GNoise v0.1.15 INTRO
--------------------
    GNoise is a GTK+ based wave file editor. It uses a display cache and a
    double-buffered display for maximum speed with large files. It supports
    common editing functions such as cut, copy, paste, fade in/out, reverse,
    interpolate, normalize and more with unlimited undo.

    The primary design objectives are stability, speed, and the ability to
    handle big files (i.e. 70MB ripped CD tracks) easily. In fact GNoise has
    been reported to work with >500MB files although the author doesn't
    happen to have any wave files that size laying about :)

    See the TODO list for things I'm considering adding/fixing in the near
    future. Feel free to send me patches or email, especially for any bugs
    you encounter.

    The custom gtk widgets within GNoise support setting colors through the
    normal gtkrc mechanisms, there is a sample gtkrc file included, just
    drop it in ~/.gnoise and edit it to your likings.

    Note that GNoise is a destructive editor: all editing operates directly
    on the soundfile, work on a copy of something you really don't want to
    lose. Note also that you should not mix the use of the disable undo
    option on different edits within an editing session (ie. if you start
    editing a file with undo disabled then leave undo's disabled until you
    close the file, at which point you can turn undo on and re-open the file
    if you wish to edit with undo capability).


BUILDING
--------
    ./configure
    make

    To build GNoise optimized for your archtecture you can for example do:
    CFLAGS="-march=athlon -mcpu=athlon" ./configure
      or if you are building the rpm:
    CFLAGS="-march=athlon -mcpu=athlon" rpm -ba gnoise.spec


USING
-----
    - A left click unselects any selections

    - A right click sets the playline

    - A left drag will create a new selection unless you start it on the end
      of a pre-existing selection (the mouse cursor will turn into a double
      headed arrow) in which case it extends the selection

    - Adding a new marker inserts a marker at the current play line
      position. Markers can also be added at fixed intervals through the
      markers dialog box.

    - Clicking play begins playback. If there is a disjoint selection (the
      starting and ending of the selections for all channels don't match) or
      no selection, playback will commence at the the playline and play to
      the end of the file. If the selection begin and end is the same for
      all channels (non-disjoint) then just the selection will be played.

    - The + zooms in, - zooms out, and Selection zooms to, uh, the selection.
      Yes, you can zoom in to single sample resolution.

    - Clicking stop does what you think as well

    - Recording: Set the parameters in the dialog, give a filename and hit
      record. Adjust levels and input device using gmix or your favorite
      mixer program. For best results, make sure none of the source material
      clips (the buttons above the levels). If you don't like the take, just
      hit stop, then hit record again and it will record over (not append
      to!) the previous take.

    - Edits modify the current selection

    - When you first open a file GNoise will (optionally) create a display
      cache file so it can draw it very quickly (also know as a 'peaks' file
      in Sound Forge terminology). This cache file is stored in the same
      directory as the wave file itself and is given the name '.<orignal
      file name>.dcache'. By default, all zoom levels below 1:512 will not
      be cached, but generated on the fly.
