cut and fade VBR files "by ear" and
        using the "Set begin" and "Set end" buttons.

      - The last two or three frames can only be selected together.

      - The Duration threshold on silence detection is not accurate.
        Silences below 2 seconds are not detected reliably.

      - Cuts in MP3 files may sound noisy or squeaky, especially
        at lower bitrates. This is also not an error but caused by
        the "bit reservoir" used by most MP3. Originally MP3 is not
        made for cutting, because some frames in a row can depend
        on each other. Solution: make cuts at silent positions and
        they will be less perceptable.

      - If the computer is too slow for decoding in realtime the
        player will hang. Try to use higher values for the play
        buffers at the preferences and zoom in a step.
        You should also make the window smaller.
        If the sound is noisy or interrupted try also setting the
        buffer to a higher value (more "reliable") and vary the
        Maximum wave buffer value. Use the "high priority" option
        only if your system is fast enough for playing!

      - If the MP3 file is not on a local harddrive playing
        and scrolling the file may be interrupted.

      - Handling large MP3 files or a lot of MP3 files can cause
        Windows's file cache growing and keeping the reserved
        memory. Since a function that cleans the Windows file
        cache is missing you should prevent Windows from using all
        the RAM for file caching (e.g. with Cacheman).

      - If the file is scrolled or the selection is changed with
        the mouse the graph sometimes could show trash and the MP3
        information may be incorrect. In these cases the program has
        lost the frame synchronization. Move further to re-synchronize.

      - In some rare cases the program crashed a whole system,
        especially at intense scrolling while an MP3 was playing.

      - Saving a selection or splitting a file may in some cases work
        with incorrect ranges. It's recommended to check saved
        selections and split files.

      - The Split function should be used for separating large
        files into different tracks. It is not made for Split+Join
        purposes.

      - 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. I think this depends
        on different Windows versions and possible file corruptions.

      - If the ID3v2 Tag is bigger than about 58 KByte it will
        not be saved.

      - Extra duration informations (like a length tag in ID3v2) are
        not adapted by the program. If you save a part of a file
        and keep the tag, the new shorter file will have the wrong
        duration information of the original file.

      - There are reports that the program does not work at all and
        opens with a General Protection Fault.
