<body bgcolor='#efefef' text='black' link='blue' vlink='#551A8B' alink='red'>
<a href='#toc'>Table of Contents</a><p>
<h2><a name='sect0' href='#toc0'>Name</a></h2>
auedit - graphically record and edit audio files
<h2><a name='sect1' href='#toc1'>Synopsis</a></h2>
<b>auedit</b> [-audio
<i>servername</i>] [<b>-toolkitoption ...</b>] [filename]
<h2><a name='sect2' href='#toc2'>Description</a></h2>
<i>auedit</i> provides an X-based
window-oriented interface allowing the user to record and edit audio files.
The editing features available include:
<dl>
<dt><b>o</b></dt>
<dd>Cutting, copying, pasting, and
mixing within a single <i>auedit</i> instance or between multiple <i>auedit</i> instances.
</dd>
<dt><b>o</b></dt>
<dd>Changing the amplitude of an interval. </dd>
<dt><b>o</b></dt>
<dd>Reversing an interval. </dd>
<dt><b>o</b></dt>
<dd>Fading in
or out an interval. </dd>
</dl>
<h2><a name='sect3' href='#toc3'>Auedit and the Athena Widget Set</a></h2>
<i>auedit</i> uses the X Toolkit
Intrinsics and the Athena Widget Set. For more information, see the Athena
Widget Set documentation.
<h2><a name='sect4' href='#toc4'>Screen Layout</a></h2>
<i>auedit</i> starts out with a single window
divided into several areas:
<dl>
<dt><b>o</b></dt>
<dd>A collection of drop-down menus and command
buttons. </dd>
<dt><b>o</b></dt>
<dd>A volume indicator and control slider. </dd>
<dt><b>o</b></dt>
<dd>The audio file represented
as a wave form. If the audio data contains multiple tracks, the tracks
will be displayed in ascending order. For stereo data, the convention is
left track, then right track. </dd>
<dt><b>o</b></dt>
<dd>A set of indicators displaying the interval
start, duration, and end and the current position. These indicators are
in units of minutes, seconds, and hundredths of seconds. </dd>
<dt><b>o</b></dt>
<dd>Buttons to play,
stop, and pause the audio. </dd>
<dt><b>o</b></dt>
<dd>Two menus indicating the current file and data
formats. </dd>
<dt><b>o</b></dt>
<dd>Two editable fields containing the current frequency and the audio
file comment. </dd>
</dl>
<h2><a name='sect5' href='#toc5'>Intervals</a></h2>
Many functions in <i>auedit</i> operate on a range of audio
data called an <b>interval</b>. The initial interval encompasses all of the audio
data. The interval is indicated within the wave form by two solid, vertical
lines. The left marker indicates the start of the interval. The right marker
indicates the end of the interval. To select an interval of audio data,
use the mouse to move the interval markers in the wave form. Pressing a
mouse button in the wave form will select the marker closest to the mouse
position. That marker may then be dragged to the desired location in the
wave form. Note that the markers may not cross over each other.
<h2><a name='sect6' href='#toc6'>Playing
an Interval</a></h2>
To play an interval, click on the Play button (the one with
the triangle on its side). The audio data delimited by the start and end
markers will be played. A dashed vertical line will indicate the approximate
position of the data currently being played. To stop playing, click on
the Stop button (the one containing a solid square). Clicking on Pause (the
button containing two vertical, parallel lines) will pause the playing.
To resume, click on Pause again. The volume slider controls the play volume.
The interval is played at the frequency specified by the <b>Frequency</b> field.
Note that while data is being played, most other functions are disabled.
<h2><a name='sect7' href='#toc7'>the File Menu</a></h2>
<dl>
<dt>New...</dt>
<dd>Initializes <i>auedit</i> with an empty file. You will be prompted
for the number of tracks for the new file. </dd>
<dt>Load...</dt>
<dd>Loads a file. You will be
prompted for the file name. </dd>
<dt>Save</dt>
<dd>Saves the current file. A backup file will
be created by appending a tilde (~) to the current file name. The file
format, data format, frequency and comment are used when saving the file.
</dd>
<dt>Save as...</dt>
<dd>Saves the current file under a new name. You will be prompted for
the file name. The file format, data format, frequency and comment are
used when saving the file. </dd>
<dt>Save interval...</dt>
<dd>Saves the interval to a file. You
will be prompted for a file name. The file format, data format, frequency
and comment are used when saving the file. </dd>
<dt>Revert</dt>
<dd>Discards all changes made
since the last save and restores the data to its state following the last
save. </dd>
<dt>Exit</dt>
<dd>Exits <i>auedit</i>. If there have been changes made to the current file
that have not been saved, you will be asked if you wish to save them. </dd>
</dl>
<h2><a name='sect8' href='#toc8'>the
Edit Menu</a></h2>
The cut, copy, and paste commands in the edit menu transfer data
to and from a selection buffer. This buffer is shared between all instances
of <i>auedit</i>. This means that you can cut or copy data from one instance of
<i>auedit</i> and paste it into another instance. The only restriction is that
the audio data in both instances must have the same number of tracks. When
transferring data between instances of differing frequencies, the data
will be converted to the frequency of the destination. This can be used
to change the frequency of the data in a single instance of <i>auedit</i>. First,
cut the data whose frequency you wish to change. Then change the <b>Frequency</b>
field to the desired frequency. Finally, paste the data back in. The frequency
of the data will be converted to the frequency specified in the <b>Frequency</b>
field.
<dl>
<dt>Cut</dt>
<dd>Moves the interval to the selection buffer. </dd>
<dt>Copy</dt>
<dd>Copies the interval
to the selection buffer. </dd>
<dt>Paste insert</dt>
<dd>Inserts the selection buffer at the
point marked by the start marker. </dd>
<dt>Paste replace</dt>
<dd>Replaces the data at the
point marked by the start marker with the data from the selection buffer.
</dd>
<dt>Paste mix</dt>
<dd>Mixes the data at the point marked by the start marker with the
data from the selection buffer. The mixing function is an average. </dd>
<dt>Undo</dt>
<dd>Undoes
the last operation that modified the audio data. This includes effects
operations in addition to editing operations. If the last operation was
an <b>Undo</b> then the undo is undone, restoring the data to the state prior
to the first undo. </dd>

<dt><b>o</b></dt>
<dd>A duration field. This is the maximum
duration of the recording in seconds. </dd>
